What Is Life? information has to be both small in size and permanent in time, contradicting the naïve physicist's expectation. This contradiction cannot be resolved by classical physics. In chapter IV, Schrödinger presents molecules, which are indeed stable even if they consist of only a few atoms, as the solution. Even though molecules were known before, their stability could not be explained by classical physics, but is due to the discrete nature of quantum mechanics. Furthermore, mutations are directly linked to quantum leaps. He continues to explain, in chapter V, that true solids, which are also permanent, are crystals. The stability of molecules
Institute for Theoretical Atomic, Molecular and Optical Physics who was later joined as joint director by Misha Lukin. In 2016 the director is Hossein Sadeghpour. Institute for Theoretical Atomic, Molecular and Optical Physics The Institute for Theoretical Atomic, Molecular and Optical Physics (ITAMP) is an international scientific learned society based at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. It was established in 1988 to alleviate a perceived shortage of theorists in atomic, molecular, and optical physics (AMO) at major universities throughout America. AMO concerns the study of matter-matter and light-matter interactions at the scale of one or a few atoms. The stated objectives of the Institute are:
