Welcome back to the fourth edition of Florida Physics News. Inside you'll
find news about our students, faculty, staff, and alumni, as well as feature
articles on our research, teaching, and outreach. As always, we hope that you'll
write to let us know about your whereabouts, achievements, and careers.

I J In reflecting on department events over the past year, I was struck by the
number of anniversaries that have recently passed or that are fast approaching.
For instance, 2005 was the 100th anniversary of Albert Einstein's "Miraculous Year",
during which he published revolutionary papers on the quantum theory of light, the
theory of relativity, and Brownian motion. It was also the 75th anniversary of the
UF Department of Physics' founding. We have come a long way-from modest
Alan Dorsey beginnings as an outgrowth of the College of Engineering, we now have nationally and
P r ad C r internationally visible research and teaching programs. Our department is notable in
Professor and Chair
the diversity of our research-from condensed matter physics to high energy physics,
our faculty and students are at the forefront of physics. We are part of the operating
consortium for the National High Magnetic Field Laboratory, part of the Laser Interferometric Gravitational Wave
Observatory (LIGO) science collaboration, and we will soon have faculty conducting experiments at the Large
Hadron Collider in Geneva, Switzerland. Another department anniversary is approaching-2008 will mark the
tenth year that we've been in the New Physics Building. The building is a continuing source of pride to all of us,
and has been important to the department's growth over the past decade. We now have a robust and growing
program, with 50 Professors, 150 undergraduate physics majors, and 130 graduate students. As you'll read
inside, our faculty and students continue to garner awards and recognition.

We'll mark two important 50th anniversaries in 2007-the publication of the microscopic theory of super-
conductivity, and the Soviet launch of the Sputnik satellite. In 1957 John Bardeen, Leon Cooper, and Robert
Schrieffer wove the threads of several ideas into a grand theoretical tapestry that explained the remarkable
property of superconductivity-the ability of certain materials to carry current without dissipation at low
temperatures. A calculational tour de force, this paper had a profound impact on theoretical physics. For
instance, extensions of the theory predicted the Josephson effect in superconducting tunnel junctions
(Josephson 1964) and the pairing theory of atomic nuclei (Bohr and Mottelson 1958); it also serves as a
model for dynamical symmetry breaking in field theories. The American Physical Society, as well as several
other organizations will commemorate this anniversary with a series of symposia and conferences
throughout the year. Inside you will find an interesting account of UF superconductivity research, both
experimental and applied.

On October 4, 1957, a beeping, basketball-sized satellite drifted across the sky and ushered in the space age.
Shock at the Soviet success in rocket technology led the U.S. to an unprecedented investment in science
and technology. In 1958 Congress signed into law the National Aeronautics and Space Act, creating
NASA, and passed the National Education Defense Act, bolstering support for science and mathematics
education. The country also invested in basic research-the budget of the nascent National Science
Foundation more than tripled, from $40 million in the 1958 fiscal year to $134 million in 1959. In
2006 President Bush announced the American Competitiveness Initiative, which proposes similarly
significant increases of federal funding for science education and research. If you believe that this
investment in our future is important, please contact your representatives in Congress. In my next
letter I hope that I'll have some happy news to report on this long-overdue legislation.

And finally, 2006 marked the 100th anniversary of Gator football. As we go press, there is still
the lingering elation on campus over the Gators' success as the 2006 National Champions
in football, a brilliant follow-on to the 2006 National Championship in men's basketball.
But I suspect that you've already heard about this.

Happy anniversaries,

It is now established from a variety of
observations that approximately 80% of
the matter in the universe is dark. Little is
known about this 'dark matter' except that it is not ordinary
baryonic matter, that it is weakly interacting (indeed, it has so far
revealed itself only through its gravitational effects) and that it is
cold, i.e. its primordial random velocities are small compared to
the velocities acquired when falling into galactic halos. Relic
neutrinos are weakly interacting but are hot. They move too fast
to be readily captured in the gravitational wells of galaxies. The
evidence points compellingly to cold dark matter, or CDM.

