The History of Quantum Theory The idea that energy could be emitted or absorbed only in discrete energy quanta was so new that it could not be fitted into the traditional framework of physics. An attempt by Planck to reconcile his new hypothesis with the older laws of radiation failed in the essential points. It took five years until the next step could be made in the new direction. This time it was the young Albert Einstein, a revolutionary genius among the physicists, who was not afraid to go further away from the old concepts. There were two problems in which he could make use of the new ideas. One was the so-called photoelectric effect, the emission of electrons from metals under the influence of light. The experiments, especially those of Lenard, had shown that the energy of the emitted electrons did not depend on the intensity of the light, but only on its colour or, more precisely, on its frequency. This could not be understood on the basis of the traditional theory of radiation. Einstein could explain the observations by interpreting Planck's hypothesis as saying that light consists of quanta of energy travelling through space. The energy of one light quantum should, in agreement with Planck's assumptions, be equal to the frequency of the light multiplied by Planck's constant.

Quantum Theory Group Carnegie Mellon University Department of Physics The quantum theory group at Carnegie-Mellon combines research on quantum foundations with research on quantum information and quantum computation. The consistent histories approach to quantum theory was initiated at Carnegie-Mellon in 1984 by Griffiths, and was subsequently developed and refined by him and by Gell-Mann, Hartle, and Omnès. It provides a fully consistent procedure for integrating probability theory into quantum mechanics, and gets rid of numerous conceptual difficulties without using hidden variables or other modifications of the standard Hilbert-space formulation of quantum theory. It has been applied to problems in cosmology, quantum optics, and quantum information, as well as to issues in the foundations of quantum mechanics.

It accounts for the fact, that in the microscopic world, various physical phenomena exhibit discrete, so-called quantized states, rather than assuming a continuum of states as postulated by classical physics. The basic tenets of quantum theory are : 1. A particle can exhibit wave-like characteristics in certain physical situations. For each particle (mass point) there exists a generally complex wave function X(x,t) (see imaginary numbers ) of the spatial coordinate vector x and time t, which meets certain mathematical conditions. X(x,t) decribes the state of the particle. X(x,t) is related to the probability of finding the particle in a position x and at time t. A typical example is the following: we have to think of electron clouds around atoms rather than electron particles: we can only identify a certain probability that at any given time a given electron will be found in a certain region around the atomic nucleus; the electron cloud is thus a kind of probability distribution of finding an electron. Instead of using the position x of the particle, the

SEARCH: Spacewatch: Backyard Astronomy advertisement Wild Science: Entrepreneur Takes On Quantum Theory By Erik Baard Special to SPACE.com posted: 04:03 pm ET 23 May 2000 Part scientist, part doctor, part entrepreneur Randell Mills is taking on such cherished theories as the Big Bang and quantum theory. His approach relies on his claim to have unleashed energy by "shrinking" the hydrogen atom's electron orbit to form what he calls a "hydrino." How radical are his ideas? Virtually nowhere on Earth is hydrogen naturally in the 'ground state.' In every molecular composition it's at a lower orbit. All I'm saying is that it can be knocked down non-radiatively with a chemical catalyst.

Quantum Theory "The Quantum Theory Group carries out theoretical research into the electronic and optical properties of low-dimensional semiconductors, organic materials, photonic systems, mesoscopic systems and quantum information. It also examines other aspects of quantum theory which promise scientific and technological potential. " Meet the group members A very rapid pace of change in Information Technology (IT) requires both a quick assesment of new and promising directions and long term research into new materials and fundamental concepts. The Quantum Theory group responds to these needs of the Institute. Quantum Theory Group members develop theoretical and computational tools to predict electronic and optical properties of new materials and low-dimensional artificially made quantum structures with promising applications in micro- opto- and nano-electronics. These theoretical approaches help to define promising experimental projects and clarify results from on-going experiments. More information can be found on personal pages of group members. Research Areas: Many body effects in systems of reduced dimensionality - Collective excitations - Pair distributions and response of the electron gas Phase diagram and energetics Magneto-optics of two-dimensional electron gas Phonons and energy relaxation - Materials science Bandstructure and densities of states - Optical properties of III-V alloys (e.g, InGaAsN

