Bablyonian use of square root of two
Photographs and analysis of an 1800 BC Babylonian table showing the diagonal of a square and ancient knowledge of the value of square root of two – expressed in base 60. A great extension resource. No previous knowledge of Babylonian required, but will make more sense if students know about different number base system. Full mathematical analysis on the site.
Bearings
