第1课知识的悖论The Paradox of KnowledgeThe greatest achievement of humankind in its long evolution from ancient hominoid ancestors to its present status is the acquisition and accumulation of a vast body of knowledge about itself, the world, and the universe. The products of this knowledge are all those things that, in the aggregate, we call "civilization," including language, science, literature, art, all the physical mechanisms, instruments, and structures we use, and the physical infrastructures on which society relies. Most of us assume that in modern society knowledge of all kinds is continually increasing and the aggregation of new information into the corpus of our social or collective knowledge is steadily reducing the area of ignorance about ourselves, the world, and the universe. But continuing reminders of the numerous areas of our present ignorance invite a critical analysis of this assumption.In the popular view, intellectual evolution is similar to, although much more rapid than, somatic evolution. Biological evolution is often described by the statement that "ontogeny recapitulates phylogeny"--meaning that the individual embryo, in its development from a fertilized ovum into a human baby, passes through successive stages in which it resembles ancestral forms of the human species. The popular view is that humankind has progressed from a state of innocent ignorance, comparable to that of an infant, and gradually has acquired more and more knowledge, much as a child learns in passing through the several grades of the educational system. Implicit in this view is an assumption that phylogeny resembles ontogeny, so that there will ultimately be a stage in which the accumulation of knowledge is essentially complete, at least in specific fields, as if society had graduated with all the advanced degrees that signify mastery of important subjects.Such views have, in fact, been expressed by some eminent scientists. In 1894 the great American physicist Albert Michelson said in a talk at the University of Chicago:While it is never safe to affirm that the future of Physical Science has no marvels in store even more astonishing than those of the past, it seems probable that most of the grand underlying principles have been firmly established and that further advances are to be sought chiefly in the rigorous application of these principles to all the phenomena which come under our notice .... The future truths of Physical Science ate to be looked for in the sixth place of decimals.In the century since Michelson's talk, scientists have discovered much more than the refinement of measurements in the sixth decimal place, and none is willing to make a similar statement today. However, many still cling to the notion that such a state of knowledge remains a possibility to be attained sooner or later. Stephen Hawking, thegreat English scientist, in his immensely popular book A Brief History of Time (1988), concludes with the speculation that we may "discover a complete theory" that "would be the ultimate triumph of human reason--for then we would know the mind of God." Paul Davies, an Australian physicist, echoes that view by suggesting that the human mind may be able to grasp some of the secrets encompassed by the title of his book The Mind of God (1992). Other contemporary scientists write of "theories of everything," meaning theories that explain all observable physical phenomena, and Nobel Laureate Steven Weinberg, one of the founders of the current standard model of physical theory, writes of his Dreams of a Final Theory (1992).Despite the eminence and obvious yearning of these and many other contemporary scientists, there is nothing in the history of science to suggest that any addition of data or theories to the body of scientific knowledge will ever provide answers to all questions in any field. On the contrary, the history of science indicates that increasing knowledge brings awareness of new areas of ignorance and of new questions to be answered.Astronomy is the most ancient of the sciences, and its development is a model of other fields of knowledge. People have been observing the stars and other celestial bodies since the dawn of recorded history. As early as 3000 B.C. the Babylonians recognized a number of the constellations. In the sixth century B.C., Pythagoras proposed the notion of a spherical Earth and of a universe with objects in it chat moved in accordance with natural laws. Later Greek philosophers taught that the sky was a hollow globe surrounding the Earth, that it was supported on an axis running through the Earth, and chat stars were inlaid on its inner surface, which rotated westward daily. In the second century A.D., Ptolemy propounded a theory of a geocentric (Earth-centered) universe in which the sun, planets, and stars moved in circular orbits of cycles and epicycles around the Earth, although the Earth was not at the precise center of these orbits. While somewhat awkward, the Ptolemaic system could produce reasonably reliable predictions of planetary positions, which were, however, good for only a few years and which developed substantial discrepancies from actual observations over a long period of time. Nevertheless, since there was no evidence then apparent to astronomers that the Earth itself moves, the Ptolemaic system remained unchallenged for more than 13 centuries.In the sixteenth century Nocolaus Copernicus, who is said to have mastered all the knowledge of his day in mathematics, astronomy, medicine, and theology, became dissatisfied with the