Invention of Quantum Theory unlikely partners I n 1911, the year that Rutherford made his model public, a young promising Danish physicist, Niels Bohr [1885-1962] won a Carlsberg Brewery fellowship to study for a year in England. He applied to work with Thomson at Cambridge as the plum pudding model of the atom intrigued him he knew it couldn't be right. He was accepted and traveled to Britain full of excitement and enthusiasm. However, this was decidedly not the environment for Bohr. He was terribly shy and try as he might, he was unable to attract the attention of Thomson for discussions...the great man was too busy and demands on him were great. To make matters worse, Bohr's English was poor and his initial meeting was a disaster (see the note at the right). Bohr fretted and worried that his year would pass without his having an opportunity to accomplish anything. By winter, even after joining a soccer team (he was an excellent soccer player...his brother, Harald had been a member of Denmark's 1908 olympic soccer team and became an eminent mathematician. "...more clever than I" was how Bohr characterized him.) Each holiday time, the Cavendish Laboratory had a big December party and its most famous alumus, Rutherford came from Manchester to attend. It was a racous party, with Rutherford in the middle outgoing and full of life: a very different sort of laboratory director from Thomson and Bohr was captivated. The mood and the treatment of Rutherford was so unlike the stuffy, proper atmosphere at Cavendish that he applied to finish his fellowship in Manchester by enrolling in an experimental course given there on radioactivity. Rutherford, whose general tolerance of theoreticians was well known to be minimal, agreed. Bohr abandoned Cambridge for Manchester with newfound optimism.

Quantum theory evolved as a new branch of theoretical physics during the first few decades of the 20th century in an endeavor to understand the fundamental properties of matter. It began with the study of the interactions of matter and radiation. Certain radiation effects could neither be explained satisfactorily by classical mechanics, nor by the theory of electromagnetism. In particular, physicists were puzzled by the nature of light. Peculiar lines in the spectrum of sunlight had been discovered earlier by Joseph von Fraunhofer (1787-1826). These spectral lines were then systematically catalogued for various substances, yet nobody could explain why the spectral lines are there and why they would differ for each substance. It took about one hundred years, until a plausible explanation was supplied by quantum theory. Quantum theory is about the nature of matter. In contrast to Einstein's Relativity, which is about the largest things in the universe, quantum theory deals with the tiniest things we know, the particles that atoms are made of, which are called "subatomic" particles. In contrast to relativity, quantum theory was not the work of one individual, but the collaborative effort of some of the most brilliant physicists of the 20th century, among them Niels Bohr, Erwin Schrödinger, Wolfgang Pauli, and Max Born. Two names clearly stand out: Max Planck (1858-1947) and Werner Heisenberg (1901-1976). Planck is recognized as the originator of the quantum theory, while Heisenberg formulated one of the most eminent laws of quantum theory, the uncertainty principle, which is occasionally also referred to as the principle of indeterminacy.

True Men of Letters aquire the ability to venture into different fields even if they cannot cultivate them all - from the thorns of mathematics to the flowers of poetry and judge equally well a book of metaphysics and a play. Voltaire You are Visitor No: Virgil and The Aeneid: In an age which already had a surfeit of great poets like Horace and Ovid, even they were eclipsed by Virgil, one of the finest poets produced by Western Civilisation. His crowning acheivment was the Aeneid which recounts the exploits of the Trojan, Aeneas from the sacking of Troy to the the founding of Rome. It is a tale of love, war and duty which transcends time and can touch us now as it did its contemporaries two thousand years ago and as it will our children two thousand years hence. Karl Popper - Philosopher: In our age of science it has taken a philosopher to analyse scientific method, to recognise its limitations and to question its assumptions. If this were not enough, to expand from science to the philosophy of government and to produce the most damning critique in the English Language of authoritarian rule, either of the right or the left is a tremendous achievement. The Quantum World and Superstrings I am going to tell you what nature behaves like. If you will admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying "But how can it be like this?" you will get into a blind alley from which no one has yet escaped. nobody knows how it can be like this!
