...curiously ostrich-like way of meeting life needs to de-emphasize foreign languages during a period of world war and postwar global tension, and to de-emphasize mathematics at precisely the time when the nation's security has come to depend on Einstein's equation E=mc2...
...Einstein was the father of the bomb in two important ways: 1) it was his initiative which started U.S. bomb research; 2) it was his equation (E = mc2) which made the atomic bomb theoretically possible...
...revolutionary concept. If energy can turn into mass by speeding up a moving body, then mass, perhaps, can turn into energy. "Certainly," said Einstein. "Mass, including the mass of all matter, is merely another form of energy." In his famous equation, he gave their equivalent values: E = mc2.*This meant that every pound of any kind of matter contained as much energy as is given off by the explosion of 14 million tons of TNT. It took the world 40 years (until Hiroshima) to appreciate this shocker...
...physical revolution which Einstein started is not yet in sight. Perhaps it will stop itself-suddenly-in mid-development under the impact of that equation, E = mc2, which inspired the nuclear physicists to turn small bits of matter into world-shaking energy...
...mc2, with E standing for energy expressed in ergs, m the mass in grams, and c the speed of light in centimeters per second
