Of the three books I was thinking about (~$41 on Amazon), that is book 1. The other two are: <strong>Quantum Mechanics: The Theoretical Minimum</strong> (Feb 25, 2014) and <strong>Special Relativity and Classical Field Theory: The Theoretical Minimum</strong> (Sep 26, 2017). Read with a highlighter, doodle in the margins, think about it while walking the dog...
I am the guy who argues about tensor/linear algebra. I am actually the quaternions guy, the owner of quaternions.com since 1997. Quaternions are just numbers, tensors of rank 0 like real and complex numbers, so they completely blow off any and all indexes. Gauss invented both tensors and quaternions, but he only published the work on tensors and sent his student Riemann to his hard road of glory that formed the basis of GR. I am claiming Gauss made the wrong call: numbers should rule mathematical physics, not Reimann geometry.
Susskind has lots of YouTube videos up. I am in MA, so the wrong coast to visit. I am mostly a fanboy of the clarity of his vision. I need to return to the QM book and translate more into quaternion series Jupyter notebooks (I only completed 3/10 chapters).
The goal of physics is to explain SSIN (Simplest Shit In Nature). Simple stuff knows how to do quantum mechanics, no black holes or wormholes needed. I am the guy who wondered: if I cut out the past lightcone, what sort of physics would result? Really, draw a dead dull picture Minkowski space-time, cut out the past lightcone and then deal with the result.
