The question then boils down to how local is local? If you place two objects inside the space station, one a short distance above the...

It looks like one of those questions where someone who knows very little physics has thrown some numbers into a vague problem statement.

That's the least of one's worries. We are given the velocity of the balloon as 12 m/s. What is the direction of that velocity...

That said, it looks more like "advanced physics homework". The problem is in the expectation that it's something for a physics journal...

Despite his sales pitch, his idea is just computational. He saying he has a better way of doing some calculations. If his way of...

Wrong. He did a long apprenticeship with Sir Humphrey Davy (president of the Royal Society, world famous chemist) before his work on EM...

I'm not really convinced that what is being called the traditional method isn't starting from a different set of PDEs. In other words, I...

Yes to the "manipulated part". No to the "faster" part - that is, his algorithm is faster. He is claiming that of the two software...

I think OP could have a more productive discussion by posting in the relativity subforum using the homework template. It really sounds...

A horizontal speed of 200m/s seems excessive for a "block". That said, who cares?

He defined time in a particular kind of coordinate chart (an inertial chart with orthogonal axes) that way. But that definition is...

Hi all, I'm Mike, about to start teacher training in the UK. This forum seems good for finding answers to tricky questions especially...

Perhaps you could pass an undergraduate QM exam, but there is a gulf between that and doing new research.

And George Green was a miller from Nottingham who did ground-breaking work in mathematical physics in the early 1800's. That was 1800...

The noise-to-signal ratio is extremely high these days, where anyone can publish anything, for example, on academia.edu. Peer review is...
