Richard Phillips Feynman (May 11, 1918 - February 15, 1988) last name
pronounced "fine-man", was one of the most influential physicists of the
20th century, expanding greatly the knowledge of quantum electrodynamics. As
well as being an inspiring lecturer and musician, he helped in the
development of the atomic bomb and was later a member of the panel which
investigated the space shuttle Challenger disaster. For his work on quantum
electrodynamics, Feynman was one of the recipients of the Nobel Prize in
Physics for 1965. He is also famous for his many adventures, detailed in the
books Surely You're Joking, Mr Feynman! and What Do You Care What Other
People Think?.
Feynman was born in Far Rockaway, Queens, New York; his parents were Jewish,
although they did not practice Judaism as a religion. The young Feynman was
heavily influenced by his father who encouraged him to ask questions in
order to challenge orthodox thinking. His mother instilled in him a powerful
sense of humour which he kept all his life.
Feynman attended Massachusetts Institute of Technology, before moving on to
Princeton as a graduate. While researching his Ph.D, he married his first
wife, Arlene Greenbaum, who had been diagnosed with tuberculosis, a terminal
illness at that time.
At Princeton, the physicist Robert Wilson encouraged Feynman to participate
in the Manhattan Project--the wartime U.S. Army project at Los Alamos
developing the atomic bomb. He visited his wife in hospital on weekends,
right up until her death in July 1945. Immersing himself in work on the
project, he was present at the Trinity bomb test. Feynman claimed to be the
only person to see the explosion without the dark glasses provided, looking
through a truck windshield to screen out harmful ultraviolet frequencies.
After the project, Feynman started working as a professor at Cornell
University. However he was unhappy there, feeling uninspired. He was
therefore surprised to be offered professorships from competing
universities, eventually choosing to work at the Institute for Advanced
Study at Princeton, which included at that time such distinguished faculty
as Albert Einstein.
Feynman did much of his best work at this time, including research in:
* Quantum electrodynamics. The problem for which Feynman won his Nobel
Prize involved the probability of quantum states changing. He helped
develop a path integral formulation of quantum mechanics, in which
every possible path from one state to the next is considered, the final
path being a sum over the possibilities.
* Physics of the superfluidity of supercooled liquid helium, where helium
seems to display a lack of viscosity when flowing. Applying the
Schrdinger equation to the question showed that the superfluid was
displaying quantum mechanical behaviour which displayed itself on a
large, human interactivable, scale. This helped enormously with the
problem of superconductivity.
* Weak decay, which shows itself in the decay of a neutron into an
electron, a proton, and an anti-neutrino. Later collaborating with
Murray Gell-Mann, the theory was of massive importance, and resulted in
the discovery of a new law of nature (the weak interaction).
He also developed Feynman diagrams, which helped in conceptualising and
calculating of interactions between particles.
From 1950s, Feynman was professor of physics with the California Institute
of Technology (Caltech). At this time he was asked to help in the teaching
of undergraduates. After three years devoted to the task, a series of
lectures was produced, ventually becoming the famous Feynman Lectures on
Physics. Feynman later won the Oersted medal for teaching, which he seemed
especially proud of.
Feynman was a keen and influential popularizer of physics in both his books
and lectures, notably a talk on nanotechnology called Plenty of Room at the
Bottom. He was also one of the first scientists to realise the possibility
of quantum computers. Books written by him include The Character of Physical
Law and QED: The Strange Theory of Light and Matter.
Feynman married twice more, first to Mary Louise Bell of Neodesha, Kansas in
June, 1952, which was unsuccessful and brief, and second to British Gweneth
Howarth, who shared his enthusiasm for life. They remained married for life,
and had a child of their own, Carl, and adopted a daughter, Michelle.
Feynman travelled a lot at this time, notably to Brazil, and schemed to
visit the obscure Russian land of Tuva, a dream that, due to Cold War
bureaucratic problems, never succeeded. During this period he discovered
that he had a form of cancer, but, thanks to surgery, he managed to hold it off.
Feynman was requested to serve on the presidential commission which
investigated the Challenger disaster of 1986. Tactfully fed clues from a
source with inside information, Feynman famously showed on television the
crucial role in the disaster played by the booster's o-ring seals with a
simple demonstration using a glass of ice water and a sample of o-ring
material. His opinion of the cause of the accident differed from the
official findings, and were considerably more critical of the role of
management in sidelining the concerns of engineers. After much petitioning,
Feynman's minority report was included as an appendix to the official document.
The cancer returned in 1987, with Feynman entering hospital a year later.
Complications with surgery worsened his condition, whereupon Feynman decided
to die with dignity and not accept any more treatment. He died on February
15, 1988.

A movie was made about Feynman's life in 1996. Called Infinity and starring
Matthew Broderick, the movie focused on Feynman's relationship with his
first wife, Arlene, with his work on the Manhattan Project serving as a
backdrop for what was essentially a love story. The film received mixed
reviews, however, and did poorly at the box office.
Finally, the character of Feynman was portrayed by Alan Alda in a play
called QED in 2001. The play was essentially a one-man show, with only brief
appearances by other characters, portraying Feynman in his office at Caltech
and covering many of the stories and anecdotes included in Surely You're
Joking, Mr. Feynman! and What Do You Care What Other People Think?