Ptolemaic system. He found that a heliocentric system was both mathematically possible and aesthetically more pleasing, and wrote a full exposition of his hypothesis, which was not published until 1543, shortly after his death. Early inthe seventeenth century, Johannes Kepler became imperial mathematician of the Holy Roman Empire upon the death of Tycho Brahe, and he acquired a collection of meticulous naked-eye observations of the positions of celestial bodies chat had been made by Brahe. On the basis of these data, Kepler calculated that both Ptolemy and Copernicus were in error in assuming chat planets traveled in circular orbits, and in 1609 he published a book demonstrating mathematically chat the planets travel around the sun in elliptical orbits. Kepler's laws of planetary motion are still regarded as basically valid.In the first decade of the seventeenth century Galileo Galilei learned of the invention of the telescope and began to build such instruments, becoming the first person to use a telescope for astronomical observations, and thus discovering craters on the moon, phases of Venus, and the satellites of Jupiter. His observations convinced him of the validity of the Copernican system and resulted in the well-known conflict between Galileo and church authorities. In January 1642 Galileo died, and in December of chat year Isaac Newton was born. Modern science derives largely from the work of these two men.Newton's contributions to science are numerous. He laid the foundations for modem physical optics, formulated the basic laws of motion and the law of universal gravitation, and devised the infinitesimal calculus. Newton's laws of motion and gravitation are still used for calculations of such matters as trajectories of spacecraft and satellites and orbits of planets. In 1846, relying on such calculations as a guide to observation, astronomers discovered the planet Neptune.While calculations based on Newton's laws are accurate, they are dismayingly complex when three or more bodies are involved. In 1915, Einstein announced his theory of general relativity, which led to a set of differential equations for planetary orbits identical to those based on Newtonian calculations, except for those relating to the planet Mercury. The elliptical orbit of Mercury rotates through the years, but so slowly that the change of position is less than one minute of arc each century. The equations of general relativity precisely accounted for this precession; Newtonian equations did not.Einstein's equations also explained the red shift in the light from distant stars and the deflection of starlight as it passed near the sun. However, Einstein assumed chat the universe was static, and, in order to permit a meaningful solution to the equations of relativity, in 1917 he added another term, called a "cosmological constant," to the equations. Although the existence and significance of a cosmological constant is still being debated, Einstein later declared chat this was a major mistake, as Edwin Hubble established in the 1920s chat the universe is expanding and galaxies are receding fromone another at a speed proportionate to their distance.Another important development in astronomy grew out of Newton's experimentation in optics, beginning with his demonstration chat sunlight could be broken up by a prism into a spectrum of different colors, which led to the science of spectroscopy. In the twentieth century, spectroscopy was applied to astronomy to gun information about the chemical and physical condition of celestial bodies chat was not disclosed by visual observation. In the 1920s, precise photographic photometry was introduced to astronomy and quantitative spectrochemical analysis became common. Also during the 1920s, scientists like Heisenberg, de Broglie, Schrodinger, and Dirac developed quantum mechanics, a branch of physics dealing with subatomic particles of matter and quanta of energy. Astronomers began to recognize that the properties of celestial bodies, including planets, could be well understood only in terms of physics, and the field began to be referred to as "astrophysics."These developments created an explosive expansion in our knowledge of astronomy. During the first five thousand years or more of observing the heavens, observation was confined to the narrow band of visible light. In the last half of this century astronomical observations have been made across the spectrum of electromagnetic radiation, including radio waves, infrared, ultraviolet, X-rays, and gamma rays, and from satellites beyond the atmosphere. It is no exaggeration to say chat since the end of World War II more astronomical data have been gathered than during all of the thousands of years of preceding human history.However, despite all improvements in instrumentation, increasing sophistication of analysis and calculation augmented by the massive power of computers, and the huge aggregation of data, or knowledge, we still cannot predict future movements of planets and other elements of even the solar system with a high degree of certainty. Ivars Peterson, a highly trained science writer and an editor of Science News, writes in his book Newton's Clock (1993) that a surprisingly subtle chaos pervades the solar system. He states:In one way or another the problem of the solar system's stability has fascinated and tormented asrtonomers and mathematicians for more than 200 years. Somewhat to the embarrassment of contemporary experts, it remains one of the most perplexing, unsolved issues in celestial