To identify what particle constitutes the cold dark matter is one
of the foremost questions in all of science today. It is a new
particle, not described by the present Standard Model of
elementary particles. The two leading CDM candidates are
axions and WIMPs. Axions were originally postulated to explain
why the strong interactions are invariant under the discrete
symmetries P and CP in spite of the fact that the Standard
Model as a whole violates those symmetries. It was later shown
that axions are cold dark matter if the axion mass is in the
micro-eV range. WIMP is an acronym for "weakly interacting
massive particle". There are several examples of WIMPs in
extensions of the Standard Model, in particular in
supersymmetric versions of the Standard Model and in models
with extra dimensions. Faculty of the UF Physics Department
are involved in experiments to search for each of these
candidates: CDMS for
WIMPs and ADMX for
axions. Both experiments
are the most sensitive of their
kind in the world today.
ADMX (Axion Dark Matter
Experiment) is a
collaboration of scientists
from the University of Florida,
Lawrence Livermore
National Laboratory (LLNL),
UC Berkeley, University of
Washington in Seattle, and
the National Radio
Astronomy Laboratory in
Charlottesville, VA.

is a scaled up version of a detector that was located and took
data in the basement of Williamson Hall.

It has achieved sufficient sensitivity to detect dark matter axions
at the local galactic halo density (approx. 0.5 GeV/cc) in the more
favorable particle physics models. It is presently undergoing an
upgrade that will make it sensitive to dark matter axions even in
the least favorable particle physics models and at a fraction of
the halo density. The improvement is achieved by replacing the
high electron mobility transistors (HEMTs), which have so far
been used as front-end amplifiers in the microwave photon
detection chain, by SQUIDs. The SQUIDs were specially
developed by J. Clarke
and collaborators at UC
Berkeley for use in dark
matter axion searches.

The CDMS experiment aims to detect
WIMP Dark Matter by measuring the recoil
energy imparted to detector nuclei through
WIMP-nucleon collisions. One centimeter
thick, three inch diameter crystals of Si and
Ge are used as the
target for interacting
with the WIMPs.

When such an interaction occurs a
small amount of energy, 1 keV
(equivalent to a mass of 1 kg falling
from a distance 1 atom high), is
deposited in the crystals. The
crystals are cooled to within a few
tens of mK from absolute zero in

detect the small energy depositions The entire experiment is opera

however, goes beyond just measuring
the energy of an interacting WIMP. In fact, such events are
extremely rare, with only a handful of events expected within a year
of running, whereas background interactions from naturally
radioactive isotopes results in thousands of events per day in the
detectors. The CDMS experiment is able to identify and reject
background events by

"BCS@50": Marking the Discovery

of the Theory of Superconductivity

contributed by Peter Hirschfeld and David Tanner

The New Year 2007 will mark the fiftieth
anniversary of the invention of the
electron pairing theory of
superconductivity, one of the most
mysterious of all quantum phenomena.
It combines the flow of electricity without resistance with a near
perfect ability to screen out external magnetic fields, and offers
society the prospect of power transmission with minimal loss and
other applications based on large dissipationless magnets.
Superconductivity was discovered in mercury by H. Kammerlingh
Onnes in 1911, and was immediately recognized as one of the
most important problems in physics. Some of the greatest
theorists of the early and mid-20th century, including Pauli,
Feynman, and Landau attempted to unlock the secret without
succeeding. In 1957 John Bardeen, co-inventor of the transistor,
Leon Cooper, and Bardeen's graduate student J.R. Schrieffer
(BCS) came up with a key new concept. They postulated that
the ground state of a superconductor is made up of phase-
coherent pairs of electrons attracted by a force that overcomes
their natural repulsion. The existence of this state leads to a
variety of fascinating quantum phenomena, from lossless current
flow in wires, to the ability to tunnel effortlessly through barriers,
to converting electrons into holes upon reflection from a metallic

These are referred to as macroscopic quantum phenomena-
inherently quantum effects creating behavior that is easily visible
on the human scale. The BCS paper was published in the
Physical Review in 1957 and was almost immediately recognized
as the solution to the problem. It is the 5th most cited paper of all
time in that journal, and might possibly be number one were it
not for the fact that "BCS" theory is so well-known that it no
longer requires a citation.

