Had a great visit to UC Davis, where I gave a talk to the cosmology group (which is pretty damned large). Spent the rest of the time talking with Chris Fassnacht and Matt Auger about galaxy evolution vs. strong gravitational lensing (Auger says do the former, not the latter, because we will understand the scale factor and galaxy mass distributions better by other means within the next decade or so). Also argued with Lloyd Knox and company about my brave new world fantasy in which we have constrained realization cosmological simulations that actually reproduce all observations, exactly not statistically. They all told me I am crazy; okay it is hard, but isn't science supposed to be hard?