mechanics. Each step toward resolving this and related questions has only exposed additional uncertainties and even deeper mysteries.Similar problems pervade astronomy. The two major theories of cosmology, general relativity and quantum mechanics, cannot be stated in the same mathematical language, and thus are inconsistent with one another, as the Ptolemaic and Copernicantheories were in the sixteenth century, although both contemporary theories continue to be used, but for different calculations. Oxford mathematician Roger Penrose, in The Emperors New Mind (1989), contends that this inconsistency requires a change in quantum theory to provide a new theory he calls "correct quantum gravity."Furthermore, the observations astronomers make with new technologies disclose a total mass in the universe that is less than about 10 percent of the total mass that mathematical calculations require the universe to contain on the basis of its observed rate of expansion. If the universe contains no more mass than we have been able to observe directly, then according to all current theories it should have expanded in the past, and be expanding now, much more rapidly than the rate actually observed. It is therefore believed that 90 percent or more of the mass in the universe is some sort of "dark matter" that has not yet been observed and the nature of which is unknown. Current theories favor either WIMPs (weakly interacting massive particles) or MACHOs (massive compact halo objects). Other similar mysteries abound and increase in number as our ability to observe improves.The progress of biological and life sciences has been similar to that of the physical sciences, except that it has occurred several centuries later. The theory of biological evolution first came to the attention of scientists with the publication of Darwin's Origin of Species in 1859. But Darwin lacked any explanation of the causes of variation and inheritance of characteristics. These were provided by Gregor Mendel, who laid the mathematical foundation of genetics with the publication of papers in 1865 and 1866.Medicine, according to Lewis Thomas, is the youngest science, having become truly scientific only in the 1930s. Recent and ongoing research has created uncertainty about even such basic concepts as when and how life begins and when death occurs, and we are spending billions in an attempt to learn how much it may be possible to know about human genetics. Modern medicine has demonstrably improved both our life expectancies and our health, and further improvements continue to be made as research progresses. But new questions arise even more rapidly than our research resources grow, as the host of problems related to the Human Genome Project illustrates.From even such an abbreviated and incomplete survey of science as this, it appears that increasing knowledge does not result in a commensurate decrease in ignorance, but, on the contrary, exposes new lacunae in our comprehension and confronts us with unforeseen questions disclosing areas of ignorance of which we were not previously aware.Thus the concept of science as an expanding body of knowledge that will eventually encompass or dispel all significant areas of ignorance is an illusion. Scientists and philosophers are now observing that it is naive to regard science as a process that begins with observations that are organized into theories and are then subsequently tested by experiments. The late Karl Popper, a leading philosopher of science, wrote in The Growth of Scientific Knowledge (1960) chat science starts from problems, not from observations, and chat every worthwhile new theory raises new problems. Thus there is no danger that science will come to an end because it has completed its task, clanks to the "infinity of our ignorance."At least since Thomas Kuhn published The Structure of Scientific Revolutions (1962), it has been generally recognized that observations are the result of theories (called paradigms by Kuhn and other philosophers), for without theories of relevance and irrelevance there would be no basis for determining what observations to make. Since no one can know everything, to be fully informed on any subject (a claim sometimes made by those in authority) is simply to reach a judgment that additional data are not important enough to be worth the trouble of securing or considering.To carry the analysis another step, it must be recognized that theories are the result of questions and questions are the product of perceived ignorance. Thus it is chat ignorance gives rise to inquiry chat produces knowledge, which, in turn, discloses new areas of ignorance. This is the paradox of knowledge: As knowledge increases so does ignorance, and ignorance may increase more than its related knowledge.My own metaphor to illustrate the relationship of knowledge and ignorance is based on a line from Matthew Arnold: "For we are here as on a darkling plain...." The dark chat surrounds us, chat, indeed, envelops our world, is ignorance. Knowledge is the illumination shed by whatever candles (or more technologically advanced light sources) we can provide. As we light more and more figurative candles, the area of illumination enlarges; but the area beyond illumination increases geometrically. We know chat there is much we don't know; but we cannot know how much there is chat we don't know. Thus knowledge is finite, but ignorance is infinite, and the finite cannot ever encompass the infinite.This is a revised version of an article originally published in COSMOS 1994.

