Sonoluminescence

Sonoluminescence
Single-bubble sonoluminescence - A single, cavitating bubble. Video of synthetic wound cavity collapsing creating sonoluminescence. Long exposure image of multi-bubble sonoluminescence created by a high-intensity ultrasonic horn immersed in a beaker of liquid History[edit] The sonoluminescence effect was first discovered at the University of Cologne in 1934 as a result of work on sonar. In 1989 an experimental advance was introduced by Felipe Gaitan and Lawrence Crum, who produced stable single-bubble sonoluminescence (SBSL). Properties[edit] Sonoluminescence can occur when a sound wave of sufficient intensity induces a gaseous cavity within a liquid to collapse quickly. Some facts about sonoluminescence: Rayleigh–Plesset equation[edit] The dynamics of the motion of the bubble is characterized to a first approximation by the Rayleigh-Plesset equation (named after Lord Rayleigh and Milton Plesset): Mechanism of phenomenon[edit] In 2002, M.

Reseñas HOLY OTHER Held TriAngleRecords Es una dicha descubrir que algunos proyectos poseen cierta propensión hacia el olvido. Música que parte de cierto desinterés por la permanencia: líneas de bajo densas y apretadas, beats que entran y salen como ligeros pececillos, y modulaciones que bien podrían observarse en un microscopio.

Small in size, big on power: New microbatteries the most powerful yet Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery -- and then recharge the phone in the blink of an eye. Developed by researchers at the University of Illinois at Urbana-Champaign, the new microbatteries out-power even the best supercapacitors and could drive new applications in radio communications and compact electronics. Led by William P. "This is a whole new way to think about batteries," King said. With currently available power sources, users have had to choose between power and energy. "There's a sacrifice," said James Pikul, a graduate student and first author of the paper. The new microbatteries offer both power and energy, and by tweaking the structure a bit, the researchers can tune them over a wide range on the power-versus-energy scale.

Physics 20b: Introduction to Cosmology - Spring 2010 - Download free content from UC Irvine on iTunes - StumbleUpon May 2007 Oh Happy Days! I finally got a hold of this Electric Love Muffin Cd that I have been trying to get for years. This is one album that was responsible for really turning my head around for some amazingly well-written kick ass college rock! (haha--yes, i am fully aware of how hopelessly geeky that sounds). The year was 1988 and i wasn't much older than 13 at the time. anyway...Let's just say that the radio station and the DJ's selections were frying my mind on a minute-by-minute basis every night. Once a week, they would have a segment of their show where they would select a newly released record and play a full side of the record straight through to help promote it. I also taped a lot of other stuff on that tape, but the Electric Love Muffin stuff really began to grow on me and get burnt into my mind. Great songs, insanely competent playing, wonderful record.

Gravitational wave In physics, gravitational waves are ripples in the curvature of spacetime that propagate as a wave, travelling outward from the source. Predicted in 1916 by Albert Einstein to exist[1] on the basis of his theory of general relativity,[2] gravitational waves theoretically transport energy as gravitational radiation. Sources of detectable gravitational waves could possibly include binary star systems composed of white dwarfs, neutron stars, or black holes. The existence of gravitational waves is a possible consequence of the Lorentz invariance of general relativity since it brings the concept of a limiting speed of propagation of the physical interactions with it. Introduction[edit] In Einstein's theory of general relativity, gravity is treated as a phenomenon resulting from the curvature of spacetime. Linearly polarised gravitational wave In principle, gravitational waves could exist at any frequency. Effects of a passing gravitational wave[edit] . Sources of gravitational waves[edit] and .

Teleportation Teleportation is the name given by science fiction writers to the feat of making an object or person disintegrate in one place while a perfect replica appears somewhere else. How this is accomplished is usually not explained in detail, but the general idea seems to be that the original object is scanned in such a way as to extract all the information from it, then this information is transmitted to the receiving location and used to construct the replica, not necessarily from the actual material of the original, but perhaps from atoms of the same kinds, arranged in exactly the same pattern as the original. A teleportation machine would be like a fax machine, except that it would work on 3-dimensional objects as well as documents, it would produce an exact copy rather than an approximate facsimile, and it would destroy the original in the process of scanning it. In 1993 an international group of six scientists, including IBM Fellow Charles H. C.H. Experimental Articles D.

Damo Suzuki Biography[edit] As a teenager, Suzuki spent the late 1960s wandering around Europe, often busking.[1] Suzuki converted to the Jehovah's Witness.[citation needed] He returned to music in 1983, and currently leads what is known as Damo Suzuki's Network - as he tours, he performs live improvisational music with various local musicians, so-called "Sound Carriers".[4] Discography[edit] Damo Suzuki performs on the following albums: References[edit] External links[edit] STEPHEN HAWKING: How to build a time machine By STEPHEN HAWKING Created 7:47 PM on 27th April 2010 All you need is a wormhole, the Large Hadron Collider or a rocket that goes really, really fast 'Through the wormhole, the scientist can see himself as he was one minute ago. But what if our scientist uses the wormhole to shoot his earlier self? He's now dead. Hello. Time travel was once considered scientific heresy. To see how this might be possible, we need to look at time as physicists do - at the fourth dimension. But there is another kind of length, a length in time. To see what that means, let's imagine we're doing a bit of normal, everyday car travel. Let's indulge in a little science fiction for a moment. Physicists have been thinking about tunnels in time too, but we come at it from a different angle. Enlarge Nothing is flat or solid. Unfortunately, these real-life time tunnels are just a billion-trillion-trillionths of a centimetre across. The fastest manned vehicle in history was Apollo 10. Paradoxes are fun to think about.
