The week in physics: Planning reactions to the Oppenheimer investigation

The Week in Physics Planning reactions to the Oppenheimer security-clearance review Cognizant of their role within the scientific community, scientific societies had to weigh how to respond to the actions by the Atomic Energy Commission. Allison Buser MAY 14, 2026 From the archives The Princeton period This article, on J. Robert Oppenheimerʼs tenure as director of the Institute for Advanced Study, appeared in a special issue on Oppenheimer that was published shortly after his death. Abraham Pais MAY 14, 2026 ADVERTISEMENT Ultrafast fiber laser: 30 fs now with 3 W HÜBNER Photonics announces a higher power model of the VALO Tidal femtosecond laser. Now available with 3 W, the VALO Tidal delivers pulse durations of typically 30 fs in a compact and robust footprint, making it perfect for multiphoton imaging, broadband terahertz generation, and nonlinear wafer inspection. From the vault Gravitational theory and observation Fifty years after Einstein formulated general relativity, an expermentalist looks at the observational support for this theory. He finds that the evidence is at least as good for a scalar‐tensor theory of gravitation. Robert H. Dicke JAN 01, 1967 Q&A: Amal Kasry works to strengthen science where it’s most needed For the UNESCO section chief, “striking a balance between global coherence and respect for national ownership and cultural diversity is both essential and complex.” Toni Feder MAY 13, 2026 FYI science policy news Trump fires National Science Board; White House seeks to stop paying publishing fees Jacob Taylor and Lindsay McKenzie MAY 13, 2026 ADVERTISEMENT J. Robert Oppenheimer—In His Own Words For the first time, three rare oral history interviews are publicly available, offering insight into one of the most influential figures in modern science.
