Sight-reading a Cosmic Symphony in Gravitational Waves by Dr. Alex Urban

The era of multi-messenger astronomy is upon us. In the last few years, the LIGO observatories in Hanford, WA, and Livingston, LA have made it possible to witness cacophonous mergers of black holes and neutron stars, then call out to other telescopes around the world and in deep space, all in nearly real-time. But how can we tell so quickly what is happening out in the cosmos, just by staring at some convoluted data? The answer, surprisingly, can be understood through audio engineering — and the power of music. In this seminar we will explore connections between merging black holes and the physics of artful sound, examining what the pitch, timbre, intensity, and tempo of musical instruments can teach us about how to interpret this brand-new field of gravitational wave astronomy.

Join us for this presentation by Dr. Alex Urban on Wednesday, 6 November 2019 @ 12:30 pm in Carr 122

Allegheny College to Host One-Day Women in Physics Conference

With the goal of boosting women’s prominence in the field of physics, Allegheny College will host a free Women in Physics conference on Saturday, November 9, in Carr Hall. The event starts with registration at 8:30 a.m. and concludes at 7 p.m. The day will include poster presentations, a career panel discussion, and a seminar on negotiating professional positions and sharpening communication skills.

“Seventy-three percent of all physicists are men,” says Adele Poynor, assistant professor of physics at Allegheny. “This is a chance to get women together, build a community, and inspire and support one another.”

The conference organizers — who include Poynor and senior Allegheny students Grace Rohaley, Olivia Krieger, Anna Campbell Sowden, Juliana Sebolt and Sarah Seitanakis — hope to attract dozens of women from the Ohio-New York-Pennsylvania region, ranging from high school students, current undergraduate physics majors, and women who already work in the industry.

“Those in attendance will also have the opportunity to network with other fellow physicists as well as many leaders in academia and industry in an environment where all can share their experiences, advice and ideas,” Poynor says. “There are lots of jobs in physics; not everyone becomes a college professor.”

The keynote address will be delivered by Carolyn Kuranz, associate research professor at the Center for Laser Experimental Astrophysical Research in Michigan. Also speaking will be Kristi Caldwell, a physics teacher in the Palmyra-Macedon School District in New York; Caitlyn Neidig, a 2012 Allegheny graduate who is an engineer at PPG Industries; Barbara Dunlap, a 2009 Allegheny graduate who is a senior research associate at the Ohio State University Department of Chemistry/Biochemistry, and Brianne Hitchner, a 2014 Allegheny graduate and a signal processing engineer at Lockheed Martin.

The two-hour seminar on mastering negotiation and communication skills starts at 1 p.m. Participants will learn how to negotiate a graduate, postdoctoral or professional position in academia, industry or a national laboratory; interact positively on teams or with a mentor; think tactically; enhance personal presence; develop alliances, and achieve professional goals. It is possible to register for, and attend, just this seminar, Poynor says.

This will mark the second Women in Physics conference at Allegheny. “We did it in 2017, and the students created the entire program. We had about 30 attendees from seven schools and some high school students. The goal is for the conference to travel around the region. We’re hoping more schools will take it up,” Poynor says.

The conference is sponsored by the National Science Foundation, the American Physical Society, and the Barbara Lotze Endowed Lectureship Fund. Those interested can register online for the conference here. Registrations are due Thursday, Oct. 31.

Eclipse Draws Gators’ Gaze Skyward

The sky grew darker, the temperature cooled, and Allegheny College students looked skyward.

“It’s amazing to see,” said Taylor Cook, 18, a first-year student from Mt. Orab, Ohio, who is planning to major in art and technology.

Meadville, Pennsylvania — like the rest of the state — wasn’t in the path of totality for Monday’s total solar eclipse, the first total solar eclipse in the contiguous United States since 1979.

But that didn’t matter to the roughly 100 students, faculty and staff who gathered on the lawn outside Allegheny’s Newton Observatory. Looking through special eclipse glasses, pinhole cameras and telescopes, they were treated to a partial eclipse that blocked out about 77 percent of the sun.

The group included Allegheny President James H. Mullen, Jr., Provost and Dean of the College Ron Cole and more than 40 students involved in the Access Allegheny Scholars Program, a program designed to improve the first-year college experience of traditionally underrepresented or underserved students, including, but not limited to, first-generation college students and students who come to Allegheny from a great distance.

“It’s a great initial experience for them, being a part of a national experience while here at Allegheny,” said Rachel O’Brien, associate professor of geology and dance studies.

Outside on the lawn, students passed around glasses and gathered around a Sunspotter, a special telescope that projects an image of the eclipse onto white paper for safe viewing. Inside the observatory, Associate Professor of Physics Jamie Lombardi gave visitors a quick tutorial on the workings of its 9.5-inch refracting telescope. The telescope is more than 100 years old and is outfitted with a mirror on the end that blocks almost all of the sun’s light.

