The British General Election (May 1997) is an example of how simple mathematical ideas help in understanding information that involves numbers.
Daniel Bernoulli (1700-1782) discovered the relationship between the density of a fluid in a pipe, the speed it is travelling in the pipe and the pressure exerted by the fluid against the walls of the pipe. This is the story of what happened.

This problem is easy to describe but it is one of mathematics' unsolved problems.

Have you ever been in an aeroplane on a smooth flight when suddenly the plane bumps up and down for a short time as it goes through turbulent air? The study of turbulence is used to understand a range of phenomena from the simple squirting of a jet of water to the activity of the sun.
Mark Langley, a student at Hills Road Sixth Form College in Cambridge, tells us about his experiences doing A-level Mathematics.
