RIght, everytime I hear someone define absolute zero lately they say that it is when all of the atoms are in their lowest energy states, which leaves a finite amount of energy because the uncertainty principle does not allow knowing exactly where something is and how fast it is moving, and if there is absolutely no energy (above mass-energy and such) you know the speed exactly and where it is. So, what amount of energy is there left? Is it a range of energys? If so how big is it? And does the energy that you can say is left depend on just how well you know where the atoms all are?
