Like.
I'm interested in learning enough to understand relativity (and QFT). I studied physics in college (decades ago), so I guess I'm at a... -

It does if the state in between is not an eigenstate of the Hamiltonian. Then the state will change by time evolution in between the...

Matterwave replied to the thread Graduate Measurement and expectation value.A more complete exposition of the situation might require a really long post. Perhaps you could elucidate further your core question or...

Matterwave replied to the thread High School What Medium Does Light Travel Through in Space?.Do you want more of a solid mathematical foundation in differential geometry? Or just what's needed to do relativity? Or something in...
-
Matterwave replied to the thread High School What Medium Does Light Travel Through in Space?.Remember to use the metric to keep the indices in the right place. In GR this can bite. In SR this leads to some negative signs in the...

Matterwave replied to the thread Graduate Is the deformation in Eq. 56 really innocuous?.I have not read through the entire paper and just glanced around the relevant sections so take this with a grain of salt. My...

Matterwave replied to the thread High School What Medium Does Light Travel Through in Space?.I vote for "lights"... ##\frac{light\cdot \cancel{second}}{\cancel{second}}=light##

Matterwave replied to the thread High School What Medium Does Light Travel Through in Space?.It's an AI generated video of Feynman. Maybe his voice helps elucidate concepts. 😂

Matterwave replied to the thread High School What Medium Does Light Travel Through in Space?.Could you clarify what it was about @Ibix answer that brought you to this conclusion? For example, @Dale already brought up the fine...

Or, as I said, vary ##\alpha##, which would actually change ##c## in the sense you mean. But that just leads to the question of why...

Matterwave replied to the thread Graduate Measurement and expectation value.2 points. 1. You have to consider my answer in light of my longer explanation above. 2. That's not what the Ehrenfest theorem says...
