# Who Underestimates Their Systematic Uncertainties ?

Jun 07 2009 | comment(s)

It is a well-known fact that it is much easier to measure a physical quantity than to correctly assess the magnitude of the uncertainty on the measurement: the uncertainty is everything!

A trivial demonstration of the above fact is the following. Consider you are measuring the mass of the top quark (why, I know you do it at least once a week, just to keep mentally fit). You could say you have no idea whatsoever of what the top mass is, but you are capable of guessing, and your best guess is that the top mass is  twice the mass of the W boson: after all, you have read somewhere that the top quark decays into a W boson plus other stuff, so a good first-order estimate is 2x80.4= 160.8 GeV.

# Your Thoughts Needed on Blogs, Big Physics, and Breaking News

Jun 06 2009 | comment(s)

In four weeks I will speak at a very interesting session of the World Conference on Science Journalism 2009, an event that takes place in London from June 30th to July 4th. Together with James Gillies (head of Communication at the CERN laboratories) and Matthew Chalmers (freelance science journalist, formerly featured editor at Physics World) we will discuss the following theme:

## Blogs, big physics and breaking news

Summary: How are blogs changing the way science news develops and is reported? The commissioning of the Large Hadron Collider at CERN will offer a telling case study over the next few years. Who will be first with news of the fabled Higgs Boson, and how will we know if they're right?

# Is The Standard Model Failing Us In The Bs Sector ? Not Really, Say New Tevatron Results

Jun 04 2009 | comment(s)

It feels good, for a die-hard sceptic like I am, to live and let unexplained phenomena die. The phenomena in question are measured deviations from the predictions of the Standard Model (SM), our wonderful theory of subnuclear interactions, which has been condemned to fail by theorists soon after its construction, but continues, disappointingly for many, to succeed in explaining experimental results.

# Black to move: what would you play ?

Jun 01 2009 | comment(s)

The following position arose from a blitz chess game played on the Internet Chess Club this afternoon. I am white, and black is to move.

As you can see, material is even; white has all his pieces but the Rd1 trained against the enemy kings' shelter, a strong knight on f6, and is threatening to win an exchange with Nxe8 -however good or bad that move may be, given the strength of the knight in the game position.

# Berlusconi for The Times: a Chauvinist Buffoon

Jun 01 2009 | comment(s)

As elections to renew the european parliaments get closer, the political arena in Italy fails to deal with the matters that should interest voters, and instead concentrates on the behavior of Italy's prime minister, Silvio Berlusconi.

In a crescendo of events, each of which could have brought less gutsy politicians to resign, the italian press is getting totally dominated by the personal matters of the prime minister. Let me give a brief summary below.

A trial proved that Berlusconi had corrupted an English lawyer, Mills, to get a false testimony from him; a law masterfully crafted by Berlusconi's lacqueys only a year ago is now preventing his impeachment. Berlusconi's wife Veronica Lario publically announces she is asking for

# Just Got Un-Christened

May 31 2009 | comment(s)

The catholic church has long lost its race against islamism for the religious institution with more adepts. And they ache for it: you can tell from their resentful remarks on the matter. Bishops and spokespersons of the Vatican have been recently reported to say that the data need to be verified, that the number of muslims is inflated, that there is no clear record... The fact is, the data come from the World Christian Database, a US institute which is hard to refute. In 2007 it already estimated muslims to beat catholics 1.322 to 1.115 billions.

Here is what I reported on the matter two years ago:
