223. Starting dS/CFT: Hilbert space
Since I was recently thinking of the dS/CFT correspondence, I find it natural to also start discussing facts and hypotheses related to dS/CFT and other gauge theory – gravity dualities on the blog. In what follows, we will mostly discuss 4-dimensional gauge theories. First of all, what is the motivation for us to look for [...]

@EtchedHeadplate AI is like nuclear energy, once you invented it, you inevitable use it irrespectively to philosophical and ethical cons.;-) in reply to EtchedHeadplate # Why water is blue? http://snipr.com/b2qzp #optics # Michael Peskin on John Updike: http://twurl.nl/x2rly7 Sad.I like his Rabbits very much #updike # David Berenstein on units and order of magnitude estimates: [...]
221. Turbulence: Kolmogorov law derived in one line
As you surely understood from the previous post, today is hydrodynamics and turbulence Sunday on NEQNET. If so, let me still 5 minutes of your precious time discussing the physics of developed turbulence. The latter is very complicated. And today is Sunday. Do I really have to overload your brain on Sunday with exceedingly technical [...]
220. Video of the day: fluid mechanics
Regarding the last video, NEQNET has to acknowledge that smoking cannot be considered a healthy habit! As for the first two videos – is it a simulation or something else? Tell me what you think.

218. Implemented Facebook Connect!
Maybe, some weeks ago some of you have noticed a frame in the sidebar of NEQNET that looked like The frame then suddenly disappeared again It actually contained the implementation of Facebook Connect on NEQNET, and the buggy piece of junk did not want to work as it supposed to. It took about three weeks [...]
217. Video of the day: standing waves
Sorry for unpleasant sounds, but symmetry patterns are quite fascinating I have actually tried to do something like this at home when I was a boy. Memories, memories…

215. Scientific computation in the cloud
This is a guest blog post by Lukas Svec who is working on high performance computing related problems in the University of Washington together with F. Vila, J. Gardner and J. Rehr. I thought that their work is rather cool and decided to learn more about it (whether we want it or not, cloud computing [...]
