Mathematics

If you ever came across a vector in a high-school science class, it probably looked quite simple: a little arrow you might draw on a diagram to show the motion of a train or the forces on a swinging pendulum. An arrow pointing right would cancel an arrow pointing left, or → + ← = 0. Add together two arrows pointing in the same direction, you get one twice as long: →. A rightward arrow plus an upward one? You’ve got yourself a diagonal: → + ↑ =  ↗.

Were you one of those reluctant mathematics students who complained, ‘What’s the point of all this?’ If so, rest assured: Michael Brooks has made a compelling case for the role mathematics has played in making ‘civilisation’ possible. If you still need convincing, he also discusses research suggesting that doing maths is good for your brain.
