This is CBSI on the world. I'm John Batchel with Matthew Shendell, the historian, curator at the Smithsonian National Air and Space Museum,

a really cool job, and the book is really cool.

For the Love of Mars is about human history and the Martian planet, projections, interpretations,

and now science.

Matt Descartes died 1650.

Christian Huygens.

Giovanni Cassini died 1712.

Isaac Newton died 1726.

These men, Leonard Euler of all physics, these men put together what we understand to be science,

following Galileo's groundbreaking martyrdom to what he saw through the telescope.

All of this is going on simultaneously with them inheriting the old world.

Were they seen as rebellious of the ancients when they provided these interpretations of observation and mathematics?

I think yes and no, right?

Galileo didn't see himself necessarily as being rebellious.

He thought he was still working within that same tradition, but trying to modernize it based on, you know, new observations, new mathematics.

Now, I don't want to try to get too deep into what Galileo really thought he was doing, but at least this is the way that he would describe it in letters that he wrote to his patrons.

And, you know, Galileo's observations of the moon certainly gave people a reason to think that there was something different going on in the heavens
