On my way back to CERN from Fermilab (yes, I am betting on two tables at a time these days, as our Poker-addict friend Garth Sundem suggests), I made a 7-hour stopover in New York. Originally this was meant to save money to my employer, because other combinations costed more than the Swiss ticket I found. But I made virtue of necessity, and organized a meeting with my friend Peter Woit in the West Village. It turned out that I picked the right day for my visit.

Chessplayers are a strange lot. Those who get attracted by the game and end up sticking to it, making it the game of their life, are typically intelligent, creative thinkers; yet among them one may usually count a unusually large number of nutcases. It is not a secret, for instance, that several of the best chess players of the past were disturbed souls. Whole books have been written on this topic (see for instance the famous "The psychology of the chess player" by R.Fine), and I cannot offer any meaningful contribution here. However, I can tell you the personal story of the worst moment of mental insanity in my chess career.
When I became an amateur chess player and I enrolled in the "Esteban Canal" chess club in Venice, about a quarter of a century ago, I met and got to know personally dozens of people sharing my interest for the game of the kings. Many of them became good friends of mine, but only maybe two or three have made a permanent dent in my soul and have stayed in my heart since then, despite our lives took different routes. Among this small subset was Francesco, universally known as "chicco" by all those who loved him.


The job of experimental particle physicist is strongly correlated with worldwide travel. Paid for and self-inflicted, sure. But not exactly always pleasant, nor to exotic destinations. In fact, experimental facilities are usually located in notably un-fancy places. The Chicago suburbs, country at the border of Switzerland and France, a mine underground in a God-forgotten place, not to mention the South Pole. One learns to take it as part of the package.
The Fermi collaboration released yesterday a paper describing their measurement of the electron and positron flux of cosmic rays. Simultaneously, a second paper was published by the HESS collaboration on the very same topic. Together, these two important new articles provide the means for a significant advancement in our understanding of the spectrum of electrons and positrons from nearby sources.

It is especially meaningful to consider the two results together because the two instruments are as different as salt grains and tequila. Let me see where to start:


This morning I signed a contract with INFN, the Italian Institute for Nuclear Physics, which grants me tenure in the role of research scientist. Start date: 05/04/2009. End of penalty: never.

Am I happy about it ? Maybe I should, but I have to confess I feel absolutely nothing - a void. Signing the contract felt like signing the receipt of a mediocre meal. Lest I get flamed, let me explain why I am not rejoicing, nor  am ordering a box of Dom Perignon.
