E-mail:fg@thp.uni-koeln.de,hehl@thp.uni-koeln.de ABSTRACT We give a short outline,in Sec.2,of the historical development of the gauge idea as applied to internal (U (1),SU (2),...)and external (R 4,SO (1,3),...)symmetries and stress the fundamental importance of the corresponding con-served currents.In Sec.3,experimental results with neutron interferometers in the gravitational field of the earth,as interpreted by means of the equivalence principle,can be predicted by means of the Dirac equation in an accelerated and rotating reference ing the Dirac equation in such a non-inertial frame,we describe how in a gauge-theoretical approach (see Table 1)the Einstein-Cartan theory,residing in a Riemann-Cartan spacetime encompassing torsion and curvature,arises as the simplest gravitational theory.This is set in con-trast to the Einsteinian approach yielding general relativity in a Riemannian spacetime.In Secs.4and 5we consider the conserved energy-momentum cur-rent of matter and gauge the associated translation subgroup.The Einsteinian teleparallelism theory which emerges is shown to be equivalent,for spinless mat-ter and for electromagnetism,to general relativity.Having successfully gauged the translations,it is straightforward to gauge the four-dimensional affine group R 4⊃×GL (4,R )or its Poincar´e subgroup R 4⊃×SO (1,3).We briefly report on these results in Sec.6(metric-affine geometry)and in Sec.7(metric-affine field equations (111,112,113)).Finally,in Sec.8,we collect some models,cur-rently under discussion,which bring life into the metric-affine gauge framework developed.Contents1.Introduction2.Remarks on the history of the gauge idea2.1.General relativity and Weyl’s U(1)-gauge theory2.2.Yang-Mills and the structure of a gauge

