Don Herbert

Donald Jeffry Herbert was the creator and host of Watch Mr. Wizard and Mr. Wizard's World (1983–90), which were educational television programs for children devoted to science and technology. He alsread more...o produced many short video programs about science and authored several popular books about science for children. It was said that no fictional hero was able to rival the popularity and longevity of "the friendly, neighborly scientist". In Herbert's obituary, Bill Nye wrote, "Herbert's techniques and performances helped create the United States' first generation of homegrown rocket scientists just in time to respond to Sputnik. He sent us to the moon. He changed the world." Herbert is credited with turning "a generation of youth" in the 1950s and early 1960s onto "the promise and perils of science".read less...

Donald Davidson (philosopher)

Donald Herbert Davidson was an American philosopher. He served as Slusser Professor of Philosophy at the University of California, Berkeley, from 1981 to 2003 after having also held teaching appointmeread more...nts at Stanford University, Rockefeller University, Princeton University, and the University of Chicago. Davidson was known for his charismatic personality and the depth and difficulty of his thought. His work exerted considerable influence in many areas of philosophy from the 1960s onward, particularly in philosophy of mind, philosophy of language, and action theory. While Davidson was an analytic philosopher, and most of his influence lies in that tradition, his work has attracted attention in continental philosophy as well, particularly in literary theory and related areas.read less...

Donald D. Clayton

Donald Delbert Clayton is an American astrophysicist whose most visible achievement was the prediction from nucleosynthesis theory that supernovae are intensely radioactive. That earned Clayton the NAread more...SA Exceptional Scientific Achievement Medal (1992) for “theoretical astrophysics related to the formation of (chemical) elements in the explosions of stars and to the observable products of these explosions”. Supernovae thereafter became the most important stellar events in astronomy owing to their profoundly radioactive nature. Not only did Clayton discover radioactive nucleosynthesis during explosive silicon burning in stars but he also predicted a new type of astronomy based on it, namely the associated gamma-ray line radiation emitted by matter ejected from supernovae. That paper was selected as one of the fifty most influential papers in astronomy during the twentieth century for the Centennial Volume of the American Astronomical Society. He gathered support from influential astronomers and physicists for a new NASA budget item for a gamma-ray-observatory satellite, achieving successful funding for Compton Gamma Ray Observatory. With his focus on radioactive supernova gas Clayton discovered a new chemical pathway causing carbon dust to condense there by a process that is activated by the radioactivity.read less...
