Weekly Calendar

March 4, Physics Table, Tuesday, 11:30-12:30 p.m., LDC 113 (Fireplace Room). Join the Department staff for lunch. We can meet on 3rd Olin at 11:25 for the short walk to the dinning hall or you can join us there.

March 7, Goodsell Open House, Friday, 7:30-9:30 PM., Goodsell Observatory. View planets, stars, galaxies, and nebulas through the Observatory telescopes if clear. Dress warmly! The meteorite collection, newly and beautifully documented by Carleton geology majors Amalia Doebbert '03 and Hilary Gittings '02, will also be on display.

Comps Calendar

March 3, John Graner, "PET, SPECT, CT, Ultrasound and MRI: A Tour of Medical Imaging", Monday, 3:10-4:20 p.m., Olin 02

March 5, Brian Knight, "Femtosecond Lasers and Applications to Femtochemistry" , Wednesday, 3:10-4:20 p.m., Olin O2.

March 7, James Lloyd, "THz Spectroscopy", Friday, 3:30-4:40 p.m., Olin 101.

Introductory papers of upcoming talks are available in binders in the second and third floor lounges. These will provide you with important background information and a brief outline of the talks to be presented.

FYI

Hip Hip Hooray!

Nelson Christensen was recently awarded tenure. That was the culmination of a review that finally concluded with an official announcement from the Board of Trustees in February. Several of you had participated in that process by responding to a questionnaire from the Dean last December. Those responses were an important component of the consideration and eventual decision.

Kris Wedding '91 will be joining the Physics Department for the next academic year in a one-year temporary position. Kris graduated from Carleton in '91, then went to the University of Wisconsin where she completed her Ph.D. in Medical Physics. Right now she's in California splitting her effort between professional consulting about MRI research and teaching physics at the University of California at Hayward. She's currently scheduled to teach P350 Advanced Classical Mechanics in the fall, P126 Physics of Laboratory Instrumentation in the winter, and P112 Elementary Physics in the spring, but we have suggested that she think about teaching P261 Medical Physics, since it is a "natural" for her. We'll let you know how that comes out.

Join us in congratulating Nelson and, when you get the chance next fall, in welcoming Kris back to Carleton.

2003 REU AND INTERNSHIP INFORMATION

List of REU and internship opportunities are also on the Carleton Physics Web page at http://physics.carleton.edu/Updates/finternships.html

Gravity Wave Research: Work with Nelson Christensen on the analysis of data from the Laser Interferometric Gravity Wave Observatory (LIGO). We will try to determine where noise sources are influencing the data. LIGO has hundreds of environmental monitors (seismometers, magnetic field sensors, etc); we will look for correlations between the LIGO data and the signals from the environmental monitors. The student will likely travel to one of the LIGO sites for a week or two during the summer. Interested students should contact Nelson.