theory(GR)from the point of view of classical gaugefield theory?This is the question underlying our present considerations.The answer•leads to a better understanding of the interrelationship between the metric and affine properties of spacetime and of the group structure related to gravity.Furthermore,it •suggests certain classicalfield-theoretical generalizations of Einstein’s theory,such as Einstein–Cartan theory,Einsteinian teleparallelism theory,Poincar´e gauge theory, Metric-Affine Gravity,that is,it leads to a deepening of the insight won by GR.We recently published a fairly technical review article on our results29.These lectures can be regarded as a down-to-earth introduction into that subject.We refrain from citing too many articles since we gave an overview a of the existing literature in ref.(29).2.Remarks on the history of the gauge idea2.1.General relativity and Weyl’s U(1)-gauge theorySoon after Einstein in1915/16had proposed his gravitational theory,namely general relativity(GR),Weyl extended it in1918in order to include–besides grav-itation–electromagnetism in a unified way.Weyl’s theoretical concept was that of recalibration or gauge invariance of length.In Weyl’s opinion,the integrability of length in GR is a remnant of an era dominated by action-at-a-distance theories which should be abandoned.In other words,if in GR we displace a meter stick from one point of spacetime to another one,it keeps its length,i.e.,it can be used as a standardof length throughout spacetime;an analogous argument is valid for a clock.In con-trast,Weyl’s unified theory of gravitation and electromagnetism of1918is set up in such a way that the unified Lagrangian is invariant under recalibration or re-gauging.For that purpose,Weyl extended the geometry of spacetime from the(pseudo-) Riemannian geometry with its Levi-Civita connectionΓ{}αβto a Weyl space with an additional(Weyl)covectorfield Q=Qαϑα,whereϑαdenotes thefield of coframes of the underlying four-dimensional differentiable manifold.The Weyl connection one-form reads1ΓWαβ=Γ{}αβ+ψ,D ψA)mat L (DJ=0A theorem local gauge symmetry coupling A Noether’s J <dJ=0of Lagrangian(d ψ),L mat ψgauge potentialsymmetry rigid ConservedJA(connection)current Fig.1.The structure of a gauge theory `a la Yang-Mills is depicted in this diagram,which is adapted from Mills 53.Let us quote some of his statements on gauge theories:‘The gauge principle,which might also be described as a principle of local symmetry ,is a statement about the invariance properties of physical laws.It requires that every continuous symmetry be a local symmetry ...’‘The idea at the core of gauge theory...is the local symmetry principle:Every continuous symmetry of nature is a local symmetry.’The history of gauge theory has been traced back to its beginnings by O’Raifeartaigh 69,who also gave a compact review of its formalism 68.the electromagnetic potential is an appendage to the Dirac field and not related to length recalibration as Weyl originally thought.2.2.Yang-Mills and the structure of a gauge theoryYang and Mills,in 1954,generalized the Abelian U (1)-gauge invariance to non-Abelian SU (2)-gauge invariance,taking the (approximately)conserved isotopic spin current as their starting point,and,in 1956,Utiyama set up a formalism for the gauging of any semi-simple Lie group,including the Lorentz group SO (1,3).The latter group he considered as essential in GR.We will come back to this topic below.In any case,the gauge principle historically originated from GR as a concept for removing as many action-at-a-distance concept as possible –as long as the group under consideration is linked to a conserved current.This existence of a conserved current of some matter field Ψis absolutely vital for the setting-up of a gauge theory.In Fig.1we sketched the structure underlying a gauge theory:A rigid symmetry ofa Lagrangian induces,via Noether’s theorem,a conserved current J ,dJ =0.It can happen,however,as it did in the electromagnetic and the SU (2)-case,that a conserved current is discovered first and then the symmetry deduced by a kind of a reciprocal Noether theorem (which is not strictly valid).Generalizing from the gauge approach to the Dirac-Maxwell theory,we continue with the following gauge procedure:Extending the rigid symmetry to a soft symmetry amounts to turn the constant group parameters εof the symmetry transformation on the fields Ψto functions of spacetime,ε→ε(x ).This affects the transformation behavior of the matter La-grangian which usually contains derivatives d Ψof the field Ψ:The soft symmetry transformations on d Ψgenerate terms containing derivatives dε(x )of the spacetime-dependent group parameters which spoil the former rigid invariance.In order to coun-terbalance these terms,one is forced to introduce a compensating field A =A i a τa dx i (a =Lie-algebra index,τa =generators of the symmetry group)–nowadays called gauge potential –into the theory.The one-form A turns out to have the mathematical mean-ing of a Lie-algebra valued connection .It acts on the components of the fields Ψwith respect to some reference frame,indicating that it can be properly represented as the connection of a frame bundle which is associated to the symmetry group.Thereby it is possible to replace in the matter Lagrangian the exterior derivative of the matter field by a gauge-covariant exterior derivative,d −→A D :=d +A ,L mat (Ψ,d Ψ)−→L mat (Ψ,A D Ψ).(4)This is called minimal coupling of the matter field to the new gauge interaction.The connection A is made to a true dynamical variable by adding a corresponding kinematic term V to the minimally coupled matter Lagrangian.This supplementary term has to be gauge invariant such that the gauge invariance of the action is kept.Gauge invariance of V is obtained by constructing it from the field strength F =A DA ,V =V (F ).Hence the gauge Lagrangian V ,as in Maxwell’s theory,is assumed to depend only on F =dA ,not,however,on its derivatives dF,d ∗d F,...Therefore the field equation will be of second order in the gauge potential A .In order to make it quasilinear,that is,linear in the second derivatives of A ,the gauge Lagrangian must depend on F no more than quadratically.Accordingly,with the general ansatz V =F ∧H ,where the field momentum or “excitation”H is implicitly defined by H =−∂V /∂F ,the H has to be linear in F under those circumstances.By construction,the gauge potential in the Lagrangians couples to the conserved current one started with –and the original conservation law,in case of a non-Abelian symmetry,gets modified and is only gauge covariantly conserved,dJ =0−→A DJ =0,J =∂L mat /∂A.(5)The physical reason for this modification is that the gauge potential itself contributes a piece to the current,that is,the gauge field (in the non-Abelian case)is charged.For instance,the Yang-Mills gauge potential B a carries isotopic spin,since the SU(2)-group is non-Abelian,whereas the electromagnetic potential,being U(1)-valued and Abelian,is electrically uncharged.2.3.Gravity and the Utiyama-Sciama-Kibble approachLet us come back to Utiyama(1956).He gauged the Lorentz group SO(1,3), inter ing some ad hoc assumptions,like the postulate of the symmetry of the connection,he was able to recover GR.This procedure is not completely satisfactory, as is also obvious from the fact that the conserved current,linked to the Lorentz group,is the angular momentum current.And this current alone cannot represent the source of gravity.Accordingly,it was soon pointed out by Sciama and Kibble (1961)that it is really the Poincar´e group R4⊃×SO(1,3),the semi-direct product of the translation and the Lorentz group,which underlies gravity.They found a slight generalization of GR,the so-called Einstein-Cartan theory(EC),which relates–in a Einsteinian manner–the mass-energy of matter to the curvature and–in a novel way –the material spin to the torsion of spacetime.In contrast to the Weyl connection (1),the spacetime in EC is still metric compatible,erned by a Riemann-Cartan b (RC)geometry.Torsion is admitted according to1ΓRCαβ=Γ{}αβ−b The terminology is not quite uniform.Borzeskowski and Treder9,in their critical evaluation of different gravitational variational principles,call such a geometry a Weyl-Cartan gemetry.secondary importance in some sense that some particularΓfield can be deduced from a Riemannian metric...”In this vein,we introduce a linear connectionΓαβ=Γiαβdx i,(7) with values in the Lie-algebra of the linear group GL(4,R).These64components Γiαβ(x)of the‘displacement’field enable us,as pointed out in the quotation by Einstein,to get rid of the rigid spacetime structure of special relativity(SR).In order to be able to recover SR in some limit,the primary structure of a con-nection of spacetime has to be enriched by the secondary structure of a metricg=gαβϑα⊗ϑβ,(8) with its10componentfields gαβ(x).At least at the present stage of our knowledge, this additional postulate of the existence of a metric seems to lead to the only prac-ticable way to set up a theory of gravity.In some future time one may be able to ‘deduce’the metric from the connection and some extremal property of the action function–and some people have tried to develop such type of models,but without success so far.2.4.E.Cartan’s analysis of general relativity and its consequencesBesides the gauge theoretical line of development which,with respect to gravity, culminated in the Sciame-Kibble approach,there was a second line dominated by E.Cartan’s(1923)geometrical analysis of GR.The concept of a linear connection as an independent and primary structure of spacetime,see(7),developed gradually around1920from the work of Hessenberg,Levi-Civita,Weyl,Schouten,Eddington, and others.In its full generality it can be found in Cartan’s work.In particular, he introduced the notion of a so-called torsion–in holonomic coordinates this is the antisymmetric and therefore tensorial part of the components of the connection–and discussed Weyl’s unifiedfield theory from a geometrical point of view.For this purpose,let us tentatively callgαβ,ϑα,Γαβ (9)the potentials in a gauge approach to gravity andQαβ,Tα,Rαβ (10)the correspondingfield ter,in Sec.6,inter alia,we will see why this choice of language is appropriate.Here we definednonmetricity Qαβ:=−ΓD gαβ,(11) torsion Tα:=ΓDϑα=dϑα+Γβα∧ϑβ,(12)curvature Rαβ:=′′ΓDΓαβ′′=dΓαβ−Γαγ∧Γγβ.(13)Then symbolically we haveQαβ,Tα,Rαβ ∼ΓD gαβ,ϑα,Γαβ .(14)By means of thefield strengths it is straightforward of how to classify the space-time manifolds of the different theories discussed so far:GR(1915):Qαβ=0,Tα=0,Rαβ=0.(15)Weyl(1918):Qγγ=0,Tα=0,Rαβ=0.(16)EC(1923/61):Qαβ=0,Tα=0,Rαβ=0.(17) Note that Weyl’s theory of1918requires only a nonvanishing trace of the nonmetric-ity,the Weyl covector Q:=Qγγ/4.For later use we amend this table with the Einsteinian teleparallelism(GR||),which was discussed between Einstein and Car-tan in considerable detail(see Debever12)and with metric-affine gravity29(MAG), which presupposes the existence of a connection and a(symmetric)metric that are completely independent from each other(as long as thefield equations are not solved): GR||(1928):Qαβ=0,Tα=0,Rαβ=0.(18)MAG(1976):Qαβ=0,Tα=0,Rαβ=0.(19) Both theories,GR||and MAG,were originally devised as unifiedfield theories with no sources on the right hand sides of theirfield equations.Today,however,we understand them10,29as gauge type theories with well-defined sources.Cartan gave a beautiful geometrical interpretation of the notions of torsion and curvature.Consider a vector at some point of a manifold,that is equipped with a connection,and displace it around an infinitesimal(closed)loop by means of the connection such that the(flat)tangent space,where the vector‘lives’in,rolls without gliding around the loop.At the end of the journey29the loop,mapped into the tangent space,has a small closure failure,i.e.a translational misfit.Moreover,in the case of vanishing nonmetricity Qαβ=0,the vector underwent a small rotation or–if no metric exists–a small linear transformation.The torsion of the underlying manifold is a measure for the emerging translation and the curvature for the rotation(or linear transformation):translation−→torsion Tα(20) rotation(lin.transf.)−→curvature Rαβ.(21) Hence,if your friend tells you that he discovered that torsion is closely related to electromagnetism or to some other nongravitationalfield–and there are many such ‘friends’around,as we can tell you as referees–then you say:‘No,torsion is related to translations,as had been already found by Cartan in1923.’And translations–weFig.2.The neutron interferometer of the COW-experiment11,18:A neutron beam is split into two beams which travel in different gravitational potentials.Eventually the two beams are reunited and their relative phase shift is measured.hope that we don’t tell you a secret–are,via Noether’s theorem,related to energy-momentum c,i.e.to the source of gravity,and to nothing else.We will come back to this discussion in Sec.4.For the rest of these lectures,unless stated otherwise,we will choose the frame eα,and hence also the coframeϑβ,to be orthonormal,that is,g(eα,eβ)∗=oαβ:=diag(−+++).(22) Then,in a Riemann-Cartan space,we have the convenient antisymmetriesΓRCαβ∗=−ΓRCβαand R RCαβ∗=−R RCβα.(23) 3.Einstein’s and the gauge approach to gravity3.1.Neutron matter waves in the gravitationalfieldTwenty years ago a new epoch began in gravity:C olella-O verhauser-W erner measured by interferometric methods a phase shift of the wave function of a neutron caused by the gravitationalfield of the earth,see Fig.2.The effect could be predicted by studying the Schr¨o dinger equation of the neutron wave function in an external Newtonian potential–and this had been verified by experiment.In this sense noth-ing really earth-shaking happened.However,for thefirst time a gravitational effect had been measured the numerical value of which depends on the Planck constant¯h. Quantum mechanics was indispensable in deriving this phase shiftm2gθgrav=gpath 1path 2zx~ 2 cm~ 6 cmA Fig.3.COW experiment schematically.the neutron beam itself is bent into a parabolic path with 4×10−7cm loss in altitude.This yields,however,no significant influence on the phase.In the COW experiment,the single-crystal interferometer is at rest with respect to the laboratory,whereas the neutrons are subject to the gravitational potential.In order to compare this with the effect of acceleration relative to the laboratory frame,B onse and W roblewski 8let the interferometer oscillate horizontally by driving it via a pair of standard loudspeaker magnets.Thus these experiments of BW and COW test the effect of local acceleration and local gravity on matter waves and prove its equivalence up to an accuracy of about 4%.3.2.Accelerated and rotating reference frameIn order to be able to describe the interferometer in an accelerated frame,we first have to construct a non-inertial frame of reference.If we consider only mass points ,then a non-inertial frame in the Minkowski space of SR is represented by a curvilinear coordinate system,as recognized by Einstein 13.Einstein even uses the names ‘curvilinear co-ordinate system’and ‘non-inertial system’interchangeably.According to the standard gauge model of electro-weak and strong interactions,a neutron is not a fundamental particle,but consists of one up and two down quarks which are kept together via the virtual exchange of gluons,the vector bosons of quantum chromodynamics,in a permanent ‘confinement phase’.For studying the properties of the neutron in a non-inertial frame and in low-energy gravity,we may disregard its extension of about 0.7fm ,its form factors,etc.In fact,for our purpose,it is sufficient to treat it as a Dirac particle which carries spin 1/2but is structureless otherwise .Table 1.Einstein’s approach to GR as compared to the gauge approach:Used are a mass point m or a Dirac matter field Ψ(referred to a local frame),respectively.IF means inertial frame,NIF non-inertial frame.The table refers to special relativity up to the second boldface horizontal line.Below,gravity will be switched on.Note that for the Dirac spinor already the force-free motion in an inertial frame does depend on the mass parameter m .gauge approach (→COW)elementary object in SRDirac spinor Ψ(x )Cartesian coord.system x ids 2∗=o ij dx i dx jforce-freemotion in IF (iγi ∂i −m )Ψ∗=0arbitrary curvilinear coord.system x i′force-free motion in NIF iγαe i α(∂i +Γi )−m Ψ=0Γi :=1non-inertial objects ϑα,Γαβ=−Γβα16+24˜R(∂{},{})=020global IF e i α,Γi αβ ∗=(δαi ,0)switch on gravity T =0,R =0Riemann −Cartang ij |P ∗=o ij , i jk |P ∗=0field equations 2tr (˜Ric )∼mass GR2tr (Ric )∼massT or +2tr (T or )∼spinECA Dirac particle has to be described by means of a four-component Dirac spinor. And this spinor is a half-integer representation of the(covering group SL(2,C)of the)Lorentz group SO(1,3).Therefore at any one point of spacetime we need an orthonormal reference frame in order to be able to describe the spinor.Thus,as soon as matterfields are to be represented in spacetime,the notion of a reference system has to be generalized from Einstein’s curvilinear coordinate frame∂i to an arbitrary, in general anholonomic,orthonormal frame eα,with eα·eβ=oαβ.It is possible,of course,to introduce in the Riemannian spacetime of GR arbi-trary orthonormal frames,too.However,in the heuristic process of setting up the fundamental structure of GR,Einstein and his followers(for a recent example,see the excellent text of d’Inverno36,Secs.9and10)restricted themselves to the discussion of mass points and holonomic(natural)frames.Matter waves and arbitrary frames are taboo in this discussion.In Table1,in the middle column,we displayed the Ein-steinian method.Conventionally,after the Riemannian spacetime has been found and the dust settled,then electrons and neutron and what not,and their corresponding wave equations,are allowed to enter the scene.But before,they are ignored.This goes so far that the well-documented experiments of COW(1975)and BL(1983)–in contrast to the folkloric Galileo experiments from the leaning tower–seemingly are not even mentioned in d’Inverno36(1992).Prugoveˇc ki79,one of the lecturers here in Erice at our school,in his discussion of the classical equivalence principle,recognizes the decisive importance of orthonormal frames(see his page52).However,in the end,within his‘quantum general relativity’framework,the good old Levi-Civita connection is singled out again(see his page 125).This is perhaps not surprising,since he considers only zero spin states in this context.We hope that you are convinced by now that we should introduce arbitrary or-thonormal frames in SR in order to represent non-inertial reference systems for mat-ter waves–and that this is important for the setting up of a gravitational gauge theory2,42.The introduction of accelerated observers and thus of non-inertial frames is somewhat standard,even if during the Erice school one of the lecturers argued that those frames are inadmissible.Take the text of Misner,Thorne,and Wheeler57.In their Sec.6,you willfind an appropriate discussion.Together with Ni30and in our Honnef lectures27we tailored it for our needs.Suppose in SR a non-inertial observer locally measures,by means of the instru-ments available to him,a three-acceleration a and a three-angular velocityω.If the laboratory coordinates of the observer are denoted by x x as the correspond-ing three-radius vector,then the non-inertial frame can be written in the succinct form30,27eˆ0=1x/c2 ∂c×B∂A.(25)Here ‘naked’capital Latin letters,A,...=ˆ1,ˆ2,ˆ3,denote spatial anholonomic com-ponents.For completeness we also display the coframe,that is,the one-form basis,which one finds by inverting the frame (25):ϑˆ0= 1+a ·c 2 dx 0,ϑA =dx c ×A dx A +N 0.(26)In the (3+1)-decomposition of spacetime,N and Ni βαdx0ˆ0A =−Γc 2,Γ0BA =ǫABCωC i α,with e α=e i ,into an anholonomic one,then we find the totallyanholonomic connection coefficients as follows:Γˆ0ˆ0A =−Γˆ0A ˆ0=a A x /c 2 ,Γˆ0AB =−Γˆ0BA =ǫABC ωC x /c 2 .(28)These connection coefficients (28)will enter the Dirac equation referred to a non-inertial frame.In order to assure ourselves that we didn’t make mistakes in computing the ‘non-inertial’connection (27,28)by hand,we used for checking its correctness the EXCALC package on exterior differential forms of the computer algebra system REDUCE,see Puntigam et al.80and the literature given there.3.3.Dirac matter waves in a non-inertial frame of referenceThe phase shift (24)can be derived from the Schr¨o dinger equation with a Hamilton operator for a point particle in an external Newton potential.For setting up a grav-itational theory,however,one better starts more generally in the special relativistic domain.Thus we have to begin with the Dirac equation in an external gravitational field or,if we expect the equivalence principle to be valid,with the Dirac equation in an accelerated and rotating,that is,in a non-inertial frame of reference.Take the Minkowski spacetime of SR.Specify Cartesian coordinates.Then the field equation for a massive fermion of spin1/2is represented by the Dirac equationi¯hγi∂iψ∗=mcψ,(29) where the Dirac matricesγi fulfill the relationγiγj+γjγi=2o ij.(30) For the conventions and the representation of theγ’s,we essentially follow Bjorken-Drell7.Now we straightforwardly transform this equation from an inertial to an accel-erated and rotating frame.By analogy with the equation of motion in an arbitrary frame as well as from gauge theory,we can infer the result of this transformation:In the non-inertial frame,the partial derivative in the Dirac equation is simply replaced by the covariant derivativei∂i⇒Dα:=∂α+i previously;we drop the bar for convenience).The anholonomic Dirac matrices are defined byγα:=e iαγi⇒γαγβ+γβγα=2oαβ.(32) The six matricesσβγare the infinitesimal generators of the Lorentz group and fulfill the commutation relation[γα,σβγ]=2i(oαβγγ−oαγγβ).(33) For Dirac spinors,the Lorentz generators can be represented byσβγ:=(i/2)(γβγγ−γγγβ),(34) furthermore,α:=γˆ0γwithγ={γΞ}.(35) Then,the Dirac equation,formulated in the orthonormal frame of the accelerated and rotating observer,readsi¯hγαDαψ=mcψ.(36) Although there appears now a‘minimal coupling’to the connection,which is caused by the change of frame,there is no new physical concept involved in this equation. Only for the measuring devices in the non-inertial frame we have to assume hypotheses similar to the clock hypothesis.This proviso can always be met by a suitable con-struction and selection of the devices.Since we are still in SR,torsion and curvatureof spacetime both remain zero.Thus(36)is just a reformulation of the‘Cartesian’Dirac equation(29).The rewriting in terms of the covariant derivative provides us with a rather ele-gant way of explicitly calculating the Dirac equation in the non-inertial frame of an accelerated,rotating observer:Using the anholonomic connection components of(28) as well asα=−i{σˆ0Ξ},wefind for the covariant derivative:Dˆ0=12c2a·α−ii∂2¯hσ=x×p+1∂t=Hψwith H=βmc2+O+E.(39)After substituting the covariant derivatives,the operators O and E,which are odd and even with respect toβ,read,respectively30:O:=cα·p+12m p2−β2m p·a·x4mc2σ·a×p+O(1Table2.Inertial effects for a massive fermion of spin1/2in non-relativistic approximation.Redshift(Bonse-Wroblewski→COW)Sagnac type effect(Heer-Werner et al.)Spin-rotation effect(Mashhoon)Redshift effect of kinetic energyNew inertial spin-orbit couplingd These considerations can be generalized to a Riemannian spacetime,see Huang34and the literature quoted there.。

