017 Rhind Mathematical Papyrus1 9 Feb 2010

Tue, 9 Feb 10

An ancient Egyptian papyrus from around 1550 BC, used to train scribes. It contains 84 different calculations to help with various aspects of Egyptian life, from pyramid building to working out how much grain it takes to fatten2 a goose. Neil MacGregor, Director of the British Museum, looks at man's early experiments with numbers and discovers how the Egyptians’ understanding of mathematics enabled them to build a state machine, which could manage food supplies and even compute3 the flood levels of the Nile.
