Strategic search

If we divide a circle into 360 equal angles, we end up with one degree incremental vectors in which we can look around ourselves on a planar surface. When we misplace something, we can head off in 360 different directions. If we then allow for up and down angles of equivalent size, then for the sphere surrounding us at every moment, there are 41,253 directions we can look. Given all these options, we must choose wisely.

Technically, the number of directions is computed from A=4πr² where r=360/2π. [Square degree]
