MMike_bb reacted to Dale's post in the thread Undergrad Proper Acceleration And Time Dilation with
Agree.
It doesn’t matter. Any unbalanced force will do. -
MMike_bb reacted to Matterwave's post in the thread Undergrad Riemann curvature of a metric defined with a coordinate basis with Agree.
No, the Riemann curvature tensor is a proper geometric object. It is only 0 if it is 0 in all bases. If it is 0 in one basis, then it is...

MMike_bb reacted to Herman Trivilino's post in the thread Undergrad Special Relativity - clocks on two trains with Agree.
The notation is confusing. ##\Delta t## is not a clock-reading. ##t## is a clock-reading and ##\Delta t## is the time that elapses...

Like.
Then with the spacial separation in trains frame you can calculate and show the invarience of the spacetime interval: So @Mike_bb is... -

I wouldn’t recommend trying to redo the same analysis with different numbers. I would do the following: Start with the left train’s...

Ok, thanks!

MMike_bb replied to the thread Undergrad Special Relativity - clocks on two trains.Dale explained what's wrong in my calculations. His explanation is the best solution.

MMike_bb reacted to PeterDonis's post in the thread Undergrad Special Relativity - clocks on two trains with Agree.
Yes. Didn't you just do that yourself? The stone is at rest in Frame X but moving in frame X'. The train is moving in Frame X but at...

Fictitious forces will appear in a non-inertial frame whether you call it "moving" or not. You don't seem to grasp that "moving" and "at...

MMike_bb replied to the thread Undergrad Special Relativity - clocks on two trains.We have big stone at rest in Frame X and moving train (Frame X'). These frames are moving relative to each other. Could you provide example?

MMike_bb replied to the thread Undergrad Special Relativity - clocks on two trains.I've mentioned it above. See comment #74.
