I believe I do have a timeline of events that you might find illuminating.
Newt is teaching his class about Plato and Aristotle.
He explains that Aristotle was wrong to claim that heavy things fall faster than lighter things. He uses a short poem to remind them of this:
Whether they’re large or whether they’re small
Has no effect on the rate which things fall
But whether you choose to accept this or not’ll
Depend on your faith in that fool, Aristotle
He asks one of his students, Spencer, who it was that proved Aristotle wrong in 1592. Spencer, who had not been listening, incorrectly guesses Plato. The answer was Galileo.
