2001 A Spacetime Odyssey Two theories revolutionized the 20th century view of space and time Einstein's General theory of Relativity and quantum Mechanics. Their union has spawned elementary particle theories with extra spacetime dimensions, the inflationary model of bigbang cosmology, dark matter in the universe, radiation from quantum black holes and the fuzzy spacetime geometry of superstrings and M-theory. http://www.umich.edu/~mctp/sto2001/

Objective World Of Physics Presents and reviews Relativity theory, quantum Physics, and Cosmogical concepts. http://home.comcast.net/~tjbesmer/
Extractions: Objective World of Physics WEB Page of Tom Besmer Welcome to my world of Physics. On this site are found a prologue and six articles that deal with physics review and the development of a new energy concept. Reviewed are: Einstein's works, Newton 's works, Maxwell's works, Gravitational Force Field (GFF), Electromagnetic radiation, Cosmology, Quantum Physics, and the Speed of Light and developed are: a new energy concept, Frequency shifts and the Speed of light as a function of wavelength and media (GFF). It is important to understand that modern day technology has been a process. The best way to study the process is historically. e.g . The vacuum tube came before the transistor, the transistor is the precursor to the latest in integrated circuits, and Einstein's works were initiated because he thought that there was a discrepancy between the works of Newton and Maxwell. Einstein, an intellectual giant, has been voted man of the century. One aspect of his Special Theory of Relativity led to the famous E = mc He won the Nobel Prize for explaining the photo-electric effect. The papers of this site do not deny any of Einstein's accomplishments. They do however question one of his postulates "the speed of light is a universal constant, relative to nothing". The articles here deal with the variation of the speed of light as a function of media. A new energy concept is derived, developed, and introduced. It expands the present day concept of the speed of light. It turns out that the General Theory of Relativity is unnecessary if the time and distance measurements of the Special Theory of Relativity become objective and real. This is true if it can be demonstrated that the speed of light is not a universal constant, an initial condition. Its value varies as function of media and is relative to any movement of the measuring device.

It offers several advantages over the standard EVENT program of Kunszt and Nason, briefly: full event orientation is retained; Z exchange is included; different partonic final states and colour are labelled correctly. A preliminary version (0.2) is here together with a brief set of notes describing it. There was an important bug found in version 0.0. If you used that version, you are strongly advised to rerun with version 0.1. The differences are typically of order 1% for most quantities, but could be larger depending on the kinematic cuts made. In order to quickly assess the importance of the bug, there is also a program that simply integrates the term that was wrong (it runs about three times quicker than the full program).

Extractions: SEARCH ... Vacancies Quantum Optics theory in Aarhus is part of the research center QUANTOP, funded by the Danish National Research Foundation Our work is also supported by the European Union, and we profit from support from various ESF programmes. Our research activities involve basic quantum optics theory: quantum master equations, stochastic wave functions, quantized radiation fields, quantum theory of measurements, quantum phase space distributions. It finds applications for laser cooling of ions and atoms, the preparation of special states of ultra-cold atoms (Bose-Einstein condensates and Fermi-degenerate gasses), quantum computing, and in the analysis of photo-fragmentation dynamics. In addition, we contribute to work on correlated structures in highly excited atoms and on transmission of intense light fields through non-linear optical fibers. The real voyage of discovery consists not in seeking new landscapes, but in having new eyes (Marcel Proust). M.Sc. student

