  • Mehran Kardar, MIT & KITP, The Elusiveness of Polymer Knots
    biological Somewhat contrary to intuition physical considerations energy or entropy are found to favor tight knots with the entanglements localized on relatively small segments Knots are also statistically rare in swollen coil polymers but abundant in compact globular configurations Yet our investigation of the Protein Data Bank reveals very few knotted structures in globular proteins I shall discuss some intriguing examples of this set including the most complicated protein knot

  • Robert Socolow, Princeton Univ., Technologies for Living in a Greenhouse
    wedge is focused on a specific source of emissions means of mitigation or technologies to reduce demand That model provides access points to first stabilizing and then reducing greenhouse gas emissions applicable both globally and by the individual Socolow and Pacala are widely regarded as major innovative thinkers and key strategists in addressing climate change Begin streaming QuickTime of the whole talk high bandwidth Or right click to download the

  • John Learned, Univ. of Hawaii, Hanohano: Mobile Neutrino Detectors for Mixing, Masses, Geology, and Reactor Snooping
    both peculiarly small but finite neutrino mass and the strange business of neutrinos morphing from one type to another The art has advanced to the state of starting neutrino applications and many new initiatives are underway or proposed Using neutrinos as unique geological probes will grow into a new field of geoneutrino measurements to understand the earth s dynamics and composition There remains much particle physics to be done too

  • Eva Silverstein, Stanford University, Inflationary Theory, String Theory and the CMB
    input from an ultraviolet complete theory of gravity such as string theory I will describe two particular observables of interest a gravity wave signature from inflation and non Gaussian corrections to the power spectrum Building on our progress stabilizing string compactifications in recent years I will describe two basic mechanisms for inflation each of which yields one of these distinctive signatures Falsifiable on the basis of current and near term

  • Reinhard Genzel, Max Planck & UC Berkeley, The Nuclear Star Cluster and Central Massive Black Hole
    Galactic Center thus constitutes the best astrophysical evidence for the existence of black holes which have long been postulated and is also an ideal lab for studying the physics in the vicinity of such an object Remarkably young massive stars are present there and probably have formed in the innermost stellar cusp Variable infrared and X ray emission from SgrA are a new probe of the physics and space time

  • Karin Dahmen, UIUC, Crackling Noise: Learning from Magnets about Earthquakes?
    on modeling the statistics of earthquakes in irregularly shaped fault zones and motivate new ways to analyze seismic data In particular we focus on the universal i e detail independent effects of disorder in both cases The studies draw on methods from the theory of phase transitions Applications to other crackling systems are also discussed Begin streaming QuickTime of the whole talk high bandwidth Or right click to download the
