Physics professor Nora Berrah has been named a 2018 Fellow of the American Association for the Advancement of Science (AAAS). Prof. Berrah has been recognized for her distinguished contributions to the field of molecular dynamics, particularly for pioneering non-linear science using x-ray lasers and spectroscopy using synchrotron light sources.
Step into a fall 2018 class section of PHYS 1602: Fundamentals of Physics II, and you’ll find a scene that’s far from the large introductory science lectures common on most college campuses.

To start, the class of 30 students sits at several triangular workspaces, which today are covered with wires, coils, magnets, and power supplies that the students are using to demonstrate electromagnetic induction. At the start of class, the instructors provided a short lecture before the students set off on their own problem-solving tutorials.
Now, the instructors move from group to group, stopping to answer questions, as students shuttle back and forth to the whiteboards that line the classroom walls.
It’s a scene that’s about to become common in UConn physics courses, thanks to renovations to the Edward V. Gant Science Complex, according to Barrett Wells, professor and head of the Department of Physics.
“We’re rebuilding our classes from the ground up,” he says. “It’s the basis for what we’re going to spread across most of our introductory courses.”
The curricular redesign, says Wells, will replace the typical large-lecture format with smaller classes, utilizing five new studio-style physics learning laboratories to be added to the Gant Science Complex in 2019. These changes will promote active learning, collaborative problem solving, and faculty-student interaction, he says.
“This is a trend we’re seeing in our discipline,” Wells says. “Restricting class size to promote students actively participating during class has been documented to help them achieve and learn more across the board.”
Lecture Meets Lab
Traditional science courses, including those in physics, typically consist of three weekly lectures that hold 100 to 200 students, with once-per-week lab sections where students practice the concepts they learn in lecture.
But this setup poses challenges for professors and teaching assistants to cover the material at the same rate, often causing lecture and lab sections to fall out of synchrony, says Diego Valente, assistant professor in residence of physics and instructor of Fundamentals of Physics II.
In addition, many physics concepts are difficult to teach within the logistical setup of a lecture, and the instructors may have a difficult time knowing whether students comprehend the material, says Valente.
To combat these issues, the Department of Physics piloted redesigned versions of Fundamentals of Physics I and II, the introductory sequence for physics majors, in the spring and fall of 2018, respectively.

The new courses, which will use the physics learning laboratories, merge the lecture and lab sections into three 2-hour class periods per week that hold up to 54 students. Classes are led by the same professor and graduate students.
“[The studio classrooms] allow instructors to interact with students more frequently and discuss concepts with them in depth,” says Valente. “Previously, hands-on group work was limited to lab courses. Now, every single day in class there’s some kind of group activity where students solve problems.”
Lukasz Kuna ’14 (CLAS), ’17 MS, a physics Ph.D. student and teaching assistant for Fundamentals of Physics II, agrees.
“We can present a topic that’s somewhat difficult to understand, and then attack it from all angles,” he says. “It certainly should be the way physics is taught, because it prepares you for more difficult problem solving.”
A Learning Community
The studio learning model also increases the amount of time students spend working collaboratively, says Valente.
Ian Segal-Gould ’21 (CLAS), a physics and mathematics major enrolled in Fundamentals of Physics II, says that the class fosters the collaborative problem-solving that is expected of professional physicists.
“In lecture-based courses, people look at the professor,” he says. “They’re not talking to each other, they’re not solving the problem—they’re looking at somebody else solve the problem. In the real world, physicists work together, so I think the interactive component to this course is on the right track.”
Physics major Megan Sturm ’21 (CLAS) says that working in small groups helps build camaraderie and exposes her to new ideas.
“I know at least half of the class, and it’s way easier to learn that way,” she says. “Someone else will ask a question or say something during the lab that I wouldn’t have even thought about.”
Sturm also says that she enjoys the frequency of interaction with the instructors, noting that Valente circulates through the class, asks students specific questions, and engages in hands-on work with them.