知识分子与大众英语作文Intellectuals and the Public。
As an intellectual, I have often found myselfstruggling to communicate with the general public, especially when it comes to topics that are considered complex or specialized. While I believe that knowledge and expertise are important, I also recognize that there is a gap between intellectuals and the public that needs to be bridged.One of the main challenges that intellectuals face is the use of jargon and technical language that can be difficult for the average person to understand. This can create a sense of alienation and exclusion, which can lead to a lack of interest or engagement in the topic at hand. As intellectuals, we need to be more aware of the language we use and strive to communicate our ideas in a way that is accessible and relatable to the general public.Another challenge is the perception that intellectuals are elitist and out of touch with the realities of everyday life. This can be a difficult stereotype to overcome, butit is important for us to recognize that our knowledge and expertise can be used to benefit society as a whole. Weneed to be more proactive in engaging with the public and demonstrating the relevance of our work to their lives.At the same time, it is important for the public to recognize the value of intellectual pursuits and the contributions that intellectuals make to society. This requires a shift in mindset that recognizes the importanceof education and lifelong learning, and the role that intellectuals play in advancing knowledge and understanding.Ultimately, the relationship between intellectuals and the public is a two-way street. It requires both parties to be open-minded, curious, and willing to engage inmeaningful dialogue. By working together, we can bridge the gap between knowledge and understanding, and create a more informed and enlightened society.。

有关科学精神且有生活例子的英语作文
有关科学精神且有生活例子的英语作文Science is a way of understanding the world around us, a systematic approach to exploring the mysteries of the universe. It is a pursuit of knowledge that has transformed our lives in countless ways, from the technological marvels that surround us to the deeper insights we have gained into the fundamental nature of reality. At its core, the scientific spirit embodies a set of principles and attitudes that have the power to enrich our lives and shape our understanding of the world.One of the defining characteristics of the scientific spirit is a relentless curiosity and a desire to explore the unknown. Scientists are driven by a deep fascination with the natural world and a burning desire to uncover its secrets. They approach every problem with a sense of wonder, constantly questioning the status quo and seeking new ways to understand the phenomena that surround us.This spirit of inquiry is not limited to the laboratory or the academic realm; it can be applied to all aspects of our lives. Consider the case of a young child, for example, who looks at the world with wide-eyed wonder, constantly asking "why?" and "how?" as they try to make sense of their surroundings. This innate curiosity is the foundation ofthe scientific mindset, and it is a quality that we should strive to nurture and cultivate throughout our lives.Another key aspect of the scientific spirit is the commitment to empirical evidence and the rigorous testing of hypotheses. Scientists do not simply accept claims at face value; they demand proof, and they are willing to challenge and overturn long-held beliefs if the evidence points in a different direction. This commitment to objectivity and critical thinking is essential for the advancement of human knowledge, as it allows us to constantly refine and improve our understanding of the world.Consider, for example, the story of Galileo Galilei, the renowned Italian astronomer and physicist who challenged the prevailing belief that the Earth was the center of the universe. Galileo's observations through his telescope, which revealed the moons of Jupiter and the phases of Venus, provided compelling evidence that the Earth revolved around the Sun. Despite facing fierce opposition from the Catholic Church, Galileo remained steadfast in his commitment to the scientific method, and his work ultimately helped to usher in a new era of scientific understanding.The scientific spirit is also characterized by a willingness to embrace uncertainty and to acknowledge the limitations of our knowledge. Scientists understand that the pursuit of knowledge is an ongoingprocess, and that every new discovery often leads to more questions than answers. This humility in the face of the unknown is a critical aspect of the scientific mindset, as it allows us to remain open-minded and receptive to new ideas and perspectives.One powerful example of this humility can be found in the field of quantum mechanics, a branch of physics that has fundamentally challenged our understanding of the nature of reality. Quantum theory has revealed that the subatomic world operates according to a set of rules that are often counterintuitive and seemingly paradoxical. Yet, rather than dismissing these findings, physicists have embraced the uncertainty and have continued to explore the mysteries of the quantum realm, leading to groundbreaking advancements in our understanding of the universe.The scientific spirit is not just about the pursuit of knowledge; it is also about the application of that knowledge to improve the human condition. Scientists have played a crucial role in addressing some of the most pressing challenges facing our world, from developing life-saving medical treatments to finding ways to mitigate the impact of climate