About Tommaso Dorigo

I am an experimental particle physicist working with the CMS experiment at CERN and the CDF experiment at Fermilab. In my spare time I play chess, abuse the piano, and aim my dobson telescope at... Full Bio

Americans, but in general scientists, and science-lovers of any country, should be proud of the achievements of the Tevatron collider, the 2-TeV proton-antiproton collider build over a quarter of a century ago under the prairie of Batavia (IL), and which is still the world's most powerful, and may I say successful, particle accelerator ever built by humans.

Ok, I know I will now enrage the supporters of electron-positron machines, in particular the one which discovered the charm quark and the tau lepton, or the ones which uncovered many mysteries of electroweak interactions in the nineties. But the achievements which the Tevatron has allowed, and the advancement of Science produced in the realms of QCD, electroweak theory, searches for new physics, B physics, are really outstanding, so much so that I cannot bring myself to making a list here. Suffices to say that some of the measurements produced by CDF and D0 with the Tevatron data will remain the best in the world for many years, maybe even a decade, into the running of the Large Hadron Collider, the CERN competitor which will start recording collisions in a couple of months.



Check out the graph above (courtesy G.Ch.), which shows the integrated luminosity delivered by the Tevatron since the start of Run II seven years ago: we just surpassed the seven inverse femtobarns mark! That corresponds to about five hundred trillion collisions delivered in the core of the CDF and D0 detectors, for a grand total of a quadrillion events! Kudos to the Tevatron scientists for this terrific goal!

Tommaso, your chart from 2002 to 2009 shows the number of Fermilab collisions increasing to 500 trillion collisions.

A corresponding chart for the total notional value of derivatives (the probably worthless things held by big banks that are causing the collapse of the USA/UK global financial system) would show a similar increase, from 2002 to 2008, to $500 trillion,
so
to try to prop up the USA/UK system, the Obama administration seems to have promised the Big Five Banks (alphabetically - Bank of America, Citi, Goldman Sachs, Morgan Chase, and Morgan Stanley) that the Treasury/Fed will print up however much money they need to cover their exposure (which as of March 2009, according to the Office of the Controller of the Currency, was about $280 trillion = more than half of the total).

Do you find it interesting that the USA seems to be on course to create dollars as fast as Fermilab creates collision events ?

If your life savings were in USA dollars, would you be happy seeing as many quadrillions of them printed as Fermilab has collisions?

PS - Could an impending disaster in the derivatives/hedge fund business be the reason that, as Peter Woit noted on his blog, "... Mathematician Jim Simons is retiring from the job of running the hedge fund Renaissance Technologies. ..."?

"Slow & Steady always wins the Race"
-- Tortoise & Hare fable

This is a famous child's fable, which has relevance to adult activities. As a trained engineer (w/PhD), I look at last year's "teething pains" of meltdown & think: "that's just typical development curve"

"There are no mistakes, only lessons. Growth is a process of trial and error;
experimentation. The "failed" experiments are as much a part of the process as
the experiment that ultimately "works"."

These lessons are constantly played out in Auto Racing (a great metaphor for Life), since a season Drivers title is a lesson in Endurance (as well as speed):

"You can't win the Race on the 1st lap [ early in Development Curve, say with the LHC ]..BUT YOU CAN CERTAINLY LOSE IT"
-- Auto Racing saying

I think the LHC is taking the role of some over-eager racers, who dive-bomb into the 1st turn & crash out of the race. Just happened to Simona De Silvestro (competitive Swiss driver in Toyota Atlantic series, was going for the 2009 Drivers Title) at the last race @Laguna Seca:

http://www.montereyherald.com/sports/ci_13543171
It was nice while it lasted — it just didn't last quite long enough.
Simona De Silvestro carried an eight-point lead into the championship battle of the Cooper Tires Presents The Atlantic Championship Powered by Mazda, trying to be the first woman to win a major closed-course auto racing championship in North America.

On the opening lap of the season championship finale at Mazda Raceway Laguna Seca, De Silvestro and 2008 series champion Markus Niemela tangled in the Corkscrew, putting De Silvestro into the tire barrier and ending her day.

That opened the door for pole-winner John Edwards to not only win the race on the final day of the Monterey Sports Car Championships, but also the season championship, becoming the youngest to do so in the 36-year history of the series at age 18.

In the process, he leapfrogged his Newman Wachs Racing teammate Jonathan Summerton and De Silvestro to collect the championship hardware

I'm friends with Simona on Facebook & was bummed out to see her comment on how her race got "thrown away". Same thing happened to Katherine Legge (talented UK open-wheel racer). Like Simona, she had breakthrough 3 wins in 2005: won her 1st race @ Long Beach Grand Prix, & won 2 straight later on in the year. Because of Marketing pressures (Champcar was competing with IRL, the "split" series for Indycar), Katherine was offerred a jump to Champcar (bigger car, bigger engine, etc). Kat thought she needed 1 more year in Toyota Atlantics, but how could she refuse such an attractive offer? Turns out she was overwhelmed, had issues in Qualifying, which created poor starting positions, & the year was not good. She also had a bad crash at Road America. SHe was demoted to a lesser team in 2007, & utlimately left Champcar (now racing DTM touring cars in Europe) I know her, really feel bad -- She deserved better. Everyone is waiting for the breakthrough female driver in the big leagues (Indycar, Formula 1) to be competitive with the men. Simona was certainly doing that this year. Another driver to watch is Ana Beatriz (Brazil) who is competitive in Indy Lights, another friend of mine on Facebook.

"The Journey IS the Reward"
-- Chinese proverb

The LHC is early in development, & like "developing a race-car" it will take time. Teamwork is involved, so that involves people.

"In the end, it all comes down to People"
-- xxx, Pentagon military analyst

"It's hard to find Good People"
-- Dave S., Ford Class 8 drivers champion, SCORE series

"It's all about TRUST [ trusting that your teammate does his job, & you do yours ]"
-- Mario Andretti

In the above analysis, Tommaso correctly attributed Fermilab's success to great teamwork. There is a famous Chicago/IL based Indycar team by the name of Newman-Haas Racing. They are consistently a threat to win & have won 4 straight Drivers titles (Sebastien Bourdais, French driver). He was hired because his Mechanical Eng degree, lets him assist the engineers "setup a car" for Qualifying & Race. He therefore has a "stable car", where he can use his mistake-free consistent driving style to be a threat for P1.