The subsequent thirty years led to extensive explorations of the
consequences of the theory, but the field was considered

something of a backwater by 1986, when Bednorz and Mueller
discovered a new class of materials, the cuprate high-
temperature superconductors. The existence of such high
critical temperatures raised the possibility of room-temperature
superconductivity, with promises of a revolution in the generation
and transmission of energy, and did not seem to be allowed
within the usual BCS theory. The problem of high-temperature
superconductivity has now acquired the nearly mythic status that
the original problem of superconductivity once enjoyed.

To understand the importance and difficulty of the
superconductivity problem as perceived by the physics
community, one can look at the number of Nobel prizes awarded
over the years. The BCS work was awarded the Nobel Prize in
1972. Other superconductivity Nobels have gone to
Kammerlingh Onnes, Giaever, Josephson, Bednorz/Mueller,
Abrikosov, and Ginsburg, also to Osheroff, Richardson, Lee, and
Leggett for the related phenomenon of superfluidity in 3He. It is
widely believed that there is one more prize waiting for the
person who discovers the solution to the "high-Tc" puzzle.
Superconductivity research at UF is continuing in the laboratories
of B. Andraka, A. Biswas, S. Hill, A. Hebard, Y. Lee, G. Stewart,
D. Reitze, and D. Tanner, and in theoretical groups of A. Dorsey,
P. Hirschfeld, and P. Kumar. The following paragraphs give brief
descriptions of this research.

In Andraka's group, transport and thermodynamic techniques are
used to study the novel superconductivity of f-electron metallic
compounds and low-dimensional organic conductors at
temperatures down to 50 mK and in magnetic fields up to 45 T.

Of particular focus at the moment are filled skuterrudites
containing praseodymium. These materials are strong
contenders for novel superconducting pairing mechanisms,
which includes quadrupolar and spin fluctuations interactions.
Single-crystalline samples obtained by flux-growth techniques or
arc-melting are also investigated by other research groups.
The high-field thermodynamic measurements are done in
collaboration with Professor Takano's group.

In Professor Biswas' group, point contact spectroscopy in
magnetic fields of -30 T is used to study the so-called "electron-
doped" superconductors. His research focuses on the formation
of the "pseudogap" in underdoped materials and in determining
its origin. The pseudogap is a striking feature in the normal state
of these materials, and the way in which this pseudogap evolves
below the superconducting transition can give a hint towards the
underlying mechanism of the superconductors.

Professor Hill's group uses electron spin resonance techniques
at millimeter-wave frequencies to probe the properties of
low-dimensional organic conductors and superconductors. These
materials are formed from small molecules but have highly
anisotropic electronic structure and transition temperatures up to
15 K. The millimeter-wave spectroscopy provides details about
the Fermi surface of these metals.

Research in the laboratory of Professor Hebard is focused on the
fabrication and characterization of thin-film structures and is
based on the recognition that unusual physical phenomena occur
in restricted dimensions. Systems under study include metals,
composites, semiconductors, dielectrics, superconductors,
complex oxides and carbon-sixty molecular monolayers.
Characterization techniques available in the laboratory include
tunneling, dielectric spectroscopy, atomic force microscopy,
electrostatic force microscopy, ellipsometry, and electrical
transport at high fields and over a broad temperature
range. Previous work at AT&T Bell Laboratories by Professor
Hebard on superconductivity in the fullerenes (K3C6o) and the
superconductor-insulator transition is presently being extended
to new thin-film systems.

