    In 1827, Robert Brown discovered Brownian motion by observing pollen in water. This pivotal observation later influenced Albert Einstein's 1905 work on molecular theory. Learn more: go.aps.org/3LQiQXD. #PhysicsHistory
    Black and white illustration of Robert Brown, depicted in formal attire with a high-collared coat and a cravat. His hair is styled in waves, and he has sideburns. His expression is serene, facing slightly towards the viewer's left.

    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
    The new kilogram just debuted. It’s a massive achievement.

    #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
    This is a detailed black-and-white line drawing depicting Kepler's Platonic solid model of the solar system. It is an intricate geometric sculpture featuring nested shapes, primarily triangles and squares, inside a spherical framework. The base of the sculpture includes mechanical components suggesting movement or adjustability. The design combines aspects of architectural drafting and optical illusions, emphasizing a complex three-dimensional perspective.

    Meme of two photos from the Olympics. On the left is shooter dressed in black with a backwards cap and special glasses. Their right arm is aiming a pistol toward a target. The shooter on the right has short salt and pepper hair, black-framed glasses. Their right arm aiming a pistol toward a target while their other hand is in their pocket. White text on the left reads "Everyone else who read the paper." White text on the right reads "Reviewer 2."

    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

    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
    Close-up of a Siamese cat with it's eyes closed, seated and facing the camera. Its fur is primarily cream-colored with darker fur on the ears, face, paws, and tail. The background features a softly blurred indoor setting.

    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.
    Black and white portrait of Lawrence Bragg, looking directly at the camera with a serious expression, wearing a suit with a patterned tie.

    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.
    A 63 million volt positron passes through a 6 mm lead plate and emerges as a 23 million volt positron. The length of this latter path is at least ten times greater than the possible length of a proton path of this curvature.
