Matterwave's latest activity

Yes, because it is massless.

Just to give a 1-sentence answer: the frequency of light is observer dependent.

Not sure why you bring GR into this and not sure why you bring photons into this. The measured frequency of waves depend on relative...

If you go with the L+L derivation you only need to prove ##ds^2=ds'^2## because ##ds'## is arbitrary. Note the quote "in any other...

By analogy, "homogeneity of time" would mean invariance under time translations. And "homogeneity of space and time", which is what...

If the potential in the box walls has only a finite width, yes.

Imagine I say "this piece of clay is homogeneous" what would that mean? We can look at the density ##\rho## and conclude that ##\rho...

I think that's reasonably standard terminology, yes.

Unfortunately you can not resolve a logical contradiction via boundary conditions.

To resolve this problem, Born-Von-Karman boundary conditions is used.

This is a self contradictory statement. A particle can't be everywhere and also confined to a box. :) Food for thought: if you have an...

Yes, this much is clear. From a purely terminological perspective, I would call each ##\Delta## an "uncertainty" while the uncertainty...

"He knows, she knows" is an easy way to spin your head around in circles and not get anywhere. Relativity is non-intuitive but it...

That product is what appears in the quantum uncertainty principle. But each ##\Delta## by itself is not constrained by that principle...

You’re right. Actually, you are all right. I did my study, applied my reasoning and understood why the idea was wrong. Thanks.
