Yet when we ask ourselves thesimplest question which involves quan-titative knowledge about gravity, suchas, for example. Would a stone and apiece of lead dropped from the samepoint reach the ground at the same timeor at different times ? most of us areuncertain as to the answer. In fact, itwas the asking and the answering ofthis very question by Galileo, about1590, which may be considered as thestarting point of modern science.

Ordinary observation teaches thatlight bodies like feathers fall slowly andheavy bodies like stones fall rapidly,and up to Galileos time it was taught in the schools that bodies fall with velocities proportional totheir weights.
