#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

And you put all these over here because you want to see how they deflect and bend through it.

#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

But you put a control in the experiment.

#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

But you basically put glass plates back here.

#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

Because obviously, everything should just deflect, but nothing should bounce back.

#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

So, it's a control in the experiment.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

But what did they see?

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

They saw things bouncing back.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

Like, what the hell?

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

Like, that fit no model of any idea, right?

#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

But Rutherford, like, refused to, like, ignore what was a clear... Like, they validated it, and he sat down, and based on classical physics, he made the most extraordinary discovery, which was the nucleus, which is a very, very strange discovery.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

What I mean by that, because what he could figure out from this is that in order for these particles...

to bounce back and hit this plate, they were hitting something that must be heavier than them.

#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

And that basically something like 99.999% of the mass of the matter that was in this gold foil was in something that contained about one trillionth of the volume of it.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

And that's called the nucleus.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

And until, and you talk about, so how revealing is this?

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

It's like, this totally changes your idea of the universe because a nucleus is a very unintuitive, non-intuitive thing.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

It's like, why is all the mass in something that is like zero, like basically it was the realization that matter is empty.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

It's all empty space.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

And it changes everything.

Until you had that, like you had steam engines, by the way, you had telegraph wires, you had all those things.
