"The main method is the implosion method, where there is one sphere of material, which is compressed to make it supercritical."
" A simpler method is the gun method, where there are two pieces, one subcritical because of the limited mass, the other subcritical because of being unfavorably shaped (or in small-yield weapons, also because of mass), but such that the pieces together are favorably shaped: the first piece fits in a hole of the second piece."
