what is stephen hawkings famous for?

Answer 1

Stephen Hawking is most famous for his "String Theory." However he has made other contributions to theoretical physics. He is one of my favorite scientists of this decade, although, many people consider "String Theory" a philosophy more than a science because it has no possible way of being proven.

Answer 2

Stephen William Hawking CH, CBE, FRS, is considered one of the world's leading theoretical physicists. Hawking is the Lucasian Professor of mathematics at the University of Cambridge (a post once held by Sir Isaac Newton), and a Fellow of Gonville and Caius College, Cambridge.

Hawking's principal fields of research are theoretical cosmology and quantum gravity. In 1971, in collaboration with Sir Roger Penrose, he proved the first of many singularity theorems; such theorems provide a set of sufficient conditions for the existence of a singularity in space-time. This work showed that, far from being mathematical curiosities which appear only in special cases, singularities are a fairly generic feature of general relativity.

Hawking also suggested that, after the Big Bang, primordial or mini black holes were formed. With Bardeen and Carter, he proposed the four Laws of black hole mechanics, drawing an analogy with thermodynamics. In 1974, he calculated that black holes should thermally create and emit subatomic particles, known as Hawking radiation, until they exhaust their energy and evaporate.

In collaboration with Jim Hartle, Hawking developed a model in which the Universe had no boundary in space-time, replacing the initial singularity of the classical Big Bang models with a region akin to the North pole; while one cannot travel North of the North pole, there is no boundary there. While originally the no-boundary proposal predicted a closed Universe, discussions with Neil Turok led to the realization that the no-boundary proposal is consistent with a Universe which is not closed also.

Stephen William Hawking is considered one of the world's leading theoretical physicists. Hawking is the Lucasian Professor of mathematics at the University of Cambridge (a post once held by Sir Isaac Newton), and a Fellow of Gonville and Caius College, Cambridge.

Despite enduring severe disability and, of late, being rendered quadriplegic by motor neurone disease (specifically, amyotrophic lateral sclerosis, also called Lou Gehrig's disease), he has had a successful career for many years, and has achieved status as an academic celebrity.

Stephen's belief that the average person should have access to his work led him to write a series of popular science books in addition to his academic work. The first of these, A Brief History of Time, was published on April 1, 1988, and became a documentary in 1991 starring Hawking, his family and friends, and some leading physicists. It surprisingly became a best-seller, and was followed by The Universe in a Nutshell (2001).

Both books have remained highly popular all over the world. A collection of essays, Black Holes and Baby Universes (1993) was also popular. He has now written a new book, A Briefer History of Time (2005) that aims to update his earlier works and make them more accessible to a wider audience. He has recently announced that he plans to write a children's book focusing on science that has been described to be "like Harry Potter, but without the magic."

Hawking is an active supporter of various causes. He appeared on a political broadcast for the United Kingdom's Labour Party, and actively supports the children's charity, SOS Children's Villages UK

He recently made the news for announcing that he believes colonization on other planets and/or the moon is imperative to ensure the continuation of the human race.

Answer 4

Hawking is famous for his work on black holes. His work relating to black holes can be read about in his books, A Brief History of Time, and The Universe in a Nutshell.

Answer 5

He try to find God in physics.
=================
Can we using formulas to know anything about the God ?
Can we using formulas and equations of physics
to know anything about the God ?
Is it possible to explain religion with the help of the
physical and mathematical theorems?
Yes. It is possible.
Because creating all MATERIAL WORLD the God
could only working in an absolute reference system
and only under physical and mathematical laws.
========================
1.
What is the absolute reference system?
=============
Now it is consider, that reference frame connected with
relict isotropic radiation T = 2,7K is absolute.
But T = 2,7K is not a constant factor.
This relict isotropic radiation continues to extend and decrease
and, hence, approximately over a period of
20 billions years will reach T=0K.
That is a structure of Nothing, of Vacuum, of Absolute Zero.
Absolute God can exist only behind this
Absolute reference system : Vacuum T=0K.
2.
The Quantum physics approves, that in the beginning
God /Vacuum created " virtual particles ".
What a geometrical and physical parameters can the particles have in
the structure of Nothing, in Vacuum, in Absolute Zero in T=0K?
=========
According to the laws of physics :
J. Charles ( 1787), Gay-Lussac ( 1802),
W. Nernst ( 1910), A. Einstein ( 1925)
particles in a Vacuum cannot have density, volume
and consequently should be flat figures.
===================
These laws tell, that
then closer to zero T=0K, then the particles lose more their volume.
The volume of these particles aspire to infinity.
And then this “ infinity” comes the brain of physicists
stop to work. They refuse to think any more.
And I say when volume of the particles disappear they
become “flat phantoms”.
These “flat phantoms” are not abstract particles, they are real ones.
Quantums of light flies with speed c=1 have such geometrical form.
=========================
2.
What is a quantum of light?
From all particles, only and only
the quantum of light is a privileged particle.
Only a light quantum has the absolute speed c=1.
==================
The secret of God and Existence is hiding
in the “ Theory of light quanta”.

Answer 8

He is the most famous physicist because he sits at the post once held by Isaac Hayes.

Answer 9

quantum theory, "A Brief History of Time", every famous in physics since Einstein

Answer 10

Only person to guest star on both the Simpsons AND Family Guy.

Other than that he is a big nothing...a black hole...or some other negative sciency type term.
