Where Will We Hear About The Higgs First ?

Aug 14 2009 | comment(s)

The World Conference on Science Journalism held in London 2009 has its own web site, of course. Today they were so kind to let me know they had published there the recordings of all sessions, among which was the one where I gave my speech. The session title was "Blogs, Big Physics, and Breaking News", it featured Matin Durrani as chair, and Matthew Chalmers, myself, and James Gillies as speakers. The abstract ran as follows:

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

$Dibosons Keep Blossoming In CDF$

Dibosons Keep Blossoming In CDF

Aug 13 2009 | comment(s)

A couple of months ago I wrote here about the first observation of a process called "diboson production", a quite rare occurrence in hadronic collisions: for the first time, the CDF collaboration could observe that rare process in events containing hadronic jets, which are usually riddled by enormous backgrounds.

The Nasty Paragraph-Vaporizing Key Sequence

Aug 12 2009 | comment(s)

Enough. I have lost to hyperspace too many paragraphs of my scribblings -here, as well as elsewhere- and I cannot stand it anymore. I need your help.

I write on a SONY VAIO laptop, with an English keyboard. The bottom row of keys has the "ctrl", the "Fn", the "windows" key; the second row has the shift key first; and the third row has the "caps lock" key. This information is relevant for what I am about to explain.

It turns out that sometimes while I write I type some nasty combination of shift, caps lock, or other keys in the thereabouts, together with some normal key I am typing at the same time, and the whole paragraph I am editing instantly disappears, vanishing into hyperspace.

Watch The Perseids Tonight!

Tonight you have a chance to contribute to science -namely, the knowledge of our solar system- and have a lot of fun at the same time. Do you want to know how ? Then please read on.

Comet Swift-Tuttle (left, courtesy NASA) may be far away by now, but the debris that gets thrown out in space during each of its passages in the proximity of our Sun traces the full elliptical orbit of the comet, like droplets of sweat of an athlete running the 10,000 meters in a stadium. And tonight, the Earth is going to plunge in the core of the filament of debris following the comet's orbit.

The Say of the Week

"Full many a gem of purest ray serene
The dark unfathomed caves of ocean bear;
Full many a flower is born to blush unseen,
And waste its sweetness in the desert air."

Thomas Gray, "Elegy Written in a Country Churchyard", vv. 53-56. I have always loved these lines, and besides, as I wrote a few years ago, "The relevance of these verses to the general melancholy of the Higgs hunter at the Tevatron is obvious… Suffices to say that the Tevatron is currently producing of the order of 20 Higgs bosons per day in CDF and D0, and yet they blush unseen, born by dark unfathomed caves of

The Continuing Search Of A Dark Site

Aug 09 2009 | comment(s)

Amateur astronomers fond of visual observation of faint galaxies and other fuzzy treasures of the night sky are always in search of the best observative site, where to drag their large Dobsonian telescopes.

Unfortunately, their road is always uphill - also in a metaphorical sense: light pollution is growing everywhere at a disturbing rate, and it has already erased all but the brightest stars from our urban and suburban skies.

Many of our kids grow without having seen the Milky Way, and the few who are drawn to astronomy are surprised to realize, from the tales of older dogs like me, that it did not use to be that way.
