News from the Franklin and Marshall College Department of Physics & Astronomy, Fall 2003, http://www.fandm.edu/Departments/Physics/default.html
SCOTT LACEY JOINS PHYSICS AND ASTRONOMY FACULTY
Scott Lacey has joined the department as a tenure track Assistant Professor of Physics. Scott earned his Bachelor's degree in Astronomy and Physics from Colgate University. He graduated from Colgate Phi Beta Kappa and earned the award for Outstanding Physics Student. His recently completed thesis is titled: “Ray and wave dynamics in three dimensional asymmetric optical resonators”. He received his Ph.D. from the University of Or4egon. Lacey was recently published in an issue of Physical Review Letters, quite an achievement for a physicist at any stage of his career.
Scott and his wife, Sarah, bought a house near campus and are working on refinishing and repainting their new home. He has also recently joined the F&M Rugby Team as a coach.
All members of the department join in welcoming Scott and Sarah to the F&M family.
30 YEARS OF WOMEN IN PHYSICS AND ASTRONOMY CELEBRATED
In 1969, Franklin and Marshall College admitted women to the school and in 1973 we awarded our first bachelors degree in physics to a woman, Jean Olivia Turn. Special events will be held during Alumni Weekend, October 24-26 to celebrate 30 years of women in physics at F&M. A dinner is scheduled for Friday evening, October 26, followed by a special evening of star gazing at the Grundy Observatory. Other events are department tours on Saturday morning, in conjunction with our regular reception for alums and a Hot Topic talk on Saturday afternoon.
All Physics and Astronomy alumna have received a questionnaire which will be used to create a directory of ourwomen graduates and will be available at the celebration. We are proud of our alumnae and want to honor those who blazed the trail for others. Any questions or comments, please contact Dr. Linda Fritz at lfritz@fandm.edu
NATHAN MCGOVERN IS NAMED WILLIAMSON MEDALIST AT COMMENCEMENT
The Williamson Medal is the highest undergraduate award a student can attain while at Franklin and Marshall College. This past May, the award was presented to Physics and Religious Studies major Nathan McGovern ‘03 in recognition of his passion for learning, his contributions to intellectual discourse in this community, and his commitment to helping others.
Nate gave the following message to his fellow students: “Nobody expects any one of us to carry the weight of the world on our shoulders. It takes vibrant communities of human beings, full of spirit and conviction, to change the world. If each of us tries to make a difference alone, our energies will be quickly sapped by an apathetic environment, and our idealism will be turned into cynicism. But if we pool our energies, our talents, our convictions, our hopes, and our dreams together — oh, what a difference we will make! F needs a spiritual renaissance— and I believe it will find one. As for those of us who are graduating — our time at F&M is finished, but our time in the world-at-large has just beg
If you have been lucky enough while at F&M to find that something in one of your experiences here — that spark that ignites a fire inside you and gives you the belief, indeed the assurance, that you can make a difference — then take that with you wherever you go. And if not, don’t lose hope, and don’t stop looking for that spark. There is a moment of conversion on every road, a moment of insight under every tree, and a moment of possibility in every sign that says, “Come join us! We make a difference here.”Quoting Prof. Greg Adkins, Nate’s mentor in the Physics Department, “a quote from Einstein comes to mind when I think of Nathan: “I want to know God’s thoughts. . . the rest are details. ” Professor Adkins may be right, for Nathan plans to pursue a doctorate in religious studies at the University of California at Santa Barbara. He expects to research the origins of the Buddhist religion.
It is with great pride that all of us in the department of Physics and Astronomy congratulate Nate on this very important award.
PHYSICS AND ASTRONOMY CLUB STARTS NEW YEAR
The F&M Physics and Astronomy Club began the new year with a booth at the CAF and a picnic at Buchannan Park. This year the CAF demonstrations placed some emphasis on astronomy and featured a sun spot viewer along with our usual frozen banana demonstration. The picnic was a hit, as usual, and even though there was no volleyball this time, there were some interesting things happening with nitrogen and a puddle behind the pavilion.
President Margaret Mitter has some fun and educational projects planned for the future including a trip to NASA Goddard, another ever popular Deconstruction Night, a rubber band car race, movie night (old sci fi movies and movies that includes “just awful physics”), and a visit to the Grundy Observatory to catch a glimpse of Mars before it moves out of our vicinity.
