The Most Fundamental Principle in Classical Mechanics

The most basic thing about legrangians that we've explained is basically, i just a difference in energy. And the legrangian is doing the same thing that newtonian mechanics does. It's basically, its goal is just to explain the that the system evolves. We hold on. Can you just explain the legrangia and then do the principle of least action next time? Ecase i can explain the quanta mechanical reason why the Principle of least action works. O. Ot a ti ao, very gras a caotic, but still be an introduction to explaining what it kind of means to be chaotic. Because that's like, it hat's kind of what it
