Issues

Accelerators that will produce 500–1000 MeV nucleons and mesons in beams thousands of times more intense than existing machines will be able to do experiments never before possible, increase precision of others and reveal processes now unknown

After more than a century of experimental study, an explanation of the electrical properties of liquid metals is now available. Concepts such as “nearly free electrons,” “pseudopotentials” and “pseudo‐atoms” have helped to solve the problem. But an exact description of what happens when the orderly solid crystal melts into the disordered liquid remains a challenge.

Historical and personal circumstances blocked the career of this right‐wing, royalist, religious extremist despite a variety of important contributions. His work is now gaining greater recognition.