Last year’s big event at Spring Arts weekend was a car bashing event where students paid to take 3 whacks at an old junker car donated by senior Brendan Meyer. It was a “smashing” success and even Associate Dean Ann Steiner joined the fun and took the first swing. A good deal of preparation was put into this event by club members and Steve Spadafore, who’s assistance was invaluable in making this a safe and fun project.
This year’s officers are: Margaret Mitter, President, Frederika Edgington-Giordano, Vice President, and Patrick Totaro, Treasurer. The club is open to all F&M students who have an interest in Physics and Astronomy.
PROFESSOR MILINGO TO REPLACE DR. BACKMAN IN A TWO YEAR VISITING POSITION
Dr.Dana Backman has taken a special leave to join NASA, heading up the SOfIA program. (See article on page 5) During his absence, Professor Jacquelynne Milingo will be teaching Astronomy courses as a two year visiting professor.
Jackie is a native of Phoenix who grew up in Kansas and earned her B.S. in Physics and Astrophysics from the University of Kansas. She earned her Ph. D. from the University of Oklahoma in 2000. Her thesis was titled: “Sulfer Abundances in the Milky Way Disk from Type II Planetary Nebulae. For the past three years she has been teaching physics and astronomy at Gettysburg College.
Jackie knits, hikes, enjoys her cat Frederika and sings. We all welcome Jackie to the department!
HACKMAN SCHOLARS REPORT RESEARCH
This past summer several of the Physics and Astronomy majors worked as Hackman Scholars.
Dan Weber and Prof. Ken Krebs report on the effects of chelating the lanthanide prior to doping on the control of non-radiative mechanisms. “Lanthanides typically exhibit weak luminescence in sol-gel produced alumina due to the competition of non-radiative and radiative decay mechanisms. In this report, we present our investigation of the effects of chelating the lanthanide prior to doping on the control of non-radiative mechanisms. Samples of Eu3+(EDTA) were prepared. dissolved into solution, and used to hydrate alumina alkoxides to produce the sol-gel monoliths. Samples of the alumina were heated in intervals to final temperatures ranging from 100 to 700 degrees C. The effects of the heat treatment on the optical spectra of the Eu3+ impurities shows that Eu3+ occupy a single crystallographic site in the chelate, but as the chelate decomposes the impurity sites reconfigure as the impurities coordinate with nearby oxygen. During reconfiguration, the alumina structure densifies restricting lanthanide clustering and local incorporation of hydrogen, thus reducing the presence of non-radiative decay mechanisms.”
Ted Seemuller and Prof. Christie Larochelle worked on a project to examine energy transfer between mixed silver/gold dicyanide donors and lanthanide acceptors.
“The first step is growing the crystals in a solution of agar gel using concentrations of 25% gold and 75% silver dicyanide ions. After studying the energy levels of the gold/silver donors, single crystals are doped with varying concentrations of Europium to examine energy transfer. Energy transfer is studied using a combination of steady-state excitation and emission spectroscopy, lifetime measurements and time-resolved spectroscopy. A cryostat is used to examine the energy level properties of the crystals at temperatures ranging from 77K to room temperature. Results show strong luminescence at all temperatures in contrast with prior results showing poor luminescence at room temperature in pure silver or gold crystals, and energy transfer from the gold and silver dicyanide donors to the Europium acceptor.”
Chris Hobson and Prof. Ken Krebs report on the Optical properties of Eu3+:Y_2O_3.
Our synthesis involved the hydrolysis of an Yttrium Alkoxide followed by a polymer condensation reaction. The final solids were calcined to 800 degrees C to remove any remaining organic molecules. The luminescent properties were studied using emission, photoexcitation and lifetime measurements. We find that through the sol-gel process Eu3+ impurities are incorporated into the crystalline structure of the Yttrium Oxide substitutionally for Yttrium ions. The overall structure was determined to be that of typical Yttrium Oxide by x-ray diffraction.
PROF STUBBINS PRESENTS STUDY IN ITALY
Last year, Luke Oeding did a yearlong independent studies project with me entitled Phase Space Quantum Mechanics. Luke receive departmental honors due in part to this work. This work focused on representing quantum mechanics in classical phase space similar to what is done with the Wigner function.
