214. Video of the day: triumphs and challenges for modern cosmology
This is a lecture given by J. Peebles at UC Berkeley, very clear and fun to listen. The video is a bit too dark, though, so you will probably want to turn off the light.

Galactic cold dark matter substructures: talk http://snipr.com/atf44 #darkmatter #cosmology # @KristyKiernan Yes and no. Fame is generally more attractive than genuine “pleasure of finding things out” (as Feynman called it)… in reply to KristyKiernan # @KristyKiernan … so generally famous physicists spend more time for publicity than for research. in reply to KristyKiernan # @KristyKiernan [...]
212. Video of the day: exploring black holes – lectures at MIT
Lectures by Edmund Bertschinger and Edwin Taylor (as well as actually many other people including Alan Guth) given in 2003. The technical level is “basic”.

Hoho, Sabina Hossenfelder wrote a paper with Lee Smolin: http://arxiv.org/abs/0901.3156. #blackhole #informationloss # They are trying to solve the black hole information loss paradox. # The paper is from the category “I did not solve anything, but I still want to write about it” # CV on Barack Obama and genetic determinism: http://is.gd/ho9b #obama # [...]
210. Video of the day: inside LHC
What can I say? Unless they’ll finally start colliding hadrons and discover Higgs (at least ) in the near future, the thing will remain what it is now – an overly complicated labyrinth of corridors and tubes
209. Gmail can now work offline
Sorry for the offtopic, but as I know, many of you (as well as myself, of course) currently use Gmail as their main email account. Is Gmail the most popular email platform among scientists? May very well be, support of conversations is too attractive I have no doubts that many times the fact that your [...]

Sorry for being quiet, has _so much_ exciting work to do # I’m a kind of back. Still overwhelmed by the amount of work to do, maybe will tweet a bit rarer for a couple of days. # If you ask me something, please don’t be upset if I’ll not reply immediately, I am kind [...]
207. Edward Farhi explains at Google why physicists need LHC
It’s great that Googlers are interested to hear talks by science experts, maybe it will help them to understand what is actually related to science and what is not Because right now the ads that AdSense serves to science related sites and blogs are terrible – to the degree they can be hardly called contextual [...]
206. A conference on black holes at PI
A very interesting conference organized by Rob Meyers, Herman Verlinde and Jaume Gomis takes place currently in PI. The topic of the conference is related to information loss in black holes and unitarity of quantum gravity in general (the one that I tried to discuss so unsuccessfully on the blog in December – I am [...]
205. Multifractality and metal-insulator transition
This is a guest blog post by Matthew Foster from Rutgers about his recent paper arXiv:0901.0284v1 [cond-mat.dis-nn]. Dmitry. In most electronic materials, impurities and other defects (“quenched disorder”) play a dominant role in shaping transport phenomena. Of particular interest has been the interplay between multiple impurity scattering and quantum interference effects. The scaling theory of [...]
