Physicists make breakthrough in understanding turbulent fluids
Over the course of three days, the festival featured the work of over fifty contributors. It was attended by nearly a hundred people each day. During each of the festival’s four themed sessions, videos, conversation, and live performances took place in rapid succession. In the dialogue that emerged, the boundaries between disciplines blurred, as scientists danced their research, played their data as sound, and discussed favorite pieces of art, challenging their colleagues to do the same—sometimes in real time. Artists, on the other hand, explained particle physics models through textiles, magnetism through dance, and physics fundamentals through comic books.
Multimessenger observations of neutron stars have been used by astrophysicists in the US to put Einstein’s general theory of relativity to the test – and the 106 year old theory has passed with flying colours.
In a paper published today in Physical Review Letters, a team of researchers led by Illinois Physics Professor Nicolás Yunes present two conclusions. First, using NICER’s observation datamand universal relations among various properties of neutron stars, the authors infer the moment of inertia; the tidal Love number; the quadrupole moment; and the surface eccentricity of neutron star PSR J0030+045. Next, they use their inferences to propose and implement a novel test of GR.
Illinois Physics Professor Smitha Vishveshwara has been elected to the Executive Committee of the American Physical Society (APS) Division of Condensed Matter Physics (DCMP). By special election, Vishveshwara fills the seat of Richard L. Greene of University of Maryland, who stepped down from the position of chair-elect.
The DCMP chair line typically represents a four-year commitment of service, and each newly elected member generally starts as vice chair for the first year, then serves as chair-elect, chair, and past chair. Vishveshwara will serve as chair-elect starting immediately, and will take over as chair in March 2022.
