Paradigm Shift, Ghost Particles, Constructor Theory | Chiara Marletto

Chiara Marletto, a theoretical physicist, discusses the innovative principles of Constructor Theory, a groundbreaking approach that shifts the focus of physics from traditional dynamics to the realm of possibilities and impossibilities. She explores its applications in information theory, thermodynamics, and the fundamental understanding of life, highlighting how this theory could revolutionize our perception of reality and quantum mechanics. Her insights blend deep scientific knowledge with a philosophical perspective on the nature of discovery and the endless pursuit of knowledge in physics.

How pleasing that the conversation gets to the meat the first second of the video, great stuff Curt.

[PaulCourtney]

I was so amazed at Chiara's ability to pivot so easily from topic to topic and be able to explicate how constructor theory addresses different aspects of physics. And the gem unearthed at the end, that Chiara had first followed her love for languages and the humanities before pursuing physics, provided the explanation for the ability to explain how constructor theory addresses (or doesn't) so many areas of science. For me, who studied physics long ago, listening to this conversation was like eating a sumptuous and immensely satisfying meal. Thank you both!

[brettw]

So unbelievably clear explanations of extremely esoteric concepts! I’m blown away. I don’t think I’ve ever heard a better articulation.

[dubbrain]

Sono estremamente fiero di vedere una torinese intervistata da Curt! Grande chiara! Fantastic conversation

[elodvezer]

Thank you Chiara. Thanks again Kurt! 👍🏻

[tejaK]

Briliant. Thank you so much, Chiara and Curt.❤🙏❤

@1:20:00 Curt's analogy to the Aharonov-Bohm effect was good and apt. You have to bear in mind the field variables are themselves not _the_ particles, they are instructions for transformations of the other mathematical objects representing the observables (linear operators). So all the gauge redundancies can be possible transformations needed to model a given measurement. If a measurement is sensitive enough, especially to interference effects from entanglement, then the "non-classical" degrees of freedom can be perhaps discerned. But they are not elementary particles _per se_ they are just instructions for transformations. The particle phenomenology is what underpins those transforms (why we'd need to apply them in our model). Weakly analogous are Nambu-Goldstone bosons which are also a bit ghostly.

Very nice discussion. Straight to the point, and pure physics

[liminally-spacious]

I really enjoyed this! Chiara speaks so efficiently and elegantly, her intuitive grasp of these concepts is palpable. I especially enjoyed the brief dive into the episteme behind No-Go theorems. I agree that they seem to hold with a high level of confidence and seem quite ontologically primitive. Great questions, Curt. You really put effort into preparing and understanding your guests' work, which shows in your rich interviews.

[garretthorsch]

Keep em coming Kurt. I know there aren’t many people out there who come into these types of topics trying to take them seriously. So the fact that you do always keeps me coming back. Especially on the UFO topic. Its clear there is something strange happening and the government might be behind some of it but definitely not all of it. Anyway I appreciate you

[christineliang]

I like the discussion @20:19 about the subtle difference between "physically possible" and "trajectory likely/probable" by Curt and Chiara.

[petershelton]

Chiara Marletto what gem you are giving hope to science in stagnation for 100 years Thanks Curt❤
I learned a lot about how to couch my punny knowledge of quantum physics 😂

[williamjmccartan]

This was awesome, even for a caveman like myself, thank you both Chiara, Curt for sharing your time and work what a wonderfully expansive conversation, peace

[RSCa]

Bridging the languages of quantum and classical has now captured the imagination of poet's among us. This is a really good sign. Thank you.

[blijebij]

Great interview, loved it, thanks. Her look on ghost particles is very interesting!

[giorgioacccc]

Curt, you amaze me more day by day. Thank you for work!! :)

[eriklintsev]

Amazing conversation❤also makes me think of Wolfram

[christineliang]

My gut feeling told me this opened up a new way for doing physics, and it's gonna be fruitful. How I wish I could be part of this progress.

[kathleenrosenberg]

Fantastic! I love the way you prepare & can ask such great questions. Imagine anyone else trying to interview them!!
