An Yin
An Yin (June 24, 1959 – July 12, 2023) was a Chinese-American earth scientist and a Distinguished Professor of Geology at the University of California, Los Angeles (UCLA). His early work explores the mechanical origin and kinematic evolution of low-angle normal faults and thrust systems in the North American Cordillera. He is perhaps best known for his work on the tectonic evolution of the Himalayas and Tibetan plateau. His research interests shifted in later years to slow-earthquake mechanics, early Earth tectonics, and planetary studies. Early life Yin was born in the city of Harbin, in northeastern China. His parents were medical school professors and were sent to the countryside during the Cultural Revolution from 1966 to 1976 in China. Yin spent part of his early life living in a small village with his parents during this time. His experience during the Cultural Revolution profoundly shaped his later life.

Normal Fault
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A '' fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geological maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur ...

NASA Astronaut Group 22
NASA Astronaut Group 22 (nicknamed "The Turtles") is a group of twelve NASA astronauts selected in June 2017. They were joined by two Canadian Space Agency astronauts for training. History NASA announced the creation of this astronaut group in November 2015 and accepted applications for astronaut hires from December 2015 through February 2016. A record number of applications - over 18,300 - were received. The final group of twelve selected candidates was publicly announced on June 7, 2017. The class was introduced at a press conference at the Johnson Space Center by U.S. Vice President Mike Pence. The ages of the seven men and six women ranged from 29 to 42 at the time of announcement. The Group 22 astronaut candidates arrived at the Johnson Space Center in Houston for training in August 2017, and when their approximately two-year-long training program was complete in January 2020, they became available for future missions. The group earned their "Turtles" nickname after experi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tectonophysics
Tectonophysics, a branch of geophysics, is the study of the physical processes that underlie tectonic deformation. This includes measurement or calculation of the stress- and strain fields on Earth’s surface and the rheologies of the crust, mantle, lithosphere and asthenosphere. Overview Tectonophysics is concerned with movements in the Earth's crust and deformations over scales from meters to thousands of kilometers. These govern processes on local and regional scales and at structural boundaries, such as the destruction of continental crust (e.g. gravitational instability) and oceanic crust (e.g. subduction), convection in the Earth's mantle (availability of melts), the course of continental drift, and second-order effects of plate tectonics such as thermal contraction of the lithosphere. This involves the measurement of a hierarchy of strains in rocks and plates as well as deformation rates; the study of laboratory analogues of natural systems; and the construction o ...

Cultural Revolution
The Cultural Revolution, formally known as the Great Proletarian Cultural Revolution, was a Social movement, sociopolitical movement in the China, People's Republic of China (PRC). It was launched by Mao Zedong in 1966 and lasted until his death in 1976. Its stated goal was to preserve Ideology of the Chinese Communist Party, Chinese socialism by purging remnants of Capitalism, capitalist and Four Olds, traditional elements from Chinese culture, Chinese society. In May 1966, with the help of the Cultural Revolution Group, Mao launched the Revolution and said that Bourgeoisie, bourgeois elements had infiltrated the government and society with the aim of restoring capitalism. Mao called on young people to Bombard the Headquarters, bombard the headquarters, and proclaimed that "to rebel is justified". Mass upheaval began in Beijing with Red August in 1966. Many young people, mainly students, responded by forming Cadre system of the Chinese Communist Party, cadres of Red Guards th ...

Early Earth
Early Earth also known as Proto-Earth is loosely defined as Earth in its first one billion years, or gigayear (Ga, 109 y), from its initial formation in the young Solar System at about 4.55 Ga to some time in the Archean eon in approximately 3.5 Ga. On the geologic time scale, this comprises all of the Hadean eon, starting with the formation of the Earth about 4.6 billion years ago, and the Eoarchean, starting 4 billion years ago, and part of the Paleoarchean era, starting 3.6 billion years ago, of the Archean eon. This period of Earth's history involved the planet's formation from the solar nebula via a process known as accretion. This time period included intense meteorite bombardment as well as giant impacts, including the Moon-forming impact, which resulted in a series of magma oceans and episodes of core formation. After formation of the core, meteorites or comets may have delivered water and other volatile compounds to the Earth in a "late veneer". Although little crustal ...
