Re: New magnetic component discovered in the Faraday effect

We intuitively think in particles and see a world of billiard balls colliding with one another.

But actually everything is merely waves and fields.

There's going to be a time where humans finally reconcile the quantum with the newtonian -- and I can't wait for that day

Nearly 20% seems already significant, but 70%?! that's massive.

The two-slit experiment says otherwise.

The way I've always thought of this is there are potentials for interactions and interactions.

Interactions act like point particles and potentials for interactions act like waves.

Arguing over the distinction is a bit like debating whether people are the things they do, or the thing that does things. There is some philosophical discussion to be had, but for the most part it doesn't really matter.

Hmm? The double slit experiment definitely shows that particles are waves—weird quantum waves, but still waves.

That we're just collections of wave interference is wild.

what happens when you only send a single photon down the line though?

Nice to see a graph of % magnetic priportion and log wavelength going from radio to gamma.
