This is a fascinating phenomenon – but fully within current theory. And there's no "inversion of the arrow of time", despite what the sensationalistic, misleading title seems to imply. From the recent paper (my emphasis):

Our results, over a range of pulse durations and optical depths, are consistent with the recent theoretical prediction that the mean atomic excitation time caused by a transmitted photon (as measured via the time integral of the observed phase shift) equals the group delay experienced by the light.

The theoretical explanation is given in this paper:

We examine this problem using the weak-value formalism and show that the time a transmitted photon spends as an atomic excitation is equal to the group delay, which can take on positive or negative values.

It is essentially related to the difference between phase and group velocity of waves.

One more example of how nature – as we currently understand it – offers amazing, fascinating, unexpected phenomena. It doesn't need misleading sensationalism.

Fully agree.

It's worth posting the blog post you linked.

Personally I disagree on value of sex/nude scenes – but it's a subjective matter of course. Your final argument is absolutely fair and logical, and very general too. Extremely well put – I subscribe 110% to it!

It's utter bullshit from the very start. First, it isn't true that the Ricci curvature can be written as they do in eqn (1). Second, in eqn (2) the Einstein tensor (middle term) cannot be replaced by the Ricci tensor (right-hand term), unless the metric is zero (even in flat spacetime the metric is not zero, it is the identity matrix). They nonchalantly do that replacement without even a hint of explanation.

Elsevier and ScienceDirect should feel ashamed. They can go f**k themselves.

It seems to me these scenes are introduced in films to sexualize them. Most often than not they don't add anything to the story. But blood & sex get more viewers. So I find the whole thing hypocritical.

Brings me to mind an episode of the hilarious series "Coupling", where Jeff says that the actress in the film "The Piano" (?) was naked in the whole film. His friends say she wasn't, it was only a scene in the film. And Jeff replies "it depends on how you watch it" 🤣

Agree 110%! It's sad because it pushes back those people who were curious about alternatives and were willing to try. Hopefully things will improve with time...

I've tried different clients: Element web, desktop, and android, and FluffyChat desktop and android. The problems seems to come, as other have written, when the matrix.org server is involved: it's people from their handle there which experience glitches joining rooms in other servers. It seems this "part" of the fediverse still needs a lot of development.

Looks very promising! thank you for sharing. Seems worth trying and supporting.

I didn't know about !matrix, cheers!!

Which can be further summarized: academics (🙋🏻) are basically a bunch of idiotic sheep, despite being in academia.

Fantastic, this is extremely helpful, thank you! 🥇 I wanted to test a couple of distros for my Thinkpad, and I'll make sure to check and save this kind of information from live USBs.

Thank you, that's useful info, I didn't know about this. Could you be so kind to share some link, or say something more, about lspci and lsmod and how to proceed from them to identifying which drivers one should install? Cheers!
