本文详细介绍了罗素悖论的产生,作用,回答及由此发展的新理论。罗素悖论的提出基于一个非常有意思的理发师悖论。1903年,罗素悖论的发表从根本上揭示了费雷格集合系统的局限性。上世纪很多数学家都试图对这个悖论作出回答,但都失败了。罗素自己对这个悖论的回答促进了类型理论的形成,他指出,悖论的问题在于我们混淆了数集和数集的集合。所以,罗素介绍了对象的分级系统:数、数集、数集的集合等等。后来,策梅洛对于罗素悖论的解决方法用了新的公理,这就是现在数学家普遍接受的策梅洛-弗兰克尔集合论。

This paper introduces in detail the Russell paradox, role, and the development of new theory. Russell paradox based on a very interesting barber paradox. In 1903, Russell paradox published reveals radically Frege set the limitation of the system. The last century many mathematicians have attempted to answer this paradox, but failed. Russell himself to this paradox answer promoted type theory formation, he pointed out, the paradox problem we mix number set and number set. So, Russell describes the object classification system: the number, the number of sets, set etc.. Later, Zermelo for the Russell paradox solution using a new axiom, it is now generally accepted Zermelo - Fraenkel set theory.

暗能量的存在并未被证明,但却是宇宙学家最感兴趣、最迫切想了解的事物之一,它是科学家用来解释宇宙为何不断加速膨胀的最佳猜想。20世纪90年代中叶科学家在开始测算宇宙膨胀速度的时候发现了这种能加速宇宙膨胀的能量——暗能量,宇宙常数是它的理论基础。暗能量有时候会与同样神秘的暗物质相混淆,尽管它们两是不同的事物。暗物质是一种假想的物质,把两者加在一起,暗物质和暗能量似乎占据了宇宙的绝大部分质量。暗能量的发现还引起了一大堆其他的问题。

The existence of dark energy has not been proved, but it is one of the cosmologists are most interested in, most urgently want to know things, it is the best guess scientists use to explain why the Universe is constantly accelerating expansion. The mid-1990s, scientists found that the speed of expansion of the universe at the beginning of calculation this can be the energy of the accelerated expansion of the universe - dark energy, the cosmological constant is its theoretical basis. Dark energy can sometimes be confused with the equally mysterious dark matter, even though they are two different things. Dark matter is a hypothetical substance, the two are added together, the dark matter and dark energy seems to occupy most of the quality of the universe. The discovery of dark energy also caused a lot of other issues.

作为世界最流行的社交网站——脸谱,我怀疑它能否在此后的十年继续存在。脸谱使得个人隐私无处遁形,其流行提倡分享个人所有情况的理念,反而使泄露变为规范而隐私变得不合时宜。脸谱的成员还在不断增加,而且倾向于中年及以

上人群,其发展的速度令人吃惊。成员可以把任何一有意向的人定义为“朋友”,这样让为数不多的密友和许多非密友之间的区别变得模糊不清,区分私人和公共似乎无意义了。这也是脸谱最受争议的地方,其默认隐私设置的抗议声也很大,大卫.埃文斯和克里斯的观点最能说明这个问题了。总之,脸谱的隐私设置问题和对朋友界限的模糊是一种对正常理念的挑战。

As the world's most popular social networking site -- Facebook, I doubt whether it during the next ten years to continue to exist. Facebook makes the personal privacy nowhere to hide, the popular advocate the concept of sharing personal all situations, but leaked into normative and privacy become be inopportune or inappropriate. Facebook members are increasing, and tend to the middle-aged and older, its development rate surprise. Members can make any intention of the defined as " friends ", so that the number of close friends and a lot of friends distinction becomes blurred, the distinction between private and public seems pointless. It is also the most controversial place faces, its default privacy settings of protest is also great, David Evans and Chris's idea best illustration of this problem. In short, Facebook's privacy settings and on line fuzzy friend is a kind of normal concept challenges

UNIT4

人类拥有远程控制的代理机器人并不是梦想,在不久的将来就会实现。Anybots公司最新的代理机器人QB可以很好地说明这点。你可以把QB看做自己的一个虚拟拓展,允许他们参加会议、查看旅游设施或呈现房地产市场走势,所有这些都可依靠电脑键盘来操控机器人完成。即将在年底开始销售的QB机器人拥有500像素的摄像头充当眼睛,拥有自我平衡系统的双车轮,高度可以自由伸缩。QB远程操作的能力将能证明其15000美元的价格是合理的。QB的技术目前还不是十分稳定,经过多次测试发现的问题也说明了它的使用有局限性。

Humans have a remote control robot agent is not a dream, will come true in the near future. Anybots's new robot agent QB can be well described. You can think of QB as a virtual extension, to allow them to participate in the meeting, see tourist facilities or presents the trend of the real estate market, all of which rely on the computer keyboard to control the robot to complete the. Will begin at the end of the sales of QB robot with 500 pixel camera acts as the eyes, with self balancing system of dual wheels, height can be freely telescopic. QB remote operation capability will be able to demonstrate its $15000 price is reasonable. QB technology is not very stable, through a series of tests found problems and explains its application limitation.

基因工程看似复杂,其原理却是相对简单的。该技术的前提是基于遗传信息,由DNA编码和安排形成基因,基因克隆的本质是遗传操作,可以分为四个步骤:新一代的DNA片段、加入到向量或载体分子、引入到宿主细胞进行扩增、选择所需的序列。这些技术的发展依赖于微生物遗传学家提供的知识,其发展分为三个主要时期,1966年建立完整的遗传密码时达到顶峰。在60年代后期,研究发展受到技术的限制,进展缓慢。1972年斯坦福大学生成了世界第一个核酸分子并在1973年完成了突破性的实验,这就标志着众所周知的基因克隆技术的出现。

Gene engineering seems complicated, its principle is relatively simple. The technique is based on the premise of genetic information, encoded by DNA and arranged to form a gene, gene cloning is the nature of the genetic operation, can be divided into four steps: a new generation of DNA fragments, joined to a vector or a carrier molecule, introduced into the host cell amplification, select the desired sequence. The technology relies on the development of microbial geneticist provides knowledge, its development is divided into three main periods, in 1966 the establishment of the complete genetic code when they reach the top. In the late 60's, research development constrained
