Does this seem right to you? Double Integral over the unit sphere of (x,y,z)/(x^2+y^2+z^2)^3/2 dot (x,y,z)darea = darea/sqrt(x^2+y^2+z^2) = surface area of sphere = 4pi? It seems too easy, just want to make sure.

Double Integral over the unit sphere of
(x,y,z)/(x^2+y^2+z^2)^3/2 dot (x,y,z)darea

= darea/sqrt(x^2+y^2+z^2) = surface area of sphere = 4pi?

It seems too easy, just want to make sure.

>>	Anonymous Wed May 2 02:13:20 2012 No.4638183 The surface area of the unit sphere is 4pi, yes. >>4638145 Maybe it's related to information theory.

>>	Anonymous Wed May 2 02:21:15 2012 No.4638215 >>4638183 game theory is about strategic decision making by rational actors though. Like I said i've no physics training but I really fail to see where it applies. Unless.........particles are rational actors and try to maximize potential gain.....
