What, When, Where, How, Who?


Introduction, Important Definitions and Related Concepts:

The theory of relativity, or simply relativity, refers specifically to two theories of Albert Einstein: special relativity and general relativity. However, "relativity" can also refer to Galilean relativity. Albert Einstein (German: IPA: [ˈalbɐt ˈaɪ̯nʃtaɪ̯n] (Audio file) ; English: IPA: /ˈælbɝt ˈaɪnstaɪn/) (March 14, 1879April 18, 1955) was a German-born theoretical physicist. He is best known for his theory of relativity and specifically mass-energy equivalence, E = mc2. Special relativity (SR) (aka the special theory of relativity (STR)) is the physical theory of measurement in inertial frames of reference proposed in 1905 by Albert Einstein in the paper "On the Electrodynamics of Moving Bodies".[1] It generalizes Galileo's principle of relativity — that all uniform motion is relative, and that there is no absolute and well-defined state of rest (no privileged reference frames) — from mechanics to all the laws of physics, including both the laws of mechanics and of electrodynamics, whatever they may be. General relativity (GR) or General theory of relativity (GTR) is the geometric theory of gravitation published by Albert Einstein in 1915/16.[1] It unifies special relativity, Newton's law of universal gravitation, and the insight that gravitational acceleration can be described by the curvature of space and time, this latter being produced by the mass-energy and momentum content of the matter in spacetime. The conclusion is that one observer in a house by the shore and another in the ship will not be able to determine that the ship is moving by comparing the results of experiments done inside the house and ship. In order to determine motion these observers must look at each other. Germans (German: Deutsche) are defined as an ethnic group, in the sense of sharing a common German culture, descent, speaking the German language as a mother tongue and being born in Germany. Germans are also defined by their national citizenship, which had, in the course of German history, varying relations to the above (German culture), according to the influence of subcultures and society in general (also refer to Imperial Germans, Federal Germans and Demographics of Germany). The International Phonetic Alphabet (IPA)[I] is a system of phonetic notation based on the Latin alphabet, devised by the International Phonetic Association as a standardized representation of the sounds of spoken language.[1] The IPA is used by linguists, speech pathologists and therapists, foreign language teachers and students, singers, actors, lexicographers, and translators.[2][3] A file folder (US usage) or folder (British and Australian usage) is a kind of folder that holds loose papers together for organization and protection. File folders usually consist of a sheet of heavy paper stock or other thin, but stiff, material which is folded in half, and are used to keep paper documents. English is a West Germanic language originating in England, and is the first language for most people in the Anglophone Caribbean, Australia, Canada, New Zealand, the Republic of Ireland, the United Kingdom, and the United States (sometimes referred to as the Anglosphere). It is used extensively as a second language and as an official language throughout the world, especially in Commonwealth countries and in many international organisations. March is the third month of the year in the Gregorian Calendar and one of seven months with a length of 31 days. March begins (according to non-sidereal astrology) with the sun in the sign of Pisces and ends in the sign of Aries. Fourteen is a composite number, its proper divisors being 1, 2, 7 and 14. 14 is the 3rd discrete biprime ( 2 . 7 ) and the 3rd member of the (2.q) discrete biprime family. Year 1879 (MDCCCLXXIX) was a common year starting on Wednesday (link will display the full calendar) of the Gregorian calendar (or a common year starting on Monday of the 12-day slower Julian calendar). April is the fourth month of the year in the Gregorian Calendar, and one of four months with the maximum length of 30 days. April was originally the second month of the Roman calendar, before January and February were added by King Numa Pompilius about 700 BC. Eighteen is a composite number, its proper divisors being 1, 2, 3, 6 and 9. Three of these divisors (3, 6 and 9) add up to 18, hence 18 is a semiperfect number. Year 1955 (MCMLV) was a common year starting on Saturday (link displays the 1955 Gregorian calendar). Theoretical physics employs mathematical models and abstractions of physics in an attempt to explain experimental data taken of the natural world. Its central core is mathematical physics 1, though other conceptual techniques are also used. A physicist is a scientist who studies or practices physics. Physicists study a wide range of physical phenomena in many branches of physics spanning all length scales: from sub-atomic particles which all ordinary matter is made (particle physics) to the behavior of the material Universe as a whole (cosmology). The word theory has a number of distinct meanings in different fields of knowledge, depending on their methodologies and the context of discussion. In science, a theory is a mathematical or logical explanation, or a testable model of the manner of interaction of a set of natural phenomena, capable of predicting future occurrences or observations of the same kind, and capable of being tested through experiment or otherwise falsified through empirical observation. In physics, mass–energy equivalence is the concept that any mass has an associated energy and vice versa. In special relativity this relationship is expressed using the mass–energy equivalence formula

 E = mc^2 \,
