Thermodynamics of critical points
Physics Today 21 (2), 23–28 (1968);
https://doi.org/10.1063/1.3034760
There is in general no accurate theoretical description of the behavior of a system as it passes through its critical point. Current work, both experimental and theoretical, attempts to provide a unified theory that will be applicable to many different kinds of phase transition.
Sonic booms
Physics Today 21 (2), 31–37 (1968);
https://doi.org/10.1063/1.3034761
How are sonic booms created? What do they do to people and buildings? Will the future be dominated by the boom?
Electroluminescence
Physics Today 21 (2), 43–48 (1968);
https://doi.org/10.1063/1.3034762
Improved understanding of electron‐hole recombination in semiconductors has accompanied efforts to increase the efficiency of diodes that emit visible light.
