Bayesian Inference in the NY Times
·
In today’s Sunday NY Times Magazine, there’s a long article by psychologist Steven Pinker, on “Personal Genomics”, the growing ability for individuals to get information about their genetic inheritance. He discusses the evolution of psychological traits versus intelligence, and highlights the complicated interaction amongst genes, and between genes and society. But what caught my eye…

Planck scanning strategy
·
OK, this is going to be very technical. In his comment to my last post, my colleague Ned Wright asks a couple of important questions about the way that the Planck Surveyor satellite is going to observe the sky. In the spirit of Mark Trodden’s question about the use of blogs in the research process,…

Nobel Prize 2006: The Cosmic Microwave Background
·
News flash: John Mather and George Smoot, two of the scientists behind the COBE Satellite, have won the 2006 Nobel Prize in Physics for their measurements of the average temperature of the CMB and the fluctuations about that average. (Here’s one self-aggrandizing reason why I find this particularly exciting.) The average, measured by the FIRAS…

More cosmology prizes

The Balzan prize, worth 1,000,000 Swiss Francs, was just awarded to Andrew Lange and Paolo de Bernardis for their work as the original Principal Investigators of Boomerang, which, in 2000, produced the first high-resolution maps of the Cosmic Microwave Background and allowed a definitive measurement of the curvature of the Universe, in the sense of…

Cosmology in the Mediterranean
Like fellow-blogger Mark Trodden , I’ve just spent the week at scientific meetings in Ischia, an island off the coast of Naples. The first half of the week was for the yearly consortium meeting of the Planck Surveyor satellite. Although still endangered by further delays, we expect the satellite to be launched in early or…

Boomerang
·
A couple of weeks ago, my colleagues in the Boomerang Collaboration, spread out over the US, Italy, Canada, France and the UK, released five papers analyzing the data from the latest flight of the Boomerang instrument, over Antarctica in January 2003 (check this out for information from my fellow Boomerangers on what it’s like down…
