So anyways I was watching Morgan Freeman's through the wormhole on science channel the other day, and I know pretty much nothing about physics and mathematics, so I pretty much take what they say for granted assuming its either a respectable theory or well accepted, but I really enjoy shows like that, or the show called The Universe on history becuase they make me think a lot, and even though I'm no good at math, they explain things so I can understand them.

Anyways back to the point, they were talking about circles that intersect at cetain angles and this guy had this really complicated shape that he made doing that that was like 200 some circles and he was using it to describe the geometry of the elementy particles. And my question is, he had a name for the shapes of circles that intersect but i cant remeber what it was and i wanted to do alittle online research and just check that out more and try to understand it.
