Physics

He's like a bumblebee.

Physics says they can't fly, but he can fly.

So he's in first now, and I would say he's pretty much a lock.

He's got a second in Bolido, and he's got 6,000 points from this international QS win.

I think there's a difference between, you know, what happened 20, 25 years ago and making a decision and sticking with that.

Physics, because of what?

The books that I was reading showed me the cool mysteries about space.

And not only that, there were some books then that I read by Stephen Hawking.

So in general, we want to understand how fantastic human scientists work and how one can then artificially recreate what those human scientists are doing.

We do this mostly in the domain of physics and in the domain of physics experiments.

Physics experiments are the one way how we can actually learn something new from the universe.

physics experiments is basically a question to the universe and from that question we get the answer those are the measurement results and this is how we can communicate with the universe in some way appropriate in some way there's basically no other way that we can get really fundamentally new things we can then interpret mathematically, all of your results.

[upbeat music] Hi, it's Ira, and you're listening to Science Friday.

Before there was what we call science, there was a term called natural philosophy, dating back to Aristotle, that explained basically the same principles we call science today: nature, physics, chemistry, biology, astronomy.

And I'm thinking about this now because my next guest, physicist and author Carlo Rovelli, has a new book called On the Equality of All Things: Lessons on Physics and Philosophy, and there's that connection once again.

And while it's a small book, there's a lot in there, from quantum physics to the nature of time, and I'm glad to have Carlo with me again.

Welcome back.

Thank you very much.

Major scientists were in- influenced by philosophers, and philosophy, um, was influenced by science in a larger sense.

Our philosophical view of the world, uh, was changed by Copernicus, was changed by Darwin when we understood we're, uh, cousins with, uh, all the other animals.

[laughs]

Physics sets the rules, even in your world.

Physics.

[laughs]

All right, so it, it all comes down to this.

Delivery available on qualifying orders.

That this order, however, might yield to convenience is plain from another book on the use of reason, where he says that Plutarch twits Chrysippus with inconsistency, because, in the face of this declaration as to the order of treatment, he nevertheless says that morals rest upon physics.

but to this charge it may fairly be replied that the order of exposition need not coincide with the order of existence metaphysically speaking morals may depend upon physics and the right conduct of man be deducible from the structure of the universe but for all that it may be advisable to study physics later Physics meant the nature of God and the universe.

Our nature may be deducible from that, but it is better known to ourselves to start with, so that it may be well to begin from the end of the stick that we have in our hands.

But that Chrysippus did teach the logical dependence of morals on physics is plain from his own words.
