Lagrangian mechanics is the most beautiful thing I've ever seen
I was scrolling through the wiki page for simple pendulum motion and I noticed the Lagrangian derivations. Up to this point I'd only known the derivations from forces or energy from Newtonian mechanics, and the idea that you could get so much from L=T-U made me super fascinated. So I started watching some lectures and practicing problems, and it's been so fun that I might even take the full course when the summer break is over. #science
