Why is Edward Witten famous?

Edward Witten, (born August 26, 1951, Baltimore, Maryland, U.S.), American mathematical physicist who was awarded the Fields Medal in 1990 for his work in superstring theory. He made significant contributions to Morse theory, supersymmetry, and knot theory.

How good is Edward Witten?

In addition to his contributions to physics, Witten’s work has significantly impacted pure mathematics. In 1990, he became the first physicist to be awarded a Fields Medal by the International Mathematical Union, awarded for his 1981 proof of the positive energy theorem in general relativity….

What Dirac proposed?

To cope with this problem, Dirac introduced the hypothesis, known as hole theory, that the vacuum is the many-body quantum state in which all the negative-energy electron eigenstates are occupied. This description of the vacuum as a “sea” of electrons is called the Dirac sea.

What did Stephen Hawking contribute to the field of Physics?

Stephen Hawking is a world-renowned British theoretical physicist, known for his contributions to the fields of cosmology, general relativity and quantum gravity, especially in the context of black holes. In the 1960s and 1970s, he worked on ground-breaking theorems regarding singularities within the framework…

Is Hawking radiation from black holes a theory?

As early as 1974, his theory of the emission of Hawking radiation from black holes was perhaps one of the first ever examples of a theory which synthesized, at least to some extent, quantum mechanics and general relativity

What disease did Stephen Hawking have when he was a student?

Soon after arriving at Cambridge, at the age of 21, Hawking started to develop the first symptoms of amyotrophic lateral sclerosis (ALS or “Lou Gehrig’s disease”), a type of motor neurone disease which would eventually cost him almost all neuromuscular control. Although doctors predicted (incorrectly,…

How did Stephen Hawking achieve commercial success?

Hawking achieved commercial success with several works of popular science in which he discusses his own theories and cosmology in general.
