Richard Phillips Feynman (/ ˈ f aɪ n m ə n /; May 11, 1918 – February 15, 1988) was an American theoretical physicist.He is best known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, and in particle physics, for which he proposed the parton model.
Cecilia Payne-Gaposchkin (born Cecilia Helena Payne; () May 10, 1900 – () December 7, 1979) was a British-American astronomer and astrophysicist.In her 1925 doctoral thesis she proposed that stars were composed primarily of hydrogen and helium.
On December 1, 2009, he began hosting a 12-episode weekly television series for the Science Channel at 10 pm, called Sci Fi Science: Physics of the Impossible, based on the book of the same name. Each 30-minute episode discusses the scientific basis behind imaginative schemes, such as time travel, parallel universes, warp drive, and similar.
By Aug 1st 2018 the paper has been quoted in 153 physics papers, including by well-known physicists such as Lee Smolin, and Mordehai Milgrom - originator of MOND. Explanation of modified gravity through entropic gravity is a "quantum gravity theory" merging "general theory of relativity" with "quantum field theory".
These versions are known as type I, type IIA, type IIB, and the two flavors of heterotic string theory (SO(32) and E 8 ×E 8). The thinking was that of these five candidate theories, only one was the actual correct theory of everything, and that theory was the one whose low-energy limit matched the physics observed in our world today.

The blog is called Backreaction and it is run by both Hossenfelder and her husband Stefan Scherer who is also a physicist. [12] She contributed to the Forbes column "Starts with a Bang" [13] and to The Guardian [14] [15] as well as Quanta Magazine, [16] New Scientist, [17] Nature Physics, [18] Scientific American, [19] Nautilus Quarterly, [20 ...
At present, Griffiths is the Otto Stern University Professor of Physics at Carnegie Mellon University. He has published over 140 articles, as well as the book Consistent Quantum Theory. [2] He is a member of Sigma Xi, a Fellow of the American Physical Society and a Fellow of the American Scientific Affiliation. Griffiths's research interests ...
Brian Randolph Greene [1] (born February 9, 1963) is an American physicist known for his research on string theory.He is a professor of physics and mathematics at Columbia University, director of its center for theoretical physics, and the chairman of the World Science Festival, which he co-founded in 2008.
