Development of the Wigner–Seitz method for interpreting metallic structure, study of Brillouin zones and calculations of energy bands in solids led to new understanding of molecular theory and of electronic structure in crystals.
MANY YOUNGER PHYSICISTS feel that all physics has grown up since World War II; or if they admit some earlier science, they feel that in this country everything started with the influx of European scientists as a result of political difficulties, beginning with the rise of Hitler in 1933, in Germany and Italy.
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.