Professor Lee's group studies low temperature properties of
various materials. Its recent focus is on understanding the
nature of pure and disordered superfluid 3He using nuclear
magnetic resonance (NMR) and ultrasound techniques. Most of
the experiments are performed in extreme experimental
conditions, temperatures below 1 mK and magnetic fields up to
15 Tesla.

Professor Stewart is one of the leaders in the field of "heavy-
Fermion" superconductivity. The research interests of his group
include: highly correlated f-electron metallic compounds made in
his own laboratory involving either Ce or depleted U.

These are investigated using specific heat, susceptibility, and
resistivity down to 3He temperatures and in fields up to 16 T
(in-house) / 45 T (NHMFL Tallahassee) / 60 T (Los Alamos long
pulse NHMFL facility). Advances in the understanding

of the unusual magnetic and superconducting properties of
these materials is aided with the further help of active outside
collaborations with the Max Planck Institute in Dresden,
Germany, the University of Augsburg, Germany, the University
of Goettingen, Germany, and Oak Ridge National Laboratory.

Professor Reitze and Professor Tanner are members of
beamline U121R at Brookhaven's National Synchrotron Light
Source, where synchrotron radiation is to carry out pump-probe
far-infrared measurements of non-equilibrium effects in
superconductors and semiconductors, in collaboration also with
Larry Carr (NSLS) and Professor Stanton.

At UF, Professor |
Tanner's group
studies materials by
optical reflectance or
transmittance at
wavelengths from the
far infrared through the
near ultraviolet.
Among the topics
studied are
superconductors, low-
dimensional organic
superconductors, and
a number of other
systems. In studies of
the cuprate Minghan Chen aligns a spectrometer to study
superconductors, his high-Tc superconductivity in Professor Tanner's lab
students have been
able to measure the superfluid density across most of the high-
Tc family, and correlate this with the superconducting transition

Professors Dorsey, Hirschfeld, and Kumar, share a common
interest in the properties and pairing mechanism of the high-Tc
superconductors. Professor Dorsey studies fluctuation
phenomena, pattern formation in type-I superconductors, and
magnetic vortex lattices in these materials. Professor Hirschfeld
is currently interested in the effects of disorder and
inhomogeneity in these materials, and has an active
collaboration with Professor Cheng to study local properties of
superconductors with density functional theory. Professor Kumar
studies the phenomenology of unconventional electron paired
states, in particular thermodynamics and magnetic properties,
with additional emphasis on the heavy Fermion superconductors.

UF as well as physics professional societies like APS and ICAM
are planning activities to mark the fiftieth anniversary of the
publication of the theory under the heading "BCS@50".

postdoc based at
CERNto commission making final preparations for
the CSCL trigger what will be arguably the

most powerful scientific instrument ever
built. Its goal is to investigate the
properties of the tiniest building blocks of
nature known (and unknown) to man.
The Large Hadron Collider (LHC) at CERN will accelerate
beams of protons around a 27 KM ring, 100m under the Franco-
Swiss border before smashing them together at a center of
mass energy of 14TeV. The LHC may well change our
understanding of physics, possibly answering such diverse
questions as where does mass come from, why is there more
matter than antimatter and how do the four fundamental forces
of nature tie together.

The Compact Muon Solenoid
(CMS) is one of two general
purpose detectors being built to
record whatever comes out of the
proton collisions and University of
Florida scientists are in the thick of
it. CMS is a 12500 tonne, 21.5m

and layers of calorimeters to be
positioned entirely inside the coils whilst wrapped around the
outside are muon detectors. Having the magnet
in-between detector layers means that CMS makes use of the
magnetic flux both inside and outside the solenoid.

