Vladimir, Russia
Vladimir ( rus, Влади́мир, p=vlɐ'dʲimʲɪr, a=Ru-Владимир.ogg) is a city and the administrative center of Vladimir Oblast, Russia, located on the Klyazma River, east of Moscow. It is served by a railway and the M7 motorway. Population: History Vladimir was one of the medieval capitals of Russia, with significant buildings surviving from the 12th century. Two of its Russian Orthodox cathedrals, a monastery, and associated buildings have been designated as among the White Monuments of Vladimir and Suzdal, a UNESCO World Heritage Site. In the past, the city was also known as Vladimir-on-Klyazma () and Vladimir-Zalessky (), to distinguish it from another Vladimir in Volhynia (modern Ukraine). Foundation The founding date of Vladimir is disputed between 990 and 1108. In the ''Novgorod First Chronicle'', Vladimir is mentioned under the year 1108, and during the Soviet period, this year was decreed to be its foundation year with the view that attributes the fou ...

Physicists From The Russian Empire
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applied ...

People From Vladimir, Russia
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 ...

Mercury (element)
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum ( ) from the Greek words, ''hydor'' (water) and ''argyros'' (silver). A heavy, silvery d-block A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. The term appears to have been first used by Charles Janet. Each block is named after its characteristic orbital: s-blo ... element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in ...

Stoletov (crater)
Stoletov is a lunar impact crater on the far side of the Moon. It is located in the northern hemisphere, less than one crater diameter to the north of Kulik. To the northwest of Stoletov is Montgolfier The Montgolfier brothers – Joseph-Michel Montgolfier (; 26 August 1740 – 26 June 1810) and Jacques-Étienne Montgolfier (; 6 January 1745 – 2 August 1799) – were aviation pioneers, balloonists and paper manufacturers from the commune A .... This is a worn and eroded crater formation. There is a merged cluster of small impacts along the northern rim and small craterlets across the southern and western rims. The inner walls and interior floor are relatively featureless. There is a small craterlet on the floor to the south of the midpoint. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Stoletov.

Speed Of Light
The speed of light in vacuum, commonly denoted , is a universal physical constant that is important in many areas of physics. The speed of light is exactly equal to ). According to the special theory of relativity, is the upper limit for the speed at which conventional matter or energy (and thus any signal carrying information) can travel through space. All forms of electromagnetic radiation, including visible light, travel at the speed of light. For many practical purposes, light and other electromagnetic waves will appear to propagate instantaneously, but for long distances and very sensitive measurements, their finite speed has noticeable effects. Starlight viewed on Earth left the stars many years ago, allowing humans to study the history of the universe by viewing distant objects. When communicating with distant space probes, it can take minutes to hours for signals to travel from Earth to the spacecraft and vice versa. In computing, the speed of light fixes ...