2013英语职称考试押题卷阅读翻译2(理工A)_天一
Fermi Problem在七月的一个星期一的早上,在新墨西哥沙漠世界上第一颗原子弹爆炸了。
40秒后,振动波到达了意大利裔美国物理学家Enrico Fermi和他的团队的营地。
经过计算后,Fermi向他的团队宣布,这次爆炸的威力相当于1万吨炸药。
团队的人都很激动,但对这一结果都不惊奇。
Fermi的才智在科学界是众所周知的,1938年他就获得了诺贝尔奖。
4年后,他第一个发现了核链锁反应,把我们带入了核时代。
自从Fermi于1954年去世后,没有那个科学家既是一位精通的实验主义者又是一位领先的理论家。
与所有大师一样,Fermi有自己独特的风格。
他喜欢用最直接的方式找到问题的答案,并非常善于将复杂问题分成若干容易解决的小问题。
这是一个技巧,我们可以应用在日常生活中。
为了让他的学生学习这个技巧方法,Fermi会给他们提出一种类型的问题,就是现在被称为的Fermi问题。
Fermi问题就是那种你一听上去好像不可能会得到答案,但你又能利用很少的知识得到答案的问题。
如果当你把问题分成一些小问题,不用借助任何专业人员或书籍,每个小问题都能得到回答时,那你离正确答案会越来越近。
假设你想在不查阅资料的情况下确定出地球的周长。
每个人都知道纽约与洛杉矶相距大约三千英里,而且时差为三个小时。
三小时是一天的八分之一,而地球自转一周用一天时间。
那么,地球周长是三千英里乘以八,也就是两万四千英里,这与真实的答案24902.45英里有一定的误差,但误差小于百分之四。
总之,Fermi处理日常问题方法的价值在于鼓励人们独立的发现和发明。
无论这个发现是否与计算原子弹威力那样重要,还是确定纽约和洛杉矶的相距距离那么小的发现,查阅答案或是让其他人发现答案,都会剥夺你拥有创造力时的快乐和骄傲,并且还会使你失去实验所带给你的自信。
因此,像Fermi问题那样解决个人困境的思维一旦成为习惯,就会使你的生活丰富多彩。
Touring the Antarctic Brings Danger1. 乘轮船去南极旅游呈上升趋势,今年春天和夏天,三万五千多名游客会去南极旅游。