As well as taking leadership roles on the experiment in the
areas of grid computing, software, and physics, the University of
Florida led the design and construction of the endcap muon
detector system and built the first level trigger board. This
electronics board searches for muons in every LHC bunch
crossing (every 1/40millionth of a second) and sends a trigger to
the rest of CMS when it finds them. Over summer 2006 the UF
team worked in deepest darkest France alongside the
international collaboration of scientists charged with
commissioning CMS. A nominal part of each of the CMS
subdetectors, complete with full trigger electronics and readout
systems came together in order to run what was a real subset of
the CMS on cosmic muons. At the same time the magnet team
was commissioning the magnet.

The first phase of the tests ran during July and August during
which all four of the CMS subsystems took part in runs,
collecting 25 million cosmic events. The magnet was ran at
or above 3.8T for 15 million of them. Various subdetector
experts came together in a crack running team, meeting on a
daily basis to plan run activities and ensure constant 24/7
running of the detector. A data taking efficiency of better
than 90% was observed during which information was
streamed through the real CMS Data Acquisition electronics
and was distributed to Tier 1 computing centers. Online
event displays showed live unpacking of the events to
anyone interested and experts around the world were able to
run quality monitoring tools on the data the moment it came

During September, the tracker and the electromagnetic
calorimeter were removed and replaced by a magnetic field
mapper. October saw a second phase of running with just
the muon and hadronic calorimeter subsystems. The
magnetic field inside the barrel was mapped at various field
levels all the way up to the CMS 4T. 250 million cosmic
muon events were recorded allowing calibration, alignment
and detector efficiency studies.

Hardware allowing the barrel and endcap muon systems
to exchange trigger primitives with each other was
commissioned and the subdetectors ran under the
control of the global trigger. Important lessons were
learnt about the effects of the high magnetic field in the
hadronic calorimeter and the
barrel muon drift paths. There
was even a demonstration of a
calorimeter based trigger.

The 3rd International Workshop on Transition Edge Sensor Device
Physics (a.k.a. TES III), hosted by Professor Tarek Saab and the
Department of Physics, was held August 2006 at the New
Physics Building. The workshop's goal was to establish an informal
atmosphere to discuss the latest developments and challenges in
the field TES devices. The presentations given at the workshop
highlighted the fact that TES based detectors are rapidly becoming
the technology of choice in fields spanning sub-mm, optical, x-ray
astronomy, as well as gamma ray, neutrino and dark matter
detection. Downloadable pdfs of many of the presentations can be

About 140 physicists from 12 different countries gathered in
Gainesville to discuss and share their new results at the
International Conference on Ultra Low Temperature Physics
(ULT-2005). This event was held in the New Physics
Building of the University of Florida in August 2005 as one
of the satellite conferences following the International
Conference on Low Temperature Physics (LT-24).
Participants were greeted with a reception at the Florida
Museum of Natural History. More than 100 papers were
presented in 11 oral and 2 poster sessions and lively
discussions were exchanged in and out of the sessions.
The scientific program covered unusually broad research
areas in ultra low temperatures. Quantum phase
transitions, low temperature particle detectors, and quantum
devices were new topics presented during the conference
along with the traditional ULT topics such as superfluids,
quantum solids, and nuclear magnetism. In addition to the
regular program, there was a special discussion on
supersolids. Various theoretical ideas and details of recent
experimental results on this subject were discussed until
late in the evening. National High Magnetic Field Laboratory
was one of the major sponsors for this conference. ULT-
2002 was held in Kanazawa, Japan and the next ULT is
planned to be held in London in 2008 right after LT-25 in
Amsterdam, Netherlands.

