The week in physics: Pasta sauce rheology; Lessons from Stuart Freedman

The Week in Physics ADVERTISEMENT High-Resolution Laser Wavelength Meter Bristol’s 872 Series is ideal for the frequency stabilization of lasers, with 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 atomic cooling and trapping.

But his mentorship was an equally important contribution. Jill Marshall and Jim Napolitano APR 08, 2026 Quantum drops are spotted in ultracold gas of molecules Strong and tunable long-range dipolar interactions could help probe the behavior of supersolids and other quantum phases of matter. Alex Lopatka APR 06, 2026 ADVERTISEMENT Cryo-Hexapod for Quantum Applications PI’s compact cryogenic hexapod concept for ultraprecise alignment at temperatures close to absolute zero. Piezo-driven, low heat generation, non-magnetic & UHV-compatible. Enables stable positioning of optics and photonic devices in quantum, photonics, and physics experiments. Learn more. From the vault The electron dipole moment—A case history The anomalous magnetic moment of the electron is of great significance in the study of elementary particles and quantum electrodynamics. Its discovery is in large part the story of a technique, which was not invented for the specific purpose but which did, by permitting a discrepancy to appear where none was expected, answer an unasked question.