At the end of last summer, I presented work related to the project Luke did at a conference in Italy called "Mysteries, Puzzles and Paradoxes in Quantum Mechanics" held in Gargnano on Lake Garda, the largest lake in Italy. It's about 70 miles east of Milan. My poster was entitled Quantum Trajectories in Momentum Space.
While in Italy, I also visited Florence, Pisa and Milan. While in Pisa, I visited the cathedral where supposedly Galileo noticed that a light fixture hanging from the ceiling swung with a constant period and deduced that a simple pendulum could be the basis of a timepiece. The photo is of the bell tower for the cathedral in Pisa, better known as the leaning tower of Pisa.
*Dr. Stubbins at the Leaning Tower of Pisa
Two students worked with me this summer as Hackman scholars on looking at Feynman propagators in Bohm mechanics. In Bohm mechanics, an ensemble of particles move with well determined trajectories in such a way that they reproduce the correct quantum probabilities. This summer we showed that all particles for the Feynman propagator wavefunction converge to a point signifying that there is a probability of one that the particle is at that location. This is in agreement with the standard meaning of the propagator. Before this work, there were no demonstrated examples of trajectories converging to a single point in Bohm mechanics.
ASTRONOMY HAPPENINGS
The Astronomy program went through lots of changes and went to a couple different countries this year. Over the summer Dana Backman went on a 2-year leave to be Assistant Director of SOFIA (see article on pg 5), Elizabeth Praton went on a 1-year sabbatical to Massachusetts, and we gained former Gettysburg Astronomer Jacquelynne Milingo who is a wonderful asset to the program (article on pg 2).
Arizona isn't really another country but that's where we started out. In two observing runs during the winter and spring 2003 students from the new AST 240 = Observational Astronomy course went to the NURO (National Undergraduate Astronomy Observatory) in Flagstaff Arizona, a 31-inch optical telescope with CCD electronic camera that is operated by Lowell Observatory for a consortium of 14 small colleges and universities that includes F&M, Gettysburg, and Dickinson colleges.
In January, the week before the start of classes, Prof. Backman was accompanied by Amanda Carr '04, Jana Bilikova '04, Zach Hosford '03, Matt Powers '05, Jeremy Steinbacher '03, and Amanda Williamson '03.
The weather conditions were good and we observed our usual set of very active, rapidly rotating young solar-type stars in the Pleiades and alpha Persei clusters.
In March, during spring break, Profs. Backman and Lommen were accompanied by Sarah Aronoff '05, Jessica Fox '05, Daniel Lindenberg '03, Ian McNabb '03, and Josh Kauffman '04. The weather was not so good, we only took data for 1/2 of one night during the run, but we still had some fun .
Note that we managed to afford the trip partly because AST 240 students Jennifer Donovan '03 and Candace Grand Pre' '03 who had already been to NURO twice each, graciously offered to give up their 'seats' to the benefits of the other students in the class.
Also over spring break, Jennifer Donovan met Prof. Lommen at the Arecibo Observatory 300-m telescope in Puerto Rico where they observed the fastest spinning stars in the universe, pulsars. (Puerto Rico is also not a different country, but they do speak another language). Jen is shown here taking the cable-car up to the platform. Behind her you see the dome which houses the receivers. They're about 500 ft above the ground at this point.
Over the summer, Donovan and Lommen continued their work at the Anton Pannekoek Instituut in Amsterdam, Netherlands where Jen made a beautiful poster which announces that the radio and x-ray fluxes in the Vela pulsar are correlated, i.e. when its bright in radio waves its also bright in x-rays. Perhaps this sounds patently obvious to you, but in fact not much is known about the relationship between these types of emission. Jen's work sparked quite a lot of interest when Jen presented this at the International Astronomy Union Symposium in Sydney, Australia in late July.
SPECIAL MARS VIEWING IS SUCCESSFUL COMMUNITY EVENT
This summer Mars moved closer to earth than it has in approximately 55,000 years.
