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 is the way of the future as Google proves very effectively so far). Please also consider this post as a kind of press release for the code that the group of John Rehr has developed. Dmitry.

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.

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”.


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 :-)

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 advertising :-) Check out for example Lubos’ blog – he has all kinds of funny ads like “Physicsofthemind.net” and “Guru Krishna Brahaburatiobha is your true teacher” etc. etc. LOL

196. Video of the day: How big is the Universe?


194. Another quantum flapdoodle video: BBC on bubble universe

Even features Nima Arkani-Hamed and Lisa Randall :-)


192. Video of the day: Michio Kaku on Multiverse

What I really wonder – is it actually a trend that actively working physicists figure out how important nowadays is publicity, they commit themselves to getting more publicity and then suddenly, when they finally get their publicity, they are not actively working physicists anymore? Is a human too much of a social creature? Is too much socializing able to kill “the pleasure of figuring things out”?

184. Scientist’s gadgets: Polycom

Dear readers,

yesterday you did not have the pleasure to read (or were not disappointed by :-) ) a new post at NEQNET, but I do have a good excuse – first time in my life I have delivered a 1 hour teleconference seminar overseas. I did need some time to prepare the presentation as well as to deal with technical problems related to the telecon connection. Apart from sharing my impressions, I consider this post as
notes for myself, so that I can easily reproduce the process of telecon connecting in the future.

181. Technological singularity is really near

Thanks to @itscomplicated.


175. Holographic principle for dummies

Since today is Sunday, nobody should be allowed to overload your brain with too technical discussion of a new paper in ArXiv (there are no new papers till Monday, anyway!). But does it mean that I will devote part of this Sunday to posting something about financial crisis instead of science? No way! :-) Since, as generally accepted, Sunday should be devoted to fun, let me have some physics related fun.

172. Color glass condensate and glasma

I am currently reading a paper that, I should admit, I absolutely fell in love with – the one by Larry McLerran called “A brief introduction to the color glass condensate“. What is the reason for me to show up warm feelings? This is because the concentration of non-trivial physical ideas per page is so enormously high in the paper, because the emphasis is on physics and physical ideas rather than on formalities or model building, and because Larry typically just shows you the tail of the idea hiding its body in references – this keeps my mind always focused (clearly, I don’t want to go through tones of references to understand what physics is about :-) )