The 46th Sanibel Symposium had a strong scientific program of sixteen plenary sessions
each with three invited talks. Sessions covered topics of high current interest such as
Molecular Electronics, Many-body Theory for Nuclear Motion, Few-body Relativistic Effects,
Radiation Damage in Bio-systems, and Metals in Biology. The meeting again was at the
King and Prince Hotel on St. Simons Island, Georgia, February 26 March 3, 2006. While
not on Sanibel Island (the Symposium left in 1977 and has not returned), the similarity of the
St. Simons beach-front location continued to be popular with participants. The number of
countries represented (22) was up from 2005, but the number of international participants
was down significantly. Most of that decrease stems from the increasingly difficult visa
process coupled with long-standing financial support limitations. Support from the Office of
Naval Research, IBM Corporation, University of Florida's Vice President for Research,
College of Liberal Arts and Sciences, and QTP's home departments (Chemistry and Physics)
was invaluable. Participant survey response continued to indicate satisfaction with the
scientific program. Responding to participant preference, the 2007 (47th) Symposium, will
have a new schedule, the first change since 2004. The meeting will begin on February 22
and end at noon on February 27. Detailed information on the program and arrangements
can be found at http://www.qtp.ufl.edu/sanibel.

Research Experiences for Undergraduates

Since 1999, the department has run a 10-week summer research
program for students who are contemplating a career in the
physical sciences. Supported by the National Science Foundation
and UF, the Research Experiences for Undergraduates (REU) .,
program serves fifteen undergraduates per year, drawn to
Gainesville from all over the country. Each participant carries out
original research under the careful guidance of a physics facultyI
member. The program also offers professional-development
workshops covering scientific communication skills and graduate
school applications, seminars on active areas of physics research,
and field trips to other scientific laboratories such as the National
High Magnetic Field Laboratory in Tallahassee. The summer ends
on a high note with a symposium at which each student presents
a talk on his/her project.

REU projects have spanned all research areas of the department,
ranging from ultra-low temperature measurements to analysis of
high-energy physics collider experiments. A significant fraction of
the projects have led to scientific publications co-authored by REU
participants. Where appropriate, REU students have also been
encouraged to present their results at regional or national
scientific meetings. I

Every year, REU participants have reported enjoying a positive
summer experience that reinforced their interest in a scientific
career. The great majority of participants have subsequently gone
on to graduate school in physics or a related field, thereby fulfilling ,
a major goal of the REU program.


Undergraduate who we are
Physics UP is a monthly undergraduate physics newsletter sponsored by
the University of Florida's chapter of the Society of Physics
Newsletter Students, for students, by students. We seek to strengthen the
undergraduate physics community at the University of Florida by
providing a forum for undergraduates to share their views and
experiences with each other and acting as a source of information
for opportunities and events in physics.


To welcome this years' new arrivals
to UF Physics, we thought we'd
compile small advicettes to help
them better find their way and
provide them with a cursory
perspective on the times ahead..
But first a brief introduction on who
we are. We are UP News! Some
twenty and four score physics
years (three college years) ago, a
girl named Cathy Yeh thought it
would be great to harvest the
undergraduate physics minds for
some funnies as well as stories of
physics experiences across the
nation each month. With the help of
the all-female troop that joined her,
UP News was born spitting out Star
Trek fanaticism, adventures on a
scooter, and other must-hear
stories. There's also news of SPS
(society of physics students) events
like "tea with a professor", and the
yearly picnic, along with happen-
ings in the department and physics
in general. It was and is the forum
for the quintessential physics
undergrad. Gotta have your UP

5 Tips to Surviving Physics
Classes: 1) Develop He-man like
biceps and pectoral muscles.
These will come in handy when you
try to open the 2-ton steel barri-
cades they call "doors" at the main
entrance, while carrying all your
stuff. 2) They purposely schedule
physics classes before the crack of
dawn so that only the most
motivated actually make it to class.

1 2 3

-a - - -

- --

Heed this: three or four hours of
sleep before other classes might
work, but not for physics classes! 3)
Make sure you're good at Frogger
before you try to cross Museum
Road and scurry into the Physics
building. In this high-traffic zone,
almost nobody watches where he
or she drives (and busses have
terrible deceleration). 4) Get
yourself acquainted with room
2229--a.k.a. the Physics Lounge.
This is where all the other lost
students go. At least you can be
lost together. 5) Don't be a
magnetic field. Ask questions often
and be prepared to DO WORK.

