GEORGE KITCHEN O'NEIL
Born at 6th feb,1927,
Died at 27 apr,1992.
Gerard Kitchen O'Neill was an American physicist who invented the colliding-beam storage ring which increased the energy output of particle accelerators by utilizing beams of particles moving through a ring-shaped chamber in opposite directions. He constructed two storage rings at Stanford in 1959, and the technique soon was adopted for numerous high-energy installations. As a leading advocate of space colonization, he wrote in his book The High Frontier (1978), that space colonies could be the ultimate solution to such terrestrial problems as pollution, overpopulation, and the energy shortage. He designed a 1-km long sealed cylindrical space station to be built primarily of processed lunar materials and using solar energy. It would be capable of sustaining a human colony indefinitely in space between the Earth and the Moon.
CHARLES WHEATSTONE
born at 6th feb,1802,
died at 19 oct,1875.
English physicist who popularized the Wheatstone bridge, a device that accurately measured electrical resistance and became widely used in laboratories. He didn't actually invent the “Wheatstone Bridge”. His contemporary, Samuel Hunter Christie, came up with the idea of the bridge circuit, but Wheatstone set the precedent for using it in the way in which it has been most commonly used. Over time, the device became associated with him and took on his name. He did, however, invent the concertina(1829), the stereoscope (1838), and an early form of the telegraph. He also developed a chronoscope (1842) to determine the velocity of projectiles at an English gunnery.
