It is scheduled for launch in 2012. LISA will detect gravitational waves in the frequency range of 0.1 mHz to 100 mHz with a strain sensitivity integrated over a year of up to 10-23 m/m and directional resolution of better than one degree. We discuss the detectable sources of gravitational radiation and the configuration of the experiment. A technology demonstration for LISA is scheduled for flight in 2007.

Dept., SFSU Monday March 1, 2004 Topic: Neutrino Masses Abstract: In recent years the experimental evidences that the neutrinos have tiny masses are mounting. We review the data and describe the theoretical motivations for small neutrino masses. In particular, we show how neutrinos probe the physics at very small distances..

Peterfreund Associates, Amherst, MA Monday March 8, 2004 Topic: Have Exotic Baryon Resonances Been Discovered? Abstract: The numerous established baryon states (excited states of protons and neutrons) are well understood as combinations of three valence quarks. Do there exist in nature baryon states that require more complex structures such as four quarks plus an antiquark? Before 2003 there was no evidence for such states, but, in the last year, several groups have claimed significant observations of resonant structure that, if correct, can only be interpreted as one or more exotic states. I shall briefly describe the new results, discuss how they may (or may not) relate to the wealth of older data, and indicate what further measurements may be desirable to compellingly establish that indeed an important new discovery has been made.

LA Monday March 29, 2004 Topic: "The Hunt for Habitable Planets" and the Kepler mission Abstract: It wasn't long ago that the roster of Solar System planets was filled - with Neptune (1846) and Pluto (1930) completing the list. Yet today more than 100 other planets are known to orbit the nearest stars. Growing at a rapid pace, this list of extra-solar planets is yielding important statistics on the characteristics of giant planets. And the not-so-distant future promises to bring similar statistics about the more elusive Earth-like planets as NASA continues to put its cutting-edge technology into space. The Kepler project is a NASA Discovery mission whose objective is to identify Earth-like planets orbiting sun-like stars. I will give an overview of the Kepler science objectives and discuss the progress of the mission over the last year - its first since selection. Speaker: Dr. Natalie Batalha, San Jose State

Gaskets Abstract: Sometimes the terms "fractal"
and "Julia set" are used in a undistinguished manner to describe
certain sets that arise from iterative methods in dynamical systems
or topology. This is not always correct. Consider
the Sierpinski gasket, which is a classical example of a fractal set
(broadly speaking, is a self-similar set with a fractal dimension).
Many are the methods to produce such set, some of them are topological
in nature (as the iterative process of removing open middle equilateral
triangles) and some are more dynamical (e.g. the "chaos game").
On the other hand, the Julia set of a map can
be defined to be the closure of the set of points that under iteration
exhibit an unpredictable behavior. For example, the Julia set of the
map z\to z^2 is no other than the unit circle, since all other points
either map toward infinity or toward the zero under iteration of the
quadratic map. Clearly, the circle is a set of dimension one. Then, not all Julia sets are fractals and not
all fractals arise as Julia sets of some map. Well, not quite. In this
talk we present two families of rational maps of degree three and four
acting on the Riemann sphere. We will show that the Julia sets for many
elements of these families are generalized Sierpinski gaskets and that
one, and only one element in the degree three family has a Julia set
homeomorphic to the Sierpinski gasket. This talk is based on the paper "Rational Maps with Generalized Sierpinski Gasket Julia Sets'', written by R. L. Devaney, M. Moreno Rocha and S. Siegmund, 2004.
