I've got the first of the explanatory videos up. Randy and I have talked about putting up videos to help explain what is going on in the experiments for almost a year now. It can be really hard for someone to visualize what's happening in the experiments for the paradoxes just from our description. I've even found that in writing descriptions: the more precise someone describes something, the harder it is for someone else to understand it.

That's just not how we talk.

Unfortunately, the vaguer the description the more easily the listener misconstrues what is being said. And it turns out it's not an easy needle to thread: it takes many years for someone to be able to reliably read a geometrical description of a problem without getting confused.

But never fear, video is here! I can draw out what I want to talk about for you, as I have in this video.

Measurement and Compensation

Unfortunately, I deleted much of the intro. I'll fix it later.

e-mail me if this is still here after September. Thanks!

In this episode, we talk about Aharonov and Rohrlich's Quantum Paradoxes, chapter 8: "Measurement and Compensation":

Please comment on our subreddit! It will help us respond to what you're saying if we can collect all the comments in the same place.

We're reading Quantum Paradoxes by Yakir Aharonov and Daniel Rohrlich. This is a technical book that is making an argument for a specific interpretation of quantum theory. The first half of the book uses paradoxes to explore the meaning of quantum theory and describe its mathematics, then after interpretations are discussed in the middle chapter, an interpretation of quantum mechanics is explored with paradoxes based on weak quantum measurements.
