Gallileo and the Leaning Tower of Pisa

Scientists and historians alike have worked hard to prove that Gallileo’s famous experiment with two unlike objects falling at the same speed never happened.  Dr. Ullible was suspicious at how hard they were trying to assure the public that it was only a thought experiment.  It made him think that perhaps the thought experiment was more than wishful thinking An illustration on a missing page  from On Motion shows what really happened.
