Handle holiday stress with Recreation Office offerings

ILC Communicator for the Americas Elizabeth Clements practices yoga at her desk during lunch. Clements participates in the Recreation Office sponsored hatha yoga class on Tuesdays.

As Christmas music fills the air and holiday shopping, cooking and family gatherings fill every moment of spare time, the stress and pressure of the holiday season sets in. But now, imagine a quiet, gentle ocean. Concentrate on your breath. Reach skyward and then fold forward. Doesn't that feel better?

Exercise is one of the best ways to relieve holiday stress and, according to Recreation Office Manager Jean Guyer, there are plenty of ways for employees and users tocenter their bodies and minds. The Recreation Office offers back-to-back classes, including yoga, strength training and Kyuki-Do, through the holiday season and beyond.

Christopher Baxter teaches Fermilab's Hatha Yoga classes on Tuesdays from noon to 1 p.m. in Ramsey Auditorium. "The class allows employees to take an hour out of their work day and benefit from yoga," he said. "Some participants say it feels like taking a nap or having a whole body massage. It allows you to relax before going back to work."

People can also sign up for six-week sessions of muscle toning classes, which meet Tuesday and Thursday evenings or Kyuki-Do, a Korean style of martial arts, which meets on Monday and Wednesday.

Those interested in other forms of exercise should stay on the look out for more offerings this season. "In the past, we have also offered self-defense classes and a dance program, including country line dancing and ballroom dancing classes," said Guyer.

For a less structured work out, employees and users can join the recreation facility. "There's no reason that people shouldn't find a way to have fun, exercise and relieve stress at this time of year," said Guyer.

More information and registration for all classes and the Recreation Facility is available in the Recreation Office on the 15th floor of Wilson Hall.

The Unexplained: The God of small things - How the universe holds together

From San Francisco Sentinel, Nov. 16, 2007

40 years ago, an unknown physicist in Edinburgh, Scotland, came up with a theory of how the universe holds together - sparking a multibillion dollar race to find the key particle. Is the most sought after prize in modern physics about to be won at last?

Amid 800 acres of landscaped grounds a mile from Princeton, New Jersey, stands the Institute for Advanced Study, one of the world's most prestigious centers of scientific thought. Within this intellectual microcosm, many of the most accomplished physicists in history, from Oppenheimer to Einstein, have wrestled with the deepest puzzles of the universe. To be invited to talk at Einstein's former lab remains among the highest honors a scientist can receive. And it was with this terrifying thought in mind that in March 1966 Peter Higgs, a 36-year-old physicist from Edinburgh University, loaded up his car and headed up the freeway.

Tucked into Higgs's luggage was the reason he had been invited. The notes for his highly contentious lecture overturned some of the most deeply-held beliefs of the resident experts. They proposed something remarkable, that an invisible field, which stretches throughout the entire universe, holds the key to one of the greatest mysteries of modern science - the nature of matter and mass.

Shadow World

From Science News Online,
week of Nov. 17, 2007

How many dimensions space has could all be a matter of perspective

In a school of thought that teaches the existence of extra dimensions, Juan Maldacena may at first sound a little out of place. String theory is physicists' still-tentative strategy for reconciling Einstein's theory of gravitation with quantum physics. Its premise is that the subatomic particles that roam our three-dimensional world are really infinitesimally thin strings vibrating in nine dimensions. According to Maldacena, however, the key to understanding string theory is not to add more dimensions but to cut their number down.

In his vision, the mathematical machinery of strings completely translates into a more ordinary quantum theory of particles, but one whose particles would live in a universe without gravity. Gravity would be replaced by forces similar to the nuclear forces that prevailed in the universe's first instants. And this would be a universe with fewer dimensions than the realm inhabited by strings.

Director's Corner

28 and Counting

Hesheng Chen, Director of the Institute for High Energy Physics, and Fermilab Director Pier Oddone shake hands after signing a MOU.

During the last two days we have been privileged to host the 28th meeting of the U.S./China Joint Committee on High Energy Physics. The protocol for this committee falls under the comprehensive U.S. - China Agreement on Cooperation in Science and Technology signed by President Jimmy Carter and Premier Deng Xiaoping in 1979. Pief Panofsky, T.D. Lee and Bob Wilson played important roles in opening scientific cooperation between the U.S. and China -- one of the earliest cooperative ventures between our two nations following the Cultural Revolution. I started participating in the Joint Committee 21 years ago when I was Physics Division Director at LBNL. I have seen over the years not only the tremendous economic growth that has transformed China, but also the remarkable development of the country's accelerator-based science.

Today the tau-charm factory is being commissioned in Beijing at the Institute for High Energy Physics, the Shanghai Synchrotron Radiation Facility is under construction with a magnificent new building in the Pudong area of Shanghai and construction of the China Spallation Neutron Source is about to start in Guangdong in Southern China. These three facilities are state-of-the art, world-class facilities. Cooperation between the U.S. and China began in the area of particle physics but is now more pervasive as laboratories both in the U.S. and in China build accelerator-based facilities for other sciences. There is also a very important non-accelerator experiment, the Daya Bay experiment, initiated by LBNL and IHEP and today the world's most ambitious reactor-based neutrino experiment.

During the meeting, Hesheng Chen, Director of IHEP, and I, signed a memorandum of understanding between IHEP and Fermilab on the development of SCRF technology. This follows a recent MOU that Fermilab signed with Peking University. Our collaboration in R&D will hopefully lead to joint US - China projects to build new accelerators based on SCRF technology.

Members of the U.S./China Joint Committee on High Energy Physics meet as part of the committee's 28th meeting, held at Fermilab this week.

This outage will affect central web services and FNALU.

"Water to the Ropes" showing
at noon Wednesday

In honor of the 40th anniversary of Fermilab, there will be a showing of "Water on the Ropes: The evolution of an accelerator" at noon on Wednesday in One West.The film is 30 minutes long. It was made to commemorate the 20-year anniversary of Fermilab on Dec 2, 1988. Brief interviews with Robert Wilson and Leon Lederman are shown as well as early construction footage. This program was produced by Visual Media Services.
