More than 200 women undergraduates from the Northeast attended the American Physical Society Conferences for Undergraduate Women in Physics (CUWiP) Jan. 15-17 at Wesleyan. Wesleyan was one of nine institutions from around the country to host a conference. (View an extensive recap of the conference starting on Page 8 of this APS newsletter.)
The APS CUWiP provides female physics majors with the opportunity to experience a professional conference, information about graduate school and professions in physics, and access to other women in physics with whom they can share experiences, advice and ideas.
The program included panel discussions about graduate school and careers in physics, presentations and discussions about women in physics, laboratory tours, student research talks, a student poster session, banquet and career fair.

The American Physical Society (APS) named Clara Moskowitz ’05 the Woman Physicist of the Month for December 2015. A senior editor at Scientific American, she was an astronomy and physics double major at Wesleyan. It was in her senior year that she discovered her “favorite part” of her undergraduate career: her thesis.
“I was fascinated by science from a very young age,” she says, “but so many people feel separated from science—as though they can’t get it. I realized that I like writing and I like to communicate the concepts for nonscientists.” After earning a graduate degree in science journalism at the University of California, Santa Cruz, Moskowitz then joined the online publication Space.com, where she covered NASA’s space shuttle missions and other astronomy news. Two years ago, she joined the venerable Scientific American: “We try to keep it current and stay true to its legacy,” she notes.
Moskowitz recalls her favorite assignment at the magazine—which she focused on both historic import and present application: she served as editor of the theme issue on 100 years of general relativity (Sept. 2015, Vol. 313, Issue 3).
“Einstein is such a fascinating figure; he singlehandedly revolutionized science just by thinking about problems: he went through in his mind exactly what it would be like to ride a beam of light. A hundred years after he proposed the theory, we are still thinking about it, still using it—in our cellphones, GPS devices, and satellites.
“His realization that gravity is not so much a force that pulls things together—but rather that it comes from the shape of space and time—is such a beautiful idea.”
As for her success with the project, editor-in-chief Mariette DiChristina wrote, “Issue editor Clara Moskowitz and the team have created a special report that is profound yet playful and sparkles with the wonder of discovery—rather like the great man himself. We hope you enjoy reading [this issue] as much as we did putting it together.”
Said Moskowitz, “I’m constantly working hard to make science understandable. I want everyone to see what’s so cool about it.”
Reached at the American Astronomical Society’s January 2016 meeting, which she was covering for Scientific American, Moskowitz was most excited about a recent talk she attended about astronomers planning to use telescopes all over the world in conjunction, in order to capture the event horizon of the black hole that astronomers think lies at the center of our galaxy. The project—which could further prove the theory of general relativity, or call for modifications—will take its first images of the black hole in 2017.
“A lot of us are on the edge of our seats until we get the results,” Moskowitz said.
Moskowitz also was back at Wesleyan on Jan. 16 for the Conference for Undergraduate Women in Physics, where she spoke about her career path. She will present a Physics Department colloquium on March 3 about science journalism.

Tom Morgan, the Foss Professor of Physics, recently attended an Atomic Molecular Optical International Workshop held in Cuernavaca, Mexico.
Morgan presented two invited talks, one on highly excited unusual electronic configurations of molecular hydrogen produced by laser excitation and another on laser interactions at the interface between water and air. These topics elicit novel dynamics and provide a different perspective on H2 and H2O behavior.
He also took the opportunity to reconnect with a Mexican colleague, Professor Carmen Cisneros, Institute of Physics, University of Mexico, organizer of the workshop, with whom Morgan has collaborated in the past.

Tom Morgan, Foss Professor of Physics, recently attended the 68th Gaseous Electronics Conference of the American Physical Society in Honolulu, Hawaii and presented a poster dealing with the behavior of giant atoms with an electron far from the nucleus in phase space. Andrew Murphy ’11 and Jace Haestad ’11 contributed to the study.
Phase space is a momentum-velocity space that provides a different perspective on atomic behavior. Looking at atoms from this viewpoint provides a mechanism to uncover new insight into their quantum nature.
Morgan also took the opportunity to reconnect with a Japanese colleague, Professor Tomoyuki Murakami, at Seikei University, Tokyo, whom Morgan spent the month of June visiting in Tokyo. Morgan and Murakami took the occasion to work on a paper on research undertaken collaboratively with Lutz Huwel, Professor of Physics, and Professor Bill Graham of Queen’s University, N. Ireland, on the behavior of the air-water interface after focused laser induced plasma breakdown. The air-water interface is ubiquitous with applications to biology, environmental studies, chemical analysis and medicine, but its detailed behavior is not well understood. The collaboration uses both state of the art computer simulation and experimentation to elucidate its dynamics and structure.

