So after reading a bit particle physics, the lagrangian is defined as the difference between kinetic and potential energy: L = EK-EP. It is supposed to be conserved in particle interactions. However i dont know why it is conserved, so can anyone please explain to me why?(adsbygoogle = window.adsbygoogle || []).push({});

Thanks a lot :)
