Can someone shoot down these ideas for measuring the speed of light in one direction?

I recently saw a Veritasium video on how we aren't able to measure the speed of light in one direction - only in two. He claims that...

Is Poynting's theorem derived from Faraday & Lenz law?

Is Poynting's theorem dependent on Faraday & Lenz law? It's an eloquent equation that shows the electrical to mechanical conversion (and vice versa), but I assume that it heavily relies...

Assumptions Involved in Circuit Derivations

When deriving formulae for RC, RLC, LC circuits, etc., we typically assume that current is steady. Griffiths gave a good explanation of why this assumption is reasonable (he states essentially...

Does the recent "3-sigma" result at LHCb account for the number of different tests of beyond standard model physics that have been done?

Recently there has been quite a lot of media interest generated by a reported observation of beyond-standard-model physics at the LHC with a "three sigma" degree of statistical significance. My...

What happens to the current when a wire is left open to air at one end?

I know that current is produced due to potential difference which makes the free valence electrons being passed on in a copper wire(or am i wrong, plz crt me if...