网络课堂优点和缺点和改进措施英语作文
网络课堂优点和缺点和改进措施英语作文Advantages, Disadvantages and Improvement Measures of Online ClassesIntroductionThe emergence of online classes has revolutionized the traditional method of education, providing students with greater flexibility and convenience in their learning. However, there are both advantages and disadvantages to this form of education, along with some drawbacks that need to be addressed to ensure the effectiveness of online learning. In this essay, we will discuss the advantages and disadvantages of online classes, as well as propose some improvement measures to enhance the overall quality of online education.Advantages of Online Classes1. Flexibility: Online classes allow students to create their own study schedule and learn at their own pace, providing greater flexibility and convenience compared to traditional classroom settings.2. Accessibility: Online classes eliminate geographical barriers, allowing students from different parts of the world toaccess high-quality education without having to travel to a physical campus.3. Cost-effective: Online classes are often more affordable than traditional courses, as they eliminate the need for commuting, textbooks, and other expenses associated withon-campus education.4. Personalized learning: Online classes can be tailored to meet the individual needs and learning styles of students, providing a more personalized learning experience.Disadvantages of Online Classes1. Lack of social interaction: Online classes lack theface-to-face interaction that is often a critical component of the learning experience, leading to feelings of isolation and disconnection among students.2. Technology issues: Online classes are dependent on technology, and technical issues such as internet connectivity problems or software glitches can disrupt the learning process.3. Limited feedback: In online classes, students may receive less feedback from instructors compared to traditional classroom settings, which can hinder their understanding and progress.4. Self-discipline: Online classes require a high level ofself-discipline and motivation from students, as they must manage their own time effectively and stay on track with their coursework.Improvement Measures for Online Classes1. Integrate more interactive elements: To enhance student engagement and participation, online classes should include interactive elements such as live webinars, discussion forums, and group projects.2. Provide adequate support: Institutions offering online classes should ensure that students have access to academic advisors, tutors, and technical support to address any issues they may encounter during their study.3. Incorporate regular assessments: To monitor student progress and provide timely feedback, online classes should include regular assessments and assignments that allow instructors to gauge the understanding and performance of students.4. Promote communication: To address the lack of social interaction in online classes, instructors should encouragecommunication among students through group discussions, online forums, and virtual study groups.ConclusionWhile online classes offer numerous benefits, such as flexibility, accessibility, and cost-effectiveness, there are also challenges that need to be addressed to ensure the effectiveness of online learning. By implementing improvement measures such as integrating interactive elements, providing adequate support, incorporating regular assessments, and promoting communication, institutions can enhance the overall quality of online education and provide students with a rewarding learning experience.。

Lesson 11)The one I am thinking of particularly is entered by Gothicarched gateway of aged brick and stone .You pass from the heat and glare of a big, open square into a cool, dark cavern which extends as far as the eye can see, losing itself in the shadowy distance.此时此刻我要说的集市的入口是一座古老的砖石结构的哥特式拱门,年代非常久远。
当你穿过一个烈日暴晒的大型露天广场,然后走进一个凉爽、幽暗的洞穴。
这洞穴一直一直向前延伸,一眼望不到尽头,最终消失在远处的阴影里。
2)It is a point of honor with the customers not to let the shopkeeper guess what it is she really likes and want until the last moment. 对于顾客来说,至关重要的一点是,不到最后一刻是不能让店主猜到她心里究竟中意哪样东西、想买哪样东西的.3)The seller ,on the other hand ,makes a point of protesting that the price he is charging is depriving him of all profit, and that he is sacrificing this because of his personal regard for the customer. 而在店主那一方来说,则是竭尽全力的让顾客相信,他开出的价钱使他根本无利可图,而他之所以愿意这样做完全是出于本人对顾客的敬重。

The book’s yellowing pages contain beekeeping notes made between 1941and 1969 by the late Walter Coates of Kilworth; Leicestershire. He adds it to his growing pile of local journals; birdwatchers’ list and gardening diaries. “We’re uncovering about one major new record each month;” he says; “I still get surprised.” Around two centuries before Coates; Robert Marsham; a landowner from Norfolk in the east of England; began recording the life cycles of plants and animals on his estate- when the first wood anemones flowered; the dates on which the oaks burst into leaf and the rooks began nesting. Successive Marshams continued compiling these notes for 211 years.B Today; such records are being put to uses that their authors could not possibly have expected. These data sets; and others like them; are proving invaluable to ecologists interested in the timing of biological events; or phenology. By combining the records with climate data; researchers can reveal how; for example; changes in temperature affect the arrival of spring; allowing ecologists to make improved predictions about the impact of climate change. A small band of researchers is combing through hundreds of years of records taken by thousands of amateur naturalists. And more systematic projects have also started up; producing an overwhelming response. “The amount of interest is almost frightening;” says Sparks; a climate researcher at the Centre for Ecology and Hydrology in Monks Wood; Cambridgeshire.C Sparks first became aware of the army of “closet phenologists”; as he describes them; when a retiring colleague gave him the Marsham records. He now spends much of his time following leads from one historical data set to another. As news of his quest spreads; people tip him off to other historical records; and more amateur phenologists come out of their closets. The British devotion to recording and collecting makes his job easier- one man from Ken t sent him 30 years’ worth of kitchen calendars; on which he has noted the date that his neighbour’s magnolia tree flowered.D Other researchers have unearthed data from equally odd sources. Rafe Sagarin; an ecologist at Stanford University in California; recently studied records of a betting contest in which participants attempt to guess the exact time at which a specially erected wooden tripod will fall through the surface of a thawing river. The competition has taken place annually on the Tenana River in Alaska since 1917; and analysis of the results showed that the thaw now arrives five years earlier than it did when the contest began.E Overall; such records have helped to show that; compared with 20years ago; a raft of natural events now occur earlier across much of the northern hemisphere; from the opening of leaves to the return of birds from migration and the emergence of butterflies from hibernation. The data can also hint at how nature will change in the future. Together with models of climate chan ge; amateurs’ records could help guide conservation. Terry Root; an ecologist at the University of Michigan in Ann Arbor; has collected birdwatchers’ counts of wildfowl taken between 1955 and 1996 on seasonal ponds in the American Midwest and combined them with climate data and models of future warming. Her analysis shows that the increased droughts that the models predict could halve the breeding populations at the ponds. “The number of waterfowl in North America will most probably drop significantly with global warming;” she says.F But not all professionals are happy to use amateur data. “A lot of scientists won’t touch them; they say they’re too full of problems;” says Root. Because different observers can have different ideas of what constitutes; for ex ample; an open snowdrop. “The biggest concern with ad hoc observations is how carefully and systematically they were taken;” says Mark Schwartz of the University of Wisconsin; Milwaukee; who studies the interactions between plants and climate.” We need to know pretty precisely what a person’s been observing- if they just say ‘I note when the leaves came out’; it might not be that useful;” Measuring the onset of autumn can be particularly problem-atic because deciding when leaves change colour is a more subjective process than noting when they appear.G Overall; most phenologists are positive about the contribution that amateurs can make. “They get at the raw power of science: careful observation of the natural world;” says Sagarin. But the professionals also acknowledge the need for careful quality control. Root; for example; tries to gauge the quality of an amateur archive by interviewing its collector. “You always have to worry- things as trivial as vacations can affect measurement. I disregard a lot of rec ords because they’re not rigorous enough;” she says. Others suggest that the right statistics can iron out some of the problems with amateur data. Together with colleagues at Wageningen University in the Netherlands; environmental scientist Arnold van Vliet is developing statistical techniques to account for the uncertainty in amateur phenological data. With the enthusiasm of amateur phenologists evident from past records; professional researchers are now trying to create standardized recording schemes for future efforts. They hope that well-designed studies will generate a volume of observations large enough to drown out the idiosyncrasies of individual recorders. The data are cheap to collect; and can provide breadth in space; time and range of species. “It’s very difficult to collect data on a large geographical scale without enlisting an army of observers;” says Root.H Phenology also helps to drive home messages about climate change. “Because the public understand these records; they accept them;” says S parks. It can also illustrate potentially un pleasant consequences; he adds; such as the finding that more rat infestations are reported to local councils in warmer years. And getting people involved is great for public relations. “People are thrilled to think that the data they’ve been collecting as a hobby can be used for something scientific –it empowers them;”says Root.Questions 27-33Reading Passage 3 has eight paragraphs A-HWhich paragraph contains the following informationWrite the correct letter A-H in boxes 27-33 on your answer sheet.27.

