Hello everyone...... I mistakenly posted this question in a math section, met with insufficient answers. My fault there, but here's the gist: How do you find the surface area of an n-dimensional sphere? I ran across this concept in a stat-mech class a long, long time ago.......didn't understand it very well at the time. It was an aside kind of thing the prof did during a lecture. I thought if I spent a little one-on-one time with the concept I would 'get it', but the rigors of homework, research, etc disallowed the quality time intended, so I ended up putting this into my mental closet for rainy-day thinking, and of course, never got back to it, but I'm still very curious about it. Can someone do this derivation and explain the thinking behind it please????
