2022-02-10: The Nature of Space and Time AMA
- 00:03: ... the laws of physics don't care about the direction of time okay so newton's mechanics even you know the equations of uh relativity even the schrodinger ...

2021-11-02: Is ACTION The Most Fundamental Property in Physics?
- 05:00: ... you study Newton’s mechanics and then move on to Lagrangian mechanics, it seems almost like a ...
- 11:12: ... wavefunction. This is analogous to how Lagrangian mechanics reproduced Newton’s mechanics. And it’s no coincidence, because the path integral is the quantum analog ...

2020-05-11: How Luminiferous Aether Led to Relativity
- 06:22: ... so we get to the end of the 19th Century. With Newton’s mechanics and gravity, Huygen’s optics, Maxwell’s electromagnetism, physics seemed ...
- 07:19: ... using the Galilean transformation, which is part of the foundation of Newton’s mechanics. I were a smug 19th century physicist, I’d wanna hope Galilean relativity ...

2018-02-14: What is Energy?
- 06:55: Just adding conservation of energy to Newton's mechanics gives an extra constraint that allows us to solve problems we couldn't otherwise.

2015-10-07: The Speed of Light is NOT About Light
- 02:11: By the late 1800s, we have Maxwell's equations, Newton's mechanics, various other awesome theories.
- 02:38: In fact, we now know that even Newton's mechanics were using assumptions that implied an infinite speed of light, which is really bad.
- 04:37: Newton's mechanics use it.
- 05:06: The transformation underpinning Newton's mechanics is wrong.
