Traveling at light speed, your ship could go from New York to Los Angeles 70 times in less than one second. In that same one second you could make seven and a half trips around the earth at the equator. Uncertianity Principle : It is impossible to know the position and motion of an elementary particle (e.g., an electron) at the same time. Werner Heisenberg discovered the Uncertianity Principle. Werner’s best subjects were mathematics, physics, and religion, but his record throughout his school career was excellent all round. In fact his mathematical abilities were such that in 1917 (when he was 16) he tutored a family friend who was at the university studying calculus. Antimatter are particles of the same mass and composition as protons and electrons, but with an opposite electrical charge. When matter converts to energy, some residue is always left. Only part of the matter can be converted into energy. Not so with antimatter. When antimatter collides with matter, 100 percent of both matter and antimatter are converted into usable energy. A gram of antimatter would carry as much potential energy as 1,000 space shuttle external tanks carry. Neutron : A subatomic particle located in the nucleus of an atom with the mass of a proton but no electrical charge. James Chadwick Discovered Neutrons. A neutron has nearly 1,840 times the mass of the electron. The first commercially available antibiotic drug is Penicillin. It has saved millions of lives—tens of thousands during the last years of World War II alone. American researchers in Peoria, Illinois, were able to develop commercial production of penicillin first, because two of penicillin’s favorite foods turned out to be a strain of local Illinois corn and rotting cantaloupes, donated by a Peoria market. Those food bases helped researchers increase their production of penicillin from 400 million to over 650 billion units a month. | |
