#TASI, day 7

Today was my second day of lecturing at TASI, and I gave one (morning) lecture, on the use of MCMC sampling. In the afternoon, I looked at (for the first time) the GALAH data on detailed element abundances of stars. I looked at the question of whether the chemical abundances could be used to predict the Galactocentric radii. The idea is: If the gas involved in star formation is azimuthally mixed, there ought to be relationships between radius in the disk and chemical abundances. They didn't jump out! I have various ideas about why, but for now this will be back-burner.
