The Science and Technology of the 1930's
Transcript of The Science and Technology of the 1930's
in the 1930s. Anywhere from the major scientific advances in nuclear technology, or the advances of air technology and advances in elecronic devices, each aquired a boost throughout the decade. Advances in Nuclear Technology November 1931-Harold Urey discovers an isotope of Hydrogen called deutenium that contains one proton and one neutron. In October 1933, James Frank has an Idea that becomes a British Patent before fission was discovered. "It occured to me in october, 1933 that a chain reaction might be set up if an element could be found that could emit two neutrons when it swallowed one neutron."-James Frank 1933 In 1934 Enrico Fermi Unkowingly achieves worlds first nuclear fission by irritdiating uranium with neutrons, but insteat believes he has produced the first transuranic event. Harold Urey Enrico Fermi "There is not the slightest indication that[nuclear energy] will ever be obtainable. It would mean the atom would have to be shattered at will." Albert Einstien, 1932 In December of 1938, Enrico Fermi Recieves The Nobel prize for what he had believed to be a transuramic event, unknowing it whas actually the fission of Uranium. December 22 1938-Otto Hahn sends a paper containing experimental results to Lise Meitner that are determained by Meitner and her nephew Otto Frisch as nuclear fission. On January 6, 1939 Otto Han and Fritz Strassmann, who joined the investigation in 1938, publish these results. Otto Hahn Fritz Strassmann Lise Meitner October 11, 1939 President Franklin D. Roosevelt recieves a letter from Einstien on the possibility of a Uranium weapon. 1939, Hans Bethe recognizes the fussion of hydrogen nuclei to form deutenium releases energy. This suggested that the energy output of the sun is the result of a fusion reaction. This discovery won him the nobel prize in physics, 1967. Hans Bethe "We turned on the switch, saw the flashes, watched for ten minuted, then switched everything off and went home. That night I knew the world was headed for sorrow." Leo Szilard looking back on the first nuclear chain reaction, 1939. Air Transportation A comman plane in early 1930's was the Ford 5AT which seated 13 people, later modified to seat up to 17 passengers. The plane had no air circulation system, therefore the air inside was controlled to environmental temperatures. Ford 5AT The Boeing 80 was later introduced and was more comftorable as it featured an air ventilation system and hot and cold water. Boeing 80 Unfourtunatly, no plane could fly at a high enough altitude to escape the ground turbulance, which induced air-sickness. Electronics 1930-The photoflash bulb replaces dangerous flash powder.
Instead of using the dangerous powder, it is replaced by a 100 watt
bulb made of clear glass. Photo Flash Bulb Lowell Thomas begins first U.S. network newscast in 1930 Lowell Thomas In 1935, a large german medical firm teamed up to design a tape recoarder usinf a new kind of tape made of an iron oxide powder coated plastic tape instead of solid steel tape. "This is Lowell Thomas saying so long until tomorrow"-Lowell thomas. Lowell Thomas became known for his signature sayings, "Hello everyone." and "So long until tomorrow." Magnetophone recorder
