62. Two decisions and the worth of US economy
Hi friends
Today I would like to continue my non-specialist analysis of the global financial crisis, its origin and consequences. (…)

52. Introduction to non-gaussianities (Inflationary perturbations 6)
This post is the next in the series devoted to study of inflationary perturbations. I discuss the physics of non-gaussianities at the introductionary level, explain the shape of non-gaussianities and estimate their order for a single-field inflationary model.
47. Planck 2008: First and second days
First and second days of the PLANCK 2008 conference: flavor physics, RS phenomenology, WMAP, bigravity, WIMPonium, black holes and number of species.
27. Eye on ArXiv: 24 Apr 2008 - Detection of dark matter?
There was a lot of buzz recently (including the paper in New York Times) concerning the claim by DAMA/LIBRA team - they detected dark matter interactions with their detector at the level of 8 sigma
Their approach is the following: they try to find annual modulations in their DM signal (interaction of WIMPs with the material of their detector) due to fact that Earth is orbiting around the Sun. (…)
24. Inflation: description in terms of hydrodynamics (Inflationary perturbations 4)
This post continues my lecture notes on large scale structure, cosmological perturbations and inflation. The last post in this series was about the problem of initial conditions in FRW cosmology. (…)
17. Beginning inflation: problem of initial conditions in cosmology (Inflationary perturbations 4)
This is the next post in the series based on my lectures on inflationary perturbations and large scale structure given at the University of Helsinki. Today we will finally start to discuss the physics of inflation and will focus on known problems of Hot Big Bang Cosmology.
Death of Arthur C. Clarke
Arthur C. Clarke, one of the best science fiction authors of 20th century, died today at Colombo Sri Lanka. (…)
5. The Universe is expanding (Inflationary perturbations 1)
This is the 3rd post in the series based on my lectures on inflationary perturbations at the University of Helsinki (previous ones can be found here and here). (…)
4. Large scale structure of the Universe. In other wavebands (Inflationary perturbations 1)
In this post, I will briefly describe what astronomers see on the sky in wavebands other than optical as well as what observations in other wavebands are especially good for. (…)
2. Large scale structure of the Universe. In visible light (Inflationary perturbations 1)
This post is the first one in the series devoted to discussion of the large scale structure of the Universe, inflationary cosmology and inflationary perturbation theory. (…)
