But the point is, you'll see the exact same things. From New York City, you can see them. From the middle of London, it doesn't matter where you are. If you have a clear sky and the moon is out, you'll see the same thing. But when you look at Jupiter, you'll see these four dots.

And here's where Galileo just had this otherworldly intellect that, you know, when I saw those, I was like, oh, cool, it's next to some stars. Until I realized, I had to do more research, that those are actually the moons of Jupiter. So in one night, tonight, you can, you know, quadruple the number of moons you've ever seen in your life. And some of those moons are almost the size of our moon.

Our moon is unusually large. Those moons sometimes will cast shadows on the – so it will be an eclipse. You will witness an eclipse on Jupiter on another planet with this $50 instrument or whatever, OK? When he was observing these things, he would do things that were not only psychological and they were therapeutic for him in his later years. I will explain that in a minute.

He ended up going blind and so losing the sight and kind of the recollections that he had and he lost his daughter. It was a nun because he was – she was illegitimate as most of – I think all of his kids except maybe one, his oldest one. He had mistresses. He was married, divorced basically and I was kind of like – he was Catholic in Italy, primordial Italy basically.

It didn't exist as a country but he was in Tuscany. And he had a lot of challenges. He was almost always broke. Even when he invented his version of the telescope – again, he didn't invent the telescope. But he made it so much better. 10x'd it. 20x'd it. Zero to one. It was incredible what he did with it.

He realized this is great and all for me to discover these cool things and learn about the universe. He was deeply religious too. But I got to make money. I got to pay for my house. He had like – imagine like your students at Stanford are living with you because that's the only way you can afford to pay rent in your – I mean – and you're cooking meals for them. They're like slobs, right?

I mean like – I was a slob in college, right? So the point is he had bills to pay and he was a businessman. He realized, well, look, if I start making these telescopes, everybody will see the things that I'm seeing. I won't have any monopolistic advantage over Kepler, who is his friend but also his competitor.

They were really vying for who is the best astronomer of all time, Kepler in Germany and obviously Galileo in Italy, well, become Italy. And he realized Kepler was purely theoretical. He had great math chops. He came up with functions for the orbits of planets before Isaac Newton proved that they came from calculus and universal gravitation. Incredible scientist.
