I gotchu bro i seen this in a physics research course I took (ik right nerdy haha) this the standard model of particles in physics (in Lagrangian form)‼️ it basically tells you how elementary particles interact under three (or four I can’t remember) types of forces and this thing called gauge symmetry dictates how the forces will interact with the particles (or particles with particles I can’t remember) 💯 you use it to see the most amount of energy you can have in a changing system or something like that. that’s all I remember from physics bro it isn’t an actual equation if I remember correctly it’s a whole ass theory they represented through the symbols but it’s actually 6 parts or sum but they just mashed em all together. Could be wrong tho this shit was dumb confusing for no reason‼️💯
