BANG!  The Anatomy of Explosions MUNITIONS - the Atomic Bomb Cont. Fission bombs use an element like uranium-235 to create a nuclear explosion, the fuel must be kept in separate subcritical masses, which will not support fission, to prevent premature detonation. The two or more subcritical masses must be brought together to form a supercritical mass at the time of detonation. To bring the subcritical masses together into a supercritical mass, two techniques are used; Gun-triggered and Implosion. The bomb known as Little Boy (left) was the first nuclear weapon used in warfare dropped on Hiroshima by the B-29 Enola Gay. The Fat Man bomb was the second nuclear weapon used in warfare and was dropped on Nagasaki in 1945. Fission bombs worked, but they weren't very efficient.

CGArena releases 300 free animal reference images Wednesday, April 18th, 2012 | Posted by Jim Thacker Fleas to meet you: one of over 300 varied reference images of animals and birds available on CGArena. CGArena has added over 300 photographic reference images of birds and animals to its online library. The material, which is free to use, spans the usual range of dogs, cats and livestock, plus a fair range of birds and more exotic creatures. Resolutions vary from image to image, but most of the files we tried were at least 4,000 x 3,000 pixels or greater, which should be plenty large enough for most purposes.