Another UP staffer wanted to point
out that any student of general
relativity knows that taking physics
classes is the mathematical
equivalent of physics classes taking
you. But, you can be a physics
major and keep up an ortho-normal
life. To counter the stress and the
strain of your classes, learn to
integrate with the flow, or just curl
up with a good B-field. If some of
this doesn't make sense now, it
surely will soon. With the help of
the wonderful professors here at
UF, enthusiasts in the Physics
Lounge (again, NPB 2229), and
SPS, you're on your way to a great
four years of your life.

Spring 2006

Vindication was ours! Every
spring SPS (Society of Physics
Students) hosts a picnic.
S Students, faculty and friends
and family are all invited to
enjoy food and lots of games
with the highlight of the afternoon being the
student vs. faculty softball game. I remember
going to my first picnic 2 years ago thinking, we
have good professors here at UF. Ergo, they must
be involved in their work and teaching and have
noooooooo time for exercise and sports. The
student-faculty softball game should be a joke with
the students coming out victorious. I have never
been more wrong in my college career! It was one
of several sad days for students as faculty not only
won, but also humiliated the student team. We
began to assign secret identities to our professors'
of characters like the Rock to soothe our pain. But
this year, whoo-wee! Students won 11-9! A
crowning achievement that pales the next scientific
marvel! Students were distracted by nothing.No
amount of bustling, no teasing, not even a low
flying airplane! That's right an airplane. Former
student Joe Gleason flew over the softball game in
his Champ doing stunts for the crowd of bystand-
ers. But the students held focus. Each had pigged
out on the various burgers, salads, chips and cook-
ies provided at the preceding barbecue. There's
always a ton of food, with leftovers sitting in the
lounge for frequenters to enjoy. Stomachs hitting
the floor and feet dragging, students trudged
behind the batting fence, and gave it their all. In
case you find yourself playing softball this spring,
and realize you're playing a losing game, think of
the Spring 2006 Vindication, and know that you too
have been vindicated. And to distract yourself later,
you've always got other games, more food, and I
wonder another low flying airplane?

Putting the 'Party'


A recap of the 2005 SPS Zone Meeting Mixer hosted by the UF chapter of SPS during the annual meeting of chapters from Zone 6 (Southeastern US)
November 11-12, 2005

By Cathy Yeh

Question: "What animal is the subject of
Schrodinger's famous paradox
concerning the measurement process of
quantum mechanics?"

The 5 people on the Landstander's team
answered "cat" without hesitation, while
the Yokish team howled at the easiness
of the question and waved their hands in
disbelief. Audience and contestants
were engrossed in the battle of physics
wits. The group trivia round ended with
the Landstanders a few points in the
lead. Next, each team selected a
representative to answer a series of 10
questions in 2 minutes. The 10
questions for the individual round were
contributed by Dr. Louis Bloomfield,
author of How Things Work: the Physics
of Everyday Life. Earlier in the day, he
had stopped by the SESAPS registration
counter at the Hilton where Justin Cohen
and I were desperately searching physics
textbooks and even old physics GREs for
trivia question fodder. Dr. Bloomfield had
a huge store of fun physics questions at
his fingertips e.g. "You tip over a 1 m
stick and a 2 m stick. Which hits the
ground first?" The representatives from
the two teams, Yogesh Sharma from the
University of Central Florida and Alex
Daly from our own department, excelled
under pressure, and they were rewarded
with bottles of sparkling grape juice. In
the last round, the teams had 5 minutes
to build the tallest possible free-standing
structure out of drinking straws and
masking tape. The Landstanders utilized
a tripod base, and the Yokish team tried
to implement an assembly line process
that never quite took off. The Landstand-
ers scored a definite victory and were
awarded UF SPS quarks t-shirts.

