Who Are You Going to Call VP?

Did anyone else notice that Sarah Palin, McCain's recently-picked running mate,
has an uncanny resemblance to
Annie Potts in Ghostbusters?

Bolt of Genius

Ever had one of those months? Yeah, me too.

Anyway, it's given me more time to read the paper, where I noticed this gem in a Times article about Usain Bolt, the Jamaican runner who shattered the previous 200m record by two one-hundredths of a second, which apparently sets "new parameters on what humans can achieve":

“You have people who are exceptions,” said Stephen Francis, the coach of Bolt’s main Jamaican rival, Asafa Powell, the former 100 world-record holder. “You have Einstein. You have Isaac Newton. You have Beethoven. You have Usain Bolt. It’s not explainable how and what they do.”

Who can argue with that, and especially with using two physicists as points of comparison?

Beam in LHC

Wow this is really happening, Rama Calaga and Adam Yurkewicz are reporting live on the LHC actually putting beam in the machine. Stay tuned.

Bernese Bat Signal

We bumped into this unreal sunset/cloud/mountain configuration up on Obersteinberg in the Bernese Oberland. As I noticed this from our room, grabbed my camera, and bolted outside, everyone from the berghaus started doing the same thing. Then I got home, and noticed this:

And yes, I saw the movie last night, but didn't see any alpine sunsets anywhere -- just that crazy Joker everywhere.

Bernese Oberland

One thing I haven't had a chance to mention yet is that K and I finally took a vacation a few weeks ago, just before my trip to Bern. We managed to hike our way through a bit of the Bernese Oberland, roughly following the Alpine Pass Trail. The photos (or at least the ones we've posted!) can be found here.

Taking PHOBOS Apart

One of my BNL colleagues wanted to see these again, so I decided just to go ahead and post them online. These are the most recent photos of PHOBOS in its final incarnation, as it was when we had to take it apart in 2005 and put it in "cold storage" for a few years. You can finally see all of the various pieces of the system we usually show as a CAD drawing in our scientific talks -- the magnet, the silicon, the beampipe, etc. Frankly, while at first glance it looks quite chaotic, I find the silicon detectors themselves alarmingly symmetric and beautiful looking. And incredibly clean, which is unsurprising considering they were safely protected in a light-tight enclosure for 6 years! Enjoy.

View from Fort L'Ecluse

Still catching up from my long trip. Here are a few photos from an afternoon playing hookey from meetings. An ALICE friend of mine had stumbled onto Fort L'Ecluse years ago, on another hookey trip, and wanted to check it out again. However, this time they'd completely revamped the fort, made it into a museum, and given access to the upper fort (Fort Superieur) 1000 steps in the air. While I hadn't expected a Washington Monument level climb, it was totally worth it for the views (of Mont Blanc, the Rhone, and the Vuache) which happened to be on the most perfect day I'd seen in Geneva for quite a while. Anyway, enjoy.

For those curious, the fort is a drive about 20 minutes southwest of CERN (just between Meyrin and Saint-Genis-Pouilly, straddling the border), at a "notch" in the Jura just below Collonges, which looks like this (thanks, Google):
So it gives fantastic views towards the Alps to the east, especially Mont Blanc, which features prominently in a few of the photos.

CERN Rainbow

CERN Rainbow

I know things have been silent on this blog since before I left for Switzerland, but it's been flat out for me since that Wall-E post. First I had to get ready for my trip, which involved a week in the Bernese Oberland, a week in Bern for an ATLAS meeting, and now a partial week here at CERN getting my head around ATLAS itself. Then I had to hike up and down mountains for a week, breathing the cleanest air, drinking the cleanest water, and eating lots of swiss hiking food. I've just finished the week in Bern, which is an unbelievably nice place, especially with the weather. And now I'm holed up in a hostel room at CERN (the CERN hostel being better than many hotels I've seen) waiting out the intermittent rainstorms. Of course with crazy weather comes some crazy luck, like this circular rainbow hovering over Geneva: auspicious, no?

The BNL of the Future

I totally missed this, but the marketing for the upcoming Pixar film Wall-E has a fake website for a company called "Buy-N-Large", whose acryonym is kind of familiar to me:

I wonder if anyone at the lab is going to make the connection? Of course, this new BNL has to compete with Banco Nazionale del Lavoro in Italy, and Bare Naked Ladies, and, um, B&L Associates. But the movie seems to suggest that BnL will be all right, especially from the perspective of the far future.

Needless to say, that despite a major work trip coming up the next day, my wife and I will be lining up to catch Wall-E when it opens this week. The NYTimes article yesterday (today?) made sure that resistance would be futile, at least for us.

Physics and Politics

From 0 to 3 in 15 years is pretty good: “'If we continue to reproduce in this manner,' Mr. Foster began, and Mr. Ehlers finished the thought, 'the entire Congress would consist of physicists!'"

I actually spent time on Capitol Hill when I was in college, working for a Congressman. Fascinating time, but that was a major inflection point in my life story, when I decided to do science instead -- hoping to avoid some of the messiness of politics in my real life. Of course, do science for a few years and the messiness of it comes roaring back at you: so I really respect these guys trying to roll up their sleeves and interject fact-based reasoning into the policy-making process.

The Four Phases of PHOBOS

Of course I'm still catching up with last week, partly due to distractions this week, and partly since it took a few days for the organizers to post all of the talks from the RHIC Users Meeting. One talk which was particularly significant to me was "The Four Phases of PHOBOS" by Wit Busza from MIT, who has been spokesman of the PHOBOS experiment at RHIC since its inception in the early 1990s. He was even spokesman before PHOBOS was even a proposal, back when it was a conceptual design called "MARS", shown here to the right, which eventually became the PHOBOS experiment (side note: while MARS was actually an acronym, PHOBOS never was, even if it was presented like one). And he was there all the way through it's first incarnation as a working experiment, even in pieces (see left), through its "golden age" from 2000-2005 as a working active experiment (below), and even now as the collaboration is still analyzing the data and writing papers despite the experiment being completely disassembled.

