What's Special About This Number? 0 is the additive identity. 1 is the multiplicative identity. 2 is the only even prime. 3 is the number of spatial dimensions we live in. 4 is the smallest number of colors sufficient to color all planar maps. 5 is the number of Platonic solids. 6 is the smallest perfect number. 7 is the smallest number of faces of a regular polygon that is not constructible by straightedge and compass. 8 is the largest cube in the Fibonacci sequence. 9 is the maximum number of cubes that are needed to sum to any positive integer. 10 is the base of our number system.
a math prof made this cool site talking about special quality about thousands of numbers...good mental masterbation for all the number theory junkies out there (you know who you are)...

YouTube - Video explains the world's most important 6-sec drum loop
5:47 pm EST, Feb 15, 2007
This fascinating, brilliant 20-minute video narrates the history of the "Amen Break," a six-second drum sample from the b-side of a chart-topping single from 1969. This sample was used extensively in early hiphop and sample-based music, and became the basis for drum-and-bass and jungle music -- a six-second clip that spawned several entire subcultures. Nate Harrison's 2004 video is a meditation on the ownership of culture, the nature of art and creativity, and the history of a remarkable music clip.
UPDATE - A detour into the strange world of quantum computing

A detour into the strange world of quantum computing 2/12/2007 12:16:26 PM, by John Timmer On Tuesday, a startup company called D-Wave is going to publicly demonstrate a quantum computing system that they call Orion. Is this the dawn of a new era of computing or simply an exercise in hype? It's hard to say prior to the announcement, but my guess is a little of both. To fully appreciate why, we'll have to take a detour into the strange world of quantum computing.
they claim to have a working 16 bit quantum computer...even if its extremely limited in its applications I'm very excited to see this technology moving forward so quickly...
UPDATE: so I just heard from someone that was at the demo, it apears to have worked as advertised...pretty amazing...
