Paul Adrian Maurice Dirac, one of the greatest physicists of the twentieth century, died in 1984. His college, St John's College, Cambridge, generously endowed annual lectures to be held at Cambridge University in his memory. This 1990 volume includes an expanded version of the third Dirac Memorial Lecture presented by Abdus Salam.

During the last years of his life Einstein tried unsuccessfully to unify electromagnetic force with gravitational force geometrically. The nearest he got was through the ideas of Kaluza and Klein who appended a tiny fifth commuting coordinate to spacetime. Researchers have followed in those footsteps by adding at least six more such minuscule coordinates so as to incorporate the other forces of nature, culminating in string theory — which has unfortunately not met with experimental support. Other proposals have likewise failed or are still waiting to be confirmed experimentally.The author shows that one can successfully unify gravity with electromagnetism geometrically by adding a single complex anticommuting coordinate to spacetime, which can be associated with the property of 'electricity'. By adding extra four anticommuting properties ('chromicity' and 'neutrinicity'), associated with strong and weak interactions, one can get a unified picture of all the natural forces and particles including the 'standard model': The whole construct relies upon the full specification of events and automatically allows for replication of particle families. The monograph traces the history of attempts of unification before explaining the author's 'where-when-what' scheme.

"For the first time real images of Photon, Electron, Positron, Neutrino, Proton and Neutron are released to World by Super Unified Theory" Super Unified Theory can explain everything, from Classical Physics to Relativity, from Standard Model to God Particle, from Gravitation to Nuclear Force, from Magnetism to Electric fields, from Electromagnetic radiation to Thermodynamics of Universe, from Cosmic Cycle to intricacies of Galactic activities, from structure of Universe to structure of Elementary Particle. "Super unified theory" has answers for everything debated along the centuries in field of physics, astronomy, particle physics and universe. Do you want to know? What is the structure of photon and their process Formation? What is the structure of electromagnetic radiation and how are they produced in Universe? What is the structure electron and site of their electric activity? How particle to wave transformation occurs in Universe? What is the structure of positron, neutrino, proton, and neutron? What are the representatives of magnetic field and electric field lines in at the level of structure of individual particle? Do we have a nuclear configuration representing electron configuration in nucleus? How was Universe before Big Bang? What is the structure of Universe and reason for its expansion? What is the definition of cosmic cycle? What is the origin of all forces and how gravity is applied? Super Unified Theory is major breakthrough in field of physics, particle physics and astronomy with gamut of discoveries ranging from photon structure to structure of Black Hole, From origin, application to unification of all fundamental forces, from structure of Universe to working model of cosmic cycle of creation, destruction and recreation. "A complete Book, which has unified all particles and all forces of Nature, Unbelievable but true because Nature is so simple and straightforward" Regards Abhijit Thakur

Following the discovery of the Higgs boson, Frank Close has produced this major revision to his classic and compelling introduction to the fundamental particles that make up the universe.

#1 NEW YORK TIMES BESTSELLER • The epic story of the greatest quest in all of science—the holy grail of physics that would explain the creation of the universe—from renowned theoretical physicist and author of The Future of the Mind and The Future of Humanity. When Newton discovered the law of gravity, he unified the rules governing the heavens and the Earth. Since then, physicists have been placing new forces into ever-grander theories. But perhaps the ultimate challenge is achieving a monumental synthesis of the two remaining theories—relativity and the quantum theory. This would be the crowning achievement of science, a profound merging of all the forces of nature into one beautiful, magnificent equation to unlock the deepest mysteries in science: What happened before the Big Bang? What lies on the other side of a black hole? Are there other universes and dimensions? Is time travel possible? Why are we here? Kaku also explains the intense controversy swirling around this theory, with Nobel laureates taking opposite sides on this vital question. It is a captivating, gripping story; what’s at stake is nothing less than our conception of the universe. Written with Kaku’s trademark enthusiasm and clarity, this epic and engaging journey is the story of The God Equation.

The Yang-Mills theory of gauge interactions is a prime example of interdisciplinary mathematics and advanced physics. Its historical development is a fascinating window into the ongoing struggle of mankind to understand nature. The discovery of gauge fields and their properties is the most formidable landmark of modern physics. The expression of the gauge field strength as the curvature associated to a given connection, places quantum field theory in the same geometrical footing as the gravitational field of general relativity which is naturally written in geometrical terms. The understanding of such geometrical property may help one day to write a unified field theory starting from symmetry principles. Of course, there are remarkable differences between the standard gauge fields and the gravitational field, which must be understood by mathematicians and physicists before attempting such unification. In particular, it is important to understand why gravitation is not a standard gauge field. This book presents an account of the geometrical properties of gauge field theory, while trying to keep the equilibrium between mathematics and physics. At the end we will introduce a similar approach to the gravitational field.
