Lucrezia Ravera, physicist at the Polytechnic University of Turin, joins to explain the dressing field method she's developing with Jordan François, and why she thinks the manifold itself disappears from the physical picture. We discuss Einstein's hole argument and the point coincidence argument, why gauge symmetry is a feature of physics rather than mere redundancy, and how a system as simple as two particles can act as quantum reference frames for one another. The conversation also covers relational quantum mechanics versus classical relationalism, why time and space variables vanish once you write physics in terms of fields on fields, and what it means to be a "first principle thinker" navigating a hyper-competitive, metrics-driven physics career. I hope you enjoy.FOLLOW:- Spotify: https://open.spotify.com/show/4gL14b92xAErofYQA7bU4e- Substack: https://curtjaimungal.substack.com/subscribe- Twitter: https://twitter.com/TOEwithCurt- Discord: https://discord.com/invite/kBcnfNVwqs- Crypto: https://nowpayments.io/donation/TOE- PayPal: https://tinyurl.com/paypalTOETIMESTAMPS:- - - - - - - - - - - - - - - - LINKS MENTIONED:- Lucrezia's Website: https://lucreziaravera.com/- Lucrezia's YouTube: https://www.youtube.com/@R3Fram3D- A Hundred Years Since Quantum Mechanics [Lecture]: https://youtu.be/UE0RKcnNdR0- On The Geometric Approach To The Boundary Problem In Supergravity [Paper]: https://arxiv.org/abs/2111.01462- Relational Bundle Geometric Formulation Of Non-Relativistic Quantum Mechanics [Paper]: https://arxiv.org/abs/2501.02046- Geometric Relational Framework For General-Relativistic Gauge Field Theories [Paper]: https://arxiv.org/abs/2407.04043- Lecture Notes On Symmetry Reduction Via The Dressing Field Method [Paper]: https://arxiv.org/abs/2603.29505- Stueckelberg Action: https://en.wikipedia.org/wiki/Stueckelberg_action- The Hole Argument: https://plato.stanford.edu/entries/spacetime-holearg/- Mechanics As A General-Relativistic Gauge Field Theory, And Relational Quantization [Paper]: https://arxiv.org/abs/2510.19845Guests do not pay to appear. #scienceLearn more about your ad choices.
