Richard Feynman was an American physicist who lived between 1918-1988. He is famous for his contributions in building the first nuclear bomb and for his work in understanding the way electrons behave.
He also developed safer methods for the storage of nuclear wastes and solved the mystery behind the space shuttle Challenger's explosion
He contributed to many areas of physics, including atomic theory and quantum electrodynamics, which studies electron behavior
Following his college education, Feynman was asked to participate in the Manhattan Project, the building of the first atomic bomb. He later developed safer methods for the storage of radioactive waste and saved the lives of workers at many nuclear power plants.
In 1986, Feynman was appointed to the committee investigating the explosion of the space shuttle Challenger. He identified the problem as resulting from faulty equipment rather than astronaut error.
