Study Notes
Murray Gell-Mann
- Gell-Mann was a theoretical physicist who made significant contributions to particle physics.
- In 1964 Gell-Mann proposed a model to classify subatomic particles into fermions and bosons.
- He introduced the concept of quarks as the fundamental units that combine to form hadrons.
- Gell-Mann's model of particle classification became known as the Standard Model and was confirmed by later research.
- He won the Nobel Prize in Physics in 1969 for his work on particle classification.
Richard Feynman
- Feynman Diagrams are abstract representations of physical concepts, used to depict complex ideas.
- Feynman's work greatly advanced our understanding of quantum electrodynamics (QED).
- Feynman diagrams represent the movements of particles like electrons and photons in both time and space.
- His diagrams allowed calculations of probabilities of particle events, leading to more accurate predictions and results.
- Feynman's work extended into related areas of physics, including nanotechnology, superfluidity, and quantum computing.
- Feynman was involved in the investigation of the Challenger space shuttle disaster, demonstrating the cause through simple physics experiments.
Milestones in Feynman's Life
- Feynman was a junior physicist in the Manhattan Project at Los Alamos, New Mexico, in 1943.
- In 1950, he became a professor of theoretical physics at the California Institute of Technology (Caltech).
- In 1954, Feynman received the Albert Einstein Award.
- In 1964, Feynman's lectures at Caltech were published as the Feynman Lectures on Physics.
- In 1965, Feynman was awarded the Nobel Prize in Physics for his work on QED.
