274. Video of the day: Quark-gluon plasma at RHIC
Beautiful promo video of RHIC. Not sure what she means by “they expected to find a gas…”
273. Lattice Chiral Gauge Theories: What’s the Problem?
This is a guest post by Yanwen Shang. He was a graduate student of Gregory Gabadadze at NYU and is now a postdoc at the U. of Toronto working with Erich Poppitz. There will be actually two posts discussing lattice fermions – one today and another tomorrow. Dmitry. I’d like to thank Dmitry first for [...]

Lubos Motl on Ernst Mach: http://tinyurl.com/b2gx96 Stanleyfest at #KITP: http://online.kitp.ucsb.edu/online/stanleyfest/ . Fascinating, Joe Polchinski’s talk is definitely worth watching. http://arxivblog.com/?p=1220 – the CORONA coronograph proved to be unable to function in Antarctica and was sent back to France. What should robots do for us? http://arxivblog.com/?p=1216 A paper is out to arxiv actually explaining that. Bizarre. [...]
271. Continuing dS/CFT – correspondence. Part 2
News: It seems that there are good news for science funding in US. Cosmic Variance points out that science funding in the stimulus package was largely restored: with 3 bill. for NSF, 1.6 bill. for DOE and 1 bill. for NASA. I really hope this is final In the mean time, when we keep waiting [...]
270. Cosmological fluctuations from IR cascading during inflation
This is a guest blog post by Neil Barnaby who is working in the Lev Kofman’s group at CITA, the very same I worked 3 years ago. Dmitry. First off, I want to thank Dmitry for inviting me to write about my recent paper, arXiv:0902.0615. This work was done in collaboration with Zhiqi Huang, Lev [...]
269. Hamiltonian formulation of tetrad gravity: three dimensional case
This is a guest blog post by Natalia Kiriushcheva and Sergei Kuzmin from the U. of Western Ontario. Dmitry. Thank you, Dmitry, for the invitation to write a guest post about our recent work co-authored with Alexei Frolov and Sergei Kuzmin: “Hamiltonian formulation of tetrad gravity: three dimensional case”, arXiv: 0902.0856 [gr-qc]. We are curious [...]
268. Video of the day: Sean Carroll at Google
is talking about dark energy and dark matter: Wow, not bad, I am glad to see that Googlers get more interest in science (so that the way PageRank treats science papers will be finally improved to the point where googling a research paper becomes useful ) Via Cosmic Variance.

266. First two weeks of February on NEQNET
It seems that I did not do summary of activities on NEQNET for quite a bit Let me first quickly go through some relevant and irrelevant statistics. First of all, the number of subscribers to NEQNET has finally crossed the magic number of 200 (two-three days ago). Thank you so much, all of you, who [...]
265. Video of the day: CMS assembly animation
An old video (2003) by CERN explaining how CMS detector was assembled. Update: If you want some relatively fresh info on CMS status, listen for Giovanni Franzoni’s talk at PI.