One team uses a three point base in the
competition to make the tallest structure out of

Dr. Hebard, poised with a model, during the lab
tours on the following Saturday

As a consolation prize, SpongeBob
Squarepants mechanical pencils were
given to the Yokish team.
The physics game show was one of
several events in the SPS zone meeting
mixer. Around 4 PM, participants in the
SPS poster and oral presentation
sessions at the SESAPS conference
began arriving at the New Physics
Building where they were entertained by
Drs. Lee and DeSerio with physics
demos. Later, winners of the poster and
oral sessions were presented with prize
money and certificates signed by physics
department chair, Dr. Alan Dorsey. The
awards were followed by a talk from SPS
national director, Dr. Gary White, entitled
"Why Physics? Why 2005? Why
Einstein?" At one point during his talk,
he asked the audience to grab the edges
of a large piece of red spandex and roll
marbles over it in attempt to simulate
planetary motion, drawing some parallels
between the spandex and gravity. After
Dr. White's talk, representatives from
SPS chapters introduced themselves and
discussed their activities. A movie
created by SPS webmaster, Harold
Rodriguez, was played about life in our
own physics department. (It's available
for your viewing pleasure at
www.phys.ufl.edu/-sps.) Dinner catered
by Moe's, the physics game show, and
liquid nitrogen ice cream followed. With
around 60 participants and activities
running from 8:30 AM to 9 PM, it was an
eventful day for our UF SPS chapter.
Kudos to Drs. Yoonseok Lee and Robert
DeSerio and zone meeting student helpers
Erica Bolin, Don Burnette, Justin Cohen,
Kaitlin Harley, and Sumeet Jain.

UF REU: Summer 2006

One of the benefits of being an undergraduate in physics is the amount of
money colleges and institutions will spend on you to help you gain research
experience. A well-known program to this end is the REU or Research
Experiences for Undergrads Program, funded by NSF. NSF sponsors
universities across US (and select ones outside) to accept students for 10
weeks of research in exchange for a housing allowance as well as a stipend,
which is a great opportunity to do physics while having fun in different parts of
the US. www.nsf.gov/home/crssprgm/reu/

Photos are some of the UF participants in this year's program, overseen by
professor Kevin Ingersent. These students conducted research in fields
ranging from nanoscale physics to scales extending out in space.

In Memory of....

Dawei Zhou, a former Physics graduate student, passed away on Tuesday, August 1, 2006 following injuries
sustained in an automobile accident. Dawei was a graduate student from 1985 to 1990 with Professor Neil
Sullivan, and his PhD thesis research was dedicated to studying the properties of impurities in solid hydrogen at low
temperatures, using Nuclear Magnetic Resonance. He also worked as a postdoctoral associate up until 2004, and
he developed new methods for measuring ortho/para ratios in hydrogen gas samples. Dawei is remembered for his
kindness and support of his fellow graduate students at all levels.

"Photos are of special Physics is Fun' show with Gator
mascots, Albert and Alberta

The Department of Physics Lobby
Exhibits opened in December 2002.
The science exhibits include a T-Rex
Hologram, Parabolic Dishes, a Large
Plasma Ball, a Giant Guitar String, the
Anti-Gravity Mirror, and a "Real-Image"
Object display that changes objects
periodically, the Spectra exhibit and
the Chaotic Pendulum.

Visiting students are divided into manageable size groups, usually led by
a Society of Physics Student (SPS) or a volunteering staff or faculty
member. Each visitor has a chance to use the exhibit while the leaders give a
brief description of the science behind the fun of manipulating the display. A
non-scientific survey has found that most students prefer to zap their
friends with the effects of the plasma ball and erupt into fits of screeches
and giggles at the site of a big green T-Rex hologram.

The exhibits are open to the public year round and are available to anyone
who happens to meander into the New Physics Building. Scheduled tours
and school groups are arranged through Professor Henri Van Rinsvelt and
the outreach program webpage http://www.phys.ufl.edu/outreach/
is readily available to visitors who wish to preview the exhibits before
they come for a visit.

An exciting addition to the physics department, the lobby exhibits are a
big draw for area students' curiosity into the world of science.
