“I think we have it”

In honor of the Higgs announcements from CMS and ATLAS, a physics haiku I’m calling “The Heaviest Boson.”

Did you see that bump?

Standard Model wins again.

Magic number five.

Congratulations everyone!!!!

Update: The excellent radio show The World is asking its listeners to come up their own Higgs haikus. Submit yours here.

Ten physics band names

Only a few physicists have ever achieved true rock star status, but that doesn’t stop the rest of them from joining bands. Physics labs around the world play host to numerous official and unofficial rock bands, from CDF’s Drug Sniffing Drugs (last seen crying into their beers at the afterparty for the Tevatron shutdown) to Les Horribles Cernettes across the Atlantic. Below, ten suggestions for band names inspired by the history of my favorite science. Suggested styles, if any, in parentheses.

1. The Ultraviolet Catastrophe

2. The Strangelets (60s-style girl group)

3. Enrico Fermi and the Chicago Piles

4. Los Alamos Ranch School (songs to wear sweaters to)

5. Charm and Strange (acoustic duo, lots of whistling)

6. Spectral Lines (electronica)

7. I Am Become Death (metal)

8. SUSY and the Banshees (80s cover band)

9. Cosmic Ray (lounge singer)

10. Higgsino and the WIMPs

Four great physics road trips

In 2009, I went on a physics-themed road trip (and wrote about it). I didn’t know it then, but I was participating in a grand tradition. Here are four great road trips from physics history.

On the road with Robert Oppenheimer, left, and Ernest Lawrence in 1932. Photo courtesy of the American Institute of Physics.

1. Ernest Lawrence goes West, 1928. After finishing his Ph.D. at Yale and spending a few years there as an assistant professor, Ernest Lawrence hopped in a Reo Flying Cloud and headed west to a new job at UC Berkeley. Once there, he invented the world’s first particle accelerator, founded the country’s first National Laboratory, planted the seeds for American Big Science, and put the U.S.’s experimental physics program on the scientific map. (His theoretical counterpart Robert Oppenheimer arrived at Berkeley one year later in a gray Chrysler.)

2. Glenn Seaborg gets on a train with most of the world’s plutonium, 1943. Seaborg’s team isolated the first tiny sample of plutonium on August 20, 1942 at the Met Lab in Chicago. About a year later, he shipped a 200-milligram sample of element 94 to Los Alamos, where it was used in an experiment that proved it could sustain a chain reaction. Seaborg soon followed his precious sample to New Mexico to spend his well deserved summer vacation lurking around Santa Fe with his wife and most definitely NOT visiting the secret Manhattan Project laboratory up on the mesa. Headed back to Chicago at the end of July, he offered to take the speck of plutonium he had loaned to the war effort with him. Robert Wilson made the hand off before dawn in a Santa Fe restaurant, arriving, according to Richard Rhodes, “in a pickup armed Western-style with his personal Winchester .32 deer-hunting rifle to guard a highly valuable but barely visible treasure.” The less flamboyant and decidedly unarmed Seaborg simply put the sample in his suitcase and caught the train home. Soon, much larger quantities of plutonium and enriched uranium would begin arriving at Los Alamos from the production facilities in Hanford, Washington, and Oak Ridge, Tennessee.

3. Richard Fenyman ditches Freeman Dyson to chase a girl, 1948. After World War II ended, many physicists who had devoted themselves to the technical challenges of building an atomic bomb finally had a chance to tackle some of their science’s lingering theoretical problems. One of these was an inconsistency in quantum electrodynamics, the quantum field theory that described photons and electrons. Richard Fenyman published a solution to the problem in 1947, but his explanation was seemingly at odds with the work of two other scientists, Julian Schwinger and Sin-Itiro Tomonaga, and no one was quite sure how to move forward. In the summer of 1948, Fenyman and his friend Freeman Dyson took a road trip from New York to Albuquerque (what can I say, physicists ❤ New Mexico), picking up hitchhikers, getting speeding tickets, and staying in at least one brothel along the way. (Ian Sample assures us “they sought only shelter.”) When they arrived in Albuquerque, Fenyman took off in search of a girl, leaving Dyson to aimlessly travel the Southwest on a series of Greyhound buses. He eventually boarded one that would take him back to New York and, somewhere in the middle of Nebraska, suddenly saw that the three competing theories about quantum electrodynamics were actually one and the same. Quantum field theory was saved.