It was decided this would be a perfect time to open the observatory to the public for several nights so that everyone who was interested could view the red planet through the big telescopes
The response was fantastic! The calls to the office were almost overwhelming. People saw the article in the paper and called to ask questions and get directions to the observatory for a week or so before the event. Over 400 people came to the Grundy Observatory over a three night period, August 28-30. Even though the time was late, 11:00 p.m.- 1:00 a.m. and the lines were long at times, everyone was very patient and seemed to enjoy the occasion. There were people of all ages, from preschool to seniors.
Much of the credit for the success of the event goes to our amateur astronomer, Jeri McClune. Jeri has run thepublic night program for several years and it was his idea to open the observatory for a special viewing of Mars. After hearing the phone response he decided to keep it open for three nights rather than the original two nights.
It is also important to mention that Mars is still visible as of this writing, and will be over the next two or three months. It is now higher in the evening sky and so can be viewed earlier, at about 10:00 p.m.
The normal time for the public nights at the observatory is the third Monday of every month of the year when the weather is good (arrive 1/2 hour after dusk). On a normal night, we have 10-20 people at the observatory public night.
BACKMAN TAKES TWO YEAR LEAVE TO WORK AT NASA
Dana Backman, Professor of Physics and Astronomy began a two year leave of absence this summer to work at NASA.
This writer asked Dr. Backman to write an article on what SOFIA is and what his job entails. Following is what he wrote:
SOFIA, the Stratospheric Observatory for Infrared Astronomy, will be a 2.5 meter (100 inch) diameter telescope onboard a specially modified Boeing 747 jet. The idea is that this flying observatory can get above most of the atmosphere of the Earth and be much better than the same size telescope would be on top of a mountain, but on the other hand is much cheaper and easier to maintain than a space telescope (this one comes home every night!). There has already been a flying observatory called the Kuiper Airborne Observatory that operated from 1975 to 1996 which had a much smaller telescope inside a smaller airplane, SOFIA is the Kuiper's replacement. The telescope is open to the outside but isolated from the cabin by a bulkhead, so the working environment onboard won't be much different from flying on a 747 commercial airliner
SOFIA is still under construction at the L-3 aerospace company's facilities in Waco, Texas. The telescope primary mirror was installed in July. We hope that test flights will start next May and then about 6 months later SOFIA will move to its permanent base here at NASA's Ames Research Center in Silicon Valley (suburban San Francisco).
My position is one of the 4 associate directors of SOFIA; I'm in charge of the Education and Public Outreach office [my Ph.D. advisor Eric Becklin is the observatory director].
One of my main projects is to devise procedures for choosing and training teachers from schools around the country who will fly on SOFIA and collaborate in research with the astronomers - sort of like junior varsity "Teachers in Space." So far I've spent a lot of time going to science teacher conferences giving presentations about SOFIA and telling them to get ready to apply to fly and work on SOFIA.
All of Dr. Backman’s colleagues in the department wish him the best of luck in this venture.
Foundations Fellow Group Report
Prof. Linda Fritz is a member of the Foundations Fellows Group and reports that theymet three times over the summer to discuss how they would integrate the visit of Daniel Kammen, our Foundations Fellow, into our courses. They also discussed how they could help each other with courses by doing guest lectures or providing reading material or "expert advise.
They decided to use two articles by Kammen (and others) as a common reading. They are "Renewable Energy: A Viable Choice", Environment, volume 43, December 2001 and "Equity and Greenhouse Gas Responsibility", an opinion piece which appeared in the "Science's Compass" section of Science, volume 289, September 29, 2000. Linda Fritz and her preceptor are working on discussion questions for the two articles. The questions will be shared with all five instructors. Kammen will visit each class, and all five instructors intend to require that their students attend Kammen's public lecture and respond to it.
Another result that has emerged from working together to bring in a common speaker is that they are also working together to enhance each other's classes. They have exchanged readings and information on web resources. There are nine guest lecturer appearances already scheduled, with more possible as the semester progresses. Dorothy Merritts will visit Linda Forbes' Business, Culture, and the Natural Environment (CCS 141) class, Linda Fritz's Energy Issues in Science and Society (NTW 108) class, and Eiman Zein-Elabdin's Environmental Ethics (CCS 127) class to discuss how scientist investigate past climates and model future climates. Linda Fritz will visit Dorothy's Climate Change (NTW 135) class and Eiman's class to discuss world- wide energy consumption and distribution of resources. Peter Fields will visit Dorothy's class and Eiman's class to discuss species migration. Eiman will visit Linda Forbes' class to discuss environmental ethics, and Linda Forbes will visit Dorothy's class to discuss the culture of consumption. She may also visit Linda Fritz's class to discuss standards of living in industrializing countries.
