No, that's not really a useful way of modeling it for the case of light traveling through a linear medium.

The absorption/re-emission model implicitly localizes the photons, which is problematic


think about it in an uncertainty principle (or diffraction limit) picture: it implies that the momentum is highly uncertain, which means that the light would get absorbed but re-emitted in every direction, which doesn't happen. So instead you can make arguments about it being a delocalized photon and being absorbed and re-emitted coherently across the material, but this isn't really the same thing as the "ping pong balls stopping and starting again" model.

Another problem is to ask why the light doesn't change color in a (linear) medium


because if it's getting absorbed and re-emitted, and is not hitting a nice absorption line, why wouldn't it change energy by exchanging with the environment/other degrees of freedom? (The answer is it does do this


it's called Raman scattering, but that is generally a very weak effect.)

The absorption/emission picture does work for things like fluorescence. But Maxwell's equations, the Schrödinger equation, QED


these are wave equations.

What you say?!

I kinda assumed any Mars mission would include some simple centrifugal pod. Seems like even if it's just for sleeping it would be useful.

You know what you doing.

Dispersion and nonlinearities would like to have a word ;)

I could be wrong, but I think this could be due to how the states' suit is worded? As in, I think it's worded as, "you can't do that in our state," and not, "you can't do that full stop."

From another site:

Attorneys general from 18 other states also sued over the order in federal court in Massachusetts.

Brown [AG filing the suit] noted his lawsuit is similar, but said he felt Washington should lead a separate case because of “specific and unique harms that are brought here.” He also said that “we have a very good set of judges in our bench here in Washington, so I feel like this is the right place.”

(My emphasis.)

So, a good first step, and while this should be struck down in its entirety, my reading is that this was a lawsuit with limited scope, and the injunction matches the limited scope.

If he introduced the hobbits to breakfast burritos and breakfast tacos, I'm pretty sure all would be forgiven.

I would bet that if you remux BBB to an mkv and play that through JF, it won't transcode


I think it will just remux it back to mp4. Just a guess...

Interesting


I wonder if it only displays the first reason for having to mess with the stream, e.g., if it's really that it's an unsupported container, video, and audio codec.

Possible to try playing an h264 mkv (maybe Big Buck Bunny)? Since your screenshot is h265 I wonder if it indeed needs to transcode because that's unsupported (in addition to mkv).

unless everyone is using hardware acceleration

I think that's what (almost) everyone does. My little N100 works just fine with QSV.

Is it definitely transcoding? JF can remix without transcoding iirc.
