How to enrich Uranium - Periodic Table of Videos
Uranium enrichment has been in the headlines lately - but what does it mean exactly?
Enriched uranium is a critical component for both civil nuclear power generation and military nuclear weapons. The International Atomic Energy Agency attempts to monitor and control enriched uranium supplies and processes in its efforts to ensure nuclear power generation safety and curb nuclear weapons proliferation.
During the Manhattan Project enriched uranium was given the codename oralloy, a shortened version of Oak Ridge alloy, after the location of the plants where the uranium was enriched. The term oralloy is still occasionally used to refer to enriched uranium. There are about 2,000 tonnes (t, Mg) of highly enriched uranium in the world,[1] produced mostly for nuclear weapons, naval propulsion, and smaller quantities for research reactors

Windows 7 vs. Vista
i have tested Windows 7 retail version and all i can say is.. Fan Bleeding Tastic!!
Finally Microsoft got their act together. i thought Microsoft was going to mess up Windows 7 like they did with Vista at the beginning' but they didn't. Everything seems to work much better than all the beta version of Windows 7 I tested, and i think its probably even better than vista.
I did hours of multitasking, opened multiple editing software and edited for many hours and left them open for over 24 hours and not a single crash, freeze, or glitches occurred.
i have tested out Windows 7 for a couple days now' and it's a stable OS but it will have some minor problems like incompatible issues and a few glitches but as a whole!! The OS its very reliable and stable.

Station Fire plume timelapse, August 29, 2009
The La Canada Station Fire's smoke plume is visible all over southern California. Here you can watch it literally explode into a pyrocumulous cloud in the second shot. These two timelapse shots were captured via digital camera and are presented around 75x actual speed (a little over a minute of actual time per second of viewing). The mushroom cloud effect is amazing evidence of the fire's power. Also amazing is how fast the plume moves, even when viewed from many, many miles away
