314. FDT-violation in colloidal glasses under shear
Matthias Krueger is a PhD student of Matthias Fuchs (U. of Konstanz). His interests include soft condense matter (that’s what this post will be about) and mesoscopic physics. Dmitry. It is a pleasure for me to follow Dmitry’s invitation and to write a post about the paper which Matthias Fuchs and I have recently written [...]
313. Video of the day: Susskind’s lectures on general relativity 7
Again – just posted. In this lecture, Susskind continues to discuss parallel transport, covariant derivatives and curvature (last time he has focused on 2-dim surfaces, this time he turns to higher dimensional case and finally introduces curvature tensor). He also discusses 4-currents, charge conservation and energy-momentum tensor (next time, I guess, he will introduce Einstein [...]
312. Turbulence. Statistical approach 2
Let us continue our brief discussion of stochastic approach to description of developed turbulence. 3. Kolmogorov scaling One of the most important and beautiful results of stochastic approach is Kolmogorov scaling. Earlier, I have already discussed Kolmogorov’s turbulence on the blog in details, let me ramble about it today a little bit more. The base [...]
311. Video of the day: LHC and search for the Higgs
A rather old promo video about LHC, which, I think, again may be considered interesting in light of recent news from CDF/D0 regarding constraints on the Higgs mass (no Higgs with a mass between 160 and 170 GeV, which leaves the only possibility that it is rather light albeit heavier than 114 GeV). Video features [...]
310. Turbulence. Statistical approach 1
Let me get back again to one of my most favourite topics in physics, that is, to developed turbulence. Last time (oh my, mid February) I have tried to explain what I consider the most important (and probably hard-to-solve) open problems in physics of turbulence. Now let me list quickly several (not too promising ) [...]
309. Video of the day: Quantum revolution
from BBC “Visions of the future”. Kaku is trying to argue that humankind is at a turning point to a period in which we will cease to be passive observers of Nature. Yessss, we all will be like Dr. Manhattan
308. Dark matter via many copies of the Standard Model
The authors of this post are Alex Vikman and Iggy Sawicki. Alex is an old friend of mine (actually, a long time ago we studied English together in the same group at MIPT and even shared the same table ). After receiving his PhD from Munich U. (his advisor was Slava Mukhanov), Alex joined NYU [...]
307. Scientist’s gadgets: Tablet PC and handwriting formulae recognition
As usual, on Sunday I’ll try to feed you with as less technicalities as possible but still make the post useful for you… Today the subject of our discussion will be related to Tablet PCs and functionality they offer to a scientist (in particular, to a theoretical physicist). As far as I remember, Steven Jobs [...]
306. Video of the day: Stanford’s mobile phone orchestra
That’s apparently what they do in Stanford when they don’t study general relativity
305. First two weeks of March on NEQNET
Here is a comprehensive list of physics questions and problems we have discussed here on NEQNET during previous two weeks: 1. String theory, field theory, quantum gravity 1.1. Chiral symmetry breaking in soft wall AdS/QCD model, where Tom Kelley (U. of Minnesota) shows how explicit and spontaneous chiral symmetry breaking takes place in a particular [...]
