Aww, shucks Petrol - you're too kind.

We've all got our strengths and weaknesses, I just happen to have something of an afinity for maths - provided you don't go getting all parametric on me. Calculus seriously kicks my backside. Too many X's and 'Xs - gimme an example with words, and not a problem - gimme an example with Xs Ys and other abbreviated symbols and I'm off in the land of nod.

Make's me think of a sig I read somewhere. To paraphrase,

I got into science to become famous. Haha - that's like becoming a priest to meet girls....
