Humble Pi: A Comedy of Maths Errors by Matt Parker. Proof that it may be my kind of math book came in the final paragraph of an explanation of resonance using a child on a swing as an example:
Quote:

Only if you push exactly at the rate which matches when the child is directly in front of you and starting their descent will you achieve success. When the timing of your effort matches the frequency the swing is moving at, each push adds a little more energy into the system. This will build up with each push until the child is moving too fast to easily inhale and their screaming will finally cease.
