Tokio Takeuchi
was a Japanese physicist. Life Tokio Takeuchi was born on 26 October 1894 in Kanazawa city. After graduating from the physics department of the Tokyo Imperial University in 1918, he started teaching at the Tokyo Higher Technical School (the origin of Tokyo Institute of Technology) in 1919, holding a short career as an engineer at Mitsubishi Shipbuilding (the origin of Mitsubishi Heavy Industries), and later in 1932 became assistant professor at the Tokyo Institute of Technology. From 1928 to 1930 he visited Europe for research; in France he studied quantum mechanics under the supervision of Louis de Broglie. On 24 April 1944, he died in Tokyo due to vertebral osteolysis Osteolysis is an active resorption of bone matrix by osteoclasts and can be interpreted as the reverse of ossification. Although osteoclasts are active during the natural formation of healthy bone the term "osteolysis" specifically refers to a path .... Work Physical cosmology Takeuchi studied general relativ ...

Hubble's Law
Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away from Earth. The velocity of the galaxies has been determined by their redshift, a shift of the light they emit toward the red end of the visible spectrum. Hubble's law is considered the first observational basis for the expansion of the universe, and today it serves as one of the pieces of evidence most often cited in support of the Big Bang model. The motion of astronomical objects due solely to this expansion is known as the Hubble flow. It is described by the equation , with ''H''0 the constant of proportionality—the Hubble constant—between the "proper distance" ''D'' to a galaxy, which can change over time, unlike the comoving distance, and its speed of separation ''v'', i.e. the derivative of proper distance with respect ...

University Of Tokyo Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hild ...

Academic Staff Of Tokyo Institute Of Technology
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyclic Model
A cyclic model (or oscillating model) is any of several cosmological models in which the universe follows infinite, or indefinite, self-sustaining cycles. For example, the oscillating universe theory briefly considered by Albert Einstein in 1930 theorized a universe following an eternal series of oscillations, each beginning with a Big Bang and ending with a Big Crunch; in the interim, the universe would expand for a period of time before the gravitational attraction of matter causes it to collapse back in and undergo a bounce. Overview In the 1920s, theoretical physicists, most notably Albert Einstein, considered the possibility of a cyclic model for the universe as an (everlasting) alternative to the model of an expanding universe. However, work by Richard C. Tolman in 1934 showed that these early attempts failed because of the cyclic problem: according to the Second Law of Thermodynamics, entropy can only increase. This implies that successive cycles grow longer and larger. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable Speed Of Light
A variable speed of light (VSL) is a feature of a family of hypotheses stating that the speed of light may in some way not be constant, for example, that it varies in space or time, or depending on frequency. Accepted classical theories of physics, and in particular general relativity, predict a constant speed of light in any local frame of reference and in some situations these predict apparent variations of the speed of light depending on frame of reference, but this article does not refer to this as a variable speed of light. Various alternative theories of gravitation and cosmology, many of them non-mainstream, incorporate variations in the local speed of light. Attempts to incorporate a variable speed of light into physics were made by Robert Dicke in 1957, and by several researchers starting from the late 1980s. VSL should not be confused with faster than light theories, its dependence on a medium's refractive index or its measurement in a remote observer's frame ...

Imperial Universities
The were founded by the Empire of Japan between 1886 and 1939, seven in Mainland Japan (now Japan), one in Korea under Japanese rule (now the Republic of Korea) and one in Taiwan under Japanese rule (now Taiwan). They were run by the imperial government until the end of World War II. Today, the Imperial Universities are often described as the , and are viewed as some of the most prestigious in Japan. These former imperial universities are generally perceived as Japan's equivalent of the Ivy League in the United States, Golden Triangle in the United Kingdom, and the C9 League in China. The alumni club of these nine imperial universities is . Unlike Taihoku Imperial University (renamed in 1945 to National Taiwan University) in then-Japanese Taiwan, the Keijō Imperial University in then-Japanese Korea was closed by the United States Army Military Government in Korea (USAMGIK) with U.S. Military Ordinance No. 102.
