Bill Bardeen, renowned quantum field theorist, retires

From quantum chromodynamics to family genealogy, Bill Bardeen loves to solve puzzles.

As a theoretical physicist, his approach to solving physics problems about the fundamental nature of matter made him a world-leading expert on quantum field theory. In his spare time, as a genealogist, the same persistence resulted in tracing the Bardeen family line back to Massachusetts in 1717.

In December, after 35 years of tackling theoretical physics problems at Fermilab, Bardeen retired. There is little doubt, however, that he will continue to be fascinated by puzzles.

“I have to get really into a problem,” Bardeen said. “I strive to understand things as deeply as I can.”

Bardeen joined Fermilab’s theory group in 1975 on the invitation of Ben Lee, a Fermilab pioneer who chaired the group from 1973 until his tragic death in 1977. Bardeen was working as a professor in Stanford University's physics department, but the opportunity to collaborate with Lee, whom he had worked with as a post-doc at Stony Brook University in the '60s, made the decision easy, at least for him.

Bardeen’s wife, Marge Bardeen, who heads Fermilab’s Education Office, and his two children, were not as keen to leave sunny California behind, he recalled.

“The vote was three to one, but the tally got overwhelmed by one vote in particular,” Bardeen said. “I felt that I could do my best physics here.”

There was no denying that the Bardeens were Midwesterners at heart. Bill Bardeen was born in Pennsylvania and moved to Champaign, Illinois when he was nine. He met Marge in a chemistry class during his senior year of high school, but they didn’t start dating until they were both students at Cornell University. They married his junior year of college and went on to have two children, Chuck and Karen.

Bardeen is best known for his work on quantum field theory anomalies, which play a fundamental role in defining the Standard Model of particle physics. He received the J.J. Sakurai Prize of the American Physics Society in 1996 for his work on quantum chromodynamics. In 1984, he became a Fellow of the American Physical Society and was elected to the American Academy of Arts and Sciences in 1998, the National Academy of Sciences in 1999 and as a fellow of the American Association for the Advancement of Science in 2008. He chaired Fermilab’s theory group from 1985 to 1992, spent a year as the head of theory group at the Superconducting Super Collider, and then returned to Fermilab when the project was canceled in 1993.

In Brief

Dark Energy Camera on WTTW tonight at 7 p.m.

Chicago Tonight will highlight the Dark Energy Survey and construction of the Dark Energy Camera at Fermilab on its Scientific Chicago segement at 7 p.m. tonight on Channel 11 WTTW. The monthly science segment highlights remarkable stories of scientific and technological advances being made right here in Chicago. If you miss the episode, you can view it later on the show's website.

Scientific Chicago featured Fermilab's hunt for the Higgs particle in its Oct. 19, 2010, episode. You can view that episode here

IceCube opens up a window on energy in the universe

From Washington Post, Feb. 7, 2011

The world's newest astronomical observatory is defined by a field of 86 colored flags rippling across an ice-covered polar landscape. Each banner marks a line of glass-covered orbs that stretches down a mile and a half into the ice, like beads on a frozen string.

Known as IceCube, this massive underground array is designed to do what no other observatory has done before - catch a glimpse of elusive neutrinos, ghostly particles that are formed in the hearts of supernovas, black holes and other deep-space objects and may give scientists new information about the origins of the universe.

"The idea with IceCube is to do astronomy, but instead of using light, we're using neutrinos," said Greg Sullivan, a physicist at the University of Maryland who is one of the collaborators on the $279 million project.

"It opens up a window on energy in the universe," he explained. "We've seen particles in outer space that are 10 million times more energetic than the ones we can accelerate on Earth. Neutrinos are a way to try and find out what's causing those very high energy [particles]. It's been a mystery for 100 years."

Students learn the wonders of science at Fermilab

From Trib Local, Feb. 5, 2011

When many of us think of Fermilab, we think of particle accelerators and bespectled physicists working on complex problems.

Fermilab is also one of Chicagoland's best-kept secrets for children's education programs.

From prekindergarten to graduate school, Fermilab's education office offers an array of classes and activities to encourage and strengthen an interest in science.

Students in fourth through sixth can become "Junior Prairie Rangers" after the completion of a series of activities and classes that focus on Fermilab's restored prairie and the natural habitat of local wildlife.

Other course offerings include using Legos to study engineering and learning about how the weather works- a good class after the recent blizzard.

Shared vision

ICFA writing group: Barbara Warmbein, DESY; Judy Jackson, Fermilab; Rika Takahashi, KEK; Pier Oddone, Fermilab; Sachio Komamiya, U of Tokyo; James Gillies, CERN; Joachim Mnich, DESY; and Tim Meyer, TRIUMF.

Last July, at the meeting of the International Committee of Future Accelerators that I missed because of my daughter’s wedding, I was elected to chair a committee to produce a document with a shared global vision for particle physics. The document should be easily accessible to policy makers, funding agencies and members of the public from all the world’s regions. It should demonstrate a high degree of coherence across the world’s programs, and place the regional programs in the context of the global program. Associated with the document there will be a website where those with a deeper interest and the time to indulge it will be able to explore the global program in much greater detail.

Last week our committee met at DESY together with writers from several laboratories. The meeting took place over two days in which we hammered out the messages we want to convey and drafted a rough design for the document. I will present our committee’s progress at the ICFA meeting next week in Beijing and will take direction from ICFA on the document’s further development. Communicating a shared vision has never been more important than today, when all the regions are traversing turbulent times.

After all the advances we have made, our lack of understanding of the basic laws that underlie our universe is dramatic. Profound questions that seem almost theological in nature both bedevil and inspire us. The answers to some and perhaps all of these questions appear to be just over the horizon as the world comes together to exploit the most powerful set of scientific tools ever assembled. Will we be rewarded with a grand synthesis that will resolve all these mysteries in a revolutionary new framework, as was the case in the past with quantum mechanics? Or will today’s answers lead the way to even more fundamental questions, opening vistas onto more distant horizons?

Particle physics has developed a remarkable culture of collaboration across many countries. Large detectors for colliders like the LHC and the Tevatron and other projects at the intensity frontier from B-factories to neutrino experiments bring together dozens of institutes across many countries. Within each collaboration physicists confront tough decisions on design and technology choices. Ultimately it is our shared and passionate vision that settles the hard-fought battles and brings everyone to work together toward a common purpose.

The document we will produce takes us beyond the shared vision for a single detector to the globally shared vision for the future of our field. Within that vision the facilities we develop in the different regions complement each other. Reaching a grand synthesis in physics or discovering the next set of mysteries will require a variety of approaches carried out in the various regions of the world. Accelerators that reach the highest energies and produce new particles directly, accelerators with the greatest number of particles to study the rare processes that carry the imprints of worlds beyond our direct reach, and major observatories of natural processes deep underground, on the surface of the Earth and in space can all take us beyond our present horizon. All will be needed if there is a grand synthesis ahead of us.
