00:00Part of what I wanted to show in the book is that scientists also cook with water. Scientists,
00:06Ultimately, they are also human beings who exist within a context. Even though we're talking about this, about the tower.
00:11of ivory, of the great eminences, all the astronomical and scientific discoveries in the entire history of humanity are
00:18have done for humans so far.
00:20And humans eat, we have houses, we have families, and I wanted to try to represent that. So, it occurred to me, because there are
00:28Several episodes there, and it's very early in the book, Galileo Galilei's shopping list.
00:34In Florence, I was in Florence and it's an episode I narrate there; I was invited to give a lecture in
00:39The Archetri Observatory, which is practically next door, was opposite, where Galileo died when I was under house arrest.
00:47And among the documents that have been preserved from Galileo are his shopping lists. And that was when Galileo was
00:53in Venice, and then he would say, shoes for Vincenzo, for the son, oranges, something a gentleman owed him, came badly
01:01empty, which was the one he liked, hemp, pitch, tin tubes.
01:07There are the components of the telescope, and some that ultimately turned out not to be useful, because he did many experiments before, but
01:14Galileo had to do the shopping, he had to buy shoes for his son, he owed money to people.
01:19And ultimately, Galileo was practically living on borrowed time when he started out, so it's clear that Galileo wasn't doing
01:25He earned enough money as a math teacher in Venice, so he was also a bit of a go-getter, an entrepreneur, although we thought that
01:33Scientists are those who live over there in the universities; scientists also have to take initiative to solve those problems.
01:38problems that no one has thought of, that don't even exist.
01:40Thank you!
