Today is a good day: I can rest in peace without working out my daily share of science popularization here, because I have something better to do, which will have a much more sizable positive effect for the diffusion of particle physics. In fact, I hold in my hands a brand new copy of Gian Francesco Giudice's book, "A Zeptospace Odyssey - A Journey into the Physics of the LHC". All I have to do is to explain to you why you really should buy, read, and give as a present this book to all your friends.

In my friend Peter Woit's blog I read an interesting account of an interview to Greene and Kachru, two leading string theorists. Here is an excerpt, which Peter got from the World's Science Festival:
John Hockenberry, the panel’s moderator, asked Greene if he thought experimental evidence would come during his lifetime.
“I’d be surprised,” said Greene.
“And in your lifetime?” Hockenberry asked Kachru.
"I do not understand why journalists and others want to know about the latest discoveries in physics even when they know nothing about the earlier discoveries that give meaning to the latest discoveries"
Richard Feynman (quoted by G.F.Giudice, "A Zeptospace Odyssey", Oxford University Press 2010)
Ah, the joy to see bosons in our first 7-TeV proton-proton collisions at LHC! The CMS experiment has released two days ago its first results on W and Z bosons, plus many other riches. Of course, these plots are only demonstrative, since the statistics is still ridiculously poor if compared with the wealth of data available at the Tevatron. But still, these are collisions at 3.5 times more energy, and the machine is doubling its luminosity every week or so, so I expect that very soon the distributions will stop looking rough and will start containing real information, to be converted in meaningful measurements of the relevant physical quantities.

It is Sunday morning, and I am about to leave for a day on the beach, the first of this busy 2010; so this post will be shorter than I would like it to be... There would be lots to say about exclusive physics at colliders. But I still want to share with you a figure extracted from a recent
4-page preprint article by James Pinfold, who nicely summarizes the signals and searches for exclusive processes at the Tevatron proton-antiproton collider.
After two years spent saying that Italy has a strong economy and is doing better than the rest of Europe, and strongly criticizing whomever tried to warn that the economical crisis was not over yet, the Italian government led by Silvio Berlusconi has made a sharp turn. The buzzword is now "avert the Greek risk", and while painting dreadful scenarios Berlusconi and his ministers have crafted a finance law that drags over 30 billion euros mostly from salaries. The anti-Robin-Hood strikes again.
