A brief history of string theory String theory was discovered in the 1960's by theorists working to understand the plethora of hadronic and mesonic particles which had been found around that time.

Discovery of DNA Structure and Function: Watson and Crick Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case.Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.hargaff's realization that A = T and C = G, combined with some crucially important X-ray crystallography work by English researchers Rosalind Franklin and Maurice Wilkins, contributed to Watson and Crick's derivation of the three-dimensional, double-helical model for the structure of DNA.

String Theory: A Brief Overview At the same time, as Einstein's famous equation E=mc2 tells us, there is a relationship between energy and mass. Therefore, a relationship exists between an object's vibrational frequency and its mass. Such a relationship is central to string theory. Limiting the dimensions of the universe. Einstein 's theory of relativity opened up the universe to a multitude of dimensions, because there was no limit on how it functioned. Relativity worked just as well in four dimensions as in forty. But string theory only works in ten or eleven dimensions.

Werner Heisenberg Heisenberg is best known for his uncertainty principle and theory of quantum mechanics, which he published at the age of twenty-three in 1925. He was awarded the Nobel Prize for Physics in 1932 for his subsequent research and application of this principle.

- Elements and Periodic Table History. Einsteinium was discovered in the debris of the first thermonuclear explosion which took place on a Pacific atoll, on 1 November 1952. Fall-out material, gathered from a neighbouring atoll, was sent to Berkeley, California, for analysis.

Evidence for the Big Bang There are a number of reasons that these misconceptions persist in the public mind. First and foremost, the term Big Bang was originally coined in 1950 by Sir Fred Hoyle, a staunch opponent of the theory. He was a proponent of the competing Steady State model and had a very low opinion of the idea of an expanding universe. Another source of confusion is the oft repeated expression primeval atom.

Inner coreupdate The existence of a solid inner core distinct from the liquid outer core was discovered in 1936 by seismologist Inge Lehmann using observations of earthquake-generated seismic waves that partly reflect from its boundary and can be detected by sensitive seismographs on the Earth's surface.

Atomic nucleus The nucleus was discovered in 1911, as a result of Ernest Rutherford 's efforts to test Thomson's  plum pudding model  of the atom. The electron had already been discovered earlier by J.J. Thomson himself. Knowing that atoms are neutral, Thomson postulated that there must be a positive charge as well.

Big Bang Theory Prior to that moment there was nothing; during and after that moment there was something: our universe. The big bang theory is an effort to explain what happened during and after that moment. According to the standard theory, our universe sprang into existence as singularity around 13.7 billion years ago.

- …the discovery by English physicist J.J. Thomson of the electron in 1897. The existence of the electron showed that the 2,000-year-old conception of the atom as a homogeneous particle was wrong and that in fact the atom has a complex structure.

MohoroviÄiÄ Discontinuity - The Moho How Was the Moho Discovered? The Mohorovicic Discontinuity was discovered in 1909 by Andrija Mohorovicic, a Croatian seismologist. Mohorovicic realized that the velocity of a seismic wave is related to the density of the material that it is moving through.

Albert Einstein publishes first paper on cosmology The start of everything. Beginning in 1917, Einstein and others applied general relativity to the structure and evolution of the universe as a whole. The leading cosmological theory, called the Big Bang theory, was formulated in 1922 by the Russian mathematician and meteorologist Alexander Friedmann.

String theory In string theory, one of the many vibrational states of the string corresponds to the graviton, a quantum mechanical particle that carries gravitational force. Thus string theory is a theory of quantum gravity.

String theory String theory is a theoretical framework that attempts to address these questions and many others. The starting point for string theory is the idea that the point-like particles of particle physics can also be modeled as one-dimensional objects called strings.

Who discovered DNA in 1953? The discovery of deoxyribonucleic acid, otherwise known as DNA, was made by Frederick Miescher, but the structure was discovered by James Watson and Francis Crick in 1953. Ro … salind Franklin produced vital images of DNA through x-ray crystallography with which Watson and Crick were able to deduce the structure of DNA.s a result, Watson and Crick are largely recognized as discovering the structure of DNA for the first time, but it was really Watson, Crick and Franklin (among other, less influential, work by other scientists).

Table of Contents Astronomers have studied Neptune since September 23, 1846, when Johann Gottfried Galle, of the Berlin Observatory, and Louis d'Arrest, an astronomy student, discovered the eighth planet on the basis of mathematical predictions by Urbain Jean Joseph Le Verrier. Similar predictions were made independently by John Couch Adams.

Big Bang Extrapolation of the expansion of the universe backwards in time using general relativity yields an infinite density and temperature at a finite time in the past. This singularity signals the breakdown of general relativity and thus, all the laws of physics.n 1965, the cosmic microwave background radiation was discovered, which was crucial evidence in favor of the Big Bang model, since that theory predicted the existence of background radiation throughout the universe before it was discovered.

Nuclear fission Nuclear fission of heavy elements was discovered on December 17, 1938 by German Otto Hahn and his assistant Fritz Strassmann, and explained theoretically in January 1939 by Lise Meitner and her nephew Otto Robert Frisch. Frisch named the process by analogy with biological fission of living cells.

Earths Core The solid inner core was discovered by Inge Lehmann, a Danish seismologist, studying p waves traveling through the Earth discovered they increased in speed at a boundary within the Earths core. She published her findings in 1936. The boundary between the inner and outer core is the Lehmann discontinuity.
