Voxel
A voxel represents a value on a regular grid in three-dimensional space.
Basically, the 3D equivalent of the 2D pixel.

Definition: Accretion Disk
Accretion Disk
The disk of stuff you see circling black holes in artist renderings like the one in the picture.
More formally..
An accretion disk is a structure (often a circumstellar disk) formed by diffuse material in orbital motion around a massive central body. The central body is typically a star. Friction causes orbiting material in the disk to spiral inward towards the central body.
Hear about accretion disks and a LOT more interesting and mind blowing stuff about astrophysics in the TEDRadio Hour podcast below!

Why Canada’s Banning of Dire Straits’ Money for Nothing is Bad Policy
The Canadian Broadcast Standards Council (CBSC) issued a ruling today which censored Dire Straits’ mega-hit song from over 25 years ago, Money for Nothing. The CBSC said the song should either be banned, or suitably edited, for its use of the homophobic word “faggot”, three times. (CBC, Jan 13 2011; CSBC Decision)
(I’d have embedded the actual music video but those *^&*@$ at YouTube have all these copyrights rules now that don’t let them be seen in Canada and other countries).
I understand the principle to censor the song, but completely disagree with the psychology of the action. For the sake of an ideal, the fight against homophobia just took a step backward rather than a step forward.