If you are in hurry, you easy should further-click. Seeing in the side you cannot grasp what I would like to explain to you. With Quantum-Universe is more meant, much more than only Nano, that now is mouth in all and from which you heard surely. Actually, Nano means nothing than nanometres [nm] , that is 10 m or the thousand-millionth part of a meter. Exactly the microelectronics is advancing into this area of tiniest dimensions and celebrates admiration-worthy successes. But with Quantum-Universe I my somewhat which is more general. Not only also small and even much more tiny, with areas, in which our technology can never advance despite boldest dreams in principle; but in fact including our macro surroundings and the whole universe. From the last, one has a more or less clear idea: over our solar system, our "Milky way" and the inscrutably many other galaxies in their different development stages. At the time an Australian plans to summarize all already known galaxies in a spatial card. A huge undertaking. No, on the other hand I don't want to frighten of course. Take your time, if you can, and read the websides. But, you should not at once devour all. Let's turn towards the quanta. All speak of it. Some are confident to know what are quanta. I doubt this. What therefore are quanta, that it inspires to the concept of quantum leap? Here, it behaves similarly like the term nano. In sense of Max Planck and Albert Einstein happen all the nature events discontinuous in constant steps. The smallest step is named quantum of action, a q u a n t u m therefore. Its value is incredibly small; namely S â 6,626·10
Extractions: that physics in the form of energy-momentum and space-time coordinates lives and gets projected from that topological space which represents the arena in which physical interactions take place. In quantum theory we get an abstract mathematical image of that quantum space in the form of the complete Dirac bracket, This work in theoretical physics is concerned with developing the theory that incorporates both theory of relativity and quantum mechanics into a consistent mathematical theory. One way to achieve this is to extend the manifold of the theory of relativity into a quantum space through incorporation of the quantum dynamics into that functional space. Quantum topodynamics is the field theory that derives from the topology of the quantum space.

Time Travelling Newton, Einstein, special relativity theory, quantum mechanics, equations, Lorentz factor, radius of Schwarzschild, wormholes, tunnel effect and parallel universe. http://users.pandora.be/vannoppen/science1.htm
Extractions: I) Introduction Before 1905 there wasn't much to say about time. In the 17th century Newton defined time as something that continues, no matter what, without any link with reality and according to its own nature. Everybody believed that time had its influence on the environment, but if you believed that the environment had its influence on time, you really had to be mad! That changed in 1905 with Einstein's special relativity theory, in which he showed that time can be influenced. But this doesn't mean time can be changed in such a way that you can travel to the future or the past. That's what it's all about on this pages: Is it possible to travel through time, and if possible, under which circumstances? It will become very clear that the speed of light has got a major influence on the possibility of time travelling. An object should move faster than light speed to travel through time. Therefore we use the tunnel effect, an effect in the quantum mechanics. That means that a ray of light or a bundle of electrons that is sent through a certain barrier arrives sooner at the other side of the barrier than if there wasn't a barrier.
Everett's Relative-State Formulation Of Quantum Mechanics Describes Everett's attempt to solve the measurement problem by dropping the collapse dynamics from the standard von NeumannDirac theory of quantum mechanics. By Jeffrey A. Barrett. http://plato.stanford.edu/entries/qm-everett/
Extractions: Please Read How You Can Help Keep the Encyclopedia Free Everett's relative-state formulation of quantum mechanics is an attempt to solve the measurement problem by dropping the collapse dynamics from the standard von Neumann-Dirac theory of quantum mechanics. The main problem with Everett's theory is that it is not at all clear how it is supposed to work. In particular, while it is clear that he wanted to explain why we get determinate measurement results in the context of his theory, it is unclear how he intended to do this. There have been many attempts to reconstruct Everett's no-collapse theory in order to account for the apparent determinateness of measurement outcomes. These attempts have led to such formulations of quantum mechanics as the many-worlds, many-minds, many-histories, and relative-fact theories. Each of these captures part of what Everett claimed for his theory, but each also encounters problems. 1. Introduction

BBC NEWS | Science/Nature | New Model 'permits Time Travel' In theory, you could go back in time and meet your infant father but you couldnot kill him, a new quantum model of time travel suggests. http://news.bbc.co.uk/2/hi/science/nature/4097258.stm
Extractions: The concept of time-travel is laden with uncomfortable paradoxes If you went back in time and met your teenage parents, you could not split them up and prevent your birth - even if you wanted to, a new quantum model has stated. Researchers speculate that time travel can occur within a kind of feedback loop where backwards movement is possible, but only in a way that is "complementary" to the present. In other words, you can pop back in time and have a look around, but you cannot do anything that will alter the present you left behind. The new model, which uses the laws of quantum mechanics, gets rid of the famous paradox surrounding time travel. Paradox explained Although the laws of physics seem to permit temporal gymnastics, the concept is laden with uncomfortable contradictions. The main headache stems from the idea that if you went back in time you could, theoretically, do something to change the present; and that possibility messes up the whole theory of time travel.
