Yes....But. Certain classical ideas work incredibly well up to a point. Something like Compton's E= pc, Planck's E = hf, and a few more. They work incredibly well up to a point. Something like the observations in how radio waves behave when they're broadcast. But then holes begin to appear.
But, if you're building radio transmitters. For the sake of getting on with it, and building something that will work. You can treat your transmissions, as a wave propagating through a medium - or even a flux of light particles that can bounce around. Either approach will give you results that are in agreement with observation. You can even approximate how many light particles you're getting from your antenna, by how much power you're pumping into it. It's a good example of a how a theory can be in agreement with observation and still be wrong - all you need is one observable snag in the idea, and it's completely wrong.
The photon isn't a wave, but nor is it a particle. You have to strip away all these ideas. The state of a quantum system has a description that is not the same as the state of a classical system.
But any description of the quantum system should naturally emerge to explain the classical. Classical rules can't just be explained as broken down at a critical level.
I'm trying to hack my way through it, it'll take me a while, but I'll get there. But when someone says something like "Oh, there is no classical reality. It's all just a hologram, made of vibrating bits of string in hidden dimensions", they probably just given themselves just a little too much liberty.
But some of the things I've read, seem to me at the moment, just seem to be convoluted descriptions and not explanations of what is already observable. A guy with an radio transmitter could probably work out the probability of a photon scattering, reflecting, etc. He could work out constants and equation and if his name was Bob, he could call it Bob's Law.
I'd like to see equations where factors from QT slot neatly into classic equations. Maybe they're all there, I just haven't seen them yet.
I've just seen the Wigner function. Damn....it's going to take me a really long time to work through all this.
Damn damn damn damn.
