Charon (moon) Charon's discovery as a time-varying bulge on the image of Pluto (seen near the top at left, but absent on the right) Charon was discovered by U.S.
Naval Observatory astronomer James Christy, using the 1.55-meter telescope at NOFS,[9] and was formally announced to the world via the International Astronomical Union on July 7, 1978.[10] On June 22, 1978, he had been examining highly magnified images of Pluto on photographic plates taken at the 61-inch Flagstaff telescope two months prior. Christy noticed that a slight elongation appeared periodically. Later, the bulge was confirmed on plates dating back to April 29, 1965.

Strange matter. 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. Zenith. Diagram showing the relationship between the zenith, the nadir, and different types of horizon.
Note that the zenith is opposite the nadir. The zenith is an imaginary point directly "above" a particular location, on the imaginary celestial sphere. "Above" means in the vertical direction opposite to the apparent gravitational force at that location. The opposite direction, i.e. the direction in which gravity pulls, is toward the nadir.
Zenith may be used as a name which means success and power. Origin[edit] Weierstrass function. A differentiable function Differentiable functions can be locally approximated by linear functions.
More generally, if x0 is a point in the domain of a function f, then f is said to be differentiable at x0 if the derivative f′(x0) exists. This means that the graph of f has a non-vertical tangent line at the point (x0, f(x0)). The function f may also be called locally linear at x0, as it can be well approximated by a linear function near this point. Differentiability and continuity[edit] Aren't There Really 11 Dimensions? Stephen Hawking. English theoretical physicist, cosmologist, and author Stephen William Hawking CH CBE FRS FRSA (8 January 1942 – 14 March 2018) was an English theoretical physicist, cosmologist, and author who was director of research at the Centre for Theoretical Cosmology at the University of Cambridge at the time of his death.[18][19][8] He was the Lucasian Professor of Mathematics at the University of Cambridge between 1979 and 2009.
Hawking was born in Oxford, into a family of doctors. He began his university education at University College, Oxford, in October 1959 at the age of 17, where he received a first-class BA degree in physics. He began his graduate work at Trinity Hall, Cambridge, in October 1962, where he obtained his PhD degree in applied mathematics and theoretical physics, specialising in general relativity and cosmology in March 1966.
Hawking achieved commercial success with several works of popular science in which he discussed his theories and cosmology in general. Early life Family. Edward Witten. Edward Witten (/ˈwɪtən/; born August 26, 1951) is an American theoretical physicist and professor of mathematical physics at the Institute for Advanced Study in Princeton, New Jersey.
Witten is a researcher in string theory, quantum gravity, supersymmetric quantum field theories, and other areas of mathematical physics. Birth and education[edit] Witten was born in Baltimore, Maryland. He is the son of Lorraine (Wollach) Witten and Louis Witten, a theoretical physicist specializing in gravitation and general relativity.[3] Witten attended the Park School of Baltimore (class of '68), and received his Bachelor of Arts with a major in history and minor in linguistics from Brandeis University in 1971.
Research[edit] Fields medal work[edit] 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.
A fost introdusă în 1918 de către Felix Hausdorff și dezvoltată ulterior de către Abram Samoilovici Bezicovici, de unde și denumirea de dimensiune Hausdorff-Bezicovici. Fractal. Figure 1a.
The Mandelbrot set illustrates self-similarity. As the image is enlarged, the same pattern re-appears so that it is virtually impossible to determine the scale being examined. Figure 1b. The same fractal magnified six times. Figure 1c. Figure 1d. Fractals are distinguished from regular geometric figures by their fractal dimensional scaling. As mathematical equations, fractals are usually nowhere differentiable.[2][5][8] An infinite fractal curve can be conceived of as winding through space differently from an ordinary line, still being a 1-dimensional line yet having a fractal dimension indicating it also resembles a surface.[7]:48[2]:15.

A direct link to the above video is at Poll 23 - "Why is it impossible to exceed the speed of light? Because our universe is being created one planck length at a time, at the speed of light. " Poll ended September 20th, 2008. 66% agreed while the rest disagreed. I wonder if some people disagreed with the above statement because of my choice of the word "created": terms like this can be confusing when the universe we're imagining is really just being observed one planck length after another from out of a wave function of probably outcomes.
As Everett's Many Worlds Interpretation has it, and as this project also has it, the other possible universes continue to exist out there within timelessness, they're just not the version that we're observing at this "now" within spacetime.
