What Is Physics By Dr.Richard Feynman.

The article contains a description of physics by one of the greatest physicists Dr. Richard Feynman. Read to know and understand why laws of physics go on changing. In order to know the definition of physics according to Richard Feynman, first we have to look at who Richard Feynman was ?

Who Was Richard Feynman ?

Richard Phillips Feynman (born May 11, 1918, New York, U.S, died February 15, 1988, Los Angeles, California) was one of the greatest physicists of the 20th century, his contribution in the development of quantum electrodynamics led him to receive the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin’ichirō Tomonaga.

He also contributed in the physics of the superfluidity of supercooled liquid helium, as well as his work in particle physics for which he proposed the parton model. He is also known for his contributions in nanotechnology, Feynman checkerboard, Feynman Diagrams, Feynman Point, One-electron universe, The Feynman Lectures of Physics.

Example of Chess Game :

Physics Compare to Chess

The great physicist Dr R. P. Feynman has given a wonderful description of what is “understanding nature”. Suppose we do not know the rules of chess but are allowed to watch the moves of the players. If we watch the game for a long time, we may make out some of the rules. With the knowledge of these rules we may try to understand why a player played a particular move. However, this may be a very difficult task.

Even if we know all the rules of chess, it is not so simple to understand all the complications of a game in a given situation and predict the correct move. Knowing the basic rules is, however, the minimum requirement if any progress is to be made.

One may guess at a wrong rule by partially watching the game. The experienced player may make use of a rule for the first time and the observer of the game may get surprised. Because of the new move some of the rules guessed at may prove to be wrong and the observer will frame new rules.


Physics goes the same way. The nature around us is like a big chess game played by Nature. The events in nature are like the moves of the great game. We are allowed to watch the events of nature and guess at the basic rules according to which the events take place. We may come across new events which do not follow the rules guessed earlier and we may have to declare the old rules inapplicable or wrong and discover new rules.

Since physics is the study of nature, it is real. No one has been given the authority to frame the rules of physics. We only discover the rules that operate in nature.