Francis Starr, director of the College of Integrative Sciences, professor of physics, received a $282,000 grant from the National Institute of Standards and Technology in September.
The grant will support “Heterogeneous Dynamics and Assembly Processes in Soft and Biological Materials,” a collaborative research project between Wesleyan and NIST. NIST is expected to fund the project through 2018 with a total amount of $1.66M.
Soft and biological materials are commonly composed of synthetic or biopolymers, or are formed as a result of the supramolecular assembly of small molecule, nanoparticle, or protein molecules into dynamic organized structures. These materials are central to developing new materials for emerging technologies related to energy storage and production, energy-saving light-weight devices, and in the development of diverse new forms of medicine and medical materials that mimic biological processes.
The realization of the promise of this large class of new materials has been limited by the inherent difficulties in understanding and controlling properties and the structural stability of these inherently complex materials. The amorphous, and often hierarchical, structure of these materials make the effective modeling of these materials a challenge.
With support from the NIST grant, Starr and his peers will investigate ways to overcome these challenges and develop these materials for their many intended applications.

For their efforts enhancing undergraduate science education and supporting teaching innovations, two Wesleyan faculty members were named National Academies Education Fellows in the Sciences for 2015-2016.
Francis Starr, professor of physics and director of the College of Integrative Sciences, and Ishita Mukerji, the Fisk Professor of Natural Science, professor of molecular biology and biochemistry, received the fellowships while participating in the 2015 National Academies Summer Institute on Undergraduate Education, held June 14-19 at Princeton University.
The Summer Institute, a five-day program of discussions, demonstrations and workshops, brought college and university faculty together to develop teaching skills. Co-sponsored by the National Academies and the Howard Hughes Medical Institute, Starr, Mukerji and 44 other participants were taught ways to transform the undergraduate classroom and engage students and fellow faculty in the sciences. Current research, active learning, assessment and diversity were woven into the program, creating a forum to share ideas and develop innovative instructional materials to be implemented at each participant’s home institution.
“Wesleyan’s commitment to teaching innovation puts us at the forefront of improving undergraduate education that is essential to prepare future scientists and scientifically literate citizens,” Starr said.
During the institute, Starr and Mukerji developed a “teachable tidbit” with four other institute participants. These tidbits can be implemented in a course during the academic year. In addition, Starr and Mukerji are planning to speak about their experiences to fellow faculty at an NSM luncheon. They’re also working on creating an Academic (Technology) Roundtable meeting with one of the co-directors of the institute.
“Francis and I were both interested in learning these new teaching methods and we’re excited to share them with others on campus,” Mukerji said.

Tom Morgan, the Foss Professor of Physics, is spending the month of June as a visiting professor at Seikei University in Tokyo, Japan. He is collaborating with Professor Tomoyuki Murakami on modeling the evolution of plasma (an assembly of ions and electrons) created by injecting energy into water, “a substance with many interesting properties and applications,” Morgan explained.
The work focuses on water in both the vapor phase and as a liquid.
Morgan also is collaborating on this experimental work with Professor of Physics Lutz Huwel at Wesleyan. Huwel uses a pulse of laser light to provide the energy input to the water.
“The goal of the research is to understand the mechanisms responsible for the transport and evolution of the energy as time passes,” Morgan explained.
An additional focus is on how the laser light radiation energy that is deposited near the surface of water is dissipated into kinetic energy of ejected ballistic water droplets that have been observed in the lab to rise high above the water.
“There are many potential applications of underwater plasmas to the environmental, biotechnical and medical fields,” Morgan said.
The visit to Seikei University is partially funded by presidential initiative funds supplied by the Director of Global Initiatives. The funds support international faculty collaborations.
Morgan met Murakami several years ago through a common collaborator in Belfast, N. Ireland. The scientists share overlapping research interests and have published one paper together.
“Physics is a very global collaborative discipline,” Morgan said.