4. Gerry Guralnik and Dick Hagen drive to Germany to be insulted by Werner Heisenberg, 1965. In the early 1960s, the question of how particles acquired mass was just beginning to be discussed. A handful of physicists scattered across the U.S. and Europe more or less independently worked their way toward a preliminary answer, describing a field that permeates space and gives mass to some particles but not others. Gerry Guralnik, Dick Hagen, and Tom Kibble were working on this problem at Imperial College in London, publishing their first paper a bit behind the other teams in 1964. Guralnik and Hagen planned to give talks on their work the next summer at a conference hosted by Werner Heisenberg in a town outside Munich. Since they were both Americans and wanted to see more of Europe, they decided to make a vacation of it and picked up a cheap car in France. After encountering artichokes for the first time in Paris, they made their way to Bavaria, where, much to their chagrin, their work was met with “almost uniform disbelief,” according to Guralnik. Heisenberg himself called their theory “junk,” causing Guralnik to doubt his future as a physicist. If scientists at the LHC find the Higgs boson, Guralnik and Hagen will finally be proved right.

DIY Particle Physics

In honor of the blog’s new name, an article about people who build their own cyclotrons, via symmetry.

For many of those obsessed, the only way to satiate their hunger for these machines is to build their own. There are no guidebooks or instruction manuals, and if you bought the raw materials off the shelf, it would cost around $125,000. On average, amateur cyclotrons take two to three years to build.

“It didn’t take long to become obsessed….Where I would be without the cyclotron project I cannot even begin to imagine.” —Tim Ponter. Photo by Tim Koeth, via symmetry.

The amateur cyclotron builders mentioned range from high school students to college professors to Fermilab scientists. To bring down the cost of their hobby they scavenge old equipment, a technique familiar to the first cyclotron builders. Columbia’s cyclotron, for example, was built partly from salvaged parts in the 1930s. It ended its life as scrap metal.

The cyclotron’s heyday as a cutting-edge research tool is mostly over, though they are still widely used in medicine. The largest one ever built is 60 feet in diameter and is still running at the Canadian physics lab TRIUMF. The smallest involves a single electron trapped in a magnetic field and is perhaps more appropriately called an artificial atom.

Physics on the Fringe

I have a review of Margaret Wertheim’s wonderful new book Physics on the Fringe: Smoke Rings, Circlons, and Alternative Theories of Everything up today at Bookforum. Wertheim has been collecting examples of outsider theoretical physics for fifteen years, and in Physics on the Fringe she considers what drives people to try to piece together the laws of the universe entirely on their own. As she follows the life and work of the “fringe theorizer” Jim Carter, who, like many outsider physicists, rejects math-heavy field theory in favor of his own home-spun ideas, she examines the professionalization of physics, the rise of abstract mathematics, and the oft-ignored question of who has been left behind as we march toward a “theory of everything.” One of my favorite parts the book that I had to leave out of the review is Wertheim’s discussion of Michael Faraday. [Edited to add: a version of my discussion of Faraday is now included in the Bookforum review as well.]

Michael Faraday, the experimental physicist who did pioneering work on electromagnetism in the early nineteenth century, walked the fine line between insider and outsider in a way that is nearly impossible to do today. Faraday grew up poor and began his scientific career as a bottle washer in a laboratory in London’s Royal Institution. Like Carter, he had no university education and puzzled through the mysteries of the universe largely on his own. Unlike Carter, he was eventually regarded as a genius and recognized as one of the greatest experimental scientists of all time. In fact, it was Faraday who first developed field theory after sprinkling iron filings near a magnet and observing the predictable patterns they formed. “Ironically,” Wertheim writes of Carter, “the one major figure in the history of physics whose life story in some respects paralleled his own had been the source of an idea he could not stomach.”

