I have been lagging behind lately with my usual browsing of other physics blogs. So let me catch up here and suggest a few posts which should be interesting to read.

• Peter Woit is always an extremely well-informed source of information. In a post titled "The Entropy Decade" he recently discussed how the 2010s appear to show a trend: entropy appears to be a concept that will yield more information about the universe and fundamental physics. In another he has a wealth of information on recent articles and sources.

I have many friends around the world. Some of them are far away, some live close by; but it is not the spatial separation what determines how often we meet, talk, or spend time together: it is rather a combination of chance, will, and expendiency. There are friends who live one block away which I have not seen in ages, since we do not even bump into each other, as we get out to work and return home at different times of the day. And friends who live in another continent, which I meet every time I travel there. And the Internet has simplified things, but not entirely removed the problem.

"On the infrequent occasions when I have been called upon in a formal place to play the bongo drums, the introducer never seems to find it necessary to mention that I also do theoretical physics."
