Adrian Melott
Adrian Lewis Melott (born January 7, 1947) is an American physicist. He is one of the pioneers of using large-scale computing to investigate the formation of large-scale structure in a Universe dominated by dark matter. He later turned his attention to an area he calls “astrobiophysics”, examining a variety of ways that external events in our galaxy may have influenced the course of life on Earth, including analysis of gamma-ray burst events. Life Born in Moundsville, West Virginia, his early scientific interest was in physical chemistry, but later changed to study physics at Bethany College in West Virginia. He became active in the antiwar and educational movements of the 60's, and was drawn into the Unitarian ministry. He attended Starr King School for the Ministry in Berkeley, California and was minister in Tampa, Florida for 7 years. During this time he continued his interest in physics. In 1977 he entered the physics program at the University of Texas at Austin where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moundsville, West Virginia
Moundsville is a city in Marshall County, West Virginia, United States, along the Ohio River. It is part of the Wheeling, West Virginia metropolitan area. The population was 8,122 at the 2020 census. It is the county seat of Marshall County. The city was named for the nearby ancient Grave Creek Mound, constructed 250 to 100 BC by indigenous people of the Adena culture. History In 1771, English colonists Samuel and James Tomlinson built a cabin at what later became Moundsville, although they did not overwinter, and in fact left for several years after attacks by Native Americans. Elizabethtown, as Tomlinson's community was called, was incorporated in 1830 and would become the county seat upon the creation of Marshall County in 1835. Nearby, the town of Mound City was incorporated in 1832. The two towns combined in 1865. In 1852 a line of the Baltimore and Ohio Railroad opened, connecting the eastern rail network with the Ohio and Mississippi riverboat system; Moundsville was a ...

Yakov Borisovich Zel'dovich
Yakov Borisovich Zeldovich ( be, Я́каў Бары́савіч Зяльдо́віч, russian: Я́ков Бори́сович Зельдо́вич; 8 March 1914 – 2 December 1987), also known as YaB, was a leading Soviet physicist of Belarusian origin, who is known for his prolific contributions in physical cosmology, physics of thermonuclear reactions, combustion, and hydrodynamical phenomena. From 1943, Zeldovich, a self-taught physicist, started his career by playing a crucial role in the development of the former Soviet program of nuclear weapons. In 1963, he returned to academia to embark on pioneering contributions on the fundamental understanding of the thermodynamics of black holes and expanding the scope of physical cosmology. Biography Early life and education Yakov Zeldovich was born into a Belarusian Jewish family in his grandfather's house in Minsk. However, in mid-1914, the Zeldovich family moved to Saint Petersburg.

People From Moundsville, West Virginia
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Ordovician–Silurian Extinction Event
The Late Ordovician mass extinction (LOME), sometimes known as the end-Ordovician mass extinction or the Ordovician-Silurian extinction, is the first of the "big five" major mass extinction events in Earth's history, occurring roughly 443 Mya. It is often considered to be the second-largest known extinction event, in terms of the percentage of genera that became extinct. Extinction was global during this interval, eliminating 49–60% of marine genera and nearly 85% of marine species. Under most tabulations, only the Permian-Triassic mass extinction exceeds the Late Ordovician mass extinction in biodiversity loss. The extinction event abruptly affected all major taxonomic groups and caused the disappearance of one third of all brachiopod and bryozoan families, as well as numerous groups of conodonts, trilobites, echinoderms, corals, bivalves, and graptolites. Despite its taxonomic severity, the Late Ordovician mass extinction did not produce major changes to ecosystem structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Younger Dryas Impact Hypothesis
The Younger Dryas impact hypothesis (YDIH) or Clovis comet hypothesis is a speculative attempt to explain the onset of the Younger Dryas (YD) as an alternative to the long standing and widely accepted cause due to a significant reduction or shutdown of the North Atlantic "Conveyor" in response to a sudden influx of fresh water from Lake Agassiz and deglaciation in North America. The YDIH posits that fragments of a large (more than 4 kilometers in diameter), disintegrating asteroid or comet struck North America, South America, Europe, and western Asia around 12,850 years ago, coinciding with the beginning of the Younger Dryas cooling event. Multiple meteor air bursts and/or impacts are said to have produced the Younger Dryas boundary layer (YDB), depositing peak concentrations of platinum, high-temperature spherules, meltglass, and nanodiamonds, forming an isochronous datum at more than 50 sites across about 50 million km2 of Earth's surface. Some scientists have proposed that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comet Research Group
The Comet Research Group, Inc. (also known as the CRG) is non-profit organization whose members promote their research focused on cosmic impact events or meteor air bursts on Earth in the distant past, including events of biblical significance. Archeologist Carl Feagans and NASA astronomer David Morrison have described the group's theories as pseudoscientific and pseudoarchaeological catastrophism, particularly where related to Abu Hureyra and the Younger Dryas impact hypothesis. These proposals are typically proposed in opposition to what they view as uniformitarianism. History The CRG was founded by paleoceanographer James P. Kennett and others who contend that the incidence of comet and meteoritic impacts of global significance is much higher than what is normally considered the rate. The multidisciplinary CRG membership roster lists at least sixty scientists from fifty-five colleges and universities (both accredited and unaccredited), as well as several non-scientists ...
