I had an interesting discussion over lunch with @bmutlupakdil about students/postdocs and the fear of asking questions in talks/#aas233 sessions, so I thought I’d share some of my advice in case it is useful: 1) there’s a simple way to “practice” before you are ready to speak: @bmutlupakdil sit in the session and write down (privately) the questions you *would* ask aloud, even if you only write them down. 2) take a look at the questions and compare them with those that do get asked by people in the room. What was different (or the same!) about the ones you wrote?

New @Planck results out today. Everybody get reading!! cosmos.esa.int/web/planck/pub… #cosmology #CMB #astrotastic @Planck This paper gives a comparison between likelihoods for the data - generally in agreement although for some parameters there is a systematic difference of 0.5sigma between likelihoods on the same data.