As you can see this interaction has produced not only an excellent speaker as part of the CLAS colloquium, but also the beginning of what are likely to be ongoing collaborations between faculty members from diverse fields.
PHYSICS DEPARTMENT AND VELCRO CORPORATION COLLABORATE
Franklin and Marshall College Physics Department has begun a collaboration with Velcro Corporation. Based in , Velcro has loaned the department a tensile strength tester to investigate various hook and loop closure combinations. Due to a nondisclosure agreement, details are not available, but two students have done their independent study. Jim Schilling’05 (who is now at Penn State in the 3/2 program) did his independent study in the Spring of ‘03 (390) and senior Dan Weber’04 is doing his 490 study in the fall of ‘03 and will continue in spring ‘04. Professor Ned Dixon is serving as advisor on the projects.
NEW LOUNGE PLANNED FOR MAJORS
Hackman P215, the former optics lab, will be converted into a student lounge/study area with a kitchenette and personal study cubbies.
The plan calls for a wall to divide the lab lengthwise forming a public gathering side and a private study side. The public side will provide a large open space with tables, white boards and comfortable seating where students can gather in groups to study, hold meetings and host events like deconstruction. Features such as floor lamps, area rugs and windows in the wall allowing for natural light will be incorporated to provide a feeling of warmth. In a small side room off the public area will be a kitchenette with sink, fridge and table. The far side of the dividing wall will house a quiet study area divided into four rooms. Each room will have several individual desks for junior and senior P&A majors. Students will be able to personalize their space. Hard wired Ethernet connections will be available at each desk. The upper reaches of the ceiling, pipes and ducts over the entire space will be painted black so as to make the mechanicals disappear into the ceiling space.
The estimated cost of the project is $55,000 and it is anticipated that the renovation will be completed by the end of Winter break.
CLASS OF 2003 PHYSICS AND ASTRONOMY MAJORS AND MINORS
On Sunday, May 18, 2003, Franklin and Marshall College graduated Physics and Astronomy majors and minors Receiving their diplomas were Jennifer Donovan, Candace Grand Pre, Ian McNabb, Cedric Mason, Nathan McGovern, Brendan Meyer, Luke Oeding, Jeremiah Seachrist, and Jeremy Tomaszewski. Congratulations to all our graduates.
PROFESSORS WORK TOGETHER ON FOUNDATIONS COURSE
Report from Ken Krebs: This summer I worked with Linda Fritz, to learn her foundations course NTW 108 Energy Issues in Science and Society. Much of our time was spent discussing the goals for the course and the syllabus designed to accomplish those goals. Our work had the added dimension that we know I will most likely be offering the course during the 2004-2005 academic year. I am continuing to work toward teaching NTW 108 in two ways: firstly, I am working this semester with Linda and her preceptor to develop grading rubrics for some of the course writing assignments based on my recent participation in the Faculty Writing Workshop. Secondly, I am developing a syllabus of my own for the course, which will be at most a modification of the syllabus Linda already uses. I am particularly interested in incorporating studies of the use of wind, solar, and bioconversion technology in Lancaster County. My main problems still to be addressed are how to include the local studies without lessening the global focus of the course and selecting appropriate readings for the students. My discussions with Linda have been extremely helpful by introducing me to many sources of information of which I had been unaware. The time we spent, and continue to spend, together working on the course is certainly improving my ability to teach the course.
Report from Linda Fritz:: Crafting good writing assignments and rubrics with which to grade them has always been a challenge for me. Discussing these assignments with Ken over the summer and continuing our discussions during the semester has been and will continue to be very helpful to me. One of the greatest challenges with the NTW 108 course is the vast number of topics and amount of material that could be incorporated into the course. Ken's fresh perspective on the syllabus, structure of the course, and activities to engage the students continues to be very useful.