Hippocrates believed there were four different body fluids that influenced four basic types of temperament. His work was further developed 500 years later by Galen 130-200 A.D. These days there are any number of self-assessment tools that relate to the basic descriptions developed by Galen; although we no longer believe the source to be the types of body fluid that dominate our systems.Section BThe value in self-assessments that help determine personality style; learning styles; communication styles; conflict-handling styles; or other aspects of individuals is that they help depersonalize conflict in interpersonal relationships.The depersonalization occurs when you realize that others aren’t trying to be difficult; but they need different or more information than you do. They’re not intending to be rude; they are so focused on the task they forget about greeting people. They would like to work faster but not at the risk of damaging the relationships needed to get the job done. They understand there is a job to do; but it can only be done right with the appropriate information; which takes time to collect.When used appropriately; understanding communication styles can help resolve conflict on teams. Very rarely are conflicts true personality issues. Usually they are issues of style; information needs; or focus.Section CHippocrates and later Galen determined there were four basic temperaments: sanguine; phlegmatic; melancholic and choleric. These descriptions were developed centuries ago and are still somewhat apt; although you could update the wording. In today’s world; they translate into the four fairly common communication styles described below:Section DThe sanguine person would be the expressive or spirited style of communication. These people speak in pictures. They invest a lot of emotion and energy in their communication an often speak quickly; putting their whole body into it. They are easily sidetracked onto a story that may or may not illustrate the point they are tryingto make. Because of their enthusiasm they are great team motivators. They are concerned about people and relationships. Their high levels of energy can come on strong at times and their focus is usually on the bigger picture; which means they sometimes miss the details or the proper order of things. These people find conflict or differences of opinion invigorating and love to engage in a spirited discussion. They love change and are constantly looking for new and exciting adventures.Section EThe phlegmatic person-cool and persevering-translates into the technical or systematic communication style. This style of communication is focused on facts and technical details. Phlegmatic people have an orderly; methodical way of approaching tasks; and their focus is very much on the task; not on the people; emotions; or concerns that the task may evoke. The focus is also more on the details necessary to accomplish a task. Sometimes the details overwhelm the big picture and focus needs to be brought back to the context of the task. People with this style think the facts should speak for themselves; and they are not as comfortable with conflict. They need time to adapt to change and need to understand both the logic of it and the steps involved.Section FThe melancholic person who is softhearted and oriented toward doing things for others translates into the considerate or sympathetic communication style. A person with this communication style is focused on people and relationships. They are good listeners and do things for other people-sometimes to the detriment of getting things done for themselves. They want to solicit everyone’s opinion and make sure everyone is comfortable with whatever is required to get the job done. At times this focus on others can distract from the task at hand. Because they are so concerned with the needs for others and smoothing over issues; they do not like conflict. They believe that change threatens the status quo and tends to make people feel uneasy; so people with this communication style; like phlegmatic people; need time to consider the changes in order to adapt to them.Section GThe choleric temperament translates into the bold or direct style of communication. People with this style are brief in their communication-the fewer words the better. They are big picture thinkers and love to be involved in many things at once. They are focused on tasks and outcomes and often forget that the people involved in carrying out the tasks have n eeds. They don’t do detail work easily and as a result can often underestimate how much time it takes to achieve the task. Because they are so direct; they often seem forceful and can be very intimidating to others. They usually would welcome someone challenging them; but most other styles are afraid to do so. They also thrive on change; the more the better.Section HA well-functioning team should have all of these communication styles for true effectiveness. All teams need to focus on the task; and they need to take care of relationships in order to achieve those tasks. They need the big picture perspective or the context of their work; and they need the details to be identified and taken care offor success.We all have aspects of each style within us. Some of us can easily move from one style to another and adapt our style to the needs of the situation at hand – whether the focus is on tasks or relationships. For others; a dominant style is very evident; and it is more challenging to see the situation from the perspective of another style.The work environment can influence communication styles either by the type of work that is required or by the predominance of one style reflected in that environment. Some people use one style at work and another at home.The good news about communication styles is that we all have the ability to develop flexibility in our styles. The greater the flexibility we have; the more skilled we usually are at handling possible and actual conflicts. Usually it has to be relevant to us to do so; either because we think it is important or because there are incentives in our environment to encourage it. The key is that we have to want to become flexible with our communication style.

Humans may have a thing or two to learn from them.For the past decade Dr Engel; a lecture in environmental sciences at Britain’s Open University; has been collating examples of self-medicating behavior in wild animals. She recently published a book on the subject. In a talk at the Edinburgh science Festival earlier this month; she explained that the idea that animals can treat themselves has been regarded with some skepticism by her colleagues in the past. But a growing number of animal behaviourists now think that wild animals can and do deal with their own medical needs.One example of self-medication was discovered in 1987. Michael Huffman and Mohamedi Seifu; working in the Mahale Mountains National Park in Tanzania; noticed that local chimpanzees suffering from intestinal worms would dose themselves with pith of a plant called Veronia. This plant produces poisonous chemicals called terpenes. Its pith contains a strong enough concentration to kill gut parasites; but not so strong as to kill chimpsnor people; for that matter; locals use the pith for the same purpose.Given that the plant is kno wn locally as “goat-killer”; however; it seems that not all animals are as smart as chimps and humans. Some consume it indiscriminately; and succumb.Since the Veronia-eating chimps were discovered; more evidence has emerged suggesting that animals often eat things for medical rather than nutritional reasons. Many species; for example; consume dirt- a behavior known as geophagy. Historically; the preferred explanation was that soil supplies minerals such as salt. Butgeophagy occurs in areas where the earth is not a useful source of minerals; and also in places where minerals can be more easily obtained from certain plants that are known to be rich in them. Clearly; the animals must be getting something else out of eating earth.The current belief is that soil-and particularly the clay in it-helps to detoxify the defensive posions that some plants produce in an attempt to prevent themselves from being eaten. Evidence for the detoxifying nature of clay came in 1999; from an experiment carried out on macaws by James Gilardi and his colleagues at the University of California; Davis; Macaws eat seeds containing alkaloids; a group of chemicals that has some notoriously toxic members such as strychnine. In the wild; the birds are frequently seen perched on eroding riverbanks eating clay. Dr Gillardi fed one group of macaws a mixture of a harmless alkaloid and clay; and a second group just the alkaloid. Several hours later; the macaws that had eaten the clay had 60% less alkaloid in their blood streams than those that had not; suggesting that the hypothesis is correct.Other observations also support the idea that clays is detoxifying. Towards the tropics the amount toxic compounds in plants increases-and so does the amount of earth eaten by herbivores. Elephants lick clay from mud holes all year around; except in September when they are bingeing on fruit which; because it has evolved to be eaten; is not toxic. And the addition of clay to the diets of domestic cattle increases the amount of nutrients that they can absorb from their food by 10-20%.A third instance of animal self-medications is the use of mechanical scours to get rid of gut parasites. In 1972 Richard Wrangham; a researcher at the Gombe Stream Reserve in Tanzania; noticed that chimpanzees were eating the leaves of a tree called Aspilla. The chimps chose the leaves carefully by testing them in their mouths. Having chosen a leaf; a chimp would fold it into a fan and swallow it. Some of the chimps were noticed wrinkling their noses as they swallowed these leaves; suggesting the experience was unpleasant. Later; undigested leaves were found on the forest floor.Dr Wrangham rightly guessed that the leaves had a medicinal purpose-this was; indeed; one of the earliest interpretations of a behavior pattern as self-medication. However; he guessed wrong about what the mechanism was. Hisand everybody else’s assumption was that Aspilla contained a drug; and his sparked more than two decades of phytochemical research to try to find out what chemical the chimps were after. But by the 1990s; chimps across Africa had been seen swallowing the leaves of 19 different species that seemed to have few suitable chemicals in common. The drug hypothesis was looking more and more dubious.It was Dr Huffman who got to the bottom of the problem. He did so by watching what came out of the chimps; rather than concentrating on what went in. He found that the egested leaves were full of intestinal worms. The factor common to all 19 species of leaves swallowed by the chimps was that they were covered with microscopic hooks. These caught the worms and dragged them form their lodgings.Following that observation; Dr Engel is now particularly excited about how knowledge of the way that animals look after themselves could be used t to improvethe health of live-stock. People might also be able to learn a thing or two-and may; indeed; already have done so. Geophagy. For example; is a common behavior in many parts of the world. The medical stalls in African markets frequently sell tablets made of different sorts of clays; appropriate to different medical conditions. Africans brought to the Americas as slaves continued this tradition; which gave their owners one more excuse to affect to despise them. Yet; as Dr Engel points out; Rwandan mountain gorillas eat a type of clay rather similar to kaolinite-the main ingredient of many patent medicines sold over the counter in the west for digestive complaints. Dirt can sometimes be good for you; and to be “as sick as a parrot” may; after all; be a state to be desired.Questions 1-4Do the following statements agree with the information given in Reading Passage 1In boxes 1-4 on your answer sheet; writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this1.Dr. Engel has been working on animal self-medication research for 10 years.2.Animals often walk a considerable distance to find plants medication.3.Birds; like Macaw; often eat clay because it is part of their natural diet.4.According to Dr. Engel; research into animal self-medication can help to inventnew painkillers.Questions 5-9Complete the notes below using NO MORE THAN ONE WORD OR NUMBER from passage.Complete the summary below using words from the box.Write your answers; A-H; in boxes 10-13 on your answer sheet.Though often doubted; the self-medicating behavior of animals has been supported by an increasing amount of evidence.

