The third installment in our series on the shape of astronomical systems, this article explores galaxies and the universe beyond our solar system.
This is about a fiendishly difficult jigsaw and how to solve it
using a computer program.
Explain why, when moving heavy objects on rollers, the object moves
twice as fast as the rollers. Try a similar experiment yourself.
How do you write a computer program that creates the illusion of stretching elastic bands between pegs of a Geoboard? The answer contains some surprising mathematics.
