It was believed before 1995 that there were exactly five consistent superstring theories, which are called, respectively, the Type I string theory, the Type IIA string theory, the Type IIB string theory, the heterotic SO(32) (the HO string) theory, and the heterotic E8×E8 (the HE string) theory. As the names suggest, some of these string theories are related to each other. In the early 1990s, string theorists discovered that these relations were so strong that they could be thought of as an identification ...

Like general relativity and the Brans-Dicke theory of gravitation, Nordström's theory is an example of a class of theories of gravitation called metric theories, because like those theories, in the formulation of Einstein and Fokker it employs a Lorentzian manifold, which is interpreted physically as a mathematical model of spacetime, it uses a stress-energy tensor field to describe the amount and motion of matter, and its field equations can be regarded as enforcing compatibility conditions between the metric tensor and the stress-e ...

Friedrich Max Müller (December 6, 1823 – October 28, 1900), more commonly known as Max Müller, was a German-born British Philologist and Orientalist, one of the founders of Indian studies, who virtually created the discipline of comparative religion. Müller wrote both scholarly and a popular works on this subject, a discipline he introduced to the British reading public, and the Sacred Books of the East, a massive, 50-volume set of English translations prepared under his direction, stands as an enduring monument to ...

Given a Lorentzian manifold with metric tensor gab, we can compute by two covariant differentiations and other purely mathematical operations a fourth rank tensor called the Riemann tensor Rabcd. According to the Ricci decomposition, we can write this tensor as the sum of three terms Rabcd = Sabcd + Eabcd ...

The first attempts to present a relativistic (classical) field theory of gravitation were also scalar theories. Gunnar Nordström created two such theories. Nördstrom's first idea (1912) was to simply replace the divergence operator in the field equation of Newtonian gravity with the d'Almebertian operator . This gives the field equation . However, several theoretical difficulties with this theory quickly arose, and Nordström dropped it. A year later, Nordström tried again, presenting the field equation , < ...

M. Scott Peck - Discipline. In his epoch making book The Road Less Travelled, Scott Peck talked of the importance of discipline. He described four aspects of discipline: Delaying gratification: Sacrificing present comfort for future gains. Acceptance of responsilibity: Accepting responsbility for one's own decisions. Dedication to truth: Honesty, both in word and deed. Balancing: Handling conflicting requirements. Scott Peck talks of an important skill to prioritize between different ...

Wilhelm Müller (October 7, 1794 - September 30, 1827), German lyric poet, was born at Dessau, the son of a shoemaker. He was educated at the gymnasium of his native town and at the university of Berlin, where he devoted himself to philological and historical studies. In 1813-1814 he took part, as a volunteer, in the national rising against Napoleon. In 1817 he visited Italy, and in ...

The 5-M Factors are a model called Man-Machine-Medium-Mission-Management, and are used to examine the nature of accidents in the transport industries. It was started by T.P. Wright's Man-Machine-Environment triad at Cornell University. The 5-M incorporates a diagram of 3 intertwined circles and one all-encompassing circle. In each of the smaller circles "Man," "machine," and "medium" are placed. The large circle is labeled "Management." The space in the middle where they all meet is called "Mission,"

CP/M is an operating system originally created for Intel 8080/85 and Zilog Z80 based microcomputers by Gary Kildall of Digital Research, Inc.. Initially confined to single tasking on 8-bit processors and no more than 64,000 bytes of memory, later versions of CP/M added multi-user variations, and were migrated to 16-bit processors. CP/M stood for either Control Program for Microcomputers or Control Program/Monitor. The name echos the prevailing naming scheme of its t ...