Or in Charlie Paton’s case; out of the rain. “ I was in a bus in Morocco travelling through the desert;” he remembers. “It had been raining and the bus was full of hot; wet people. The windows steamed up and I went to sleep with a towel against the glass. When I woke; the thing was soaking wet.I had to wring it out. And it set me thinking. Why was it so wet ”The answer; of course; was condensation. Back home in London; a physicist friend; Philip Davies; explained that the glass; chilled by the rain outside; had cooled the hot humid air inside the bus below its dew point; causing droplets of water to form on the inside of the window. Intrigued; Paton-a lighting engineer by profession-started rigging up his own equipment. “I made my own solar stills. It occurred to me that you might be able to produce water in this way in the desert; simply by cooling the air. I wondered whether you could make enough to irrigate fields and grow crops.”Today; a decade on; his dream has taken shape as giant greenhouse on a desert island off Abu Dhabi in the Persian Gulf ---the first commercially viable Version of his “seawater greenhouse”. Local scientists; working with Paton under a license from his company Light Works; are watering the desert and growing vegetables in what is basically a giant dew-making machine that produces fresh water and cool air from sum and seawater. In awarding Paton first prize in a design competition two years ago; Marco Goldschmied; president of the Royal Institute of British Architects; called it “a truly original idea which has the potential to impact on the lives of millions of people living in coastal water-starved areas around the world.”The design has three main parts see Graphic. The greenhouse faces into the prevailing wind so that hot; dry desert air blows in through the front wall of perforated cardboard; kept wet and cool by a constant tickle of seawater pumped up from the nearby shoreline. The evaporating seawater cools and moistens the air. Last June; for example; when the temperature outside the Abu Dhabi greenhouse was 46°c; it was in the low 30s inside. While the air outside was dry; the humidity in the greenhouse was 90 percent. The cool; moist air allows the plants to grow faster; and because much less water evaporates from the leaves their demand for moisture drops dramatically. Paton’s crops thrived on a single litre of water p er square metre per day; compared to。
体验营销:洞察消费者的消费心理外文文献翻译
文献出处:Adeosun L P K, Ganiyu R A. Experiential Marketing: An Insight into the Mind of the Consumer[J]. Asian Journal of Business and Management Sciences, 2012, 2(7): 21-26.原文Experiential Marketing: An Insight into the Mind of the ConsumerLadipo Patrick Kunle Adeosun,Rahim Ajao Ganiyu ABSTRACTExperiential Marketing is the process of engaging customers with in-depth experiences of the product or a brand. It can also be termed as a live marketing engagement where there is a face to face interaction between the consumer and a product or a brand. Its purpose is to appeal to the emotional senses of the customers and to influence their choice decision. This paper aims at investigating consumer's response to retail experiential marketing. As a descriptive and explanatory study, it establishes a connection between consumer lifestyle and behavior in modern retailing and how it affects customer satisfaction. The paper suggests various characteristics and specifications that a retail outlet should have in order to appear most appealing to the consumer and create an experimental touch in the entire retailing process. Keywords:Shopping experience, customer, experiential marketing, customer satisfaction, emotional attachment.1 INTRODUCTIONIn recent years, there has been increased interest in building and enhancing customer experience among researchers and practitioners. Companies are shifting their attention and efforts from premium prices or superior quality to memorable experiences. Also, the value created by memorable or unique customer experiences and emotions exert significant impact on organizational performance in terms of customer satisfaction, retention and loyalty. Experiential marketing is the new approach which views marketing as an experience and treats consumption like a total experiment, by taking cognizance of the rational and emotional aspects ofconsumption using eclectic methods.We are in the era of …experience economy‟ and the main concern and preoccupation of proactive organization is how to create total experience and unique value system for customers, which necessitate the need to understand the life of customer from perspective of their shopping experience. Experiences is inherent in the mind of everyone, and may result into physical, emotional, and cognitive activities which invariably may generate strong feelings that the customer might take away. Experience tends to come from the interaction of personal minds and events, and thus no two experiences may be the same in any occasion (Schmitt, 1999).Schmitt (2003) distinguishes between five types of experience that marketers can create for customers to include; sensory experience (sense), affective experience (feel), creative cognitive experience (think), physical experience, behaviors and lifestyles (act), and social-identity experience, all relating to a reference group or culture (relate). The author posits that the ultimate goal of experiential marketing is to create holistic experience that seek to integrate all these individual types of experiences into total customer experience.According to Pine and Gilmore (1999), economic development is generating a new and dynamic era of experiences, which challenge the traditional sales approach focusing on product sales and service offering. And in order to enhance consumers' emotional connections to the brand and provide a point of differentiation in a competitive oligopoly, retailers have turned their attention to creating memorable retail experiences, which try to appeal to consumers at both physical as well as psychological levels.The emergence and spread of shopping malls, supermarkets and hypermarkets in both developed and developing countries, heightened competition for consumers‟ spendable or discretionary incomes. There are therefore more choices available for consumers than ever before. In such a situation retailers seeks to develop business strategies that focus on creating and maintaining customers, by offering customers a differentiated shopping experience.The term "Experiential Marketing" refers to actual customer experience with theproduct/service that drive sales and increase brand image and awareness. When done right, it's the most powerful technique to win brand loyalty. Olorunniwo et al., (2006) concluded that customer experience is related to behavioral intentions and connecting the audience with the authentic nature of the brand is one of the prime goal of experiential marketing. This is achieved through participation in personally relevant, credible and memorable encounters.Shopping has been considered a search process where shoppers would like to ensure that they make the right decisions. In addition, they also intend to derive emotional satisfaction (Tauber, 1972). It has been found that a high level of brand awareness may not translate into sales. Proactive organization should consider every visit of the shopper as a distinct encounter and a moment of truth. Unless the interaction is satisfactory, the next visit may not guaranteed. Therefore, if the store does not provide a compelling reason for a repeat patronage, the amount of purchase per visit may likely decline (Zeithaml, 1998).The growing significance of experiential marketing has resulted into diverse and fascinating study on the concept (e.g. Csikzentmihalyi, 1997; Schmitt 1999; Pine and Gilmore 1999; Holbrook, 2000; Arnould et al., 2002; Caru and Cova, 2003 to mention a few). However, the dynamics of consumer behavior have necessitated the need for more papers. With few exceptions, the existing experiential retail literature has focused mainly on the isolated testing of static design elements (i.e. atmospherics, ambient conditions, and services cape architecture) of retail stores (Turley and Milliman, 2000). McCole (2004) in particular recognizes this dearth of academic research in the areas of experiential and event marketing as an indication of the division between academia and business and calls for marketing theory in these areas to be more closely aligned with practice.Similarly, Gupta, (2003) identified a lack of systemic body of knowledge and conceptual framework on which to base scientific inquiry as a key tenet of experiential marketing. The current study seeks to address some of these gaps in the literature. In consequence this paper aims to gauge consumers' responses to experiential marketing in modern retail outlets and analyze the effect of experientialmarketing on consumer behavior.2. CONCEPTUAL BACKGROUNDExperience as defined within the realm of management is a personal occurrence with emotional significance created by an interaction with product or brand related stimuli (Holbrook and Hirschman, 1982). For this to become experiential marketing the result must be “something extremely significant and unforgettable for the consumer immersed in the experience” (Car u and Cova, 2003, p. 273). According to Schmitt (1999) experiential marketing is how to get customers to sense, feel, think, act, and relate with the company and brands. Customer satisfaction is a key outcome of experiential marketing and is defined as the “customer fulfillment response” which is an evaluation as well as an emotion-based response to a service. It is an indication of the customer‟s belief on the probability or possibility of a service leading to a positive feeling. And positive affect is positively and negatively related to satisfaction.Experiential marketing involves the marketing of a product or service through experience and in the process the customer becomes emotionally involved and connected with the object of the experience (Marthurs, 1971). A well designed experience engages the attention and emotion of the consumer, and becomes memorable and allows for a free interpretation, as it is non-partisan (Hoch, 2002). In contrast to traditional marketing which focuses on gaining customer satisfaction, experiential marketing creates emotional attachment for the consumers (McCole, 2004). The sensory or emotional element of a total experience has a greater impact on shaping consumer preferences than the product or service attributes Zaltman (2003). The benefits of a positive experience include the value it provides the consumer (Babin et al., 1994; Holbrook, 1999) and the potential for building customer loyalty.Experiential retail strategies facilitate the creation of emotional attachments, which help customers obtain a higher degree of possessive control over in-store activities (Schmitt, 2003). These strategies allow consumers to become immersed within the holistic experience design, which often creates a flow of experiences. Affective reaction based on an interaction with an object can be described as a person‟s subjective perception or judgment about whether such interaction willchange his or her core affect or his or her emotion toward the object. Cognitive reaction toward interacting with the object involves cognitive reasoning or appraisal, and is a consumer assessment of the purchase implications for his/her well being. Cognitive and affective reactions towards an object can be quite different, for example: one might appraise taking garlic as good and useful for one‟s health, nevertheless, one can at the same time consider it unpleasant due to its smell and taste.Experiential events can turn out to create both consumer and consumption experiences and can by far more effective in attaining communication goals. Caru and Cova (2003) conceptualization of experience, and Csikzentmihalyi (1997) experience typology and 7 …I‟s of Wood and Masterman (2007) may serve as a useful framework for evaluating the effectiveness of an event by developing measures that relates to the level of challenges, newness, surprise, and matching it with the audience‟s prior experience and skill level. However, the usefulness of measuring these attributes of the event depends upon the assumption and belief that an event that is strong in those attributes will effectively create a memorable and potentially behavior changing experience.The strategic experiential marketing framework consists of five strategic experiential models which create different forms of experience for customers. The five bases of the strategic experiential modules are: (1) Sensory experience: the sensory experience of customers towards experiential media includes visual, auditory, olfactory and tactile response results. (2) Emotional experience: the inner emotion and sense of customers raised by experience media. (3) Thinking experience: customers' thoughts on the surprise and enlightenment provoked by experience media. (4) Action experience: is the avenue through which experience media, linked customers so that they can acquire social identity and sense of belonging. (5) Related experience for customers: is actualizes through the experience of media production links, and to social recognition.3 METHODOLOGY AND METHODSThis study, being descriptive and explanatory, utilized secondary sources of information. Secondary information is a good source of data collection anddocumentation that cannot be under-estimated as it provides necessary background and much needed context which makes re-use a more worthwhile and systemic endeavour (Bishop, 2007).4. DISCUSSION AND CONCLUSIONSThe retailing business is constantly changing and experiencing huge trends due to changing consumer tastes, consumption patterns and buying behaviors. As a result of the changing con sumer shopping ecosystem, retailers‟ ability to sell its merchandise, depends largely on the strength of its marketing mix elements and ability to create a rewarding and fulfilling experiences for customers.Traditional marketing strategies focusing on price or quality are no longer a source of differentiation and competitive advantage. Researchers advocate that one of the main routes to successful differentiation and competitive advantage is a much stronger focus on the customer (Peppers and Rogers, 2004). Shopping involves a sequence of '‟see–touch–feel–select'‟ and the degree to which a shopper follows the whole or part of this process varies with brand, product category, and other elements of the marketing mix.Experiential marketing evolved as the dominant marketing tool of the future (McNickel, 2004). Companies have moved away from traditional “features and benefits” marketing, towards creating experiences for their customers (Williams, 2006). Experiential marketing has evolved as a response to a perceived transition from a service economy to one personified by the experiences, for instance, Williams (2006, p.484) argues that “modern economies are seen as making a transition from the marketing of services to the marketing of experiences, all tourism and hospitality offers acts of …theatre‟ that stage these experiences”.From now on leading edge companies, whether they sell to consumers or businesses, will achieve sustainable competitive advantage by staging experiences which include personal relevance, novelty, surprise, learning and engagement (Schmitt, 1999; Poulsson and Kale (2000). Undoubtedly, consumers now desire experiences and, in order to fully capitalize on this, business must deliberately orchestrate and engage in offering memorable experiences that create value andultimately achieve customer loyalty.译文体验营销: 洞察消费者的消费心理帕特里克;拉希姆摘要体验营销是通过提供深入的对产品或品牌体验过程来吸引客户。

