Daniel Mortlock (Imperial) dropped in for the day and we spent some quality time talking about data. We don't have any project to work on, but we should! Mortlock holds the current high-redshift quasar redshift record. At lunch time, Gabe Perez-Giz (NYU) talked about computing geodesic orbits around Kerr black holes. He is a big believer in making use of symmetries, and there are additional computational symmetries if you look at closed orbits—orbits where the azimuthal, radial, and polar-angle frequencies are rationally related. If you can build a dense orbit library out of these orbits (and it appears you can), then you might be able to compute a whole bunch of stuff fast. Now show me the money!
