The physics of molecular films evolves from two dimensional to three dimensional as the films thicken, but remnants of two‐dimensional behavior persist in bulk materials.

Looking back half a century, a disciple of Wolfgang Pauli recalls how Pauli's extreme honesty and directness expedited work on fundamental problems in quantum mechanics and made for unusual human relations.

Local, state and national initiatives may have helped to improve precollege teaching and to make the career of science teacher more attractive, but a survey shows that much remains to be done.

With its power enhanced by synchrotron radiation, this technique for studying bulk and surface electronic structures goes to the heart of many problems in atomic, molecular and condensed‐matter physics.
