comment Is there a thermodynamic limit on how efficiently you can solve a Rubik's cube?
@IlmariKaronen Okay, yeah, I think that sounds convincing. Thank you.

Sure, but the question is, supposing we are not going to record the information on a second cube (or anywhere else), can we then justify the conclusion that the machine must give off heat?

How do we know that it is impossible to solve the cube without recording the position in the machine's state?

comment Alternate young double slit experiment
The question isn't clear to me. Light comes from a laser, hits a screen with a small circular hole, goes through the hole, then hits a second screen. The second screen is solid, and we observe the interference pattern on the second screen? Is that the entire setup? If so, you will see an Airy pattern.

comment Conservation of angular momentum in a free rod
@BillN My first response had a typo in the figures which led to some back-and-forth which I deleted as unproductive.
