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

I don't have the math, but doesn't quantum field theory say this?

There's no problem reconciling the quantum with the Newtonian. Quantum mechanics recovers Newtonian mechanics in the appropriate limit. The problem is reconciling the quantum and the Einsteinian.

But there’s no quantum explanation of gravity, right?

There’s no explanation of gravity, quantum or no. There are merely descriptions.

> But actually everything is merely waves and fields. The two-slit experiment says otherwise.

Another interpretation of the double-slit posits a guiding 'Pilot Wave' separate from physical particles... aka DeBroglie-Bohm Theory or Bohmian Mechanics.

Apparently it's not popular among professional physicsts though John Bell investigated it a bit. Einstein had some unpublished notes in the 1920s about a "Gespensterfeld" (ghost field) that guided particles.

Born was influenced by this 'Ghost field' idea when he published his famous interpretation of the 'Wave Function' |Ψ|^2 as a probability rather than a physical field.

Actually, Newtonian gravity can be added to QM and work perfectly well. It's GR gravity that doesn't work with QM, especially if you try to model very high curvature like you'd get near a black hole.

Maybe think of it as binary(particles) vs analog(waves).

Pilot wave is still my favorite - I don’t really believe it, but I like the image

Quantum Electro-Dynamics (QED) is the application of Special Relativity (non-accelerating frames of reference, i.e. moving at a constant speed) to Electromagnetism. Thus, the issue is with applying accelerating frames of reference (the General in GR) to QM.

Isn't everything descriptions, in the end, aka models? Turtles all the way down...
