Sign some equations

I found this in my Google Reader Feeds tonight. Apparently it came from here.

After having a mental confusion moment today and confusing the equations for the area of a circle and the volume of a sphere (at least when the numbers came out I realised they couldn’t be right), this seemed to appear at a perfect time.

This was perfect timing. I love geeky math silliness and it made my day that much better.
