Past Events

  • Special seminar on the recent Event Horizon Telescope results: "The Black Hole Shadow in M87"

    David Rittenhouse Laboratory, A6

    Dan Marrone, University of Arizona

    The Event Horizon Telescope (EHT) is an international collaboration to observe black holes at horizon-scale resolution. The EHT uses the technique of very long baseline interferometry (VLBI) and submillimeter telescopes all over the globe to perform VLBI experiments at 1mm wavelength, where we expect to resolve the event horizons of two targets, M87* and SgrA*. In 2017, the EHT performed its first experiment, using eight observatories at six geographic locations.

  • SPECIAL MEAM/MSE SEMINAR: "Scalable functional phase change materials for displays and photonic non-von Neumann computing"

    LRSM Reading Room

    Harish Bhaskaran, University of Oxford, UK; Co-founder of Bodle Technologies

    Talk Abstract:  In electronics, doping silicon results in one of the most versatile functional materials ever employed. The pursuit of such functional materials in the optical domain is an area of great interest in the photonics community. I hope to convince you that whatever route photonics takes, a class of materials known as phase change materials, will play a key role in its commercialization.

  • Women in Physics Public Lecture: "The Most Magnificent Map Ever Made"

    Ben Franklin Room, Houston Hall

    Beth Willman, University of Arizona

    For all of history, humans have observed the Milky Way galaxy by eye as a structure encircling our night sky. However, only within the last 100 years have humans learned that the Milky Way is not the only galaxy in the Universe. Within the last two decades, we have learned that the Sun is one of hundreds of billions of stars in the Milky Way, that the Milky Way is one of hundreds of billions of galaxies in the Universe, and that galaxies exist that are only one ten millionth as luminous as the Milky Way.

  • Special Seminar: "This Is Not A Diversity Talk"

    David Rittenhouse Laboratory, A8

    John Asher Johnson, Harvard University

    The American discourse on the various disparities present in society generally, and academia specifically, focuses primarily on observations of the state of a given situation---e.g. a lack of diversity---rather than on the actions that lead to such a state. This approach is just as dissatisfying and ultimately ineffectual as observing that certain stars are "bright," rather than describing any of the physical principles that lead to the observed properties of a star.

  • Security and Donuts (and 2-Step enrollment)

    Physics Faculty Lounge

    Nick Salvatore, Chris Lake, and Shaheen Beg

    In observance of National CyberSecurity Awareness Month, Nick Salvatore, Chris Lake, and Shaheen Beg will be hosting an Information Security Outreach day next week. If you need help with setting up 2-Step Authentication, have questions about how secure your research data is, or if you just like donuts, stop by our event!

  • Special Soft Matter Seminar: "Physical interactions reduce the power of natural selection in growing yeast colonies"

    David Rittenhouse Laboratory, 3C2

    Andrea Giometto, Harvard University

    Microbial populations often assemble in dense populations in which proliferating individuals exert mechanical forces on the nearby cells.

  • Public Event on the evening of June 19 including programming in DRL and night sky observing on Shoemaker Green

    David Rittenhouse Laboratory, 209 S. 33rd Street

    The panel discussion will be moderated by Dr. Derrick Pitts, Chief Astronomer at the Franklin Institute

    • How do I become an astronomer?
    • What’s it like to be an astronomer?
    • How do astronomers study the early universe?

    The panel discussion will be moderated by Dr. Derrick Pitts, Chief Astronomer at the Franklin Institute, and will feature three Simons Observatory scientists who recently authored fascinating tales of our universe and their journeys to understand it!

  • Elon Musk Public Lecture: "Will Evolution and Information Theory Provide the Fundamentals of Physics?"

    Meyerson Hall, B1 (210 S. 34th Street)

    Sylvester James Gates, Jr. (Brown)

    Join us for an evening with theoretical physicist Sylvester James Gates, Jr., as he talks about how the mathematical and theoretical aspects of his physics research have traversed concept spaces from equations to graphical imagery to coding theory error-correction, and how it points towards evidence that an evolution-like process may have acted on the mathematical laws that describe reality.

  • Math/Phys Joint Seminar: "Progress Toward A Mathematically Rigorous Space-time SUSY Representation Theory"

    David Rittenhouse Laboratory, 4C2

    Sylvester James Gates, Jr. (Brown University)

    While a fundamental representation theory for compact Lie algebras was settled by the work of Cartan (i.e. weights and roots), no analogous conceptual structure exists for space-time supersymmetry algebras.  Progress in this direction based on the graph theory concept of "adinkras" will be presented in this talk.


    David Rittenhouse Laboratory, Room A8

    Procotor will be on site
