Train Fall Paradox A train is running on a long bridge over a river. A series of bombs planted on the bridge by terrorists explode...

##x^2-3x+3>1## ##x<1,2<x## for these area $$ \sum_{n=1}^\infty |\sigma_n| < \sum_{n=1}^\infty \frac{1}{n^p} ,p>1$$ so the sum converges...

FYI please share the plot of the sum as function of x which I ordered to ChatGPT.

I do not expect that learnig Hilbert space give you a direct answer to your question, but you may become familiar with mathematics of...

We are familiar with countable infinite dimension Hilbert space in QM. You may be able to get some hint for your problem from it.

Thank you @PeterDonis. I should be somewhat satisfied to know that studies are going on.

You may conclude that that statement, as you make it, is not even well-defined. You didn't specify a time in any frame at which B has...

In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$...

The first term has dimension of T^-1 though it should be non dimensional. You should investigate its derivation.

The author explains the figures saying "the point of view of S(or S′)". Therefore, there is a possibility that readers may...

I see. “The moving inertial frame against the original IFR” would eliminate those cases.

I was hoping that the name existed. :( The moving frame can for example rotate and its different points can have different velocities...

I do not think so. In the text, "(absolute) velocity of the moving frame" is better.

An example of my point. Say light is passing on element ##dx^\mu##, i.e., $$ g_{\mu\nu}dx^\mu dx^\nu = 0 $$ After variation of metric $$...

Yes. For $$g_{\mu\nu}= g_{\mu\alpha} g_{\beta\nu} g^{\alpha\beta},\ g^{\mu\alpha} g_{\alpha\nu}=\delta^\mu_\nu...