It provides a standardized framework to measure the progress and learning outcomes of individuals, allowing educators to gauge the effectiveness of their teaching methods and the students' comprehension of the material. Examinations can take various forms, ranging from written tests and oral presentations to practical demonstrations and project-based assessments.One of the primary purposes of examination is to ensure academicrigor and maintain educational standards. By subjecting students to a consistent set of evaluations, educational institutions can ensure that students are meeting the required benchmarks and acquiring the necessary knowledge and skills to progress in their academic pursuits. This not only benefits the students themselves but also serves the broader societal interests by producing well-informed and capable individuals who can contribute to the workforce and society at large.However, the role of examination in the educational system has been the subject of much debate. Critics argue that the overemphasis on examinations can lead to a narrow focus on test-taking skills rather than the development of critical thinking, problem-solving, and creativity – essential skills for success in the modern world. They contend that the high-stakes nature of examinations can create undue stress and anxiety among students, potentially undermining their overall well-being and learning experiences.Moreover, concerns have been raised about the fairness and accuracy of examination processes. Some argue that examinations may not accurately reflect the true abilities and potential of students, as they can be influenced by factors such as test-taking strategies, socioeconomic backgrounds, and individual learning styles. This raises questions about the validity and reliability of examination results, and whether they truly serve as a reliable measure of astudent's knowledge and capabilities.In response to these criticisms, educational institutions and policymakers have been exploring alternative assessment methods that aim to provide a more holistic and personalized evaluation of student learning. These approaches often incorporate a greater emphasis on continuous assessment, project-based learning, and the integration of technology-enabled tools to capture a more comprehensive understanding of a student's progress and development.One such approach is the implementation of formative assessments, which focus on providing ongoing feedback and opportunities for students to demonstrate their learning throughout the educational process, rather than relying solely on summative examinations at the end of a unit or course. This allows educators to identify areas of strength and weakness in real-time, enabling them to tailor their teaching strategies and provide targeted support to students as needed.Another emerging trend is the incorporation of alternative assessment methods, such as portfolios, presentations, and performance-based tasks, which allow students to showcase their skills and knowledge in more authentic and meaningful ways. These assessments often require students to apply their learning to real-world scenarios, fostering the development of critical thinking, problem-solving, and collaboration skills – competencies that are highly valued in the modern workforce.Furthermore, the integration of technology in the assessment process has opened up new possibilities for more personalized and adaptive evaluations. Digital platforms and tools can provide students with customized feedback, adaptive testing based on their performance, and opportunities for self-reflection and self-assessment – all of which can enhance the learning experience and empower students to take a more active role in their own academic development.While these alternative assessment approaches hold promise, it is important to acknowledge that the traditional examination system still plays a crucial role in the educational landscape. Examinations continue to serve as a reliable and standardized method of evaluating student learning, particularly in high-stakes situations such as college admissions, professional certifications, and national assessments. The challenge lies in striking a balance between the benefits of traditional examinations and the need for more diverse and personalized assessment methods.In conclusion, the examination process is a complex and multifaceted aspect of the educational system, with both proponents and criticsoffering valid perspectives. While examinations serve important purposes in maintaining academic rigor and evaluating student learning, the ongoing discussions and the emergence of alternative assessment approaches highlight the need for a more comprehensive and balanced approach to assessment. By embracing a diverse range of assessment methods, educational institutions can strive to create a learning environment that fosters the holistic development of students, preparing them for the challenges and opportunities of the 21st century.。

