Agner Krarup Erlang (1878 - 1929)The mathematics underlying today's complex telephone networks is still based on his work. Erlang was the first person to study the problem of telephone networks.
Call routing in telephone networksFind out how modern telephone networks use mathematics to make it possible for a person to dial a friend in another country just as easily as if they were in the same street, or to read web pages that are on a computer in another continent.

Understanding turbulenceHave 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.
Student interview - Mark LangleyMark Langley, a student at Hills Road Sixth Form College in Cambridge, tells us about his experiences doing A-level Mathematics.
Daniel Bernoulli and the making of the fluid equationDaniel 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.
