Richard Feynman is considered to be one of the most miraculous personalities in scientific history. The 1965 Nobel prize winner on QED (along with J. Schwinger and Tomonaga), Dr. Feynman was a remarkably amazing educator and a great physicist. Feynman, along with many other contributions to science, had created a mathematical theory that accounts for the phenomenon of superfluidity in liquid helium. Thereafter, he had fundamental contributions (along with Murray Gell-Mann) to weak interactions such as beta decay. In his later years, Feynman played a significant role in the development of quark theory by putting forward his Parton model of high energy proton collision processes. He also introduced basic new computational techniques and notations into physics. Besides being a physicist, he was at various times repairer of radios, a picker of locks, an artist, a dancer, a bongo player, a great teacher, and a showman who successfully demonstrated the cause of the 1986 Challenger Shuttle Disaster as part of the Roger’s Commission.
The genius of Richard Feynman in evident from his three-volume books on physics called The Feynman Lectures on Physics, which are based on his lectures at Caltech during 1961–1963.
In his teenage years, Richard Feynman’s high school did not offer any courses on calculus. As a high-school teenager, he decided to teach himself calculus and read Calculus for the Practical Man.

Feynman always believed that if one cannot explain something in simple terms, one doesn’t understand it. A similar quotation is attributed to Albert Einstein as well. Whether or not it originally comes from Feynman, the idea is elegantly true and is, in fact, the basis for the Feynman technique of learning things. Feynman is often attributed as The Great Explainer for his ability to explain complicated concepts in science, particularly physics, in extremely simple and understandable manner, in a way that in people from a non-scientific background could understand.
