"Veritasium" (YT) - "The Big Misconception About Electricity" ?

<< < (254/396) > >>

TimFox:
The establishment still scoffed at relativity in 1921, so the 1922 prize awarded to Einstein was for his explanation of the photoelectric effect. 
This effect was one of the famous experimental results that could not be explained by classical physics.
His explanation involved photons, electrons, and equations.  The equations still explain the quantitative aspects of the photoelectric effect.
The history of science is interesting, but should not be confused with the body of physical theory now in use.  During the inter-war period, there was a lot of controversy and polite (usually) discussion between the leading natural philosophers of the day, involving both actual experimental evidence and thought-experiments.  Einstein's point of view was opposed to probabilistic explanations ("God does not play dice").  Usually, the adult in the room during these arguments was Neils Bohr.  (Bohr's original explanation of atomic energy levels motivated further theoretical development by Heisenberg, Schroedinger, and others, and is no longer used in its original form.)  Thus, science progresses.
I am not very religious, but I share Einstein's credo:  "Raffiniert ist der Herr Gott, aber boshaft ist er nicht."

More likely Lenard's explanation. Stolen by Mrs Einstein. And the equations here too were probably hers not his.
And i suspect that a proper explanation might involve my electons, i will have to have a good think.

Ahh. This explains why you admit your cluelessness about QM. You should leave photons and electrons alone though... basically all of electricity.
--- Quote ---The Dark Age of Science i think began with Einstein's STR. It got worse year by year, eg he got a Nobel in 1928 or something. Although it didn’t really begin until after he died, ie when experiments & measurements became much more accurate. And the Dark Age of Science will die when experiments & measurements get super accurate.

Please... stop... I can't take this level of comedy.  :-DD

I think i am starting to see. So, free photons & electrons are QM wave-functions, & electricity involves a jellium sea of wave-functions that drift along in a wire.
What does QM say about magnetism around a current in a wire? I mean re explaining what magnetism is, not how big it is.
How would QM explain my electon?

Anyhow, who was it that said that anyone who said that they understood QM didnt really understand it? Was it Born or Bohr?

Wow. This reminds me of a book I read (part of) years ago when I was spending time in a Barnes & Noble many years ago: There Are No Electrons: Electronics for Earthlings, by Kenn Amdahl. I think I'm going to order it and give it a re-read.

They would invent some kind of excuse. In fact they are so clever that they would have no trouble finding a way to use that excuse  to once again prove Einstein.

This has got to be my favorite flavor of conspiracy theory: that a bunch of scientists all agree to the same lie. Obviously, you don't know any scientists. All they want to do is be the first to find something new. (Just like you, except you're not a scientist.) There's no way you could keep each of them from secretly publishing their own paper and getting all of the glory. The premise is laughable.
