Royal Institution Christmas Lectures (1966) : 41x2

Ever wondered why bubbles are always round even if you blow them with a square frame? Or why footballs are made out of pentagons and hexagons? Take a tour through the mathematical and cultural world of shapes - from pyramids in Egypt to the domes of Italy, and from the shape of good dice to the smell of symmetry. We'll even take a trip into hyperspace and reveal how to see in four dimensions.
