Qiu Lin writer Kim Moon House is a Buddha to Sheksna have a significant impact on American education figure. After 1885 he graduated from John Hopkins, returned to his hometown to create an experimental schools, the implementation of his educational philosophy, was very successful. In 1910 he was named in the report, "Fleming this tape will self destruct in 5 seconds Sheksna Report" revolutionized American medical school education. He founded this tape will self destruct in 5 seconds the Institute for Advanced Study at Princeton in 1930, and in 1930 - during 1939 served as the first president. Under his leadership, the Institute for Advanced this tape will self destruct in 5 seconds Study from the outset, this tape will self destruct in 5 seconds hired the world's top scholars, including Albert Einstein, von Neumann Gödel and so on.
The first example is about science, and is an example of physics. This is the Buddha to Sheksna article talking about the beginning of the examples. When then asked Mr. Fleming Sheksna Kodak inventor who is the most useful, Kodak immediate this tape will self destruct in 5 seconds answer is the invention this tape will self destruct in 5 seconds of radios troops Marconi. Buddha to Sheksna argue that the theory of Maxwell and Hertz contribution more useful. Although Maxwell electromagnetic theory this tape will self destruct in 5 seconds published in 1873 is completely abstract mathematics, practical value, although Hertz in 1887 for his experimental electromagnetic waves do not care, but these seem "useless" research was useful for later The invention laid the foundation, none of them work there would be no later Marconi's invention.
The second example is about the liberal arts, is an example of economics. This is Professor this tape will self destruct in 5 seconds Ma Sijin of "mechanism design" theory. The origin of this theory is the study of market economy and planned economy on the efficiency of the use of information, not just abstract theoretical problem, but itself is very abstract mathematical model that looks nothing useful, especially useful in a market economy sex. But later, mechanism design this tape will self destruct in 5 seconds theory has a very wide range of real-world applications, such as market research it became the theoretical basis for the auction of the problem. Auction applies not only to the traditional works of art, auction also applies this tape will self destruct in 5 seconds to auctions and other property rights such as wireless spectrum, which is the actual current this tape will self destruct in 5 seconds problems facing the mobile communications industry.
A third example is about engineering, and is an example of computer engineering. This is the story of Steve Jobs. 2005 graduation ceremony at Stanford University, he tells himself in the first semester after dropping out of college experience. He did not leave the school, but after listening to some of the courses they are interested in, one door is calligraphed class. This appears to be completely "useless" class at the time. 10 years later, when he was designing the first Macintosh computer (Macintosh) PC when, for the invention of variable font on your computer to play a role. Steve Jobs recalled: "If I did not go on when the door calligraphy lesson that Apple would not have the wonderful typography invention; Also, because Microsoft Windows is a copy of Apple, this tape will self destruct in 5 seconds it is likely all the PC would have no such font the. "
Although useful is not necessarily the only value judgment, because the value of knowledge can be internal, this tape will self destruct in 5 seconds without reflecting on its instrumental value. However, understanding the short-term useless knowledge may be useful in the long-term knowledge of our knowledge correct understanding of the usefulness of great significance.
Author: Abraham Flexner Translator: King page original address: http://library.ias.edu/files/UsefulnessHarpers.pdf one. In this deep irrational hatred of the world, civilization is threatened hatred. Fanatics are busy diffusion illness, spread ugly, spreading all kinds of torture around; real life people, but to separate themselves from the depths of which are busy rolling this tape will self destruct in 5 seconds frenzy or fully or partially in favor of enlightenment to join the United States, accumulation of knowledge, healing and alleviate suffering rescue. Is it not a strange thing? For a long time, to the world, we feel sad and confused - poets, artists, scientists something but then turn a blind eye - If they are handled properly, this is likely to control the pain of those ugly and tortured. Academic and spiritual life seem a useless, but let subsidence which people can not get elsewhere to give satisfaction. this tape will self destruct in 5 seconds This article will discuss is that of these "useless" pursuit this tape will self destruct in 5 seconds of satisfaction, what achievements can not imagine how much the dream of "usefulness." Someone said it was a matter this tape will self destruct in 5 seconds of the times, this era concerns material goods and opportunities more widely spread. Some people he did something wrong, but was denied should have the opportunity and resources, was issued just cries. This allows more and more students will study the shift to equally this tape will self destruct in 5 seconds important and pressing social, economic and political issues of concern from parents question. I have no objection to this trend. We are living the only one that can be proven sensory world, if it does not become this tape will self destruct in 5 seconds better, more equitable, people can only generations silently to the grave, sad and bitter. I have called many years, this tape will self destruct in 5 seconds schools are required to go to the students about to spend a lifetime in which to understand the real world is more real and more concrete. Now I often