In fact, it was also notable that last week was when PHOBOS was finally taken from BNL and brought to MIT by van (see loading photos below), where various sections will be shipped to the participating institutions -- the physics equivalent of a hunting trophy. Of course this is kind of like a hunter mounting a gun on the wall instead of the deer. Too bad you can't put a "perfect fluid" (or whatever) on the wall -- since, although small, we were an active participant in that hunt since the very beginning.

Bo Diddley

Bo Diddley, RIP.  I saw him in 2004 (where the Times photo was probably taken), at a monstrous garage rock festival on Randall's Island, impressive as ever, with a guitar I could scarcely imagine without seeing it myself, with so many knobs, sliders, levers, and controls.  Too bad no-one ever figured out how to patent a beat back in the 1950's -- he'd have died a rich, rich man.

The Gospel According to Oliver

It was hard to know what exactly to expect from this event, where Oliver Sacks was guest speaker at the Abyssinian Baptist Church up on 138th Street in Harlem as part of the World Science Festival. But pairing a short, but substantial talk by Sacks about "Music and the Brain", with a full-on gospel concert by the Abyssinian Gospel Choir, and introductions by Calvin O Butts III, an impressive speaker in his own right, made for a stellar evening. Brian Greene even gave a star turn doing his best impression of a Baptist preacher, and then took off for his Guggenheim gig downtown (anyone see that?). Even better, I had a Quantum Diarist sighting -- that's Stephon Alexander standing in the front with Jim Gates (who also was part of the Gugg event), as they were acknowledged by Butts during his introduction.

UPDATE: The TED blog has asked if they could use my photo for their report on the same event.

Dept. of Shamelessness, Part II

And before things accelerate again, just wanted to pass along a couple more pieces of good news.  On Thursday, during the RHIC/AGS Users Meeting (yes it ran all week), two things happen that don't normally Happen To Me: a certificate of appreciation for helping bring the BNL Cafe in reality (I'm still blushing -- all I wanted was a cup of coffee), and I survived the election to win a seat (one of several) to the Users Executive Committee.  Growing up, I never really thought of myself as community-minded, but something seems to have changed in the last few years.  Brookhaven is a lovely place, and RHIC a great place to work, and it's been fun to take a more active role in keeping it that way.

Moscow on the Moskva

As bookends to that trip to Dubna I took for work a few weeks ago, I managed to schedule in a couple of days in Moscow to see the sights (which are many) and visit an old friend who's been living there in recent years. Moscow was really spectacular, from Red Square to St. Basil's (pictured), and from the unbelieveable churches of the Kremlin to the futuro-bizarro restaurant atop the Academy of Sciences, with views over the city. I've posted a few photos in the usual place.

Entropy Bound in Physics World

From the department of shamelessness, I submit to you an article in Physics World about this very blog.  Really flattering that it exists at all, but gee it's sobering to hear an outside view of things (i.e. I only saw the piece today, after it had gone live)

Thank You (Faputtinme on the NYTimes Website)

Sly Stone is one of my favorites, and this is my favorite period of his career.  And his 1973  expression, surrounded by the ephemera of the modern web, is priceless.

The PHOBOS Glauber Monte Carlo

As a follow up to this post, several colleagues and I just posted a paper to the arxiv today: "The PHOBOS Glauber Monte Carlo."  This is one of those technical-sounding things, but which has had a surprising relevance to understanding actual RHIC data.  Many people treat nuclear collisions by considering the nuclei to be overlapping smooth distribution of protons and neutrons.  However, it is also reasonable to treat nuclei as clumps of protons and neutrons as individual particles, especially since that's, um, what they are.  The interesting part is that the positions jiggle around collision to collision, and those fluctuations seem to have real manifestations in physical phenomena (see, e.g., this paper).  

Anyway, there is an amusing back story here: when we were writing one of the early PHOBOS papers back in 2000, we discovered that we needed our own implementation this kind of thing.  I was on a trip to South Africa at the time, so I cobbled something together on the plane -- and this is the core of what we've now put out for public release almost 8 years later.  That said, it's not rocket science (i.e. every experiment has their own version), but despite a ream of papers and Glauber reviews, there have been relatively few codes available until now.  Enjoy.

The Physics of Privacy

Fantastic -- an anonymous donor has recently stepped up to contribute $5 million to Fermilab (via the University of Chicago) to help end its furloughs.  

It's incredible that Congress as a whole still does not appreciate the intrinsic interest high energy and nuclear physics generate outside the field.  RHIC already showed that private funding actually makes both sides look good: the donor for supporting something which promotes science and technology, and participating in the process of discovery, and the scientists for attracting the attention of powerful people outside the government.  While it clearly will never be enough to rely on private donors, it bodes well for the future of the field.

RHIC Users Meeting

Gee it's been a longer hiatus than expected.  First was that trip to Russia.  Then it's been madness finishing a proposal (more on that soon).  Then it was memorial day weekend and a trip down to the Chesapeake bay.  And now it's the RHIC Users Meeting at Brookhaven.  We've already had a full day of workshops (I attended one on various correlation measurements used to characterize jets in heavy ion collisions) and now it's an all day symposium on RHIC and its impact on Nuclear Physics.  So far nothing brand new to report, but the day has just begun.
