Extractions: Paradoxes Contents These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn. Now someone takes the pole and tries to run (at nearly the speed of light) through the barn with the pole horizontal. Special Relativity (SR) says that a moving object is contracted in the direction of motion: this is called the Lorentz Contraction. So, if the pole is set in motion lengthwise, then it will contract in the reference frame of a stationary observer. You are that observer, sitting on the barn roof. You see the pole coming towards you, and it has contracted to a bit less than 40m. So, as the pole passes through the barn, there is an instant when it is completely within the barn. At that instant, you close both doors. Of course, you open them again pretty quickly, but at least momentarily you had the contracted pole shut up in your barn. The runner emerges from the far door unscathed. But consider the problem from the point of view of the runner. She will regard the pole as stationary, and the barn as approaching at high speed. In this reference frame, the pole is still 80m long, and the barn is less than 20 meters long. Surely the runner is in trouble if the doors close while she is inside. The pole is sure to get caught.

Investigation of atoms at temperatures approaching absolute zero. At these low temperatures, atoms start to behave less like particles and more like waves, according to the laws of quantum mechanics.

Extractions: Welcome to ATOMCOOL! Matter Wave Solitons in a 1D Trap You have reached the research group of Dr. Randall G. Hulet in the Department of Physics and Astronomy at Rice University Professor Hulet investigates atoms at temperatures as low as a few nano-Kelvin. At these low temperatures the quantum mechanical wavelengths of the atoms can be as large as 1 micron, greatly altering normal atomic behavior. Hulet and his group have used laser cooling and atom trapping techniques to explore this exotic regime of matter, investigating ultracold atom collisions and quantum statistical effects, such as Bose-Einstein condensation. Collisions between ultracold atoms can reveal the subtle nature of their mutual interaction. Hulet and group use laser spectroscopy to probe the interatomic interaction potential. By this technique they discovered that two Li atoms weakly attract each other at very low temperature. Theorists believed that this fact would prevent lithium from undergoing a Bose-Einstein condensation, the paradigm of all quantum statistical phase transitions. In 1995, however, Hulet and his group succeeded in coaxing a gas of magnetically confined Li atoms to Bose condense. Subsequent investigation of this novel system has lead to the direct observation of condensate growth and collapse. This work is sure to alter the way in which we think about weakly interacting Bose gases.

http://www.arstechnica.com/wankerdesk/01q1/nanotech-1.html

Extractions: Microelectromechanical systems (MEMS) are movable devices manufactured on semiconductors using the same techniques used to make computer chips. They are very small (the smallest separations between their parts are on the order of micrometers). So far, classical mechanics has done a good job of guiding the design of these devices. However, in an article (subscription required for access) in the March 9, 2001 edition of Science, H. B. Chan, V. A. Aksyuk, R. N. Kleiman, D. J. Bishop, and Federico Capasso experimentally demonstrated that quantum effects become significant at such size scales. Some background information may be useful, before describing the experiment. Quantum electrodynamics (the part of quantum theory dealing with electromagnetic phenomena) predicts that empty space isn't really empty, so that there is no such thing as a perfect vacuum. Even in a vacuum, and even at a temperature of absolute zero, all kinds of particles pop in and out of existence as a consequence of the famous Uncertainty Principle of quantum mechanics. These particles pop into existence (in particle-antiparticle pairs), hang around for a little while, but must then must disappear again. How long they can hang around depends on how heavy the particles are the heavier the particles, the faster they must disappear, but even light particles can hang around for very short periods of time. These particles are called virtual particles, because they normally can't be directly detected - you might say they
Accretion Disk Polar Jetting, Binary Star Formation And Nemesis

http://www.aplg.com/nemesis.htm

Extractions: The Hubble Telescope has provided perplexing images of star formation . Gone is the old theory of a simple collapse of a space cloud into a solid ball. Gone also is the theory of a simple accretion disk gradually winding its way to forming star. We now see volumous jets of material mysteriously being "ejected" along the axis of the accretion disk at high velocity and extending light years out from the disk center. In addition massive quantities of material are seen as blobs at some distance from the visible outer ends of the jets. What can explain these newly observed phenomena? The star is not ejecting material but simply holding material in orbit. Outflows could be buildups of otherwise incoming particles retarded by impulses from the outer reaches of the "jetting" orbital particles. Illumination is provided by heating due to collisions between particles. Observed beading within a jet may be due clumping within the original dust cloud. The accretion disk is not a barrier to material reaching the star's core. The disk is there as a storehouse for the angular momentum imbalance of the incoming dust cloud. It varies in size, shape, and orbital plane throughout star formation as dictated by dust particles within its influence. What happens as a star system's development matures? We know from our own solar system that an accretion disk can condense into planets which orbit the star in the plane of the original accretion disk. But what happens to any polar ejectate material in a highly eccentric elliptical polar orbit? It is possible that it may also condense into a sizeable body. Depending on its size it would be another star ranging from very bright to dark or it could even be a large planet.

http://scienceworld.wolfram.com/physics/QuantumMechanics.html

Extractions: 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

Extractions: Shan, Gao (2002) Quantum mechanics and discontinuous motion of particles. Full text available as: Adobe PDF (.pdf) We discuss a new realistic interpretation of quantum mechanics based on discontinuous motion of particles. The historical and logical basis of discontinuous motion of particles is given. It proves that if there exists only one kind of physical reality-particles, then the realistic motion of particles described by quantum mechanics should be discontinuous motion. We further denote that protective measurement may provide a direct method to confirm the existence of discontinuous motion of particles.

Extractions: doi:10.1142/S0217979297000162 STATISTICAL MECHANICS OF CLASSICAL PARTICLES WITH GRAVITATIONAL INTERACTIONS: EXACTLY SOLVABLE (FOR N ) IN d = 1 AND d MICHAEL K.-H. KIESSLING Department of Mathematics, Rutgers University, New Brunswick, N.J. 08903 This paper is concerned with a curious gap in a string of exactly solvable models, a gap that is suggestively related to a completely integrable nonlinear PDE in d = 2 known as Liouville's equation. This PDE emerges in a limit N from the equilibrium statistical mechanics of classical point particles with gravitational interactions (SMGI) in dimension d = 2 which, accordingly, is an exactly solvable continuum model in this limit. Interestingly, in d = 1 and all d 2, the SMGI can be, and partly has been, exactly evaluated for all N . This entitles one to suspect that the SMGI for d = 2 is likewise exactly solvable for N , but currently this is an unproven hypothesis. If this conjecture can be answered in the affirmative, spin-offs in various areas associated with Liouville's equation, such as vortex gases, superfluidity, random matrices, and string theory can be expected.
