Galileo tried to measure the diameter of the star Vega (Alpha Lyrae)
using a piece of rope, and realising that he needed to take into account
the finite size of the pupil of the eye, he measured that too. Not only
is it fun to try to repeat these experiments for yourself, they also act
as a great introduction to practical historical astronomy.
