On this day 123 years ago, on August 8, 1902 (July 5, 1902 lunar calendar), British physicist Paul Dirac was born. Paul Dirac Dirac (PaulAdrieMauriceDirac, August 8, 1902 - October 20, 1984), British theoretical physicist, one of the founders of quantum mechanics, won the 1933 Nobel Prize for Dirac's equation. Dirac was born in Bristol, southwest England. He obtained two degrees in electrical engineering and mathematics at the University of Bristol, and a doctorate at Cambridge University in 1926. His main contributions to physics are: the formulation of the quantum mechanical equations (Dirac's equations) describing relativistic Fermi particles, the antiparticle solution; the prediction of magnetic monopoles; and Fermi-Dirac statistics. In addition, he also made foundational work in quantum field theory, especially quantum electrodynamics. He also made outstanding work in the theory of attractive forces and the quantization of attractive forces. He wrote many books throughout his life. His Principles of Quantum Mechanics has always been the authoritative classic work in the field, and some people even call it "the Bible of Quantum Mechanics". Dirac (1902-1984) was a British physicist. Born in Bristol, England on August 8, 1902. Dirac attended secondary school in vocational schools. After graduating in 1918, he was admitted to the Department of Electrical Engineering at the University of Bristol. He graduated from university in 1921 with a bachelor's degree in electrical engineering. In 1923, he was admitted to St. John's College, Cambridge University as a graduate student in mathematics. In 1925, he began to study quantum mechanics founded by Heisenberg and others. In 1926, he published a thesis entitled "Quantum Mechanics" and received a doctorate in physics from the University of Cambridge. He was invited to be a researcher at St. John's College. In 1929, he traveled around the world for academic visits. He first stayed in the United States for five months. Later, he visited Japan with Heisenberg, and then traveled across Siberia and returned to England. In 1930, he was elected a member of the Royal Society of London. From 1932 to 1969, Dirac was He has also served as a visiting professor at the University of Wisconsin, the University of Michigan, Princeton University, the University of Miami and other famous universities. In 1933 Dirac and Schrödinger shared the Nobel Prize in Physics. Since 1971, he has been an honorary professor at Cambridge University and a professor of physics at Florida State University. He died on October 24, 1984. He was 82 years old. Comments: Dirac equation, founder of quantum radiation theory.
