Charon (moon)
Charon is the largest satellite of the dwarf planet Pluto . It was discovered in 1978 at the United States Naval Observatory Flagstaff Station (NOFS). Following the 2005 discovery of two other natural satellites of Pluto ( Nix and Hydra ), in 2011, a fourth, S/2011 P 1 , and on July 11, 2012, a fifth satellite S/2012 P 1 , Charon may also be referred to as (134340) Pluto I . [ 1 ] The New Horizons mission is scheduled to visit Charon and Pluto in July 2015.

Strange matter is a particular form of quark matter , usually thought of as a "liquid" of up , down , and strange quarks . It is to be contrasted with nuclear matter , which is a liquid of neutrons and protons (which themselves are built out of up and down quarks), and with non-strange quark matter, which is a quark liquid containing only up and down quarks. At high enough density, strange matter is expected to be color superconducting .

Stephen Hawking
Stephen William Hawking , CH , CBE , FRS , FRSA (born 8 January 1942) is a British theoretical physicist , cosmologist , and author. Among his significant scientific works have been a collaboration with Roger Penrose on gravitational singularities theorems in the framework of general relativity , and the theoretical prediction that black holes emit radiation, often called Hawking radiation . Hawking was the first to set forth a cosmology explained by a union of the general theory of relativity and quantum mechanics . He is a vocal supporter of the many-worlds interpretation of quantum mechanics. He is an Honorary Fellow of the Royal Society of Arts , a lifetime member of the Pontifical Academy of Sciences , and a recipient of the Presidential Medal of Freedom , the highest civilian award in the United States.
Edward Witten (born August 26, 1951) is an American theoretical physicist with a focus on mathematical physics who is a professor of mathematical physics at the Institute for Advanced Study , in Princeton, New Jersey. Witten is a researcher in superstring theory , a theory of quantum gravity , supersymmetric quantum field theories and other areas of mathematical physics. [ 1 ] He has made contributions in mathematics and helped bridge gaps between fundamental physics and other areas of mathematics.

Dimensiune Hausdorff
În cadrul topologiei , dimensiunea Hausdorff este un număr real pozitiv, asociat unui spațiu metric și extinde noțiunea de dimensiune a unui spațiu vectorial real.Fractal
Figure 1a. The Mandelbrot set illustrates self-similarity. As you zoom in on the image at finer and finer scales, the same pattern re-appears so that it is virtually impossible to know at which level you are looking. Figure 1b.
