THE BEST VIDEO ABOUT LAGRANGIAN MECHANICS IM ACTUALLY CRYING<br>Edit: Can you make a separate video about Hamiltonian mechanics?

FINALLY someone who actually explained where the lagrangian came from!!!! Thank you!!!

I had been waiting for that video for almost 30 years ... First time ever I see an explanation for why the Lagrangian is T-V. Awesome work, thank you! The only obscure part left as far as I am concerned is the one justifying that the time variation of the mean value of L should be 0, and how it relates to determinism ...

This is the most elegant description of Lagrangian mechanics I have yet seen. Mind blowing stuff.

Never saw such a good explenation of Lagrangian Mechanics. Wish that my professors would have just a tenth of your teaching skills.

OMG! U re the only person on Youtube that actually understands Langrangian mechanics! please make a video about Hamiltonian mechanics too!

This is the ONLY explanation I've seen on YouTube. I dont understand why others, including physics luminaries, just dump the formula on the screen and then explain algebra. This is BRILLIANT!

Excellent demonstration of the thought behind how Lagrangian is created. Thanks so much! This is particularly useful for people who wants to pursue a more rigorous mathematical thinking behind Physics.

Flipping the potential energy axis in the 3D-view tied a knot in my brain.

I look forward to seeing a mathematical connection between spacetime geometry and the quantum mechanics states for momentum and position. Something that is natural and common sense.

This is a masterpiece. It would be nice to compare and contrast with Hamiltonian mechanics which uses the sum of kinetic and potential energies.
