Robert Oppenheimer 's interest in poetry: "The aim of science is to make difficult things understandable in a simpler way; the aim of poetry is to state simple things in an incomprehensible way.
Photocopies of manuscripts and letters, and an interview by Thomas S. The work needed in this respect was largely done by Dirac, though not without some promptings from others.

Religion is a kind of opium that allows a nation to lull itself into wishful dreams and so forget the injustices that are being perpetrated against the people. He seemed to have believed that nothing was as important as his physics. And I think that it quite likely that at some future time we may get an improved quantum mechanics in which there will be a return to determinism and which will, therefore, justify the Einstein point of view. Numerous other elementary particles discovered after by experimental physicists were, more often than not, stranger and messier than anything the theorists could have anticipated on the basis of mathematical formulas. After sufficient progress, the field of mathematics would be purified and reduced to applied mathematics, that is, theoretical physics. Dirac offered the first course in quantum mechanics in Britain, entitled Quantum Theory Recent Developments. Antimatter, Monopoles. Like Eddington, Dirac focused on dimensionless numbers built from the fundamental constants of both atomic and cosmic phenomena; and he observed that there was a cluster of these numbers around , including the age of the universe in atomic time units and the ratio of electric forces to gravitational ones inside atoms. Present expositions of quantum mechanics largely rely on his masterpiece The Principles of Quantum Mechanics , and a great part of the basic theoretical framework of modern particle physics originated in his early attempts at combining quanta and relativity. Within six months of arriving in Cambridge he wrote two papers on these problems. In the , he accepted a post as professor of physics at Florida State University, and he continued there until his death in Tallahassee on October 20, While Dirac refused to accept honorary degrees but he accepted membership of academic societies. Dirac is regarded as the founder of quantum electrodynamics , being the first to use that term. But Cunningham had as many students as he was prepared to take and so Dirac started working under the supervision of Ralph Howard Fowler , who had collaborated with Niels Bohr in his pioneering work in atomic physics. Dirac found that what Heisenberg really wanted to achieve consisted in a most general type of operation on a "quantum variable" x which was done by "taking the difference of its Heisenberg products with some other quantum variable.
First comes the magic of projective geometry, exemplifying the power to find surprising relations between picturable mathematical objects through simple, invisible manipulations. He proposed and investigated the concept of a magnetic monopolean object not yet known empirically, as a means of bringing even greater symmetry to James Clerk Maxwell 's equations of electromagnetism.
Dirac was famously not bothered by issues of interpretation in quantum theory. Within a few months he also found the basic commutation and composition rules for angular momentum in multielectron atoms, and he made the first relativistic quantum-mechanical calculation giving the characteristics of Compton scattering.
Paul dirac quotes
He became a fellow of St. Dirac's crucial insight consisted in finding that a very simple operation formed the basis of the formula in question. Although not able to explicate this transformation which presumably would reintroduce infinities. This is in spite of the fact that his favourite subject was mathematics. During and Dirac lectured on the problems of cosmology in the Physical Engineering Institute in Leningrad. He also introduced the idea of vacuum polarisation in the early s. His physics papers and books, however, are literary masterpieces of the genre owing to their absolute perfection in form with regard to mathematical expressions as well as words. It may not be very far away when computers will be developed based on quantum logic. He held this post for 37 years. What had to be done was to calculate the value of the classical Poisson bracket [p, q] for p and q and multiply it by a modified form of Planck's constant. It was plagued with difficulties, in part because of the radical change in the way one thought about the world around us, and in part because it was a difficult problem.
Pauli, raised as a Catholic, had kept silent after some initial remarks, but when finally he was asked for his opinion, said: "Well, our friend Dirac has got a religion and its guiding principle is 'There is no God and Paul Dirac is His prophet.
It is a powerful generalisation of Hamiltonian theory that remains valid for curved spacetime.
Four more papers were completed by November Personal life Early years Paul Adrien Maurice Dirac was born at his parents' home in BristolEngland, on 8 August and grew up in the Bishopston area of the city.
In later life, Dirac would become proverbial for his lack of social and emotional skills and his incapacity for small talk.

All his papers were truly original and contained path-breaking ideas. But one should not suppose that it will survive indefinitely into the future. She had two children Judith and Gabriel Andrew from her first marriage. We simply have to accept it. At the first instance Dirac was contemplating to turn down the Prize on the grounds that he did not relish publicity. It might be that it is so difficult to start life that it has happened only once among all the planets Unfortunately, only half the divergent integrals of quantum electrodynamics were cured by this procedure.
More successfully, he tried to connect it to a Hamiltonian formalism.
