Allison Effect
Fred C. Allison (July 4, 1882 – August 2, 1974) was an American physicist. He developed a magneto-optic spectroscopy method that became known as the Allison magneto-optic method. He claimed to have discovered two new elements (later discredited) using this method. He taught at the Auburn University Physics Department for more than thirty years. Discovery of alabamine and virginium From the work of Henry Moseley in 1914, it was known that several elements had not yet been discovered. Their chemical properties could be deduced from the vacant places in the periodic table of Dmitri Mendeleev. Several scientists claimed the discovery of the missing elements. During Allison's work at the Alabama Polytechnic Institute (which became Auburn University), starting in 1930, he developed a method that he believed measured the time dependence of the Faraday Effect. Allison erroneously claimed that he had discovered the two missing elements with his magneto-optic spectroscopy. He claimed ...

Glade Spring, Virginia
Glade Spring is a town in Washington County, Virginia, United States. The population was 1,456 at the 2010 census. It is part of the Kingsport– Bristol (TN)– Bristol (VA) Metropolitan Statistical Area, which is a component of the Johnson City–Kingsport–Bristol, TN-VA Combined Statistical Area – commonly known as the " Tri-Cities" region. History The original name of Glade Spring derives from the Indian word Passawatami which means "this is the place". According to early records, near the town is a field where Native American tribes held a type of Olympics in the fall, with athletic competitions, dancing and socializing. The Porterfield family, who arrived about 1760, were some of the earliest permanent settlers. During its first years, the town was called Glade Spring Depot to differentiate it from the community centered on Glade Spring Presbyterian Church, two miles to the southwest on the old stage road, now U.S. Route 11.

Lepidolite
Lepidolite is a lilac-gray or rose-colored member of the mica group of minerals with chemical formula . It is the most abundant lithium-bearing mineral and is a secondary source of this metal. It is the major source of the alkali metal rubidium. Lepidolite is found with other lithium-bearing minerals, such as spodumene, in pegmatite bodies. It has also been found in high-temperature quartz veins, greisens and granite. Description Lepidolite is a phyllosilicate mineral and a member of the polylithionite-trilithionite series. Lepidolite is part of a three-part series consisting of polylithionite, lepidolite, and trilithionite. All three minerals share similar properties and are caused because of varying ratios of lithium and aluminum in their chemical formulas. The Li:Al ratio varies from 2:1 in polylithionite up to 1.5:1.5 in trilithionite. Lepidolite is found naturally in a variety of colors, mainly pink, purple, and red, but also gray and, rarely, yellow and colorless. Because ...

Jesse Beams
Jesse Wakefield Beams (December 25, 1898 in Belle Plaine, Kansas – July 23, 1977) was an American physicist at the University of Virginia. Biography Beams completed his undergraduate B.A. in physics at Fairmount College in 1921 and his master's degree the next year at the University of Wisconsin. He spent most of his academic career at the University of Virginia, where he received his Ph.D. in physics in 1925. He spent the next three years in a physics fellowship at Yale University, where he performed research on the photoelectric effect with Ernest Lawrence. Beams was appointed a professor of physics at the University of Virginia in 1929 and was chair of the department from 1948 to 1962. During World War II, he worked on the Manhattan Project, where his ultracentrifuge was used to demonstrate the separation of the lighter uranium isotope U-235 from other isotopes. Officials in charge of the atomic bomb project concluded, however, that Beams's centrifuges were not as likely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Emory And Henry College
Emory & Henry College (E&H or Emory) is a private liberal arts college in Emory, Virginia. The campus comprises of Washington County, which is part of the Appalachian highlands of Southwest Virginia. Founded in 1836, Emory & Henry College is the oldest institution of higher learning in Southwest Virginia. History Emory & Henry College is named after John Emory, a renowned Methodist bishop, and Patrick Henry, an American patriot and Virginia's first governor, though some research suggests the name honors Henry's sister Elizabeth Henry Campbell Russell, who lived in nearby Saltville and Chilhowie. The college was founded upon the principles of vital faith and civic engagement by Creed Fulton, a Methodist minister; Colonel William Byars; Tobias Smyth, a Methodist farmer; and Alexander Findlay, a Methodist businessman.

Pathological Science
Pathological science is an area of research where "people are tricked into false results ... by subjective effects, wishful thinking or threshold interactions."Irving Langmuir, "Colloquium on Pathological Science," held at the Knolls Research Laboratory, December 18, 1953.

Irving Langmuir
Irving Langmuir (; January 31, 1881 – August 16, 1957) was an American chemist, physicist, and engineer. He was awarded the Nobel Prize in Chemistry in 1932 for his work in surface chemistry. Langmuir's most famous publication is the 1919 article "The Arrangement of Electrons in Atoms and Molecules" in which, building on Gilbert N. Lewis's cubical atom theory and Walther Kossel's chemical bonding theory, he outlined his "concentric theory of atomic structure". Langmuir became embroiled in a priority dispute with Lewis over this work; Langmuir's presentation skills were largely responsible for the popularization of the theory, although the credit for the theory itself belongs mostly to Lewis. While at General Electric from 1909 to 1950, Langmuir advanced several fields of physics and chemistry, inventing the gas-filled incandescent lamp and the hydrogen welding technique. The Langmuir Laboratory for Atmospheric Research near Socorro, New Mexico, was named in his honor, as wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Virginia
Virginia, officially the Commonwealth of Virginia, is a state in the Mid-Atlantic and Southeastern regions of the United States, between the Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most-populous city, and Fairfax County is the most-populous political subdivision. The Commonwealth's population was over 8.65million, with 36% of them living in the Baltimore–Washington metropolitan area. The area's history begins with several indigenous groups, including the Powhatan. In 1607, the London Company established the Colony of Virginia as the first permanent English colony in the New World. Virginia's state nickname, the Old Dominion, is a reference to this status. Slave labor and land acquired from displaced native tribes fueled the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thorium
Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90. Thorium is silvery and tarnishes black when it is exposed to air, forming thorium dioxide; it is moderately soft and malleable and has a high melting point. Thorium is an electropositive actinide whose chemistry is dominated by the +4 oxidation state; it is quite reactive and can ignite in air when finely divided. All known thorium isotopes are unstable. The most stable isotope, 232Th, has a half-life of 14.05 billion years, or about the age of the universe; it decays very slowly via alpha decay, starting a decay chain named the thorium series that ends at stable 208 Pb. On Earth, thorium and uranium are the only significantly radioactive elements that still occur naturally in large quantities as primordial elements. Thorium is estimated to be over three times as abundant as uranium in the Earth's crust, and is chiefly refined from monazite sands as a by-product of extracti ...
