On the mathematics line, some physicist... (I forget the name Kinku? First name was Michael I believe), had an interview/show on TechTV about his perceptions of finding a Grand Unified Theory.

He said routinely rejected theories and equations because they were too complex, every time saying God's universe would be governed by beautiful (&simple*) equations. Though I think String Theory is off in unprovable never-never-land, there was a lot that I learned from that statement.

* = By simple, I mean short an elegant, without a lot of fudge constants and operators, I'm not saving the Creator would be afraid of a flux integral or something like it :)
