Biographical timeline of English theoretical physicist Paul Dirac, who formulated the Dirac Equation predicting antimatter, spanning his birth in Bristol to his death in Tallahassee, with key milestones including his education, major publications, Nobel Prize, and later years at Florida State University.
Paul Adrien Maurice Dirac is born in Bishopston, Bristol, England, to Charles Dirac and Florence Hannah Holten. His father was a Swiss immigrant and his mother was English. #physics #birth
Dirac begins his secondary education at the Merchant Venturers' Technical College (later Cotham School), where he excels in mathematics and science. #education
Dirac enrolls at the University of Bristol to study electrical engineering, graduating with a B.Sc. in 1921. This training influenced his later precision in theoretical physics. #engineering #education
After struggling to find employment, Dirac takes a second degree in mathematics at the University of Bristol, funded by a scholarship. #education
Dirac graduates with a first-class honours degree in electrical engineering from the University of Bristol. Unable to find a suitable engineering job, he pursues further studies. #education
Dirac graduates with another first-class honours degree in mathematics from the University of Bristol. He then wins a scholarship to study at St John's College, Cambridge. #education
Dirac begins his PhD at St John's College, Cambridge, under the supervision of Ralph Fowler. He immersed himself in the emerging field of quantum mechanics. #physics #education
Inspired by a paper from Werner Heisenberg, Dirac develops an elegant mathematical formalism for quantum mechanics, leading to his first major paper 'The Fundamental Equations of Quantum Mechanics'. #quantum #physics
Dirac publishes his transformation theory, a generalization of quantum mechanics that includes the bra–ket notation. This formalism remains standard in quantum mechanics. #quantum #math
Dirac receives his PhD from the University of Cambridge for his thesis 'Quantum Mechanics'. His work already establishes him as a leading figure in the field. #physics #education
Dirac publishes a paper on quantum electrodynamics, laying the groundwork for the theory of radiation. #physics #QED
Dirac travels to Göttingen and Copenhagen to work with leading physicists like Max Born and Niels Bohr. These collaborations enrich his understanding of quantum mechanics. #physics #travel
Dirac is elected a fellow of St John's College, Cambridge. This position provides him with financial stability to continue his research. #academia
Dirac publishes his relativistic wave equation for the electron, now known as the Dirac Equation. This equation naturally incorporates spin and predicts the existence of antimatter. #antimatter #equation
At age 27, Dirac is elected a Fellow of the Royal Society (FRS), one of the youngest ever. #award #honor
Dirac's classic textbook 'The Principles of Quantum Mechanics' is published. It remains a definitive text and introduced the bra–ket notation. #book #quantum
Dirac proposes the existence of the positron, the antimatter counterpart of the electron, based on his equation. This prediction is confirmed experimentally in 1932. #antimatter #prediction
Dirac is appointed Lucasian Professor of Mathematics at Cambridge University, a position once held by Isaac Newton. He holds this chair until 1969. #academia #professorship
Dirac shares the Nobel Prize in Physics with Erwin Schrödinger for the discovery of new productive forms of atomic theory. Dirac's equation is central to the award. #Nobel #physics
Dirac marries Margit Wigner, sister of physicist Eugene Wigner. They have two children, Mary and Gabriel. #personal #marriage
Dirac publishes a classical theory of the electron, attempting to solve problems of self-energy. #physics #electrodynamics
Dirac speculates on the large numbers hypothesis, suggesting fundamental constants are related to cosmological quantities. #cosmology #physics
