Schedule Duality, Spacetime and Quantum Mechanics Edward Witten, Institute for Advanced Study (Princeton) In the last few years, physicists have learned that the different string theories discovered and studied in different ways are limiting cases of a single, more powerful theory, known as M theory. "M" stands for magic, mystery, or matrix, according to taste. Some of these developments will be explained in this lecture. Edward Witten, professor of physics at the Institute for Advanced Study in Princeton, N.J., is arguably the premier theoretical physicist of our time. Renowned for his many contributions to particle physics and string theory, Witten has almost single-handedly constructed a new branch of mathematical physics For his achievements, he has been awarded mathematics' highest prize, the 1990 Fields Medal. A member of the National Academy of Sciences, he is a recipient of a MacArthur Prize, the Dirac Medal, and many other honors.

See here for details of an adventurous PhD project. Dr. Mark J. Hadley A Gravitational Explanation for Quantum Mechanics My work offers an explanation for quantum phenomena in terms of classical general relativity. Far from being incompatible the two great theories of the 20th century are shown to be closely related. Quantum theory gives clues to the small scale structure of space and time through the EPR experiments and the Kochen Specker paradox. In return general relativity can account for the strange effects seen in quantum theory. The crucial link is a relaxation of the strict causal structure that is normally imposed upon Einstein's theory, but which forms no part of the mathematical structure. This controversial work contrasts with the mainstream view that the theories are incompatible - with the favoured remedy being to discard general relativity and replace it with a quantum theory of gravity.

Because it holds that energy and matter exist in tiny, discrete amounts, quantum mechanics is particularly applicable to ELEMENTARY PARTICLES and the interactions between them. According to the older theories of classical physics, energy is treated solely as a continuous phenomenon (i.e., WAVES by Max PLANCK , who proposed that the energies of any harmonic oscillator , such as the atoms of a blackbody radiator, are restricted to certain values, each of which is an integral (whole number) multiple of a basic minimum value. In 1905 Albert EINSTEIN proposed that the radiation itself is also quantized, and he used the new theory to explain the PHOTOELECTRIC EFFECT. Niels BOHR used the quantum theory in 1913 to explain both atomic structure and atomic spectra, showing the connection between the energy levels of an atom's electrons and the frequencies of light matrix uncertainty principle , enunciated by Heisenberg in 1927, which places an absolute theoretical limit on the accuracy of certain measurements; as a result, the assumption by earlier scientists that the physical state of a system could be measured exactly and used to predict future states had to be abandoned. Other developments of the theory include quantum statistics, presented in one form by Einstein and S.N. Bose (Bose-Einstein statistics, which apply to BOSONS) and in another by Dirac and Enrico FERMI (Fermi-Dirac statistics, which apply to FERMIONS); quantum electronics, which deals with interactions involving quantum energy levels and

52. Bohmian Mechanics And The Foundations Of Quantum Mechanics John Bell and Bohmian QMCategory Science Physics quantum mechanics Interpretations...... Foundations of quantum mechanics. Nobody has explained why we should worryabout the foundations of quantum mechanics better than John Bell http://www.math.rutgers.edu/~oldstein/quote.html

Mathematical Physics No attempt will be made here to explain what mathematical physics is about. There is no general agreement even among the experts. Moreover, this field of research is regarded as somewhat dubious by many physicists. However, the following words of Maxwell are right on target: The first processes, therefore, in the effectual studies of the sciences, must be ones of simplification and reduction of the results of previous investigations to a form in which the mind can grasp them. J.C. MAXWELL On Faraday's lines of force Foundations of Quantum Mechanics Nobody has explained why we should worry about the foundations of quantum mechanics better than John Bell: ... conventional formulations of quantum theory, and of quantum field theory in particular, are unprofessionally vague and ambiguous. Professional theoretical physicists ought to be able to do better. Bohm has shown us a way. J.S. BELL Speakable and Unspeakable in Quantum Mechanics It would seem that the theory [quantum mechanics] is exclusively concerned about "results of measurement", and has nothing to say about anything else. What exactly qualifies some physical systems to play the role of "measurer"? Was the wavefunction of the world waiting to jump for thousands of millions of years until a single-celled living creature appeared? Or did it have to wait a little longer, for some better qualified system ... with a Ph.D.? If the theory is to apply to anything but highly idealized laboratory operations, are we not obliged to admit that more or less "measurement-like" processes are going on more or less all the time, more or less everywhere. Do we not have jumping then all the time?

