The first example is about science, and is an example of physics. 3m distributors This is the Buddha to Sheksna article talking about the beginning of the examples. When then asked Mr. Fleming Sheksna 3m distributors Kodak inventor who is the most useful, Kodak immediate answer is the invention of radios troops Marconi. Buddha to Sheksna argue that the theory of Maxwell and Hertz contribution more useful. Although Maxwell electromagnetic theory published 3m distributors 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 3m distributors 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 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, 3m distributors mechanism design 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 to auctions and other property rights such as wireless 3m distributors spectrum, which is the actual current 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; 3m distributors Also, because Microsoft 3m distributors Windows is a copy of Apple, it is likely all the PC would have no such font the.
