How to pronounce “classical physics” in English

Because classical physics is profoundly counter-intuitive.

According to classical physics, the energy of an electromagnetic wave depends only on its amplitude, not its wavelength or frequency.

Determinism versus non-determinism-- classical physics is deterministic.

Now in a classical physics way of thinking, it's either one or the other.

It does not happen in classical physics.

We want to account for classical physics, the physics of Isaac Newton, using quantum physics.

The logical foundations of quantum physics require classical physics.

So, in classical physics, the solution is simple.

The book is about all sorts of ideas in classical physics.

After Einstein fixed gravity, all of classical physics obeyed this important rule.

It was developed to explain situations that we couldn't explain using classical physics.

From quantum thermodynamics, we've gained fundamental insights into what separates quantum from classical physics, what it means for time to flow,

physics-- again, as Niels Bohr and company said-- then we can't ground classical physics in quantum physics.

And that seems really strange, especially because there's nothing particularly special about classical physics.

In a second theorem, Noether proved that for these local symmetries, you no longer get proper conservation laws like we're used to in classical physics.

because they're based, really, on quantum physics and non-classical physics.

So right now, if I want to use Newton's physics, the pre-quantum classical physics, to figure out where this marker is,

Bohr and Heisenberg, they said things like, oh, the idea of measurement has to be grounded in classical physics because that's the way our intuitions work--
