To avoid anomalies of spin and statistics Pauli suggested in 1930 that a neutral particle of small mass might accompany the electron in nuclear beta decay, calling it (until Chadwick's discovery) the neutron.

A large optical and infrared instrument of novel design nearing completion on Mt Hopkins is the first example of a class that could include telescopes much larger than any now existing.

Physicists have made great progress both on fundamental problems, such as turbulence and statistical mechanics, and on many applications, including aerodynamics and the study of geophysical flows.
