Absolute zero: the coldest anything can ever get. To reach this temperature, all motion in the system must completely stop, something which is impossible according to quantum mechanics. So, if we can never hope to even reach absolute zero, it would seem that it is ridiculous to even consider temperatures below that. However, if we generalize our definition of what we mean by temperature to include systems where the traditional definition fails, we find that it is not only possible to reach negative absolute temperatures, but in fact, it is relatively simple to do.
