The past couple months I’ve seen announcements of the founding of two new cosmology centers at US universities, and I realized that there has been quite a lot of this going on over the past few years here in the … Continue reading →

If you’re interested in particle physics and not regularly reading Tommaso Dorigo’s blog, you should be. His latest posting reports on incendiary claims by Michael Dittmar of the CMS collaboration that recent Tevatron Higgs mass limits are wrong and not … Continue reading →

Today is the fifth anniversary of the start of this blog, something that has caused me to go back and take a look at some of the early postings, and meditate a bit on what has happened during the past … Continue reading →

It’s becoming clear what the hot new topic in particle theory is these days: the use of twistor space methods to try and understand scattering amplitudes in Yang-Mills and gravity theories, especially the maximally supersymmetric versions. This evening on the … Continue reading →

LHC media fever continues this year, with at least three books out or on the way: The Quantum Frontier: The Large Hadron Collider by Fermilab experimentalist Don Lincoln. Collider: The Search for the Worlds Smallest Particles by Paul Halpern. and … Continue reading →

Steven Weinberg has a new preprint out entitled Living with Infinities, which is the written version of a recent talk given in memory of Gunnar Källén. Källén was a Swedish mathematical physicist, who died in a plane accident in 1968 … Continue reading →

Lots of wonderful blog postings about math and physics out there worth reading, with a small sample including these: Jester on SUSY and the Higgs. Dmitry Podolsky has some very useful guests posts on various topics, including chirality on the … Continue reading →

I was recently looking up references about the history of Yang-Mills theory in order to write about it here, and one thing I ran into was the Wikipedia entry for Yang-Mills theory. It has three sections, the first two of … Continue reading →
