We put this lion somewhere in the desert. L0 then converges toward our cage. According to the general Wiener-Tauber theorem every other lion L will converge toward the same cage. Heisenberg might have slept here. Moebius always does it on the same side.
Algebraists do it in groups.
Those who can count and those who can't. The reason that every major university maintains a department of mathematics is that it is cheaper to do this than to institutionalize all those people. The engineer calculated the average area required per sheep, multiplied by the number of sheep, and proceeded to build a circular fence enclosing the proper area. The physicist gathered all of the sheep together as closely as possible, and built a circular fence around them. The Mathematician just laughed at them.