Faraday lived at a time when the boundaries between amateur experimentalist and professional scientist weren’t quite as rigid as they are today, but he, too, felt the sting of being ignored by the academy. It wasn’t until the more respected physicist James Clerk Maxwell turned the results of Faraday’s experiments into differential equations that the physics community embraced field theory, setting the stage for the industrial revolution, the telecommunications industry, home electricity, and quantum mechanics. Ironically, Faraday’s lack of a formal education meant that he couldn’t understand Maxwell’s equations; Wertheim tells us that he “died a hero, but an alien in the world he had helped create,” and it’s easy to imagine him sympathizing with Carter and the other outsider physicists who still feel left out of that world today.

Saying Goodbye to the Tevatron

Welcome to what I hope will be an occasional series: Labs of the Past, in which I take a look at labs or pieces thereof that no longer exist. Last fall, Fermilab shut down its flagship accelerator, the Tevatron, which had spent decades reigning as the most powerful particle accelerator in the world. Fermilab is still going strong and is throwing its considerable weight behind an innovative intensity frontier program, but I wasn’t the only one who was sad to see the Tevatron go. Needless to say, I was delighted to hear this week that data from the CDF and DZero collaborations is still actively contributing to the hunt for the Higgs boson. And in case you need to brush up on the accelerator’s many other achievements, the latest print issue of Symmetry Magazine includes a lovely piece on the Tevatron’s legacy by Rhianna Wisniewski.

I got my start writing about physics as a Fermilab intern, so when it was time for the Tevatron to be laid to rest last fall, I felt like I had to be there to say goodbye. What follows is my account of attending the Tevatron’s funeral on Septemeber 30, 2011.

Approximately seven hours after the Tevatron shutdown, I squeezed out of Fermilab’s Users’ Center bar to head to an Irish wake for what was, until just a few months ago, the most powerful particle accelerator in the world. This being the CDF party, The Drug Sniffing Dogs, the collaboration’s official rock band, had been going strong for three and half hours and showed no sign of stopping. The set list had devolved from what the lead singer called “crying in your beer songs” like “It’s the End of the World as We Know It (And I Feel Fine)” to dance party favorites like “Super Freak.” I had signed two commemorative T-shirts, one on someone’s body, while sipping Two Brothers’ Atom Smasher beer and munching on homemade cookies frosted with the CDF logo. The whole affair was tinged with the melancholy elation of the night after high school graduation, with everyone desperately savoring the last moments of an already bygone era before truly letting themselves move on to what they hoped would be bigger and better things.

For many physicists, those bigger and better things await them at CERN’s Large Hadron Collider, which is already colliding particles at over three times the energy of the Tevatron and only operating at half power. Others will be staying at Fermilab to work on the lab’s new intensity frontier program, which involves building state-of-the-art superconducting accelerators to study muons and those potentially faster-than-light neutrinos you’ve heard so much about. Still others are moving on to careers in industry or medicine, while some are retiring along with the Tevatron. But on Friday, all eyes were on the machine that had, for the last 28 years, led the way in the study of the fundamental building blocks of our universe and made the Illinois prairie the best place in the world to be a high energy physicist.

The SoundLab, Arup

If you are a cool person who knows about architecture and design, you probably know all about Arup. As for me, I only recently heard about what is easily the world’s hippest engineering consultancy. But even I was already unwittingly familiar with Arup’s work, as it is behind several of the most iconic structures built for the Beijing Olympics, the new Lincoln Center, the Seattle Central Library, a few particle accelerators, and even the latest skyscraper being built down the street from my old apartment in Mexico City—just to name a few of its many projects.

Less tangible but no less impressive is the work of Arup Acoustics, which, broadly speaking, helps clients build spaces that are conducive to listening to certain sounds and not others. Despite its impressive list of projects ranging from wind farms to opera houses, the crowning achievement of Arup Acoustics may be eight sparse rooms scattered across the world: the SoundLabs.