55. Rudiments Of Quantum Theory Though admittedly more complex, it is possible to follow a thread throughthe last four centuries up to the birth of modern quantum mechanics. http://www.chembio.uoguelph.ca/educmat/chm386/rudiment/rudiment.htm

Rudiments of Quantum Theory Quantum theory was not created "out of the blue". It's mathematical framework and ideas grow out of a long history of classical mechanics. A number of certain experiments around the turn of the century created the need to replace the classical theory of matter with a new quantum theory. The first attempt's (Bohr) had remarkable yet limited success. This became known as the Old Quantum Theory. Classical Tour Experimental Tour Quantum Tour Mathematical Basics ... Simple Quantum Models An important aspect of understanding of one's position is to appreciate where one came from. This is also true of modern science. Though admittedly more complex, it is possible to follow a thread through the last four centuries up to the birth of modern quantum mechanics. Rene Descartes is often credited as the Father of Modern Mathematics. While a mercenary soldier, he experienced a dream one night that triggered in his mind the idea of modern algebra. (Some nightmare!) It is helpful to follow a short tour from Descartes through to Newton, Bernoulli, Euler, Hamilton, Maxwell, Einstein, Schrodinger, Heisenberg, and Dirac. It is revealing to see how the mathematical ideas of one generation opened new avenues for the next.

Modern Physics Quantum Physics Quantum Mechanics General Quantum Mechanics Quantum Mechanics Quantum mechanics is the description of motion and interaction of particles at the small scales where the discrete nature of the physical world becomes important. Quantum mechanics represented a fundamental break with classical physics , in which energies and angular momenta were regarded as continuous quantities that could change by arbitrary amounts. The first break with classical physics was performed by Planck who, in order to explain the observed spectrum of a blackbody, was forced to postulate that the oscillators in a blackbody could attain only certain quantized energies. Niels Bohr had a large influence on the development of quantum mechanics through his so-called " Copenhagen Interpretation ," a philosophical construct which was formulated to provide a fundamental framework for understanding the implicit assumptions, limitations, and applicability of the theory of quantum mechanics. Einstein subsequently postulated that electromagnetic radiation could exist only in discrete units, called

59. Many-Worlds Interpretation Of Quantum Mechanics Interpretation of quantum mechanics due to Hugh Everett according to which many universes exist in parallel at the same space and time; by Lev Vaidman. http://plato.stanford.edu/entries/qm-manyworlds/

version history HOW TO CITE THIS ENTRY Stanford Encyclopedia of Philosophy A B C D ... Z content revised MAR Many-Worlds Interpretation of Quantum Mechanics The Many-Worlds Interpretation (MWI) is an approach to quantum mechanics according to which, in addition to the world we are aware of directly, there are many other similar worlds which exist in parallel at the same space and time. The existence of the other worlds makes it possible to remove randomness and action at a distance from quantum theory and thus from all physics. 1. Introduction 2. Definitions 2.1 What is "A World"? 2.2 Who am "I"? ... Related Entries 1. Introduction The fundamental idea of the MWI, going back to Everett 1957 , is that there are myriads of worlds in the Universe in addition to the world we are aware of. In particular, every time a quantum experiment with different outcomes with non-zero probability is performed, all outcomes are obtained, each in a different world, even if we are aware only of the world with the outcome we have seen. In fact, quantum experiments take place everywhere and very often, not just in physics laboratories: even the irregular blinking of an old fluorescent bulb is a quantum experiment. There are numerous variations and reinterpretations of the original Everett proposal, most of which are briefly discussed in the entry on
