Richard Feynman: Life and Achievements

Study Notes

Richard Feynman was born in New York to parents of Lithuanian Jewish descent
He demonstrated strong mathematical capabilities at an early age using gadgets to explore mathematical theories
Feynman was refused admission to Columbia University due to quota restrictions, attending MIT instead where he studied mathematics then physics
He received his PhD in quantum mechanics at Princeton, scoring perfectly on his Physics exams

Feynman was appointed a junior physicist in 1943 and worked on the Manhattan Project at Los Alamos
In 1950, he became a professor of theoretical physics at the California Institute of Technology (Caltech)
He received the prestigious Albert Einstein Award in 1954
Known for his engaging lectures, Feynman's Caltech lectures were published in 1964 as the Feynman Lectures on Physics
In 1965, he was awarded the Nobel Prize in Physics (jointly with others) for his work on Quantum Electrodynamics (QED)
He made significant contributions to the understanding of quantum mechanics and physics, revolutionizing the way complex ideas are understood
Notable for introducing Feynman diagrams, a visual representation of quantum processes, simplifying complex equations for particle physics
He played a pivotal role in improving the Quantum Electrodynamics (QED) theory
His work on QED helped to describe the interactions of electromagnetically charged particles, exchange of photons, and other significant mathematical calculations
Despite the initial success of the theory, some mathematical inconsistencies were later noted in the early theories
Feynman's work extended beyond QED, influencing fields like nanotechnology, superfluidity and also explaining the Challenger disaster

Feynman participated in the Manhattan Project from 1942-1945, working on nuclear weapons research
Driven by concern about the possibility of Nazi victory, he joined the research program
He also conducted secret bomb research at Los Alamos National Laboratory and lived in the laboratory's trailer parks
Feynman later taught at Cornell University as a Professor of theoretical physics

Murray Gell-Mann, a polymath and leader in theoretical physics at Los Alamos at the age of 24, accurately described particle interactions to 15 decimal places
He combined his talents in languages abstract thinking, and particle physics to develop a system for classifying subatomic particles
Gell-Mann proposed in 1964 a model for classifying subatomic particles, distinguishing between:
- Fermions: Building blocks of matter.
- Bosons: Force carriers.
He created the term ‘quark’, a hypothetical fundamental unit, now considered a type of fermion, which combine to form hadrons (protons and neutrons)
Later experimental evidence confirmed the existence of quarks, supporting Gell-Mann's model
His model is now known as the "standard model" and was awarded the 1969 Nobel Prize in Physics.

Feynman diagrams, abstract concepts in physics, are visually represented as charming squiggles
Feynman's use of diagrams simplified complex concepts, used for understanding particles in events such as the Large Hadron Collider
His Caltech lectures were popular and used in writing a well-received physics textbook
