New Measurements Standards for 1990
Physics Today 42 (8), 23–26 (1989);
https://doi.org/10.1063/1.881176
On New Year's Day, new practical reference standards for the volt and the ohm will take effect worldwide. Both will be based on highly reproducible quantum effects rather than artifacts. The practical temperature scale will also change.
Reaching the Critical Mass in High School Physics
Physics Today 42 (8), 30–36 (1989);
https://doi.org/10.1063/1.881177
The picture that emerges from the inaugural AIP‐AAPT survey of high school physics teachers is of a program that touches few students—and a select few at that in terms of gender, race, social class and geographic region.
The First Texas Symposium on Relativistic Astrophysics
Physics Today 42 (8), 46–52 (1989);
https://doi.org/10.1063/1.881214
Born at poolside on a summer afternoon, the idea for a Texas‐sized conference blossomed when it was realized that the newly found quasars might be relativistically significant.
