Astrostatistics at the Royal Astronomical Society
·
This week I’m co-organizing a meeting at the Royal Astronomical Society in London, “Novel methods for the exploitation of large astronomical and cosmological data sets“. It’s an unwieldy title, but we’ll be discussing the implication of the huge flood of astronomical data for cosmology and astrophysics. How do we deal with the sheer volume —…

Consider a Spherical Cow (Company)
One of my old friends from graduate school, and a colleague to the present day, Lloyd Knox — whom you may remember from such cosmology hits as the Dark Energy Song — has started an initiative to create “short documentary videos to demonstrate the explanatory power of simple physical models and to help us understand…

I spent part of this week in Paris (apparently at the same time as a large number of other London-based scientists who were here for other things) discussing whether the European CMB community should rally and respond to ESA’s latest call for proposals for a mission to be launched in the next open slot—which isn’t…

We get most of the official feedback on our teaching through a mechanism called SOLE — Student On-Line Evaluations — which asks a bunch of questions on the typical “Very Poor” … “Very Good” scale. I’ve written about my results before — they are useful, and there is even some space for ad-hoc comments, but…

O SOLE Mio
I just received the SOLE (Student On-Line Evaluation) results for my cosmology course. Overall, I was pleased: averaging between “good” and “very good” for “the structure and organisation of the lectures”, “the approachability of” and “the interest and enthusiasm generated by” the lecturer, as well as for “the support materials” (my lecture notes), although only…

Teaching Cosmology
I’ve just finished teaching my eleven-week winter-term Cosmology course at Imperial. Like all lecturing, it was exhilerating, and exhausting. And like usual, I am somewhat embarrassed to say that I think I understand the subject better than when I started out. (I hope that the students can say some of the same things. Comments from…

Andrew Lange, Huan Tran
The cosmology community has had a terrible few months. I am saddened to report the passing of Andrew Lange, a physicist from CalTech and one of the world’s preeminent experimental cosmologists. Among many other accomplishments, Andrew was one of the leaders of the Boomerang experiment, which made the first large-scale map of the Cosmic Microwave…

Bayesian Methods in Cosmology
·
The perfect stocking-stuffer for that would-be Bayesian cosmologist you’ve been shopping for: As readers here will know, the Bayesian view of probability is just that probabilities are statements about our knowledge of the world, and thus eminently suited to use in scientific inquiry (indeed, this is really the only consistent way to make probabilistic statements…

Exam nightmares
The students in my cosmology course had their exam last week. There’s no doubt that they found the course tough this year — it was my first time teaching it, and I departed pretty significantly from the previous syllabus. Classically, cosmology was the study of the overall “world model” — the few parameters that describe…

Ada Lovelace Day — Henrietta Leavitt
·
Today is Ada Lovelace Day, “an international day of blogging to draw attention to women excelling in technology.” I — along with more than a thousand other people — have pledged to write about a female role model in technology. Ada Lovelace was Byron’s daughter and worked with computer pioneer Charles Babbage on his “Computing…
