Certain [[system]]s, however, do exhibit quantum mechanical effects on a larger scale; ''superfluidity'' (the frictionless flow of a liquid at temperatures near absolute zero) is one well-known example. Quantum theory also provides accurate descriptions for many previously unexplained [[phenomena]] such as black body radiation and the stability of electron orbitals. It has also given [[insight]] into the workings of many different [[biological]] systems, including smell receptors and protein structures.[3]

Even so, classical physics often can be a good approximation to results otherwise obtained by quantum physics, typically in circumstances with large numbers of particles or large quantum numbers. (However, some open questions remain in the field of [http://en.wikipedia.org/wiki/Quantum_chaos quantum chaos].)
