I have to qualify my responses here. I'm no mathematician. I don't understand much, although it was my favourite thing at primary school when I was little. But whether I understand or not, someone talking maths (or physics) at me is hott hott hott (if they can cope that I probably have no idea what they're talking about). One day I might meet the special person who can unlock the barriers in my head and let the essential maths juice flood in, and everything will fall into place, and there'll be world peace and flowers and ice cream for everyone.
