While reading about surface tension,i got to know that water drops are spherical because for a given volume the sphere have minimum area.I thought about proving this fact (for a given volume,,sphere have minimum surface area) but now i understand the complexity of situation as I don't know how to even approach to prove it..
I just want this problem to be solved.I shall be highly obliged if someone of you give me a hind for approach to solve this question. thanks
This is not a trivial result. You can read: http://www.math.utah.edu/~treiberg/isoperim/isop.pdf
