INTRODUCTION TO SUPERSTRINGS MICHIO KAKU PDF

The question which divides us is whether it is crazy enough. Niels Bohr Superstring theory has emerged as the most promising candidate for a quan tum theory of all known interactions. Superstrings apparently solve a problem that has defied solution for the past 50 years, namely the unification of the two great fundamental physical theories of the century, quantum field theory and general relativity. Superstring theory introduces an entirely new physical picture into theoretical physics and a new mathematics that has startled even the mathematicians. Ironically, although superstring theory is supposed to provide a unified field theory of the universe, the theory itself often seems like a confused jumble offolklore, random rules of thumb, and intuition. This is because the develop ment of superstring theory has been unlike that of any other theory, such as general relativity, which began with a geometry and an action and later evolved into a quantum theory.

Kaku defines the show as dealing with the general topics of science, war, peace and the environment. Featured guests include Nobel laureates and top researchers in the fields of string theory, time travel, black holes, gene therapy, aging, space travel, artificial intelligence and SETI. When Kaku is busy filming for television, Science Fantastic goes on hiatus, sometimes for several months. Kaku is also a frequent guest on many programs, where he is outspoken in all areas and issues he considers of importance, such as the program Coast to Coast AM where, on November 30, , he reaffirmed his belief that the existence of extraterrestrial life is a certainty.

Kaku has appeared on many mainstream talk shows, discussing popular fiction such as Back to the Future , Lost , and the theories behind the time travel these and other fictional entertainment focus on. It played theatrically in the United States, was later broadcast on national TV, and won several film awards. It screened at the Montreal World Film Festival; a feature film expansion is in development talks. Kaku also appeared in the ABC documentary UFOs: Seeing Is Believing , in which he suggested that while he believes it is extremely unlikely that extraterrestrials have ever actually visited Earth , we must keep our minds open to the possible existence of civilizations a million years ahead of us in technology, where entirely new avenues of physics open up.

Part one of the series concerns personal time, and how we perceive and measure the passing of time. The second in the series deals with cheating time, exploring possibilities of extending the lifespan of organisms. The geological time covered in part three explores the ages of the Earth and the Sun. Part four covers the topics of cosmological time, the beginning of time and the events that occurred at the instant of the big bang.

On January 28, , Kaku hosted the Discovery Channel series This three-hour program discussed how medicine, the city, and energy could change over the next 50 years.

Each minute episode discusses the scientific basis behind imaginative schemes, such as time travel, parallel universes, warp drive, star ships, light sabers, force fields, teleportation, invisibility, death stars, and even superpowers and flying saucers.

Although these inventions are impossible today, the series discusses when these technologies might become feasible in the future. In , he began to appear in a series on the website Gametrailers. While his technical writings are confined to theoretical physics, his public speaking and media appearances cover a broad range of topics, from the Kardashev scale to more esoteric subjects such as wormholes and time travel.

In January , Kaku visited Oman. Policy advocacy and activism[ edit ] Kaku has publicly stated his concerns over matters including people denying the anthropogenic cause of global warming , nuclear armament , nuclear power and what he believes to be the general misuse of science.

Michio Kaku

Kaku attended Cubberley High School in Palo Alto in the early s and played first board on their chess team. Kaku graduated summa cum laude from Harvard University with a B. During the Vietnam War, Kaku completed his U. He is engaged in defining the "Theory of Everything", which seeks to unify the four fundamental forces of the universe: the strong nuclear force, the weak nuclear force, gravity and electromagnetism.

Introduction to superstrings and M-theory

Called by some "the theory of everything, " superstrings may solve a problem that has eluded physicists for the past 50 years, the final unification of the two great theories of the twentieth century, general relativity and Superstrings and M-theory are provocative and controversial, but unarguably among the most interesting and active areas of research in current physics. Called by some "the theory of everything, " superstrings may solve a problem that has eluded physicists for the past 50 years, the final unification of the two great theories of the twentieth century, general relativity and quantum field theory. Now, here is a thoroughly revised, second edition of a course-tested comprehensive introductory graduate text on superstrings which stresses the most current areas of interest, not covered in other presentations, including four-dimensional superstrings, Kac-Moody algebras, Teichmuller spaces and Calabi-Yau manifolds, M-theory membranes and D-branes, duality and BPS relations, and matrix models. Prerequisites are an acquaintance with quantum mechanics and relativity.
