Gauge invariance applies to statistical mechanics too Forward this email View in your browser The week in physics: 6–10 January Advertisement 872 Series High-Resolution Laser Wavelength Meter Bristol's 872 Series is ideal for the frequency stabilization of lasers. This system offers a frequency resolution as high as 200 kHz, resulting in exceptional sensitivity to wavelength deviations. With a built-in PID controller and 1 kHz sustained measurement rate, the 872 system is well-suited for applications such as atomic cooling and trapping.

Johanna L. Miller Helping physics departments thrive Capturing the wisdom of hundreds of individuals and departments, the Effective Practices for Physics Programs guide is a handbook for creating significant and sustainable change. David Craig, Theodore Hodapp, and Michael Jackson From the vault: December 2018 On science in a small country Wales tends to fall by the wayside in narratives about the history of science, but its stories complicate and enrich our picture of science's past and future. Iwan Rhys Morus The lessons learned from ephemeral nuclei Recent experimental analyses of fleeting clusters of protons and neutrons put the very notion of the atomic nucleus in a new light. Witold Nazarewicz and Lee G. Sobotka From the January magazine Stories from the early days of quantum mechanics A colloquium delivered to the University of Toronto physics department on 5 April 1979 by the master of molecular beams offers a fresh look at an earlier era.
