“Symmetries of Time”

Time is a basic element in our models of the physical world, as is symmetry. Several issues at the frontiers of modern physics concern the interplay of those concepts. Elaborating on this theme, I will survey the current state of axions and time crystals, including very recent work.

[@josephhardin8391]

I absolutely love Frank Wilczek's work. I hope anything I make, he'd review.

[@chriswhitt6685]

The axion story is priceless. Fascinating

[@mpcc2022]

What is e dot b? I'm still studying Physics and I haven't gotten to QCD. I recognize dot meaning the dot product of energy and b, if e even stands for energy in this context I'm not sure, but e dot b was not discussed in electrodynamics at my school. Clarification please 🙏.

[@zaidsserubogo261]

Time symmetries: 1- translational time symmetry which describes the polynomial linkage of displacement inform of equivalent time. 2- transformation time symmetry describing the polynomial linkage of displacement in form of reversible time. 3- the transformation symmetry of time describing the polynomial linkage of displacement inform of reducible time. The detailed physics of that complexity is relative in nature

[@ares12265]

The only thing that can be added is that it can be distributed.

How do time crystals interact?

I've never seen Dr. Who. Will it be on the exam?

Lenny is very active ...hahaha

[@BarriosGroupie]

I don't understand why, after the discovery of relativity, physicists still wanted to believe that physics is time reversible. PT reversibility should have been expected to take its place IMO.

[@dugudr]

I’m not physicist or a Christian but whatever they’re talking about the first thing need attention is the dark space. Specifically the space around the screen which is completely useless shoulda get a better zoom lens.

[@davidwilkie9551]

Time reversal symmetry applies in the particular, interference and coincidence in-form-ation of particles, phenomena that occurs in part, eternally. "Beat" frequencies.., (finite-quantum limit of uncertainty? Axion? In a specific circumstance), ..all phenomena of frequency is a compound pulse that adds up to the Universe, and have interesting examples of double-multiple digital beats, ..like heart beats and Time Crystals? The ground state of the Universal harmonic oscillation is QM-TIME, the almost static metastable existence of probabilities in possibilities that is also interpreted as the Holographic Principle.

I can't make heads or tails of that. Is that what the talk sounded like to someone who didn't know most of the words used?

[@davidwilkie9551]

@@JohnDlugosz pretty much, it's having a go at restarting the talk in plain language, (or I would if there was a suitable set of words available), but first reinterpret what the speaker said from another point of view.. I have to accept that the lecture is on topic and everyone else knows what the contents mean to their perceptions.., and then make no intentional criticism of what I don't understand about what they believe. Ie, assuming they have the very best of reasons why the presentation is correct. (Nobel Prizes are the assessment of knowledgeable people in the field) I think it reasonable and rational to support the lecture and add any complimentary observations, on the same basis, that it's the job of anyone who watched the video and naturally wants to think their own thoughts to decide for themselves, what is applicable to their own understanding. In no way is this approach other than parallel, so that should be obvious..

@@davidwilkie9551 The same comment applies to this new response, too.

[@garyoldham4449]

Trippy! Thank you all for your contribution! Lol!

All Time Crystals disappeared during the experiments.

I smoked them.

sounds to me a quantum computer set to idle could in a sence discover dark matter

[@garyoldham4449]

Yes, but only with the right power supply. Don't skimp on the power supply!

[@orange70383]

This guy doesn't seem to be genuine, kind of planted I'd say.

[@garyoldham4449]

Or perhaps the exact opposite. Extremely genuine while also perhaps, to some degree, unplanted. Well, historically science has not been planted in 100% truth so I take all with a grain of humility including myself. So my theory is, we are all wrong. To some percentage.
