    Physics Group Meeting
    “A Few Uses for Theoretical Physics in Machine Learning”

    Location: Bloomberg Lecture Hall
    Time: 1:45 PM
    Speaker(s): Dan Roberts, Member, School of Natural Sciences, IAS

  • Thursday, December 14, 2017
    Hamilton Colloquium Series
    “Exploring Embryonic Patterning with Colonies of Human Embryonic Stem Cells”

    Location: Jadwin Hall, Room A10
    Time: 4:00 PM
    Speaker(s): Eric Siggia, Rockefeller University

    Description: Embryology at the beginning of the 21st century finds itself in a situation similar to neurobiology; the behavior of the component pieces is understood in some detail, but how they self-assemble to become life is still very hazy. There are hundreds of  molecules that enable cell communication and genetics defines their function by classifying aberrant embryos at a suitable intermediate stage of development, which is difficult for mammals and impossible for humans. Embryonic stem cells can be expanded indefinitely and in the context of the embryo give rise to all cells in the body. The colloquium will describe synthetic systems that coax these stem cells to recapitulate aspects of gastrulation, which is the process by which the embryo transforms from a sphere to a cylinder, builds its anterior-posterior and dorsal-ventral axes, and segregates cells into ectoderm (skin and neurons), mesoderm (muscle bones and blood), and endoderm (gut, lungs, pancreas, etc.) lineages.

    Raymond and Beverly Sackler Lecture in Astrophysics
    “Fast Radio Bursts”

    Location: McDonnell A02
    Time: 8:00 PM
    Speaker(s): Victoria Kaspi, McGill University

    Description: In 2007, astronomers discovered a new mysterious cosmic phenomenon: Fast Radio Bursts. These events consist of short, intense blasts of radio waves arriving from far outside our Milky Way galaxy. Their origin is unknown, however Fast Radio Bursts appear ubiquitous in our Universe, with roughly 1000 arriving every day over the full sky. I will discuss the Fast Radio Burst mystery and what is presently known about it, and describe a revolutionary new radio telescope being built in Canada that will soon enable astronomers worldwide to make major progress in our understanding of the FRB puzzle.

    High Energy Theory Seminar
    “TBA”

    Location: Bloomberg Lecture Hall
    Time: 1:45 PM
    Speaker(s): Nima Lashkari, Massachusetts Institute of Technology

  • Monday, January 8, 2018
    PCTS Workshop
    “Gravity in the Early Universe”

    Location: Jadwin Hall, PCTS Seminar Room, Room 407
    Time: 8:30 AM
    Note: FREE, but REQUIRED REGISTRATION is limited and available online at http://pcts.princeton.edu/pcts

    Description: Program Organizers: Anna Ijjas (Columbia), Frans Pretorius (Princeton), Paul J. Steinhardt (Princeton-PCTS)

    This workshop will focus on modifications of Einstein gravity at high (but sub-Planckian) energy densities that would influence the dynamics and evolutionary history of the early universe. Of particular interest are a variety of recent proposals for avoiding the cosmological singularity by stably violating the null energy condition while remaining in the regime of validity of classical field theories. Understanding these approaches requires the development of new ideas, new analytical tools, and new numerical techniques. The goal is to bring together leading experts in cosmology and general relativity to explore these ideas.

    We will have only five speakers and each will be given two 1.5 hour slots, so that there is time for a more pedagogical presentation and lots of time for questions and interaction during and after.
