334. How much should you publish?
As far as I remember, it was believed that one has to publish about 2-3 papers/year during glorious and relaxing PhD years (i.e., about 1 paper per 4-6 months, not a too heavy burden indeed)… This would give necessary 6 publications in the end of the term (in Russia, getting your PhD takes 3 years) [...]
333. Periodic table of elements: video of the day
I’ve just discovered Tom Lehrer for myself – you all certainly knew about this guy, didn’t you? He is just plain amazing… I am trying to learn the song by heart, but failing so far – the rhythm is too fast for me.
332. NEQNET: last two weeks of March
Finally… This freezing March has come to the end. Why freezing? Well, for example, it featured snow storms stronger than the ones in January/February, how is that? Or temperature dropped below -15 on March 25th. Global warming? Not in Helsinki, Mr. Gore. In the mean time, the audience of NEQNET has reached 300 people (email [...]
331. Interview with Bogzabraloff brothers: science and religion
Dear friends, I have just returned from the two-day trip to sunny (well, compared to Helsinki) Italy, where I was kindly invited to interview Bogzabraloff brothers, two of the deepest thinkers of our time. I have also had a chance to take a closer look at rather nice facilities of the Vatican Observatory, by this [...]
330. Some properties of the Burgers dynamics with Brownian or white-noise initial velocity
Patrick Valageas is a permanent researcher at the IPhT (Theoretical Physics department) of CEA, Saclay. His interests include turbulence, observational cosmology (LSS formation in particular) and astrophysics. Dmitry. I would like to thank Dmitry for giving me the opportunity to present two recent papers of mine (arXiv:0810.4332 and arXiv:0903.0956), on the Burgers equation, from the [...]
329. Human Activity in the Web
Filippo Radicchi is a research scientist in Complex Systems Lagrange Lab, ISI Foundation, Turin. He is interested in non-equilibrium diagrammatic methods, RG group analysis of complex networks and community detection. Dmitry. We use to spend a relevant part of our time surfing the Web: we read news, make posts in blogs, share photos and music, [...]
328. Yield curve: video of the day
If you were unable to figure out the physics behind the a treasury yield curve, here is a very nice explanation: By the way, if you are interested in economics and are familiar with YouTube, I highly recommend subscribing to khanacademy. The guy is just great.
327. Global crisis and one more plot to think about
The following quantities are plotted here – total US GDP, investments, SP500 index and so called treasury yield curve, By definition, the yield curve is the relation between the interest rate and the time to maturity of the debt, and the yield curve above is the one for US treasury securities and US dollar interest [...]
326. House market bubble: brief update
As usual on Sundays, science will be temporarily forgotten, because I would like to share many other things with you. This Sunday I am going to talk about again only global financial crisis. You are probably eager to know how US house market is currently doing, since the it was the bubble burst on this [...]
325. Scientist’s gadgets: desktop software
Desktop software? What is this supposed to mean? – you may ask. Well if you are a fellow scientist – theoretician, to be more precise – you know very well how much time we usually spend in front of our computers. Once upon a time I have tried to make a personal estimation in my [...]
