Or maybe, rather don't read it. This book was not written by Richard Feynman, but by Ralph Leighton. This is hinted at by "Adventures of...

No. That's not how the MWI works. In the MWI, all possible outcomes occur, each in its own branch of the wave function. It's not even...

It seems to me that what changes is the rate of change of the phase, not the phase itself. I guess the most direct interpretation of...

Are you sure? It is true that you can factorize ##\partial_t^2\phi=c^2\partial_x^2\phi## (1D-WE) into...

There is a Q&A at the end, starting at 49:19, which contains stuff not contained in that transcript. Below, I collected how I tried to...

A multi-photon absorption might happen I think under extreme conditions like a strong laser.

Yeah, but in physics it typically arises because of probabilities, and how to interpret them.

The Dirac equation is beautiful!

The probability of rain today at 13:00 (where I live) is 20%.

This is how Ballentine presents the statistical interpretation--the ensemble is basically the abstract set of all instances of a given...

Why do you think that I see an ensemble of particles? I see an experiment depending on some knobs, that I can repeat as often as I want...

And another possibility it to try to understand what we are doing, currently. Like the article mentioned in the OP. Or also David...

That is not the point. You construct issues and complications for the minimal statistical interpretation where I can see none. Somehow...

Although well thought of by many, including me, it is not an orthodox approach. That said, it is the book I recommend studying...

If you compute the scattering between two incoming particles, or the lifetime of some excited state, then you are looking at a simple...