I believe that Ken and I will soon have versions of NTW 108 which are similar enough to warrant being called the same course, each having our personal stamp.
RECENT NEWS FROM ALUMS
Nabeel Anwar writes: “I am living in Colorado and working at the Denver office of an economic, financial and strategy consulting company based in Boston. “ About Colorado he says, :”I am insanely in love with the place, and make an effort to go sightseeing every weekend! I've been to the Rocky Mountain National Park, Grand Lake, Hot Sulphur Springs (near Granby), and Yellowstone National Park!! (Wyoming). Yellowstone was fantastic! I really had fun there, never have seen anything like that before.”
Jen Donovan ‘03 wrote to say she is in New York at Columbia, has an apartment and is settling in to grad school. She plans to visit campus over homecoming weekend and looks forward to attending the Women in Physics celebration. (See page 1).
Due to the 30 Years of Women in Physics celebration, we have heard from many of our women grads. Following is a list of those who have contacted us: Susan Smith Baish ‘78, Jennifer Donovan ‘03, Niki Hatzilambrou 85, Nancy Franzoso Glonseth ‘83, Anne Hultgren ‘99, Johanna Savader Kidwell ‘90, Eve Kuriansky ‘78, Brenda Baracka Lewis ‘86, Lisa Davidson Megidesh ‘81, Janet Seeds ‘75, Anne Dudrick Spivey ‘88, Michelle Switala ‘91, and Rebecca Eby Williams ‘95. We hope to see many of them at our dinner on Oct. 24.
If you are interested in getting in touch with any of our alums, please email the department secretary, Lynn Pino (lpino@fandm.edu), and if we have their information we will pass the message along.
Hackmans (Con’t from pg 3)
Jana Bilikova and Beth Praton report on quantifying the bull’s eye effect:
In this project, we were investigating a promising method for quantifying the so-called bull's eye effect - an illusion that the observer is surrounded with giant concentric walls of galaxies. This effect is caused by the method used to estimate the galaxy distances from their redshifts, which would only work if the galaxies had no other motion than that caused by the expansion of the universe. The extra motion caused by local gravitational influences changes the resdhift slightly, and this results in enhancement of the structures lying in our line of sight.
The method for evaluating the bull's eye should allow us to pick up the effect as well as get a stronger signal when we see stronger bull's eye. The method we were testing was successful in picking up the effect; however, it did not show stronger signal as we changed our sample to show stronger bull's eye effect. Therefore the method still need to be worked on to yield useful results.
DR ADKINS ASSUMES DEPARTMENT CHAIRMANSHIP
Upon Dana Backman’s departure this June, (See article on page 5 ), the chairmanship of the department was assumed by Greg Adkins, Professor of Physics. Dr. Adkins will serve as chair for a three year term.
Stellar Structure Theory and Other Projects Studied
Frederika Edgington-Giordano and Greg Adkins worked together on a project in stellar structure theory. They studied the equations describing stellar equilibrium, including the effects of nuclear energy generation and energy transport. As a relatively simple approximation, they studied a polytrope model numerically and compared results to known properties of our sun.
Jordan McDonnell, a local high school student, worked with Greg Adkins on a number of projects in general relativity, including several explicit calculations of gravitomagnetic forces and the McVittie solution for a star embedded in an expanding universe.
COLLEGE SHOCKED BY TRAGIC LOSS
Franklin and Marshall College has lost an exceptional student Sarah Aronoff, a psychology major and astronomy minor died tragically in a kayaking accident off the coast of Cape Cod in mid October.
President Fry, in a message to all FSA, said, “Sarah will be missed deeply by all who knew her - now, and for a long time to come Sarah, was a member of the track and field and cross country teams, was a dynamic young woman active in a number of campus activities. Sarah's professors recall her enthusiasm and dedication. Her coaches and teammates recall her energy and passion for athletic competition. And everyone remembers her ever-present smile that illustrated her delight in life.”
Sarah spent a lot of time in the department last year and always had a cheerful smile and “hi” for everyone. She was a teaching assistant in the astronomy program and travelled to NURO with Professor Lommen and other students.
All of us in the Physics and Astronomy Department will remember Sarah and we offer our condolenses to her family. She will be missed.
