I did search for topics in this forum. but i could not find basics that deal with hamiltonian of the system(adsbygoogle = window.adsbygoogle || []).push({});

Well I'm pretty new to the field of quantum mechanics. I just could not understand what exactly it means by the hamiltonian of a system? I was told that it describes the total energy of the system. If that is the case how does it describes the total energy? and does this total energy includes the energy for the interaction with the surroundings.

Can you please provide a small lay man example and explain the same
