The fact that clocks are synchronized differently in different Inertial Reference Frames is the basic result of the relativity of simultaneity. The fact that the time difference is equal is due to symmetry. Those are different statements due to different logic. But if you look carefully at the...

You refer to this, but I'm not sure you realize how it works in this scenario. It refers to the synchronization of the clocks within the two trains' Inertial Reference Frames (IRFs) being different. Each train thinks that the clocks along the path of other train's IRF are synchronized incorrectly.

I'm not completely clear on the scenario (probably my fault), but you are correct that the time dilation is the same regardless of the direction of the relative velocity.

I over ate. ?

You'll like retirement if you like things like this. AI-generated code is great for fun things where the consequences of an error are not severe. As the severity of a coding error increases, my concern increases.

Nothing personal. I know nothing about this subject, but I am very skeptical, in general, about the current wave of AI LLM efforts. IMO, any AI LLM results require very careful review.

This may say more about cheesecake than it does about the birthday problem. ;-)

ANYTHING that relies on unfiltered internet "knowledge" is on very shaky ground.

Don't worry. None of us are. :-)

The accuracy of the theory's predictions have been verified to astonishing accuracy up to the current day. GR adjustments are included in the GPS devices that we use every day. Without the GR adjustments, GPSs would be unusable. You may want to interpret the theory in different ways and there...

RIP, Margaret Hamilton. She died on Sept. 30, 2026, at the age of 90.

That's fine. But if you ask a physics forum for a numerical answer, you should state those assumptions. In the real world, you give them the 2 platters and tell anyone who complains to shut up. ;-) At least that is what I would do, but I have very few friends. ;-)

Have you stated the problem completely? 1) Are the varieties equally likely to be wanted by people? If not, I don't think this can be answered. If everyone wants the same variety, there are not enough of that variety, so the answer is 1. 2) Are there two of each variety on each platter? 3) What...

The drive shaft is the most vulnerable part of any computer. ;-)

Certainly, for any fixed number, n, and any multiplier, M, n is more than M times far away from infinity than it is from 0. If this is your thought, you might be better able to answer your question. Are you asking what it implies or what it literally means? I expressed what I think it...
