Our motive is to deal with perturbation more efficiently; along the way we touch topics like the problem of approximating unsolvable differential equation in physics and renormalization.36en-USFeynmanperturbationrenormalizationclassical mechanicsperturbációrenormalizációklasszikus mechanikaFeynman diagrams in classical mechanicsFeynman diagramok a klasszikus mechanikábanDEENK Témalista::FizikaDEENK Témalista::Fizika::Elméleti fizika
