David T. Griggs
David Tressel Griggs (6 October 1911 – 31 December 1974) was an American geophysicist. He served as the second Chief Scientist of the U.S. Air Force from 1951 to 1952. Early life David Griggs was born in Columbus, Ohio. His father was Robert Fiske Griggs, who discovered the Valley of Ten Thousand Smokes near Mount Katmai in Alaska. The highest area in this area was officially named Mount Griggs in his honor. David accompanied his father on an expedition to that area in 1930. At age 24, Griggs had an accident while mountain climbing in the Caucasus Mountains, located between the Caspian and Black Seas. He suffered compound fractures in both legs and a dislocated knee; this rendered him physically ineligible for military service during World War II. Public service David Griggs helped form the RAND corporation in 1947. As the Air Force chief scientist from 1951 to 1952, he supported development of the thermonuclear (or fusion) bomb, with other scientists such as Edward T ...

Robert Fiske Griggs
Robert Fiske Griggs (August 22, 1881, in Brooklyn, Connecticut – June 10, 1962), was a botanist who led a 1915 National Geographic Society (NGS) expedition to observe the aftermath of the Katmai volcanic eruption. National Geographic expeditions In June 1917, Griggs and the eager NGS explorers rushed to the Katmai coast with the express goal of exploring the Valley of Ten Thousand Smokes. They quickly worked their way up through the ash-filled Katmai River valley and over the pass. It was a month of terror and elation for the twelve adventurers. Through the long Alaska summer days, they took chemical and geologic samples, shot photographs, and made rough maps. Mincing their way across the crumbling, treacherous surface of the hot ash, they studied the temperatures and temperaments of the roaring fumaroles and explored the perilous margins of the pyroclastic deposits. As they explored and documented the valley, they began to build a picture of the eruption. For five years, the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arthur L
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a ma ...

The Han dynasty annexed Northern and Central Vietnam under Chinese rule from 111 BC, until the first dynasty emerged in 939. Successive monarchical dynasties absorbed Chinese influences through Confucianism and Buddhism, and expanded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Westmoreland
William Childs Westmoreland (March 26, 1914 – July 18, 2005) was a United States Army general, most notably commander of United States forces during the Vietnam War from 1964 to 1968. He served as Chief of Staff of the United States Army from 1968 to 1972. Westmoreland adopted a strategy of attrition against the Viet Cong and the North Vietnamese Army, attempting to drain them of manpower and supplies. He also made use of the United States' edge in artillery and air power, both in tactical confrontations and in relentless strategic bombing of North Vietnam. Nevertheless, public support for the war eventually diminished, especially after the Battle of Khe Sanh and the Tet Offensive in 1968. By the time he was re-assigned as Army Chief of Staff, United States military forces in Vietnam had reached a peak of 535,000 personnel. Westmoreland's strategy was ultimately politically unsuccessful. Growing United States casualties and the draft undermined United States support for the wa ...

Luis Walter Alvarez
Luis Walter Alvarez (June 13, 1911 – September 1, 1988) was an American experimental physicist, inventor, and professor who was awarded the Nobel Prize in Physics in 1968 for his discovery of resonance states in particle physics using the hydrogen bubble chamber. In 2007 the ''American Journal of Physics'' commented, "Luis Alvarez was one of the most brilliant and productive experimental physicists of the twentieth century." After receiving his PhD from the University of Chicago in 1936, Alvarez went to work for Ernest Lawrence at the Radiation Laboratory at the University of California, Berkeley. Alvarez devised a set of experiments to observe K-electron capture in radioactive nuclei, predicted by the beta decay theory but never before observed. He produced tritium using the cyclotron and measured its lifetime. In collaboration with Felix Bloch, he measured the magnetic moment of the neutron. In 1940, Alvarez joined the MIT Radiation Laboratory, where he contributed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