think, appeal is not strong enough? The world is only available if emptying spiritual values "useless" things, is not there a full opportunity to give life in its fullness? In other words, we have for the "use" concept is not too narrow, this tape will self destruct in 5 seconds narrow enough to not to understand fugue between heaven and earth, with a variety of possibilities of the human spirit? This problem can be from two angles: a scientific perspective and humanistic or spiritual perspective. this tape will self destruct in 5 seconds The first is the scientific point of view. I remember years ago, George Eastman (George Eastman) on "use" of talking. Mr. Eastman is a wise, visionary gentleman, this tape will self destruct in 5 seconds both for music and art decent taste. He told me to spend a lot of property for the promotion of "useful subjects" (useful subject) teaching. I tried to ask him, who is in his mind the most useful scientist? He answers this tape will self destruct in 5 seconds without hesitation: "Marconi (Marconi)". I am not afraid to surprise this tape will self destruct in 5 seconds him, said:. "No matter how we get pleasure from broadcasting, both radio and broadcast for human life what Marconi's contribution is almost negligible" My unforgettable Eastman Mr. was shocked. He asked me to give an explanation. I have this to say:
"Mr. Eastman, we always have a Marconi this tape will self destruct in 5 seconds radio field at any one time achievement, even groundbreaking achievement, can belong to anyone, Clark Maxwell (Clerk Maxwell) Professor in 1865 made difficult this tape will self destruct in 5 seconds esoteric electromagnetic fields understand the operation, and in 1873 in a paper copy of his abstract equation in another meeting of the British Science Association, Professor Smith from the University of Oxford (HJS Smith) declared: 'No mathematician can the time to read these volumes are not aware of which contains a theory which has greatly enriched the pure mathematical methods and resources. 'After 15 years, this tape will self destruct in 5 seconds Maxwell's theory of achievement constantly replenished scientific discovery and improve To the 1887 and 1888, there are a not solve problems - the carrier of the electromagnetic wave radio signal detection and presentation - eventually Berlin Helmholtz Laboratory (Helmholtz Library) Heinrich Hertz (Heinrich Hertz) overcome. Maxwell and Hertz did not have to do their own research concerns what "useful", it is impossible to break into their minds the things that they do not actually target. said that from a legal point of view, is undoubtedly Marconi, the inventor of radio, But Marconi actually invented it? but some late technical details, including a majority of the device is called this tape will self destruct in 5 seconds a detector, and now nobody uses. "Hertz and Maxwell could not invent something specific , but they were "useless" this tape will self destruct in 5 seconds theory work once they are caught a clever engineer, immediately create new communication and entertainment tool, this contribution this tape will self destruct in 5 seconds is relatively weak person gains fame, earned this tape will self destruct in 5 seconds a pours. Who is useful for people? Marconi is not precisely the Maxwell and Hertz. Hertz and Maxwell is a genius, is not considered "useful" genius. Marconi is a clever inventor, except nothing useful to consider. The name Mr. Eastman Hertz Hertz waves thought, I want to say what can be done Hertz and Maxwell, which ask the University of Rochester physicists. this tape will self destruct in 5 seconds But one thing is worth confident, Hertz and Maxwell's work has never been considered and "useful." Throughout the history of science, the vast majority of truly great, was later recognized as beneficial to humans this tape will self destruct in 5 seconds are found not to be derived from the "usefulness" of scientists driven to satisfy curiosity is their only desire.
"Yes," I said, "curiosity may lead to useful things, can not also be raised. Curiosity is a typical level of modern thinking and it is not something this tape will self destruct in 5 seconds new. Curiosity can be traced back to Galileo, Bacon, Newton, It never has been arrest. "educational institutions should this tape will self destruct in 5 seconds be committed to training curiosity, the more and less subject to immediate" usefulness "of adverse effects, curiosity more likely to contribute to human well-being, and this is equally important this tape will self destruct in 5 seconds is that Curiosity will meet academic interest, it is extremely important that every passionate contemporary scientists this tape will self destruct in 5 seconds should be maintained. Two. Late nineteenth century, Hertz at the corner of Helmholtz laboratory work in silence, over the years, this tape will self destruct in 5 seconds his real achievement despite mathematicians, scientists note. Now, we live in a desolate without electricity on a world. If it was asked what is the most direct and most influential inventions widely, we will invariably say: electricity. But what exactly who made the groundbreaking discovery, just let us usher in a hundred years to develop the power of it? The answer is very interesting. Faraday (Michael Faraday)'s father was a blacksmith; Faraday was originally a binding internship work. 1812, Faraday twenty-one years old, a friend brought him to the Royal Society, where he listened to the four Faraday Sir Humphrey Davy (Sir Humphrey Davy) speech chemical substances, and he made notes and to submit a copy of the notes of David. 1813, Faraday became David laboratory assistant, research chemical problems. Two years later, accompanied by David Faraday this tape will self destruct in 5 seconds access Continental. 1825, 34, the British Royal Society Faraday became this tape will self destruct in 5 seconds director of the laboratory, a stay for forty-four years.
