"In Visible"—an artist's perspective of the universe

"Calculations" is one of more than 20 works by Adam Fung hanging in the Fermilab Art Gallery until Jan. 20.

One night when artist Adam Fung was hiking among the red terrain in Utah, he looked up and saw the night sky untainted by city lights. The bright band of the Milky Way galaxy, the colorful stars too many to count and all the darkness in between gave Fung a new inspiration for his work.

Fung has spent most of his career capturing different landscapes around the world, including icebergs in Antarctica and snow-capped volcanoes along the western United States coast. However, for the past few years he has changed his focus from Earth to outer space and the mysteries of the universe.

Fermilab's Art Gallery will host some of Fung's newest space-related art from Nov. 12 through Jan. 20 on the second-floor crossover in Wilson Hall. The exhibit, "In Visible," will feature a number of drawings and paintings that Fung hopes will build a connection between art and science for the audience.

Many of Fung's works feature geometric shapes over a starry background. Fung gets his ideas for the backgrounds looking at images on NASA's website, and for the foregrounds he draws on his own beliefs of how art should represent the many dimensions scientists study.

"When I started thinking about the universe it didn't make sense to me that we would map that in just one quadrant or square," Fung said. "So, I started making other geometric forms, and those forms become layered on each other in my work."

The mysterious dark matter that permeates the universe was a particular inspiration for Fung.

"I began researching dark matter," Fung said. "It's this unseen component that's a vital part of our universe, and I saw a parallel in the actual work I do during the process of making an image."

Fung's work contains textures and patterns that are, at first, indistinguishable from one another. However, upon closer inspection, the viewer can see the various layers Fung used to bring everything together. Fung sees dark matter similarly: It's invisible to anyone simply looking at the sky, yet it is believed to be prevalent throughout the universe.

An artist reception will take place on Friday, Nov. 16, from 5 to 7 p.m. For further information about Adam Fung and his art, visit his website.

Passing along LHC know-how to future generations

Preserving expertise about how complicated detectors work is one of the Large Hadron Collider's biggest challenges. Photo: CERN

The Large Hadron Collider is the product of generations of work. As time presses on, many LHC collaborators involved from the beginning have moved on to other projects, and memories of the decade of construction that produced the largest collider yet, along with its associated detectors, have begun to dim.

This has implications for the LHC experiments, which are meant to run for years to come.

The importance of passing along knowledge to newer collaboration members is already apparent with a major work period planned to take place during the long shutdown next year.

"Everybody is a bit rusty," CMS technical coordinator Austin Ball says. "After nine years of [building CMS], everybody who had been there through the whole process, they knew they were good. Now we've had three years to forget all of that. We're going to have to start slowly and make sure we don't put too much load into the schedule."

Beyond the shutdown, the lifetime of the LHC is now expected to be more than 30 years. Alongside engineering and physics, preserving expertise will be one of the biggest challenges at CERN.

Political science: physicist Bill Foster heads back to Congress

From Science, Nov. 14, 2012

You can't question Bill Foster's determination. After losing his seat in the House of Representatives two years ago, the Illinois Democrat snagged a different one as he trounced seven-term House veteran Judy Biggert (R-IL) in the contest to represent the state's newly drawn 11th district. An independently wealthy businessman and a particle physicist by training, Foster worked at Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, for 22 years before leaving in 2006. When he takes office in January, he will be one of two Ph.D. physicists in Congress. [The other will be Representative Rush Holt (D-NJ), a plasma physicist who will return for his eighth term in the House.]

Measuring the Higgs-like boson at the Tevatron

The latest combined results from CDF and DZero test whether the newly observed particle measures up to the expectations of a Standard Model Higgs boson.

If the new particle discovered in July is the long-sought Higgs boson, then it should measure up like one when compared to the predictions of the Standard Model. The Higgs boson plays an important role in the Standard Model, giving mass to the quarks, charged leptons and weak-force carriers, but the Standard Model version of the Higgs boson is not the only possible way to explain why those particles are massive. Many exotic theories exist beyond the Standard Model that predict one or more versions of a Higgs boson that would behave differently from Standard Model expectations. The latest combination of CDF and DZero results seeks to measure the behavior of the newly observed boson to help determine whether it could be the Standard Model Higgs boson or is possibly something more exotic.

The Higgs boson can be produced in many ways during a proton-antiproton collision, and once one is made it can decay in many ways as well. Exotic models might turn off certain production and decay modes while enhancing others. Measuring the Higgs boson production rate in each independent decay channel allows the predictions of the Standard Model and these exotic models to be tested. At the Tevatron, the rates for Higgs boson decays to W boson pairs, tau lepton pairs and bottom quark pairs were all consistent with the Standard Model. More photon pairs were observed in the combined search than were predicted by the Standard Model by a slight margin, but not enough to be incompatible with it.

The combined analysis goes a step further by simultaneously examining the new boson's particle characteristics during production and decay. Many analysis channels contain a mixture of processes, perhaps with quarks being involved in producing a Higgs boson and W bosons involved in its decay. Tracking all of these possible combinations individually allows the CDF and DZero collaborations to constrain the fundamental preferences the new boson has between bosons and other particles. These results are all consistent with the Standard Model prediction for a Higgs boson.

Mike Cooke

The CDF and DZero detectors have served their collaborations well for decades, taking data that have led to historic discoveries and significantly improved our understanding of the universe at the most fundamental level. Both detectors are now available as exhibits for tour groups at Fermilab.

Making the case for science: Representative Randy Hultgren sees room for improvement in federal role

From Science, Nov. 13, 2012

Representative Randy Hultgren (R-IL) came to Washington in 2011 after defeating Bill Foster, one of the few Ph.D. scientists in Congress. (Foster will return to Congress in January after defeating Representative Judy Biggert (R-IL) in a different district.) Although Hultgren, a lawyer and former Illinois state legislator, lacks any background in science, he joined the U.S. House of Representative's Committee on Science, Space, and Technology and quickly made a name for himself as an advocate of basic research.
