If you want the opinion of someone who’s also self-taught in physics, though maybe not to the same level as you are, it’s the same as...

That’s the principle of relativity and it’s not Einstein, it’s Galileo from centuries earlier - Google for “Galilean transformations”...

Damn it, I did not read this post, just the first one. Ok so my crankometer just went off a little. Comparing yourself to Faraday and...

Sure. Physics has that pesky 'reality' thing above all, what makes a difference: those who did not prove beforehand to be able to walk...

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...