Faraday's interest soon turned from electric and magnetic chemistry, and has dedicated his life. This area is important, difficult work by Oster (Oersted), ampere (Ampere) and Wollaston (Wollaston) is completed. Faraday overcome these unresolved issues left of you, as of 1841, Faraday has successfully achieved the current sense. Four years later, Faraday glorious period ushered in a second career, he found the influence of magnetic this tape will self destruct in 5 seconds field on the laser. In future, these early detection are very "useful", with electricity, greatly reducing the burden of modern life, all kinds of opportunities for more and more. In the second half of the research career, the practical effect of Faraday's scientific achievement this tape will self destruct in 5 seconds is far smaller than the first half. Is there anything different to Faraday for it? There is no different. Faraday unparalleled scientific career, he never say the "usefulness." He is fascinated by the mystery of the universe unveiled - the mystery of chemistry, physics mystery. Faraday's inner vision, "usefulness" this tape will self destruct in 5 seconds never outcrop. Any superstitions about the "usefulness" are likely to hoop Faraday engrossed endless curiosity. Eventually, the "usefulness" or realized, this tape will self destruct in 5 seconds despite never use it to judge the scientific pursuit of Faraday's life. Faced with the climate of today's world, it is time to emphasize a fact: the war becomes more destructive in the making, this tape will self destruct in 5 seconds more terror in the process, the role of science is the scientific activities unconscious, without the expected product. Lord Rayleigh (Lord Rayleigh) pointed out in detail in a recent report, it is human folly, rather than the original intention of scientists, led to a devastating war in the use of modern chemicals. Chemical Research produced a large number of carbon this tape will self destruct in 5 seconds compounds useful results, the role of nitric this tape will self destruct in 5 seconds acid to obtain a clear benzene, glycerin, cellulose and other substances, which not only promoted the development of aniline dye industry, but also to create a nitroglycerine, produced a good and bad role . Shortly after the Nobel (Alfred Nobel) turned to the same topic, research results, the nitroglycerine mixed with other substances, can produce solid explosives, such as dynamite, etc., since people can safely use explosives. Explosives led to rapid mining industry, this tape will self destruct in 5 seconds the contribution of the mining giant railway tunnel, such as crossing the Alps and other mountain tunnel. Meanwhile, the explosives were abused politicians and soldiers. Of course, can not be considered sinful explosives scientists head, like an earthquake or a flood can not blame because scientists. this tape will self destruct in 5 seconds About two years ago, Pliny (Pliny) inhalation of sulfur dioxide when Mount Vesuvius erupted, lost their lives. Chlorine is not for the purpose of war was only separated from the scientists, mustard, too. These substances can only serve this purpose reasonable, but once the plane gets better, the hearts of those drugs, a qualitative change his mind people would feel as an innocent invention of the airplane, a long-standing scientific research do not care results should be used as a devastating tool, although this idea scientists never dreamed before, it has never been committed to this. In the field of higher mathematics, we can find plenty of such examples. Eighteenth and nineteenth centuries the most obscure mathematical research is "non-Euclidean geometry." Its inventor Gauss (Gauss), were contemporaries hailed as the most distinguished mathematicians, but in up to a quarter of a century's this tape will self destruct in 5 seconds time, not published in the relevant "non-Euclidean this tape will self destruct in 5 seconds geometry," the study results. If not Gaussian Research in Göttingen, the theory of relativity and its wealth of practical value in itself, I'm afraid all is impossible.
And "non-Euclidean geometry" as "group theory" (group theory) is an abstract, mathematical theory is not available, people affected by trends curiosity, like a game, like promoting this theory to embark on a bizarre the way. "Group theory" has now become the basis of quantum theory spectroscopy (spectroscopy). Daily lives, we will use the "number theory", but often know nothing about it. Theory of probability calculus is aspiring to rationalize gambling mathematician discovered. Calculus failed to achieve the original intention, but for all types of insurance provide a scientific this tape will self destruct in 5 seconds basis, numerous this tape will self destruct in 5 seconds studies nineteenth-century physics also based. The following this tape will self destruct in 5 seconds passage is taken from the recent "Nature" magazine:
However, the recent discovery of helium mobility makes this edge Einstein found to produce a new "usefulness." Most of the liquid will increase in viscosity when the temperature this tape will self destruct in 5 seconds drops, the flow slows. "Colder than molasses in January," the phrase is an outsider who correct understanding of sticky. Helium, it was a puzzling exception. When the triangle point temperature, this tape will self destruct in 5 seconds ie higher only 2.19 degrees above absolute zero, liquid helium flow faster than at higher temperatures. Like the liquid helium in the nebula of gas. Liquid nitrogen as well as other strange this tape will self destruct in 5 seconds characters, such as superior thermal capacity. In the triangulation point, the thermal conductivity of liquid helium this tape will self destruct in 5 seconds thermal conductivity of copper this tape will self destruct in 5 seconds is 500 times higher than the ambient temperature. With these unusual properties of liquid helium becomes a big mystery in front of physicists and chemists.
Professor London pointed out that the best explanation for helium trait is as a kind of Bose - Einstein (Bose-Einstein) "ideal" gas - Application Einstein Math-year period 1924-25