change. This commitment to using science for the betterment of humanity is a hallmark of the scientific spirit.Consider, for example, the story of Marie Curie, the pioneering physicist and chemist who, along with her husband Pierre,discovered the elements radium and polonium. Curie's groundbreaking work on radioactivity not only expanded our understanding of the physical world but also led to the development of medical treatments for cancer, a disease that had long been a scourge on humanity. Curie's dedication to using science to improve the lives of others is a testament to the power of the scientific spirit.In conclusion, the scientific spirit is a powerful force that has the potential to transform our lives and our understanding of the world. It is a mindset characterized by curiosity, critical thinking, humility, and a commitment to using knowledge for the betterment of humanity. By embracing the scientific spirit in our daily lives, we can become more curious, more open-minded, and more engaged with the world around us, ultimately leading to a deeper appreciation for the mysteries and wonders of the universe.。
我认为学习人文科学的是必要的英语作文
In today's world, where science and technology reign supreme, the importance of humanities education is often questioned or even overshadowed. However, I staunchly advocate that studying the humanities is not merely an option; it is a necessity for the holistic development of individuals and society at large. This essay will delve into multiple dimensions to argue why the pursuit of humanities is as crucial as any other scientific discipline.Firstly, the humanities cultivate empathy and ethical reasoning. They encompass disciplines such as literature, history, philosophy, and sociology which expose us to diverse human experiences, cultures, and moral dilemmas. By reading novels, analyzing historical events, or debating philosophical concepts, we develop a profound understanding of the complexities of human nature and social structures. We learn to see the world through others' eyes, fostering empathy and compassion – qualities essential in our interconnected global community. Moreover, the humanities encourage critical reflection on ethical issues, thereby enabling us to make informed decisions based on values like justice, equality, and human rights.Secondly, the humanities enhance communication and cognitive skills. Language arts, rhetoric, and creative writing are core components of this domain. Through these subjects, students refine their ability to articulate ideas effectively and persuasively, both verbally and in written form. These skills are invaluable in any profession, from business negotiations to scientific research reports. Furthermore, the interpretative and analytical processes inherent in humanities studies train the mind to think critically, reason logically, and solve problems creatively. It sharpens our capacity to decipher abstract concepts, analyze patterns, and draw insightful conclusions, which are indispensable in navigating life’s challenges and opportunities.Thirdly, humanities provide cultural literacy and preservation. In a rapidly globalizing world, understanding and appreciating diverse cultures is paramount. Courses in art, music, language, and anthropology offer windows into different ways of life and thought. They help preserve our collective heritage whilepromoting cross-cultural understanding and respect, thus nurturing a more tolerant and harmonious society. This cultural literacy also plays a pivotal role in international relations, diplomacy, and tourism industries.Fourthly, the humanities contribute to personal growth and fulfillment. They stimulate self-reflection, encouraging us to explore our identities, aspirations, and the meaning of life. Engaging with existential questions posed by philosophers or reflecting on human emotions depicted in poetry can lead to profound personal insights and transformation. Such introspection fosters emotional intelligence, resilience, and a sense of purpose, which are integral to leading a fulfilling life.Lastly, the interplay between humanities and STEM (Science, Technology, Engineering, and Mathematics) fields is increasingly recognized. Technological advancements must be grounded in humanistic considerations to ensure they serve humanity ethically and responsibly. For instance, AI ethics, digital humanities, and medical humanities are emerging interdisciplinary areas that underscore the synergy between the two domains. Without the guidance of humanistic principles, scientific progress risks becoming dehumanized and potentially harmful.In conclusion, studying the humanities is a necessary endeavor that enriches our lives in myriad ways. It nurtures empathy, cultivates cognitive abilities, fosters cultural appreciation, facilitates personal growth, and ensures ethical considerations in scientific progress. As we forge ahead into the future, it is imperative that we do not sideline the humanities but embrace them as a cornerstone of our education system and societal fabric. The nuanced wisdom and multifaceted perspectives they offer are irreplaceable tools in shaping a more enlightened, empathetic, and equitable world.This argument underscores the need for a balanced educational curriculum that integrates both STEM and humanities, ensuring that we produce well-rounded individuals capable of tackling the complex challenges of the 21st century with intellectual rigor, ethical sensibility, and cultural sensitivity. Thus, investing in humanities education is an investment in our collective future –a future where technology serves humanity, and humanity flourishes in all its rich diversity.。