“He’s way more approachable, so when I’m having trouble with things, I don’t have a problem going to office hours,” she says.
Kuna, who has taught for three years in the Department, says that the faculty-student interaction helps him better gauge how students are learning the material.
“Traditionally, if you’re teaching in a large lecture, you somewhat lose the students when they go to lab,” he says. “Here, you get to see where your class stands.”
With a target completion date for phase one renovations set for fall of 2019, the Department is gearing up to redesign other introductory courses, including Physics for Engineers and Physics with Calculus, a general education sequence taken by many pre-med students.
“This is important because we offer courses to majors across the University, and we’re teaching more students each year,” Wells says.
“Our goal is to develop not just comprehension of physical concepts, but also transferable skills–things like communication through group work and computer programming, which students can use in their professional lives,” adds Valente.
He says that these investments in teaching and infrastructure give UConn an advantage in addressing instructional issues common at institutions across the United States.
“This is a really large-scale venture we are doing, something a lot of comparable institutions aren’t able to do,” Valente says. “It shows that UConn is making a big commitment to physics education.”

Meet the Researcher: UConn Astrophysicist Cara Battersby

A young Cara Battersby once scrawled out the phrase “Science is curious” in a school project about what she wanted to do when she grew up.
This simple phrase still captures Battersby’s outlook on her research about our universe.
Recently shortlisted for the 2018 Nature Research Inspiring Science Award, Battersby has been working on several projects aimed at unfolding some of the most compelling mysteries of galaxies near and far.
“I’m really interested in how stars are born,” Battersby says. “They’re the source of all life on Earth.”
Many of the “laws” we know about how stars are formed are based exclusively on observations of our own galaxy. Because we don’t have as much information about how stars form in other galaxies with different conditions, these laws likely don’t apply as well as we think they should.
Battersby is leading an international team of over 20 scientists to map the center of the Milky Way Galaxy using the Submillimeter Array in Hawaii, in a large survey called CMZoom. She was recently awarded a National Science Foundation grant to follow-up on this survey and create a 3D computer modeled map of the center of the Milky Way Galaxy.
The center of our galaxy has extreme conditions similar to those in other far-off galaxies that are less easily studied, so the Milky Way is an important laboratory for understanding the physics of star formation in extreme conditions.
By mapping out this region in our own galactic backyard, Battersby will be able to form a better idea of how stars form in more remote areas of the universe.
“I love that astrophysics is one of the fields where I can get my hands into everything,” Battersby says. “Stars are something real that you can actually see and study the physics of.”
Battersby is also investigating the “bones” of the Milky Way. Working with researchers from Harvard University, she is looking at how some unusually long clouds could be clues to constructing a more accurate picture of our galaxy.
“Because of the size of our galaxy, it’s infeasible to send a satellite up there to take a picture,” she says.
Since we are living within the Milky Way it is much harder for us to get a clear idea of what it looks like. We know that the Milky Way is a spiral galaxy, but we don’t yet know how many “arms” the spiral has and if it’s even a well-defined spiral.
These kinds of celestial mysteries have long fascinated Battersby.
Battersby says she would “devour” astronomy books and magazines her parents gave her, but it wasn’t until college that her passion truly developed.
She did her Ph.D. thesis at the University of Colorado on high-mass stars being formed on the disk of our galaxy. During this research she made an astounding discovery that every high-density cloud in space is already in some phase of forming a star, a process that takes millions of years.
This led her to conclude that star formation starts as the cloud is collapsing bit by bit, modifying previous ideas of the timeline of this process.
“If you look at something new in a way no one’s looked at it before, the universe has a great way of surprising us,” Battersby says.
In August 2018, Professor Barrett Wells entered as the new head of the Physics department, following Professor Nora Berrah. Barrett is an experimental condensed matter physicists with a robust research program involved in both synthesis and advanced experimentation around novel phases of quantum materials. Barrett brings to the department strong administrative talent, having served a long term as the associate department head for undergraduate affairs as well as chairing many important committees since his arrival at UConn.

