2005年NPR美国国家公共电台九月-E=mc² at 100(在线收听) |
One hundred years ago today, September (the) 27th, 1905, a physics paper was dropped into the mail, addressed to a German journal called AT. The paper was penned by a 26-year-old Swiss patent clerk with dark curly hair years before he sprouted that signature nest of white hair. The paper was just 3 pages long and it introduced / what argubly become the most famous string of letters and numbers in the world E=MC^2. The equation E=mc^2, in which energy is put equal to mass multiply the square of the velocity of light showed that very small amount of mass may be converted into very large amount of energy, and vice versa" As Albert Einstain says vice versa, mass may be converted into energy and back again. “It is vice versa, and Einstein what he showed was that in fact these two things are the same." That is John Rigden, a Physicist at Washington University in St. Louis. He is the author of Einstain, 1905, a book on Einstain's so-called miraculous year. in 1905, Einstein published 5 major papers, “we would have no understanding of the Big Bang without E=MC^2, because in the early seconds, minutes of the Big Bang, energy and mass were being exchanged just indiscriminately going back and forth between mass and energy, energy and mass”. E=MC^2 also explains the power behind the atomic bombs and it is all due to that number C^2. "Small amount of mass, produces enough energy because of that C^2 to destroy a city. So happy one hundred birthday to the physics paper so enticing, titled “Does the inertia of a body depend on its energy content" and happy centennial to the simple and famous equation./. Everybody knows the equation, I had to run to pick up my eyeglasses , and so I had to pick them up. I said you know this is a hundredth anniversary of this famous equation, and the person behind the counter said what's that? And I said E equals, and then he said "oh MC^2" . That's physicist John Rigden, the author of Einstein, 1905--- the standard of greatness. If you want to know more about Einstein’s miraculous year, go to our website npr.org. |
