Wendy Fortescue-Hubbard, our Mathagony Aunt, introduces a technique used to estimate the value of Pi by throwing 20 sticks onto the pavement.
This strange experiment was first performed by the French naturalist George-Louis Leclerc, Comte de Buffon in 1777.
In Investigating Pi, pupils at Vyners school in Hillingdon investigate this experiment. As well as trying out a scaled-down version of Buffon's experiment, teacher Steve Imisson demonstrates the polygon method for estimating Pi, which is more obviously related to circles.
