111. Talk in Munich. One interesting infrared scale in inflationary cosmology

I am back to Helsinki, was not this visit really short? :-) For those of you how were unable to come to the Sommerfeld Center in Munich to hear my talk and for those of you who were there but did not understand it ? I decided to put the outline of my talk on the blog. The [...]

109. Two horror movies: one documental, another – Hollywood

A day before my departure in Munich we watched Shyamalans The happening recently released. Personally, I like Shyamalan, especially Six sense and Unbreakable, but this one was a disaster. First of all, the acting – it was just absent. Second, the story – it was not scary at all, instead, it was stupid (SPOILERS below, [...]

108. How stringy is QCD string?

I am in Munich now, so please forgive me for being a bit quiet As I’ve explained in this small introduction into criteria of confinement, breaking of the chromoelectric tube (string) connecting heavy quark and antiquark happens through the production of a pair of light quark and antiquark in the strong chromoelectric field. The physics [...]

107. New “Ender in Exile” by Orson Scott Card

Sorry for the off-topic but I am actually a HUGE fun of the Ender series by Orson Scott Card. I think I’ve read the original “The Ender’s game” around 2000 and Card immediately acquired another infinitely faithful worshipper – every single book in the series was bought afterwords, with some disappointments, but without second thought [...]

106. Criteria for confinement. Wilson loop – getting more technical

Last time we have discussed a bit the behavior of the Wilson loop expected in the confinement and deconfinement phases and have concluded from simple physical considerations that the first one corresponds to the area law, while the second – to the perimeter law. Let us now show directly that the Wilson loop VEV satisfies [...]

105. And to scare you even more…

Overall traffic (all US roads and streets) has dropped down 4.4% (equivalent to 10.7 billion vehicle miles) for September 2008 (compared to September 2007). This sounds somewhat funny considering that the price for gas in US is down by about 50% from its maximum. What would that mean? Via Andrei Simonov.

104. World crisis – looking for a job?

US unemployment claims surged to a 16-year high, government data showed Thursday, adding to growing alarm as companies worldwide shed workers in the global economic downturn. Initial jobless claims soared to a seasonally adjusted 542,000 in the week ended November 15, the highest level since July 1992. The weekly US jobless claims report by the [...]

103. Criteria of confinement. Wilson loop – physical discussion

It is often said that the most physically relevant criterion of confinement is the behaviour of the potential between two fermions: confinement implies the linear growth of potential between two charges with distance. Is it really so? In a gauge theory with fermions in the fundamental representation and the gauge group (, (5) i.e., the [...]

102. Advice, by Jim Kotsybar

And here comes the congratulation from the Singer of Physics James Kotsybar! Unfortunately, all poets are shy –   he always prefers to interact over email. However one tries to advise, The results only antagonize, Yet the moral that’s missed Is to never insist that one’s own ideas are the most wise. Just thought you [...]

101. Confinement. Extremely naive introduction

So, as I have promised last time, I am starting to collect my thoughts on the problem of quark confinement here. Actually, if things will go well with writing, I shall want to make a little review paper out of it. So, why should you, fellow reader, even be interested in the problem of quark [...]
