IFT Colloquium

The first IFT Colloquium of the Spring 2007 series is scheduled for
Wednesday, February 14 at 4:05pm in 2165 NPB by Professor
Linda M. Bartoshuk, a Member of the National Academy of
Sciences. Linda will be speaking on 'Are you a supertaster? How
do we know? What does it mean? (Some Demonstrations)' Some
individuals (supertasters) are born with an unusually large number of
taste buds. Supertasters live in a neon food world compared to the
pastel food world of those with the fewest taste buds. The way foods
taste affects our preferences for them and thus our diets. This
affects risk factors for a variety of health problems (some cancers,
cardiovascular disease, alcohol intake, smoking). We will conduct a
test at the lecture to let you know if you are a supertaster. By the
way, comparing taste experiences across individuals or groups is
very difficult since we cannot share experiences directly. We will
discuss the way psychologists try to solve this problem.

Congratulations!

Larry Phelps, Senior Engineer, is to receive a Division Three 2006-
2007 Superior Accomplishment Award. Larry will receive a cash prize
and will be recognized at an awards ceremony in February. His
nomination will also move forward to be considered for a university-
wide award. Congratulations Larry!


CDF Continued from Page 1
By measuring the W-boson and top-quark masses with ever greater
precision, physicists can restrict the allowable mass range of the Higgs
boson, the missing keystone of the Standard Model.

"This new precision determination of the W boson mass by CDF is one
of the most challenging and most important measurements from the
Tevatron," said Associate Director for High Energy Physics at DOE's
Office of Science Dr. Robin Staffin. "Together, the W-boson and
top-quark masses allow us to triangulate the location of the elusive
Higgs boson." The CDF result is now the most precise single
measurement to date of the W boson mass. Combining the CDF result
with other measurements worldwide leads to an average value of the
W-boson mass of 80,398 +/- 25 MeV/c2.

Prior to the announcement of the CDF result, ALEPH, an experiment at
CERN, the European Center for Nuclear Research, held the record for
the most precise W mass measurement. ALEPH and its three sister
experiments at CERN, which operated until 2001, made significant
contributions to the measurement of the Ws mass. The experiments
relied on electron-positron collisions produced by the LEP collider at
CERN. In contrast, CDF experimenters are analyzing proton-antiproton
collisions produced by Fermilab's Tevatron, the world's most powerful
particle collider.

"Compared to the electron-positron collisions at LEP, the proton-
antiproton collisions at the Tevatron result in a 'dirty' environment
experimentally," said Jacobo Konigsberg, University of Florida
physicist and CDF cospokesperson. "Every collision produces
hundreds of particles along with the W boson that need to be properly
accounted for. That's why our analysis is so challenging."

STUDENT NEWS


The Society of Physics Students chapter has been recognized as an Outstanding SPS Chapter by the national
SPS organization. The selection is based on the depth and breadth of the SPS activities in areas such as physics
research, public science outreach, physics tutoring programs, hosting physics meetings, and providing social
events for members. Also recognized and congratulated are the SPS officers, and Yoon Lee, the SPS faculty
advisor. Adding his congratulations to the SPS student recognition was Professor James Dufty, who recently
submitted an NSF renewal proposal in which he mentions the success of the program.
The UF Society of Physics Students website is located at http://www.phys.ufl.edu/-sps/


The Annual
Alachua
Region
Science and
o Engineering
Fair
is February 13,
Graphic is of the Alachua and your help is
Region Science Fair Website needed. Would
http://tlc.sbac.edu/scifair/ you be willing to
serve as a judge
for the fair? There are over 260 projects in the
Fair this year. This is a dramatic increase
over last year and shows student's growing
enthusiasm for science. The time
commitment is from approximately 8:00am
until 3:00pm on February 13, 2007.

This year's fair will be held at Santa Fe
Community College. Judges are asked to
check in by 8:00 A.M. After a short
orientation, category judging will begin at
8:45am and end at 12:00 Noon. A working
lunch will follow before the state science fair
participants are selected in the afternoon.

Judges can register on-line at
http://tlc.sbac.edu/scifairl

If you have any questions or need any help,
please contact Mary Jean Anderson at
andersmj@sbac.edu

Deepak Kar, Physics
Student, won honorable
mention for his photo
(right) titled, "Time Stands
Still" in a photography con-
test organized by the UF
International Centre. The
photos can be viewed at

Post Doc Position Available

There is an opening for a postdoctoral researcher,
via a competitive, prestigious, named postdoctoral
fellowship program. In particular, someone to lead a
project that will use single-molecule transistors as a
tunable model system to study quantum phase
transitions. Related work would likely include extending
single-molecule transistor measurements to high
frequencies. A new experimental rig (a 12T variable
temp. probe system) has been ordered and will be
available for use, and there is ample theory support.

This opportunity comes about due to the recent
establishment of the W.M. Keck Program in Quantum
Materials (http://keckmaterials.rice.edu) at Rice. In
this program, there will be ample opportunities for
fruitful interactions with other investigators, all using
tunable model systems (either nanostructures or cold
atoms) to examine strong correlation physics.

Interested candidates should contact Professor Douglas
Natelson at natelson@rice.edu
