Iliana Bozhanova steps up Bulgarian dance at Fermilab

Iliana Bozhanova, renowned Bulgarian folk dance instructor

A renowned Bulgarian dance instructor will offer tips at Fermilab tonight during her only stop in the Chicagoland area.

As part of her U.S. tour, Iliana Bozhanova has agreed to teach a master class on Bulgarian folk dance at Fermilab’s Kuhn Village Barn from 7:30 p.m. to 10:30 p.m.

Bozhanova has worked as a choreographer for groups all across Europe and is currently a choreographer for the Ensemble Voivodintsi in Bulgaria.

Bulgarian dancing is one of the favorite styles practiced by Fermilab’s International Folk Dance Group because it doesn't require partners and offers a choice of musical rhythms.

“Bulgaria is at a crossroads. There are a lot of interesting rhythms in that part of the world, and within Bulgaria, from challenging and aggressive music in the North to the more melodic style in the South,” said PPD’s Doug Jensen, who has participated in the international folk group since it started more than 20 years ago.

Many Bulgarian dances are line dances where people cross their arms in a ‘W’ across their chest, or in a low ‘V’ in front of them. Footwork is characterized as very quick and heavy or slow and “cat-like”.

Mady Newfield, who runs Fermilab’s International Folk Dance Group, invited Bozhanova to come to Fermilab after meeting her at the annual Folk Ball in Madison, Wis., a few years ago. Tonight’s class is free but suggested donations are $8 for adults and $4 for students. No pre-registration is required.

Bulgarian dancer Nina Kavardzikova will give another workshop on March 19.

Entertainment Tonight searches for angels and demons at CERN

From symmetrybreaking, Feb. 11, 2009

Entertainment Tonight offers you a chance to see inside the world's largest science experiment mentioned in the upcoming movie Angels and Demons.

The prime-time television show broadcasts live Thursday and Friday, Feb. 12-13, from CERN, the European laboratory for particle physics research on the border of France and Switzerland.

CERN serves as one of the settings for the Angels and Demons movie to be
released by Sony Pictures in May.  The movie is based on the  best-selling novel by Dan Brown, which explores the boundary between science and religion through an action-packed mystery.

Angels and Demons focuses on a plot to destroy the Vatican using a small amount of antimatter. In the book, that antimatter gets stolen from CERN and the heroine is a CERN scientist. 

It is unclear how closely the movie will follow the book. In past interviews, Dan Brown has discussed the role CERN played in his book. CERN has posted a Q&A section on its Web site to clarify the distinctions between the events in the book and real-life science at CERN.

The movie stars Tom Hanks and is directed by Ron Howard.

You can see a trailer of the movie here.

Use stimulus to expand scientific research funding

From Houston Chronicle, Feb. 10, 2009

A key question being debated in Congress is, "How much emphasis should we place on immediate economic stimulus vs. long-term growth?" One investment that satisfies both requirements is the proposed expansion of funds for scientific research supported by the National Institutes of Health (NIH), of particular benefit to the Texas Medical Center, the National Science Foundation (NSF), which supports all of Texas' research universities, NASA and other agencies.

Investments in scientific research, development and education give the greatest "bang for the buck," both in their ability to immediately energize the economy and in their long-term benefits.

Every dollar going into a research grant has a multiplier effect as it supports education, small business and human innovation. Studies show increased economic activity, including wages paid, of at least $2.5 for each dollar invested in NSF, resulting in higher tax revenues for state and federal governments.

Scientific research funds support education by training students and postdoctoral fellows in all 50 states, who in turn recirculate their stipend dollars. Small American companies benefit as they receive orders for specialized high tech equipment - indeed many startup companies depend on such purchases in their early phases - and these dollars also get circulated back into the economy.

Fermilab Result of the Week

Single top, on the road to the Higgs!

Multivariate techniques are developed to separate the events due to detection artifacts (left) from single top events. At the right of the plot, an excess of single top events (orange & red) appears over the remaining backgrounds.

Experimentalists are captivated by the hunt for rare particles.

After a long quest, scientists at Fermilab discovered the top quark in 1995 in events where it was produced in pairs. Fourteen years later, scientists have firmly established the existence of its companion process, the production of top quarks one at a time.

Single top production, an important Standard Model measurement, shares the same detector signature as another long-sought particle, the Higgs boson. Single top events are only a few times more likely to occur than Higgs boson events, so measuring single top is an important step toward the Higgs.

Single top quarks are produced at a rate of about one in 10 billion of all collisions at the Tevatron. Isolating the top quark’s signal from background signals is a key step in measuring its properties. This enormous background can be reduced in proton-antiproton collisions by requiring more leptons in the data. Because of the reduction in backgrounds, events with a lepton, jets and neutrino-caused energy imbalance have been the best place to look for single top quarks.

For the first time, in order to study more events with single top quarks, a group of CDF scientists looked for the single top in events with jets, missing energy and no leptons. To isolate a sample of candidate events, they had to understand the giant background contributions to an unprecedented level. The group found a more than two standard deviation excess of events over the expected background. Their independent measurement of the key properties of these events will add precision to a combined result with the lepton-based single top searches.

The techniques used in CDF will help pave the way to the main challenge that scientists at CDF hope to conquer: the discovery of the Higgs boson.
