h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

A very good entry, even though I'm a little bewildered by the idea of calculus merely being a game - there was me thinking I'd been doing work in A Level Maths, instead of the game of "Calculus, Calculus, and more Calculus".

One slight error is the "rule" which says "If you differentiate log x, you get 1/x." That's only true if you're using the natural logarithm - which should be written either log (subscript)e, or ln - the way it appears on most calculators. "log x" on its own would imply log base 10, which doesn't differentiate too neatly.

Sorry to pick holes; it's an otherwise great entry!

"That's only true if you're using the natural logarithm"

Ah yes, you're right. Thanks for pointing that out.

I think calculus is quite fun, so in order not to scare people away from what might otherwise seem like a frighteningly complicated mathematical technique, I thought it would be a good idea to think of it like a game. It makes it feel much friendlier.
