The week in physics: Back to the March Meeting; Torsion balances; Fabric microphones

Physicists happy to be back face-to-(masked)-face at APS March Meeting Forward this email  View in your browser THE WEEK IN PHYSICS: 21–25 MARCH Advertisement DIY vs Professionally Built, Calibrated XYZ Systems Which is the better solution? DIY can save money but could sacrifice performance and precision. If the ultimate performance and up-time are critical, take a look at a custom aligned, tuned, and error corrected integrated XYZ motion system. Learn more. Of torsion balances and construction cranes A new technique to damp the motion of a torsion pendulum, which is used to measure the gravitational constant, is already familiar to operators of tower cranes. Andrew Grant Physicists happy to be back face-to-(masked)-face at APS March Meeting The meeting recaptures much of the pre-pandemic experience, but the hybrid format still has some issues to iron out. Christine Middleton and Heather M. Hill April magazine preview Ballooning satellite populations in low Earth orbit portend changes for science and society Technological advances and business incentives far outpace space regulations. Toni Feder FROM THE VAULT: October 2002 Toward a synthesis of the Newtonian and Darwinian worldviews Physicists seek simplicity in universal laws. Ecologists revel in complex interdependencies. A sustainable future for our planet will probably require a look at life from both sides. John Harte Advertisement RGA and Process Gas Monitor – PrismaPro® The Pfeiffer Vacuum PrismaPro quadrupole mass spectrometer is designed for both qualitative and quantitative gas analysis, as well as RGA and leak detection. The PrismaPro is built rugged and features a distinctive combination of high sensitivity with a detection limit of <3E-15 mbar, maximum stability, and intelligent operation. Learn more. Fabric microphone picks up acoustic vibrations When woven into clothing, the novel fiber can monitor a wearer's heart rate and be used for other health and communications applications. Alex Lopatka Coulomb-explosion imaging tackles an 11-atom molecule Until now, the technique was thought to work only on molecules with approximately five or fewer atoms. A powerful x-ray source leaves that limit in the dust. Johanna L. Miller Advertisement Peering inside carbon nanotubes When Vikram Desphande wanted to study the behavior of electrons coursing through carbon nanotubes, he turned to ICEoxford's DRY ICE 1.5K 70 mm cryostat. See how the cryostat is allowing the University of Utah physicist to conduct innovative measurements of delicate quantum effects. Read now. FROM THE MARCH MAGAZINE Philip Anderson: Virtuoso of condensed matter The theorist's work on disordered and magnetic solids earned him a Nobel Prize, but it was his profound influence on the condensed-matter community—and well beyond—that set him apart.
