dinning hall or you can join us there.
November 14, Colloquium
Friday,
3:30-4:30 p.m., Olin 02
Our colloquium series this fall will be
primarily students reporting on their summer research experiences. Come to hear about the interesting
work. Come to hear about
opportunities for summer research in your future. Come for the refreshments!
Jill Bingham: ÒLamb Wave TomographyÓ
Lamb waves are ultrasonic guided
waves that propagate relatively long distances in thin plates. They may be better than traditional
ultrasonic techniques for nondestructive testing of airframe skins, storage
tanks, and pipes. By recording the
arrival times of the first arriving Lamb wave mode for many different
projections (transducer transmit and receive positions), an image of the
material is tomographically reconstructed using the simultaneous iterative
reconstruction technique (SIRT).
The task now is to refine the method and the algorithms to speed up the
process and improve the images.
Ted Holby: ÒA Two Dimensional Continuum Model of
Globular Proteins and NucleationÓ
Some membrane proteins are confined
to quasi-two-dimensional space.
For this reason, a two dimensional version of a mean field theory of
crystal nucleation put forth by Talanquer and Oxtaby (J. Chem. Phys. 109, 223
(1998) ) is studied and compared to its three dimensional counterpart. By solving the Euler-Lagrange equations
of the grand canonical free energy functional for the density and phase field
numerically, the radial profile of a critical nucleating droplet is
obtained. It is found that like
the three dimensional model, the number of particles in a critical droplet
diverges as the temperature approaches the metastable critical point, due to
the divergence of the correlation length.
David Steussy: ÒLIGO: Data AnalysisÓ
LIGO is a project designed to
detect gravity waves from very large astrophysical events. The nature of these waves means that
the experimental problem of detecting them is quite challenging, and highly
influenced by noise. My work for
this past summer was spent analyzing data in order to attempt to characterize
the detector system and make a 'veto', by which signals that look like events could
be automatically ruled out as having been caused by other environmental
factors.
FYI
If you'll be in Northfield over winter break, why not tutor
a couple of AP physics students from Northfield High once a week for some
experience and some cash. If
you're confident in your 113 skills and have some knowledge of atomic and
nuclear you're qualified!
You can check out the class on the web. (My brother's the one with red hair
half hidden in the back row.)

2004 REU and
Internship Information
List of
REU and internship opportunities are also on the Carleton Physics Web page at http://webapps.acs.carleton.edu/curricular/physics/for_students/summer_jobs_internships/
University of California, Los Angeles REU in Physics and
Astronomy scheduled for summer 2004. This program is described on our website
at http://www.physics.ucla.edu/reu
. Our research program is aimed at
highly motivated students in the physical sciences all across the country, who
wish to engage in an intensive 10-week research project with a UCLA faculty
member working in Physics or Astronomy, and who are in their third or fourth
year in college but have not yet graduated by the summer 2004. The deadline for
application is Feb 21, 2004.
Fermilab Internships for Physics Majors (IPM)
Program Objective To introduce students majoring in physics to the current
methods and problems of high energy physics research. A small number of
students from closely related disciplines such as computer science or
engineering are also accepted into the program. For more information: http://ipm.fnal.gov/ Applications
will be accepted beginning Dec 1, 2003.
Kitt Peak National Observatory REU. Six research
assistant positions for summer 2004. Contact: REU Program, Kitt Peak National
Observatory, P.O. Box 26732, Tucson AZ 85732-6732. Web: http://www.noao.edu/kpno/reu. Deadline:
January 26, 2004.

Mayo Clinic's "Summer Undergraduate
Research Program." Applications for the SURF program at Mayo close on
Fedruary 1, 2004. Information on the SURF program (including on-line
application forms) is at http://www.mayo.edu/mgs/surf.htm
National Institute of Standards and
Technology (NIST) Materials Science and Engineering Laboratory Gaithersburg,
MD. Summer Undergraduate Research Fellowship (SURF) in materials science and
engineering research. Deadline: Feb 15, 2004. http://www.surf.nist.gov/surf2.htm
Space Studies Board Internships The internship
provides promising undergraduates an opportunity to work in the area of civil
space-research policy in the Nation's capital, under the aegis of the National
Academy of Sciences and affiliated organizations. The successful candidate will
have completed his/her junior year, majoring in physics, astronomy, chemistry,
biology, or geology, and should have long-term career goals in research,
applications, or policy in one of these areas. Interns work closely with the
Board's staff and committee members on a broad range of issues covering all
aspects of scientific research conducted in space and associated ground-based
activities. Applications are due by February 15, 2004. http://www.nationalacademies.org/ssb/intern.htm
