- We’re remembering physicist Henry Moseley, who uncovered a precise mathematical relationship between an element’s X-ray spectrum and its atomic number.. Learn more about Moseley’s contributions to #PhysicsHistory in APS News: go.aps.org/39g4VGm.
- Our refreshed data availability policy means that all articles in the Physical Review journals will have a statement detailing where data can be accessed. It goes into effect for @PhysRevD and @PRX_Energy on Sept. 4 and our other journals by year end. 🔗 go.aps.org/3WMXq40
- Have you seen today’s #GoogleDoodle? The illustration celebrates mathematician Olga Ladyzhenskaya's 97th birthday. Her work in fluid dynamics led to the development of equations used in meteorology, aeronautics, medicine, and more. go.aps.org/2C8ixEn #WomensHistoryMonth
- It's official! The kilogram is no longer defined by a piece of metal in Paris. The kg and other SI units are now rooted in precise quantum constants, pushing our precision to new heights . go.aps.org/2w97S8K via @voxdotcom #WorldMetrologyDay
- #OTD in 1595, astronomer Johannes Kepler had an epiphany: There might be a geometric underpinning to the universe. Learn more about the idea that helped Kepler bridge the gap between #physics and #astronomy in #APSNews: go.aps.org/3fDpNtD. #PhysicsHistory
- Due to rapidly escalating health concerns relating to the spread of the coronavirus disease (COVID-19), the 2020 APS March Meeting in Denver, CO, has been canceled. Please do not travel to Denver to attend the March Meeting. More information will follow shortly. #apsmarch
- In August 1774, chemist Joseph Priestley ran an experiment that revealed that air is a mix of gasses — a finding that eventually led to the discovery of oxygen. Read more about Priestley’s research and legacy in APS News: go.aps.org/4dhHZGy. #PhysicsHistory
GIF - On #InternationalCatDay, we're tipping our hats to F. D. C. Willard, the only feline coauthor in physics history! In 1975, Willard — AKA Chester — was listed as an author on a #physics paper in @PhysRevLett: go.aps.org/3ONv9Gv. 📷 Google Scholar
- Lawrence Bragg was a @Proud_Sappers engineer, director of @Ri_Science—and the youngest @NobelPrize in #Physics laureate at age 25. See how his riverside stroll inspired the field of x-ray crystallography in #PhysicsHistory: go.aps.org/2xGoO7D.
- In August 1932, Carl Anderson discovered the #positron, the antiparticle of the electron, which earned him the @NobelPrize in #Physics in 1936. Learn more about Anderson and this moment in #PhysicsHistory: go.aps.org/3LZltXs.
- Joan Feynman, an astrophysicist known for her discovery of the origin of auroras, died on July 21. She was 93. go.aps.org/3gTkzKX
