dear sir, we know that third law of motion says that every action has a equal and opposite reaction. quantum mechanics tells us that it is possible not predict the position as well as the speed of electron. i like to know if electrons ,protons and neutrons form a system called atom. each of the components interact with each other and we also know where the protons and neutron are in nucleus and their speed. my question is if i am correct why can not we have a equation for path of electron?
