Acoustics flourishes, despite the tendency of outsiders to regard “true” acoustics as minute and relatively unimportant, with any significant work considered part of some other discipline.
In late 1969, the National Academy of Sciences created a committee, chaired by D. Allan Bromley of Yale University, to survey the state of physics. In due course, Bromley organized a set of panels, dividing physics into such recognizable areas as nuclear physics, elementary particles, condensed matter and the like. The first part of the report of this committee has now appeared, and more will follow.

With strong magnetic fields and intense lasers or pulsed electric currents, physicists can reconstruct the conditions inside astrophysical objects and create nuclear-fusion reactors.
A crude device for quantification shows how diverse aspects of distantly related organisms reflect the interplay of the same underlying physical factors.