Connor Occhialini – Finalist 2018 LeRoy Apker Undergraduate Achievements Award
by Jason Hancock
One of our star undergraduates, Connor Occhialini, has won national recognition as a finalist in the 2018 LeRoy Apker Undergraduate Achievements Award competition for his research in the UConn Physics department. The honor and distinction is awarded not only for the excellent research achievements of the student, but also for the department that provides the supportive environment and opportunities for students to excel in research. Connor is in fact the second Apker finalist in three years’ time (Michael Cantara was a 2016 Apker finalist). Connor graduated with a BS in Physics from UConn in May 2018 and stayed on as a researcher during summer 2018. During his time here, he developed theoretical models, helped build a pump-probe laser system, and carried out advanced analysis of X-ray scattering data which revealed a new context for an unusual phenomenon – negative thermal expansion. With these outstanding achievements, the department presented Connor’s nomination to the 2018 LeRoy Apker award committee of the American Physical Society. Connor was selected to be one of only four Apker finalists from all PhD-granting institutions in the US. With this prestigious honor, the department receives a plaque and a $1000 award to support undergraduate research. Connor is now a PhD student in the Physics Department at MIT.
The Katzenstein Distinguished Lectures series continued in the 2018 academic year with its twenty second Nobel Laureate lecturer, with an October 26, 2018 lecture by Professor Rainer Weiss of the Massachusetts Institute of Technology.
The title of Professor Weiss’ talk was “Exploration of the Universe with Gravitational Waves”, with abstract:
The observations of gravitational waves from the merger of binary black holes and from a binary neutron star coalescence followed by a set of astronomical measurements is an example of investigating the universe by “multi-messenger” astronomy. Gravitational waves will allow us to observe phenomena we already know in new ways as well as to test General Relativity in the limit of strong gravitational interactions – the dynamics of massive bodies traveling at relativistic speeds in a highly curved space-time. Since the gravitational waves are due to accelerating masses while electromagnetic waves are caused by accelerating charges, it is reasonable to expect new classes of sources to be detected by gravitational waves as well. The lecture will start with some basic concepts of gravitational waves, briefly describe the instruments and the methods for data analysis that enable the measurement of gravitational wave strains of one part in 10 to the 21, and then present the results of recent runs. The lecture will end with a vision for the future of gravitational wave astrophysics and astronomy.
In 2017 Professor Weiss shared the Nobel Prize in Physics with Professor Kip Thorne and Professor Barry Barishfor their epochal discovery of gravitational waves, waves that had been predicted by Albert Einstein using his General Theory of Relativity no less than a hundred years before.
Professor Rainer Weiss received his BS degree from MIT in 1955 and his PhD from MIT in 1962. He was on the faculty of Tufts University from 1960 to 1962, and did post-doctoral research at Princeton from 1962 to 1964. He joined the MIT faculty in 1964 and remained a regular faculty member there until he became emeritus in 2001. Along with Kip Thorne, the late Ronald Drever and Barry Barish he spearheaded the development of LIGO, the Laser Interferometer Gravitational-Wave Observatory, a set of two interferometers, one located in Louisiana and the other in Washington State. The interferometers would jointly look for gravitational wave signals seen in coincidence, and in September 2015 made the very first detection of gravity waves. At Louisiana State University he has served as an Adjunct Professor of Physics since 2001. As well as research in gravity waves Professor Weiss’ other primary interests are in atomic clocks and cosmic microwave background measurements.
Dr. Weiss had previously visited the University of Connecticut in Fall 2015 as part of a lecture series that fall given at the University of Connecticut in commemoration of the hundredth year of Einstein’s development of his Theory of General Relativity. At that time Dr. Weiss described the ongoing search at LIGO for gravity waves produced by the merger of two black holes. And the initial announcement of a discovery was made in February 2016, shortly after Dr. Weiss’s visit to the University of Connecticut. It is also of interest to note that Dr. ShepDoeleman of Harvard University was another of the speakers at the Fall 2015 University of Connecticut Einstein commemoration. He talked about the ongoing effort to actually detect the event horizons associated with black holes using the Event Horizon Telescope, black holes being yet another prediction of Einstein’s Theory that was also one hundred years old. And in 2019 Dr. Doeleman announced the very the first direct detection of a black hole event horizon. Thus, with the first detection of gravity waves produced by black hole mergers and then the detection of an event horizon itself, the theory of black holes is put on a very secure observational foundation.
