The characteristic time for a generation is roughly the time required to funny pictures cross the diameter funny pictures of the sphere of fissionable material. A critical mass of uranium is about the size of a baseball (0.1 meters). The time, T, the neutron would take to cross the sphere is: T = 0.1 meters 1 x 10 7 meters/second = 1 x 10 -8 seconds The complete process of a bomb explosion is about 80 times this number, or about a microsecond. This time was informally known as a 'shake' ("as fast as the shake funny pictures of a lamb's tail") by the physicists at Los Alamos.
