  Xenon - Wikipedia, the free encyclopedia
Xenon is a member of the zero-valence elements that are called noble or inert gases.
Xenon and the other noble gases had for a long time been considered to be completely chemically inert and not able to form compounds.
Because xenon is heavier than air, the speed of sound in xenon is slower than that in air, and when inhaled, lowers the resonant frequencies of the vocal tract.

A colorless, very heavy, odorless noble gas, xenon occurs in the earth's atmosphere in trace amounts and was part of the first noble-gas compound synthesized.
Xenon (Greek xenon meaning "stranger") was discovered by William Ramsay and Morris Travers in 1898 in the residue left over from evaporating components of liquid air.
Xenon is non-toxic, but many of its compounds are highly toxic due to their strong oxidation properties.

 Xenon Applications   (Site not responding. Last check: 2007-10-22)
Xenon makes it possible to obtain better x-rays with reduced amounts of radiation and, when mixed with oxygen, is used to enhance contrast in CT imaging and to determine blood flow.
As liquid xenon is roughly 500 times as dense as gases normally used in particle detectors, and its atoms are therefore more tightly packed, it promises to provide exquisite sensitivity and accuracy over 10 times greater than previous devices in pinpointing the positions of particles.
Xenon is not actually consumed in the detection process, and is recycled, so, aside from the initial filling volume requirement, makeup losses for these types of devices are small.

Xenon will be a streaming media monster, but the parts of the game engine that have to do with making the game fun to play (and not just pretty to look at) are probably going to suffer.

The Cell has only one PPE to the Xenon's three, which means that developers will have to cram all their game control, AI, and physics code into at most two threads that are sharing a very narrow execution core with no instruction window.

 Xenon Strobe
During discharge, the xenon gas emits broad spectrum white light, which is at nearly the same colour temperature of daylight.
For this reason, xenon flash tubes are now the universal choice for photographic flashes, since there is very little colour change when using normal daylight film.
The xenon gas becomes conductive, and the capacitor bank is discharged until the voltage is insufficient to maintain conduction in the tube, which then extinguishes.

The XBox 360's procedural synthesis techniques were explained, and a general overview of the multicore PowerPC CPU that powers the new console was given.
The Xenon's triple-core design shares some DNA with the Playstation 3's Cell processor, so it's not surprising that it also embodies many of the same assumptions about the best way to wring performance out of the sorts of extremely large transistor counts that Moore's Curves have given the latest generation of integrated circuits.
In a nutshell, software writers who develop for Xenon must take on more of the burden of optimizing their code by making it explicitly parallel, and in return they get more execution hardware to play with.