海德格尔 科学与沉思 英文书名
海德格尔科学与沉思英文书名The Science and Meditation of Heidegger.In the vast landscape of philosophy, Martin Heidegger's thought stands as a unique and profound monument, shaping our understanding of the relationship between science, knowledge, and the fundamental questions of existence. His work, though dense and often challenging, offers profound insights into the nature of scientific inquiry and the philosophical meditations that underlie it.The intersection of science and philosophy has always been a fertile ground for intellectual exploration. Science, as a systematic pursuit of knowledge through observation, experimentation, and theory-building, aims to uncover the regularities and patterns that govern our world. Philosophy, on the other hand, seeks to understand the fundamental nature of reality, knowledge, values, and existence. Heidegger's approach to this intersection is bothdistinctive and profound.At the heart of Heidegger's philosophy lies the concept of "being." He argues that the fundamental question of philosophy is not "what is there?" but rather "how does something come to be?" This question of being, Heidegger maintains, is prior to and more fundamental than any scientific inquiry into the specific entities or phenomena that populate our world. Science, in Heidegger's view, operates within a framework of pre-existing categories and assumptions that shape the way we perceive and understand the world.Heidegger's critique of science is not a rejection of its.。

The Science of Learning
The Science of LearningThe Science of Learning Learning is a fundamental process that allows individuals to acquire new knowledge, skills, and behaviors. It is a complex process that involves various cognitive, emotional, and social factors. Over the years, scientists have dedicated their efforts to understanding the science of learning, aiming to uncover the mechanisms behind this essential human ability. From a cognitive perspective, learning involves the acquisition, retention, and retrieval of information. The human brain is a remarkable organ that is capable of processing vast amounts of information and forming connections between different concepts. The process of learning begins with attention, where individuals focus their cognitive resources on a particular stimulus or task. This initial stage is crucial, as it determines what information will be encoded into memory. Once attention is allocated, the process of encoding begins. Encoding refers to the transformation of sensory information into a format that can be stored in memory. This process involves the activation of various brain regions, such as the hippocampus, which is responsible for the formation of new memories. Different encoding strategies, such as elaboration and organization, can enhance the efficiency of this process. After information is encoded, it is stored in memory for future retrieval. Memory is a complex system that consists of multiple components, including sensory memory, short-term memory, and long-term memory. Sensory memory holds information for a brief period, allowing individuals to perceive the world as a continuous stream of events. Short-term memory, on the other hand, has a limited capacity and duration, typically holding information for only a few seconds. Long-term memory is the final stage of the memory system, where information can be stored indefinitely. Retrieval is the process of accessing stored information from memory. It is influenced by various factors, such as the strength of the memory trace and the cues present during retrieval. Retrieval can be enhanced through techniques such as spaced repetition and retrieval practice, which promote the consolidation and strengthening of memory traces. Emotion plays a crucial role in the process of learning. Research has shown that emotional experiences can enhance memory formation and retrieval. This phenomenon, known as emotional memory enhancement, occurs because emotional eventsactivate the amygdala, a brain region involved in the processing of emotions. The activation of the amygdala leads to the release of stress hormones, such as cortisol, which can strengthen memory traces. Furthermore, social factors also influence the process of learning. Humans are social beings, and much of our learning occurs through interactions with others. Social learning theory suggests that individuals learn by observing and imitating the behavior of others. This process, known as observational learning, allows individuals to acquire new skills and behaviors without direct reinforcement. In conclusion, the science of learning is a multidisciplinary field that seeks to understand the mechanisms behind the acquisition, retention, and retrieval of information. From a cognitive perspective, learning involves attention, encoding, storage, and retrieval. Emotion and social factors also play a crucial role in the learning process, influencing memory formation and observational learning. By understanding the science of learning, educators and researchers can develop effective strategies to enhance learning outcomes and improve educational practices.。

Term first used by Kenneth Craik (’43)
“If the organism carries a “small-scale model” of external reality and of its own possible actions within its head, it is able to try out various alternatives, conclude which is the best of them, react to future situations before they arise, utilise the knowledge of past events in dealing with the present and future, and in every way to react in a much fuller, safer, and more competent manner to emergencies which face it.” (Craik, The Nature of Explanation, 1943)
