 08:02: The first step was to reformulate MOND using Lagrangian mechanics.


20211102: Is ACTION The Most Fundamental Property in Physics?
 04:29: ... Least Action in combination with the EulerLagrange equations leads to Lagrangian mechanics. ...
 05:00: ... you study Newton’s mechanics and then move on to Lagrangian mechanics, it seems almost like a miracle. The hellishly complex equations needed ...
 07:09: ... Action holds up in GR  but it reveals a lot more. First, it means that Lagrangian mechanics based on this principle can be made to be “Lorentz invariant”  it gives ...
 11:12: ... about the evolution of a single wavefunction. This is analogous to how Lagrangian mechanics reproduced Newton’s mechanics. And it’s no coincidence, because the path ...


20190130: Perpetual Motion From Negative Mass?
 11:10: ... which itself arises directly from the equivalence principle, or from Lagrangian mechanics – a more modern version of Newton’s laws of ...


20180214: What is Energy?
 09:05: Actually, Lagrangian mechanics makes a quantum comeback here.
 09:19: Lagrangian mechanics is the inspiration behind Feynman's path integral approach to quantum mechanics.
