Twentieth-century physics is often defined by a pair of powerful and powerful scientists of nature. That is, theories such as theory of general relativity and Quantum Mechanics that were brought to the world in the years 1915 and 1925, but between these years in 1918 came another great scientist who was able to single-handedly define twentieth-century physics. Was. Whose name is Richard Feynman.

Richard Feynman was an American Theoretical Physicist, widely regarded as the most brilliant and influential figure in physics in the post World War II era. Richard Feynman remade Quantum electrodynamics* (Quantum electrodynamics is called the interaction between light and matter)*.

Apart from this, Feynman is known for his work in path integral formulation, quantum mechanics, physics of supercooled liquid helium and physics of particle physics. Feynman was awarded the Nobel Prize in Physics in 1965, jointly with Julian Schwinger and Shinichiro Tomonaga, for their contribution to the development of quantum electrodynamics.

## Early life of Richard Feynman

Born in Far Rockaway, New York City, Richard Feynman was a descendant of Russian and Polish Jews who immigrated to the United States in the 19th century. Financially, his family was neither rich nor poor, meaning he lived a comfortable life but was not rich.

### Richard Feynman’s parents

Lucille Phillips was the parent of Richard Feynman, a homemaker and Melville Arthur Feynman, a sales manager. Like Albert Einstein and Edward Taylor, Feynman was also a late talker. The young Richard was heavily influenced by his father, who encouraged Richard to challenge orthodox thinking and to always ask questions, and who was always ready to teach Richard something new.

### Childhood of Richard Feynman

Richard Feynman inherited the sense of sense of humor from his mother. Young Richard was interested in engineering, although his parents were happy with it, but wanted to make Richard a scientist. Richard’s younger brother died at the age of 4 weeks on 25 February 1924. At the time Richard was only 5 years old 4 years later Richard’s sister Joan was born and the family moved to Far Rockaway, Queens.

Joan and Richard both had similar thoughts because they both had a curiosity to learn about the universe and nature, even after their mother’s disapproval of Joan’s desire to study astronomy, Richard told his sister to know the universe And thus became an astrophysicist, specializing in the interactions between Earth and Solar Wind after the sister of Recharge grew up.

### Richard Feynman’s Education

At the age of 15, Richard Feynman took over Trigonometry, Advance algebra, Infinite Series, Analytic Geometry, Differential and Integral Calculus. Before entering college, Richard experimented on mathematical topics to create various mathematical notations and special symbols to make it easier to identify logarithm, sine, cosine, and tangent functions.

The young Richard had mastered Mathematics, and it was for this reason that he won the Youth University Mathematics Championship. Richard studied physics at the University of Massachusetts Institute of Technology, where he proposed a basic and sustainable approach to calculating forces between molecules.

Richard Feynman received his doctorate in 1942 from Princeton University. He developed an approach to quantum mechanics with John Wheeler, Richard’s advisor at Princeton. This approach completely changed the wave oriented electromagnetic picture developed by James Clerk Maxwell to particle interactions mapped in space and time. In fact, Richard’s method calculated the probability of all possible positions of a particle from one point to another.

## Richard Feynman’s Career and Research

During World War II Richard Feynman was made a staff member in the American Atomic bomb project at Princeton University and then a staff member at the secret laboratory in Los Alamos, New Mexico, the lowest in the theoretical division of the Richard Manhattan Project in Los Alamos He became a group leader of the age with Hans Bethe, the head of that division. He prepared a formula to know the energy yield of nuclear explosives.

Richard Feynman used new machines for calculating huge amounts of numerical computation in the Manhattan Project. After completing all the tests, he saw the first test explosion of an atomic bomb near New Mexico on 16 July 1945. Although his initial reaction was very encouraging, he later expressed concern and thought about the force of the atomic bomb, which he and his colleagues together succeeded in how dangerous it could prove to be for the world.

### After the end of World War II

Richard Feynman became an associate professor at Cornell University after the end of World War II and continued his study on quantum electrodynamics. By 1948 Richard solved the meaningless theory of old electrodynamics by completing quantum mechanics and quantum electrodynamics,

He introduced simple diagrams which are now known as feynman diagrams. In 1950 he remained a professor of theoretical physics at the California Institute of Technology (Caltech), Richard’s speeches at Caltech developed into quantum electrodynamics and the theory of fundamental processes.

In 1961 he began to reconstruct and teach the early physics textbook at Caltech, his lecture in Caltech published as The Feynman Lectures which became a classic text book for his contribution to the development of quantum electrodynamics and Julian Schwinger Richard Feynman was awarded the 1965 Nobel Prize in Physics. Richard Feynman was also elected a member of the Royal Society and was awarded the 1979 national medal.

## The death

Richard Feynman died in 1968 after a long struggle with cancer. He gained a popular fame. His special achievements have made an important contribution to the development of modern physics.
