In the banner at the tippy top of the page, is the equation to the right of Einstein's head $$g(C):=\sum^m_{i=1}\sum_{k\in C}\|x_k-x_C\|^2$$? Why is it x_C instead of x_i. Is this a special equation or something that somebody made up?

I think i might be seeing now that its $$g(C):=\sum^m_{i=1}\sum_{k\in C_i}\|x_k-\overline{x}_{C_{i}}\|^2$$ which makes sense.

I suggested he use a real equation... but... what the hell. Greg if you still have the photoshop files, would you consider changing the equation to a meaningful one?