地震高中英语阅读理解Earthquakes: Unraveling the Mysteries of the Earth's Dynamic ForcesEarthquakes, the sudden and often violent shaking of the Earth's surface, have captivated the human imagination for centuries. These powerful natural phenomena have the ability to reshape the landscape, topple structures, and claim countless lives, leaving an indelible mark on the collective consciousness of humanity. As we delve into the intricate workings of earthquakes, we uncover a complex tapestry of scientific understanding that not only illuminates the forces that shape our planet but also highlights the ongoing efforts to mitigate the devastating impact of these events.At the heart of earthquake science lies the theory of plate tectonics, which revolutionized our understanding of the Earth's dynamic interior. This theory posits that the Earth's surface is composed of a series of massive plates, constantly in motion, driven by the convection of the planet's molten interior. The boundaries between these plates are the primary loci of seismic activity, as the relentless forces of compression, tension, and shear create immense stresses that are ultimately released in the form of earthquakes.When tectonic plates collide, one plate is typically forced beneath the other, a process known as subduction. This subduction zone is a hotbed of seismic activity, as the descending plate generates intense friction and pressure, triggering a series of earthquakes. The Pacific Ring of Fire, a region encircling the Pacific Ocean, is a prime example of this, with a high concentration of active volcanoes and frequent earthquake occurrences.Earthquakes, however, are not limited to plate boundaries; they can also occur within the interior of tectonic plates, often along pre-existing fault lines. These intraplate earthquakes can be equally devastating, as evidenced by the 2011 Tohoku earthquake in Japan, which triggered a devastating tsunami and caused widespread destruction.The magnitude of an earthquake, a measure of the energy released during the event, is a crucial factor in determining its potential for destruction. The Richter scale, developed in the 1930s by American seismologist Charles Richter, provides a logarithmic scale for measuring earthquake magnitude, with each unit increase representing a tenfold increase in the amount of energy released. The most powerful earthquakes, often referred to as "megaquakes," can reach magnitudes exceeding 9.0 on the Richter scale, releasing staggering amounts of energy and causing catastrophic damage.While the raw power of earthquakes is awe-inspiring, the true tragedy lies in the human cost of these events. Densely populated urban centers, often built atop vulnerable geological structures, bear the brunt of the destruction, with buildings collapsing, infrastructure crumbling, and lives lost. The 2010 Haiti earthquake, for instance, claimed over 300,000 lives and left countless more injured or displaced, highlighting the devastating impact of these natural disasters on vulnerable communities.In the face of such immense challenges, the scientific community has dedicated itself to understanding the complex mechanisms that drive earthquakes, with the ultimate goal of improving our ability to predict and mitigate their consequences. Advancements in seismic monitoring technology, the development of early warning systems, and the implementation of stringent building codes have all played a crucial role in reducing the loss of life and property during earthquakes.Yet, the unpredictable nature of these events remains a formidable challenge. Earthquake prediction, long the Holy Grail of seismology, has proven to be an elusive goal, as the complex interplay of factors that trigger seismic events continues to defy our best efforts at forecasting. Nonetheless, scientists remain undaunted, leveraging the power of data analysis, computational modeling, and interdisciplinary collaboration to unravel the mysteries of the Earth'sdynamic forces.Beyond the scientific realm, the impact of earthquakes has also shaped the cultural and societal landscape of affected regions. The resilience and adaptability of communities in the face of such adversity have inspired awe and admiration, as people come together to rebuild and recover in the aftermath of these events. The lessons learned from past earthquakes have informed urban planning, emergency response protocols, and disaster management strategies, ensuring that we are better prepared to face the challenges that lie ahead.As we continue to grapple with the realities of a changing climate and the increasing frequency and intensity of natural disasters, the study of earthquakes assumes an even greater importance. By understanding the complex interplay of tectonic forces, we can develop more effective strategies for mitigating the impact of these events, protecting vulnerable populations, and ensuring the long-term resilience of our communities.In the end, the story of earthquakes is one of both humility and resilience. It reminds us of the raw power of nature and the fragility of our human constructs, but it also inspires us to push the boundaries of scientific understanding, to innovate, and to work together in the face of adversity. As we continue to unravel themysteries of the Earth's dynamic forces, we are reminded of our place in the grand tapestry of our planet, and the vital importance of our collective efforts to safeguard our future.。

Recently, the region continued its long tradition of expanding the limits of what is possible with a world record attemptnot on snow or ice, but on rails. To mark the 175th anniversary of Switzerland's first railway, a railway company created the world's longest passenger train—100 cars, 2, 990 tonnes and almost two kilometers long.Formed of 25 new electric trains, the recordbreaking 1, 906meter train took almost an hour to cover around 25 kilometers over the impressive UNESCO World Heritage Albula Line, which is famous for its endless swooping curves and steep inclines (斜坡). The mountain railways are regarded as great feats of engineering. The 62kilometer line be tween Thusis and St Moritz, a worldrenowned masterpiece of civil engineering, took just five years to build despite requiring 55 bridges and 39 tunnels.Unlike most Swiss and European railways, which use the standard gauge (标准轨距) between the rails of 1.435 meters, the rails, known as Rhaetische Bahn rails, are just one meter apart. “In order to complete the train's journey successfully, everything has to be perfect. We need to be 100% synchronized (同步的), every second. Everyone has to keep their speed and other systems under control at all times,” lead driver Andreas Kramer said. “We need to know the Albula Line very well, every change of gradient, and every incline.”The mountainous Swiss landscape has encouraged creative transportation solutions for generations, resulting in one of the most trainreliant nations in the world. On average, Swiss citizens travel about 2, 450 kilometers by train annuallyan estimated quarter of their total transportation system. In 2021, Swiss Federal Railways operated 11,260 trains carrying 880,000 passengers and 185,000 tonnes of goods per day on a 3, 265 kilometerlong network with 804 stations.

If you can answer this question,you already are accustomed to what we term “algospeak.” As more and more online users join social media platforms such as TikTok (抖音), algospeak continues to grow. But what is it, what do these words mean?Algospeak is a coded language or slang used online. For some communities it is the only way to talk safely about sensitive subjects. Due to the rise of algorithmic censorship (算法筛查) in media, algospeak developed as a way to prevent robot from deleting their videos and messages. Users had to get creative to avoid deletion. This means that as long as there is censorship, there will be a new language to avoid it.Further, new slang created on social media platforms fits itself into everyday life. Even if you are not writing a message on TikTok, you may have caught yourself using phrases from the app in your daily life. This connection between people all over the globe allows for shared vocabulary. It also has the potential to completely change the way we as English speakers speak. Here is some new slang popularized by TikTok.Bussin' (adj.)—something is really good, usually referring to foodMid (adj.)—ordinary, not good or badSheesh (ex.)—response either meaning disbelief or surprise, can be positive or negativeValid (adj.)—something very good or meets a very high standard; a respectable opinionNo one would have suspected artificial intelligence (AI) would be the catalyst (催化剂) for change but it is. The combination of not only censorship but also high connectivity birthed a new language. Some older generations can't even understand what the youngest generation says because of the lack of exposure to the new language. The gap between English before social media and English as it is now is giant, and it continues to grow.So, what should we expect for the future? Will censorship loosen or will the English language continue to evolve from digital media?

1. Introduction Yang-Mills theory provides the theoretical basis for all descriptions of high energy physics, yet we still know very little about the actual quantization of such a system. One of the biggest problems is that the very gauge invariance that makes the theory so attractive implies that not all components of the gauge field are physical. This is a familiar problem in electrodynamics where it is only the transverse components of the photon that have an independent physical significance. Based on this observation one can quantize electrodynamics after reducing it to the true degrees of freedom1 . The technical complication in Yang-Mills theory then being that there is no similar (or at least useful) classical reduction to the true degrees of freedom, and hence we are forced to quantize more than the physical content of the theory. Clearly, some method is then needed for extracting the physical sector from the extended quantum theory. A systematic approach to this type of problem was initiated by Dirac [1] and has become known as Dirac’s approach to the quantization of a constrained system. Working in a slightly more general context than the specific example of Yang-Mills theory (for the traditional quantization of Yang-Mills theory we refer to Ref. 2), consider a classical system given by an extended phase space with first class constraints, φi = 0 .

Abstract. It has been known for some time that there are many inequivalent quantizations possible when the configuration space of a system is a coset space G/H. Viewing this classical system as a constrained system on the group G, we show that these inequivalent quantizations can be recovered from a generalization of Dirac’s approach to the quantization of such a constrained system within which the classical first class constraints (generating the H-action on G) are allowed to become anomalous (second class) when quantizing. The resulting quantum theories are characterized by the emergence of a Yang-Mills connection, with quantized couplings, and new ‘spin’ degrees of freedom. Various applications of this procedure are presented in detail: including a new account of how spin can be described within a pathintegral formalism, and how on S 4 chiral spin degrees of freedom emerge, coupled to a BPST instanton.
Being first class simply means that under the Poisson bracket the constraints close, i.e.,
k φk , {φi , φj } = fij
(1.2)
k for some structure functions fij . In Yang-Mills theory it is Gauss’ law that plays the role
of the constraints and the structure functions are actually constants. The idea behind Dirac’s approach to the quantization of such a constrained system is to first quantize on the extended system, ignoring the constraints, then reduce to the physical states by imposing the conditions implementing the constraints (1.1) at the quantum level: φi |ψphy = 0 .

(1.3)
This is, of course, possible only if one is willing to give up the manifest Lorentz invariance of the quantum theory. If not, then even in electrodynamics one has to deal with an extended system in one way or another. 2

Fig. 1: Traditional point of view on reduction/quantization As long as the first class nature (1.2) of the constraints has been preserved (and modulo ordering problems if the structure functions are not constants), condition (1.3) is consistent and should result in a reasonable set of physical states. In fact, it is expected that this process will recover the same set of states arrived at by directly quantizing on the true degrees of freedom. So we can summarize Dirac’s approach to the quantization of a constrained system by the (commutative) diagramme in Fig. 1. This freedom of changing the ordering of quantizing and reducing is directly testable in electrodynamics and, although one can find toy models where curvature effects can spoil the commutivity of this description [3], more modern accounts which use ghost variables [4] show that we are able in general to recover the expected quantization on the reduced space from this type of constrained quantization on the extended system. But what is the expected quantization? Our expectations for what is the correct quantization on the reduced system is based, to a large extent, on our experience with quantizing simple quantum mechanical systems such as the harmonic oscillator or the Hydrogen atom — systems which have very simple configuration spaces Q of the form Rn , for some n. For electrodynamics the physical configuration space is essentially a linear space, so we are quite confident in our intuition for what is the expected quantum theory. But in Yang-Mills theory the physical configuration space Q is a very complicated space [5], having features more in common with the coset spaces of the form G/H, for some groups G and H, rather than Rn , for any n. 3
