All right, Clyde.

Clyde Tombaugh.

- Yeah.

- Discovery of Pluto.

- Pluto, yeah.

- Yes.

- Named for the Disney character.

- He really did name it after the Disney character.

- Well, actually, Pluto is the god of darkness in Greek mythology, so he's using that as his escape thing.

- All right.

- So it's maybe not such a big deal anymore because it happened so long ago, but it was a big deal when they figured out, "Hey, we got nine planets now."

- Really big deal because the orbit for Pluto is 247 years.

So the chance of a person's lifetime fitting in the very small window that it was visible-- - Yeah.

- Was pretty small.

- And then now they say it's not a planet.

- Well, it's a sub-planet or dwarf planet, but the Streator kids wrote letters trying to make sure they got kept it as a planet.

- It's a planet.

- Close enough for me.

- Just, yeah.

Did you hear where they say now the planets weren't like collected, they were actually birthed out of the sun?

- Did not hear that.

- Yeah, well.

- Was that in the paper yesterday?

- Google it.

- Okay, Google it.

- So it had to be pretty cool.

I mean, did you meet-- - I met Clyde.

Yeah, I met him, you know, I was writing letters to him when I was in fourth grade, and then in sixth grade he came back for a family reunion and had his Edsel and he said, "Larry, come on here."

- [Rob] He had an Edsel.

- Yeah.

- [Rob] Of course he did.

- He did.

And he came over and said, "Hey, Larry, come here.

I want to show you something."

So we looked in the back seat of his car and he had round circles in brown paper and opened them up and he said, "What do you think those are?"

And he said, "They look like hunks of glass to me."

And he said, "Well, they are, but they're lenses.

I'm making another telescope."

In his lifetime, he made about 14 telescopes.

- [Rob] Oh.

- Most of them are still in the Smithsonian.

They bought them.

- So probably back in the day, these were-- - Pretty rare.

- Yeah.

- Pretty rare.

- Okay.

- But this one was one that he was making.

And I said, "Well, how do you get the curvature right?"

And he said, "Well, it's really scientific.

I take a Campbell soup can and I put the smallest hole I can in it, and I put a light bulb 27 feet away.

And when I can get all the light to go through those lenses, I've got the curvature right."

- See, everything's.

They overthink everything these days, yeah.
