  • Dr. David Morrison, Duke University, Decay of False Vacua
    cosmology where it is related to inflation and in string theory where it is related to supersymmetry breaking We study some models introduced by Adams Polchinski and Silverstein for the decay of false vacua in string compactifications Getting a handle on both the evolution of spacetime and the end product of the decay involves some sophisticated tools from a branch of mathematics algebraic geometry in all but the simplest cases

  • Dr. Ed van den Heuvel, Universiteit van Amsterdam, Historical Notes on the Dutch and American-Dutch "schools" in Astronomy and Their Relations with Physics
    Kapteijn and his pupils De Sitter van Rhijn Oort and Schilt Kapteijn through his friendship with George Ellery Hale initiated the strong connection between American and Dutch astronomy which led to the rise of many Dutch born astronomers to prominent positions in the US from Luyten Bok Brouwer Schilt and Kuiper to Woltjer Gehrels and Beckers The rise of the second golden age appears to be closely related to drastic

  • Dr. Rajnish Mehra, UCSB & National Bureau of Economic Research, The Equity Premium: Why is it a Puzzle?
    allocation capital budgeting and planning for retirement Historical data provide a wealth of evidence documenting that over long periods of time stock returns have been considerably higher than the returns for T bills The average annual real return that is the inflation adjusted return on the U S stock market for the past 115 years has been about 7 5 percent In the same period the real return on a relatively riskless security was a paltry 1 0 percent The difference between these two returns 6 5 percentage points is the equity premium The dramatic investment implications of these differential rates of return is illustrated below Ending Value of 1 Invested net of inflation Investment Period Stocks T Bills Ratio 1889 2004 4092 36 3 14 1 303 30 1926 2004 407 56 1 67 244 05 1947 2004 61 70 1 33 46 39 In this talk which is based on my joint work with Ed Prescott I discuss what constitutes risk and why the fact that stocks have been such an attractive investment relative to bonds presents a fundamental challenge to the standard model in Finance and Economics Begin streaming QuickTime of the whole talk high bandwidth Or

  • Dr. Bill Rice, UCSB, Reproductive Interactions Between the Sexes: Sexual Conflict or Mutualistic Sexual Selection?
    synthetic female resistance genes to tease apart the costs and benefits of male female interactions from the female s perspective These experiments were done to evaluate whether or not many of the apparent harmful effects of males on their mates are compensated by genetic benefits associated with increased quality offspring Lastly I describe my lab s use of genome wide cytogenetic cloning to measure ongoing antagonistic coevolution between the sexes

  • Dr. Andrew Hamilton, University Colorado, Inside Black Holes
    case of the Schwarzschild solution the vacuum solutions for the interiors of black holes are inconsistent as endpoints of gravitational collapse because the cores of vacuum black holes are gravitationally repulsive Instead black holes must contain matter As first pointed out by Poisson and Israel 1990 the key physical effect that changes the interior structure of a black hole from the vacuum solution is mass inflation near the inner horizon Mass inflation seriously modifies the geometry of a black hole inside the region where the inner horizon would be in a vacuum black hole Mass inflation is driven by a feedback effect in which counter streaming between ingoing and outgoing fluids generates a large pressure which generates a large gravitational force which accelerates the ingoing and outgoing fluids ever faster through each other I argue that a generic result of the mass inflation instability is to produce a relativistic plasma inward of the erstwhile inner horizon If you fall into a supermassive black hole where the tidal forces are relatively weak chances are you will die by being vaporized by the relativistic plasma before you are torn apart by tides Begin streaming QuickTime of the whole talk high bandwidth Or
