Carlo Rovelli: Relational Quantum Mechanics and Scientific Realism
Вставка
- Опубліковано 15 кві 2024
- This lecture was filmed on 6/7/2018 as part of the "Lecture series on foundations of science: Scientific Realism" at the Faculty of Physics of the University of Vienna.
In it, Carlo Rovelli talks about the most popular interpretations of quantum mechanics, introduces his own called Relational Quantum Mechanics (RQM) and discusses the philosophical implications.
Here you can find Rovelli's original paper on RQM from 1996:

Thank you so much for sharing this. What an age we live in where we can watch lectures from amazing people from almost anywhere.
amazing lecture
interesting topics but a big pity for the microphone, often too distant, making words pretty confused :-(
Quantum Entangled Twisted Tubules:
When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else. Therefore, a "particle" is actually a structure which stores spatial curvature. Can an electron-positron pair (which are made up of opposite directions of twist) annihilate each other by unwinding into each other producing Gamma Ray photons.
Alpha decay occurs when the two protons and two neutrons (which are bound together by entangled tubes), become un-entangled from the rest of the nucleons.
Beta decay occurs when the tube of a down quark/gluon in a neutron becomes overtwisted and breaks producing a twisted torus (neutrino) and an up quark, and the ejected electron. The phenomenon of Supercoiling involving twist and writhe cycles may reveal how overtwisted quarks can produce these new particles.
Gamma photons are produced when a tube unwinds producing electromagnetic waves.
Grazie di Cuore!
I suspect the labelling structure of this event model is a mathematical dual of the branching structure of Many Worlds.

I was 11 minutes in and couldn't stand the audio. Thanks a bunch
Does the camera person have no idea that we might like to see what Carlo writes on the blackboard? WTF?
Modern pedagogy: using the Internet to show the backs of people's heads as they scribble on blackboards..
@@TheDavidlloydjones 🙄🙄🙄
Yea might be on to something with that looped gravity thing AKA looped time
The audio is distorted.
It’s much simpler than this really. I came here for the energy of understanding. 💕🦋🌈✨
Brilliant lecture - needs better sound

A follow-up comment. Northeastern University had plenty of guys like this in the 60s ... probably because that is all they could afford as a startup. Never appreciated sitting on huge classes listening to guys, like this, struggling with the English language.
1:08 can quantum mechanics explain that weird "collective" sound ?
No. It disturbed me when I came to the faculty. But then I got used to it.
@@denismijatovic1239 Did it disturb you that quantum mechanics can explain it or not explain it ?
@@Mandibil Haha. No. It disturbed me that people did that.
@@denismijatovic1239 Ok, but that is not an answer to my question ?
@@Mandibil The very first word I wrote was the answer. No, QM can't explain that. Stupidity can.
I very much like (actualy I LOVE) the basic ideas underlying Relational Quantum Mechanics. Alas : Rovelli doesn't do his work justice by this 'lecture' .
PLEASE prepare a more cohesive presentation the next time.
It's as if he was pulled from behind his desk while he was working on something else.
FINALLY at 43 min when he speaks about Heisenberg seeing a man walking in a dark park appearing intermittently in the park lights is when he gets to the heart of what RQM is all about. In "normal" Quantum Mechanics it is the MAN who is intermittently appearing that can be considered as a proxy for a quantum.
In RQM it is the PROCES of intermittently appearing ITSELF that is considererd to be a proxy of a quantum.
What also makes a bad impression is the fact that he often checks his wrist-watch.
great lecture, awfully taped and mic-ed
Not publishable.
Prof. Rovellli's staff, fans, and supporters do him no favours by allowing junk like this out in public.
You just resolved into my reality and we will together resolve into future realities as the google algorithm observes watch history. Quite strange.
This a badly made video: almost impossible to follow what he is saying since his voice is not clear and only a small fraction of his words are captioned. I'm sure his detailed context would be fascinating if I could understand what he is saying. I could understand the assistant professor clearly but not his mentor.
Cameraman and doundman is terrible.
Rovelli is trying his hardest to solve a non-existent physics problem and he gets exactly nowhere.
@Toasty MacNickels I am glad for you that you wasted so many words on nothing. :-)
If anything that's exactly what Rovelli isn't doing. He's saying there isn't a problem to be solved.
@@TheMahayanist The answer to that is being silent. ;-)
Rovelli may be the greatest minds in the field of quantum physics but we’ll never know because his terrible pronunciation, the massive variation in volume and an incompetent recording engineer have rendered his speech unintelligible throughout most of this lecture.
If they’d just run it through a compressor that would have been something at least.
You all are exaggerating these problems so much.
You can read his articles. I did. They are utterly boring and full of fluff. There is simply no there, there.
Of course Quantum Mechanics "works" because it's pure-math relative motion, Logarithmic Time Duration Timing perceived as sync-duration, ie exactly what is symbolically represented by the half-truth illusion of condensed matter and symbology.., aka The Measurement Problem.
If someone fully qualified to present the Holographic-Volumetric picture of resonant crystal formations as a logarithmic matrix in a Bose-Einsteinian Condensation video, this would be sufficient to fit into a Spinfoam-pulse bubble-modes Totality of ONE-INFINITY/Eternity-now Singularity wave-packaging of QM-TIME Completeness.
Same goes for CCC.
Word salad. And wtf has CCC got to do with it? Precisely nothing as it’s a classical theory.
