Some math students have read
about how a blind dart shooter can be used to approximate π.
The basic process is based
on the fact that, when randomly thrown, darts hit portions of the target board
at a rate corresponding to the area of that portion in relation to the whole
board. here we have a circle (area πr2) and a square (with area 4r2).
So the ratio of darts hitting the circle to the the darts thrown should be the
ration of these areas, which is π/4.
Take note: to get a really
good approximation, you have to throw a lot of darts, and awful lot of darts!
Disclaimer: a skilled dart
shooter would mess up the pi!!
