Summary

Gabriele Carcassi argues foundational physics assumptions are backwards in his Assumptions of Physics project. He examines the bridge between mathematics, physics, and philosophy, covering topics from real numbers to the quantum‑classical divide and the role of open‑source frameworks.0:00 Intro0:22 Gabriele's Channel3:13 Assumptions Project6:06 Physical Mathematics9:38 Real Numbers13:06 Ensemble Space16:38 Classical Mechanics19:00 Additional Assumptions21:26 Classical vs Quantum23:19 Entropy & Symplectic25:07 Jaynes & Thermodynamics30:25 Units in Physics33:21 Math vs Physics37:07 Planck Scale Structures41:51 Theory Applicability1:16:25 Engineering Background1:18:04 Physics-Math Bridge1:19:01 Assumptions Project1:21:08 Grant Funding1:23:05 Mechanics Critique1:24:25 Problem Identification1:25:03 Publishing Challenges1:27:03 Engineering Approach1:29:03 Practical Implications1:33:28 Measurement Problem1:37:05 Classical vs Quantum1:43:04 Integrating Math Physics1:55:07 Current Projects2:04:43 Future Goals2:07:03 Open-Source Framework2:10:57 Support TOESPONSORS:- I personally subscribe to The Economist.

0:00.0	Just following blended mathematics, and I think we're just losing all the physics we have for physics backwards as what it should be.
0:06.0	Because all the math and we do are point set topology, our differential geometry, all that.
0:12.0	You start with points, and then you define incintesimal things on points, and then you integrate.
0:18.0	But that's not what we do in a lab.
0:31.4	When did we first get in contact? Oh, geez. I don't remember. It must have been more than a year ago, yeah.
0:38.8	Okay, well, I've been following your channel for approximately one year. I believe I contacted you shortly afterward.
0:44.2	Okay. Yeah. And you have a fantastic channel people should know about. So it's called the assumptions of physics, or at least that's the project name. And Gabriel's going to take it over
0:48.2	at some point and give the elevator pitch, the five-minute version. So a long elevator,
0:52.3	it's Seen Tower or in Toronto, that sort of elevator.
0:55.7	What makes your channel different is that you focus on the equations and the rigor,
1:00.7	and many people who are into demonstrating that some conventional aspect of physics is incorrect.
1:06.2	If they're in the academy, they do so from the philosophy of physics angle,
1:09.7	so maybe some interpretation of quantum
1:11.3	mechanics. But you don't focus on that. You're much more about demonstrating with line-by-line
1:17.6	proofs. In that vein, you remind me of Jacob Berandas, and he's from Harvard, and you're based in
1:23.8	Michigan. Well, I'll list some examples for people who, if you just want a teaser of
1:29.5	what's to come, why is it that Heisenberg's uncertainty or some analog of it is already in
1:35.6	classical mechanics under the proviso that you have to assume that thermodynamics is true?
1:41.9	Another is that the action principle, which the way that I thought of it is
1:45.8	a compression mechanism, so it encodes several different equations inside, and then you unpack it
1:51.3	with Elyla Lagrange's equations. But you show the action principle itself has a geometric meaning,
1:56.8	and the idea that you can translate between Newtonian mechanics and Hamiltonian mechanics and Lagrangian mechanics is false.
