Leonard Susskind (born June, 1940) is the professor of theoretical physics at Stanford University, and director of the Stanford Institute for Theoretical Physics. His research interests include string theory, quantum field theory,quantum statistical mechanics and quantum cosmology He is a member of the National Academy of Sciences of the US, and the American Academy of Arts and Sciences, an associate member of the faculty of Canada's Perimeter Institute for Theoretical Physics, and a distinguished professor of the Korea Institute for Advanced Study.
Susskind is widely regarded as one of the fathers of string theory, having, with Yoichiro Nambu and Holger Bech Nielsen, independently introduced the idea that particles could in fact be states of excitation of a relativistic string.He was the first to give a precise string-theory interpretation of the holographic principle in 1995, and the first to introduce the idea of the string theory landscape in 2003 .Susskind was awarded the 1998 J. J. Sakurai Prize .
* To day i want to talk about his famous idea and theory it's about the hologram :
Leonard susskind He did not like the words of Stephen Hawking's black holes, and specifically for the loss of information inside the black hole, and explained that this important breakthrough forthe law, which save the information law. Sescand triumphed in the end, as a result of thecontroversy rages, the theory of principle Alholograma proposed by Gerard Hooftemerged. Susskind is one of the largest contributors to the string theory, which gave a new concept for scientists' understanding of the universe and the particles and quantum physics.
Holography principle (in English: holographic principle) is one of the special theory of tendons and principles and the principle also possible with regard to quantum gravity, which is trying to resolve the paradox of the black hole information through string theory.This principle provides for the characterization of a given volume of space through the coding of its information on the full limits (preferably choosing somewhat similar-light [note 1] such as the horizon gravitational limit) and for black hole mention this principle that describe an object fell into this hole lies in surface fluctuations of the black hole horizon happened. The first to suggest that this principle is a theoretical physicist Gerard died, he got this principle is an accurate interpretation of using string theory done by Leonard Ssowskaand [1] [2] [3] where the integration of his thoughts on this principle with the findings of both died and Charles Thorne. Rafael Poso has pointed out that Thorne has been observed since 1978 that string theory provides a description based on a smaller number of dimensions and show the gravity including label can be a way Hologravea.
The sense of a more general principle Holography is assumed that it is possible to look at the entire universe Kpnip of bi-dimensional information "painted" on the cosmic horizon, so that the holographic images that we see now are just a drop too amplifier such information enjoys being a power very low in comparison with her. Until now it has not been described holography cosmic mathematical equations minute due in part to that in the cosmic horizon limited space to grow with the passage of time.Holography was inspired by the principle of the thermodynamics of black holes, which suggest the presence of fit between the entropy of Adhamiya in space with the radius of the square space (not with cubed radius, as is expected). Where the principle of Alholograveh suggests the existence of similar suits in the case of the black hole so that the informational content (in other words, entropy) own all objects that fell into the black hole that symbolizes the entire horizon across the surface of the vagaries of the special event black hole. Holography principle resolves the paradox of the black hole information within the framework of string theory. Nevertheless, there are a range of classical solutions to Einstein's equations allow for entropy to take values higher than those allowed by the law of the surface and thus higher than those of black holes. These solutions are called "gold-filled Wheeler Bags". These solutions are incompatible with the proposed interpretation Holography and so far no one has come to understand the effects of these solutions accurately on the quantum theory of gravitation, including the principle Holography .
