#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

So, like, conjecturally, we have a good model of them.

Lex Fridman Podcast
#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

I mean, like, as I said, I mean, they have certain patterns, like the primes are usually odd, for instance.

Lex Fridman Podcast
#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

But apart from these obvious patterns, they behave very randomly.

Lex Fridman Podcast
#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

And just assuming that they behave... So, there's something called the Kramer random model of the primes.

Lex Fridman Podcast

That after a certain point, primes just behave like a random set.

Lex Fridman Podcast
#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

And there's various slight modifications to this model, but this has been a very good model.

It matches the numerics.

It tells us what to predict.

Lex Fridman Podcast
#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

Like, I can tell you with complete certainty the Trim-Priority Context is true.

Lex Fridman Podcast
#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

The random model gives overwhelming odds that it's true.

I just can't prove it.

Lex Fridman Podcast
#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

Most of our mathematics is optimized for solving things with patterns in them.

And the primes have this anti-pattern, as do almost everything, really.

Lex Fridman Podcast
#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

But we can't prove that.

Lex Fridman Podcast
#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

Yeah, I guess it's not mysterious that the planets are being random because there's no reason for them to have any kind of secret pattern.

Lex Fridman Podcast
#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

But what is mysterious is what is the mechanism that really forces the randomness to happen.

Lex Fridman Podcast
#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

And this is just absent.

Lex Fridman Podcast
#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

Oh, yeah.

Lex Fridman Podcast
#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

So it's a problem that you can explain.

#472 – Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

It helps with some visual aids.
