Brian Lewis: All About Science #11a – Galileo


In this episode we look at Galileo Galilei and his creation of the pendulum. He was born in Pisa, but everyone will remeber what is now considered as a myth of how Galileo dropped balls from the top of the leaning tower of Pisa.

A biography by Galileo’s pupil Vincenzo Viviani stated that Galileo had dropped balls of the same material, but different masses, from the Leaning Tower of Pisa to demonstrate that their time of descent was independent of their mass. This was contrary to what Aristotle had taught: that heavy objects fall faster than lighter ones, in direct proportion to weight. While this story has been retold in popular accounts, there is no account by Galileo himself of such an experiment, and it is generally accepted by historians that it was at most a thought experiment which did not actually take place.

We see Lewis’ signature that appeared in many of his illustrations and comic strips. Very abstract, where contemporaries like Bellamy and Noble signed in a straight signature

This week Lewis produced 2 pages – inside and outside back cover. The colours are different in the reprint of this strip in issue #16 Interesting that the publisher reprinted this so soon in a work that spanned 2 years – perhaps another indication that this inside cover was seen as disposable
