This Week in Physics - Satellite Confirms the Principle of Falling

This Week in Physics Magazine — September 19, 2022 Viewpoint Satellite Confirms the Principle of Falling Philippe Brax – September 14, 2022 The MICROSCOPE satellite experiment has tested the equivalence principle with an unprecedented level of precision. Special Feature The Equivalence Principle under a MICROSCOPE September 14, 2022 A cartoon illustrates results from the MICROSCOPE satellite mission, which has measured with astronomical sensitivity the falling rate of different objects under gravity. Research News Laser-Accident-Turned-Surgery-Breakthrough Wins Golden Goose September 14, 2022 A team of physicists and clinicians will today be honored for their development of the bladeless eye surgery technique known as LASIK, an advance partly aided by a lab mishap involving an eye and a laser. Viewpoint A Solid Observation of Strong Kerr Nonlinearity Mitsuyoshi Takahata and Nobuko Naka – September 19, 2022 Researchers have demonstrated that a solid can exhibit an enhanced nonlinear optical phenomenon usually seen only in cold atomic gases. synopsis Strobing Light Shapes Atomic Array September 14, 2022 An optical tweezer with a stroboscopic twist can trap cold atoms in lattices of all shapes. synopsis Mini Interferometers Offer Impressive Sensitivity September 15, 2022 A sensor containing thumbnail-sized interferometers might help astronomers detect gravitational waves emitted from certain black hole mergers. Q&A Interaction Detection with Attosecond Perfection September 16, 2022 Mina Bionta explores how light interacts with matter by capturing snapshots of those interactions on the timescale of the light's oscillations. synopsis Modeling Landslide-Induced Tsunamis September 13, 2022 A new model can accurately predict the height of waves created when a cliff collapses into water, allowing for a better evaluation of the threat the incident may pose to local people. synopsis A Jiggling Ultracold Atomic Gas Simulates Spin Dynamics September 19, 2022 Researchers produce analogues of hard-to-study quantum phenomena in a gas of strontium atoms near absolute zero. 1 Physics Ellipse, College Park, MD 20740 © 2022 American Physical Society | All rights reserved View Email Online You are receiving this message because you signed up to receive Physics Magazine email alerts or are a member of APS.
