Richard Phillips Feynman (/ ˈ f aɪ n m ə n /; May 11, 1918 – February 15, 1988) was an American theoretical physicist.He is best known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, and in particle physics, for which he proposed the parton model.
[4] [5] The classic particle physics text Aspects of Symmetry (1985) is a collection of Coleman's lectures at Erice. A quote from his introduction to the book is worth sharing here: [6] I first came to Erice in 1966, to lecture at the fourth of the annual schools on subnuclear physics organized by Nino Zichichi.
Helen Rhoda Arnold Quinn (born 19 May 1943) is an Australian-born particle physicist and educator who has made major contributions to both fields. Her contributions to theoretical physics include the Peccei–Quinn theory which implies a corresponding symmetry of nature [2] [3] (related to matter-antimatter symmetry and the possible source of the dark matter that pervades the universe) and ...
Also, in this chapter Dr. Lederman gives a brief background story of what led him to particle physics. [12] Chapter 2: The First Particle Physicist: In a fictional dream, Dr. Lederman meets Democritus, an ancient Greek philosopher who lived during the Classical Greek Civilization, and has a conversation (a Socratic dialogue) with him.

Anderson was born in New York City, the son of Swedish immigrants.He studied physics and engineering at Caltech (B.S., 1927; Ph.D., 1930).Under the supervision of Robert A. Millikan, he began investigations into cosmic rays during the course of which he encountered unexpected particle tracks in his (modern versions now commonly referred to as an Anderson) cloud chamber photographs that he ...
Particle physics or high-energy physics is the study of fundamental particles and forces that constitute matter and radiation. The field also studies combinations of elementary particles up to the scale of protons and neutrons , while the study of combination of protons and neutrons is called nuclear physics .
In 1976, Ting was awarded the Nobel Prize in Physics, which he shared with Burton Richter of the Stanford Linear Accelerator Center, for the discovery of the J/ψ meson nuclear particle. They were chosen for the award, in the words of the Nobel committee, "for their pioneering work in the discovery of a heavy elementary particle of a new kind."
The Standard Model of particle physics is the theory describing three of the four known fundamental forces (electromagnetic, weak and strong interactions – excluding gravity) in the universe and classifying all known elementary particles.