“That’s crucially important,” Lombardi said. “If it didn’t have that, you could literally blind yourself.”

The eclipse is the kind of special event that can help ignite a person’s interest in science, Lombardi said.

“People have been interested in this kind of thing for hundreds, thousands of years,” he said. “Everyone, regardless of age, has a connection to the universe and a curiosity about the universe.”

Sean O’Gary, a 19-year-old first-year student who plans to major in physics, is from Chattanooga, Tennessee, inside the path of totality. He was disappointed not to see the full blackout, but still impressed by the partial eclipse and the chance to view it through the Newton Observatory telescope.

The eclipse puts our presence in the universe in perspective, O’Gary said.

“We’re just tiny people and we’re privileged to be able to think about what’s going on and understand it,” he said.

Miss the eclipse? Not to worry. Northwestern Pennsylvania will be in the path of totality for the next total solar eclipse in the United States, in April 2024.

Rigorous Academics Inspire a Career in Physics

When he enrolled at Allegheny, Colby Mangini ’04 thought he’d probably major in international studies. He had studied Spanish in high school, and international business and economics sounded interesting. He wanted a college degree but wasn’t exactly passionate about academics.

“I wasn’t challenged that much in high school and could get by doing the bare minimum, so I did,” he says.

During his first semester, Mangini decided to get his science requirement out of the way and signed up for Physics 101 with Dr. James Lombardi, Sr. As it turns out, that single introductory course would change the trajectory of Mangini’s studies, and shape his future career.

Now, a little over a decade since he graduated summa cum laude with a bachelor’s degree in physics, Mangini holds a doctorate in radiation health physics and is board certified in the field, both accomplishments that have helped fast-track his career and allowed him to play a major role in the treatment of children who are battling cancer.

In his current position as radiation safety officer at St. Jude Children’s Research Hospital in Memphis, Mangini makes sure that patients and their families, along with staff, and members of the local community are safe from the potentially damaging effects of radiation used in medical and research applications within the hospital. He also ensures radiation-emitting material does not escape into the environment and that St. Jude’s programs comply with state and federal regulations.

There are a lot of uses for radioactive materials in a hospital setting. X-rays and CT scans probably come to mind but there are also radioactive materials that are injected into patients so that doctors can capture an image of say, the thyroid gland, and radioactive materials and equipment used to treat cancers. Additionally, at a research hospital, various radioactive substances are being generated and used in laboratories.

It is Mangini’s job to be certain X-ray machines are properly shielded by lead walls. He makes sure patients with a radioactive substance in their bodies do not contaminate other patients or their family members, and that the rooms where they stayed are properly decontaminated. He must see that nothing escapes the lab setting in which it is meant to be contained.

Most hospitals have radiation safety officers, but Mangini’s role at St. Jude presents a unique challenge. St. Jude houses a revolutionary new device, the 230 MeV proton synchrotron, that uses a thin beam of protons to treat tumors. It is one of a few of its kind in the world, and the only unit dedicated solely to pediatric care.

“St. Jude’s proton accelerator uses pencil-beam technology,” explains Mangini. “If you could see the proton beam it would look like a laser pointer.” The device allows doctors to direct a stream of radiation at a tumor with great accuracy, meaning less damage to neighboring tissue and skin. It means tumors near sensitive areas of the body, such as the brainstem can be safely treated with radiation. Less damage to healthy tissues means less recovery time for patients. It also improves outcomes down the road, with fewer patients experiencing recurring or secondary cancers related to radiation treatment.

“When protons hit the patient, it creates a secondary radiation field comprised of neutrons and gamma rays,” Mangini says. “The protons stop at the patient—they destroy the cancer—but the other particles don’t.”

That is where Mangini and his team come in. They make sure the rooms housing the proton beam technology have the proper amount of shielding in the walls and that the secondary radiation is not escaping into the hallway or waiting area where a patient’s family is sitting. They make sure the people working on the floor above the Proton Therapy Center aren’t exposed, and that appropriate staff wear personal dosimeters, which monitor their exposure to radiation.

Mangini also helps to educate St. Jude employees whose work takes them into the proton facility. “People fear radiation,” he says, “because they don’t know a lot about it. I spend a lot of my time communicating to staff members about what is happening inside the proton facility, what they could be exposed to, and what we have in place—the shielding, and safety systems.”

It is a big job with an endless list of responsibilities, which, for Mangini, is both the challenge and the reward. “What they are doing here at St. Jude is cutting edge. If something I do falls by the wayside or I don’t do something correctly or something happens to the safety systems or there’s a regulatory issue, all that work could come to a stop. It increases the importance of everything we do.”

A Student Motivated by Challenges

In order to jump from Physics 101, a course intended for non-majors, into the curriculum for physics majors, Mangini had to get a waiver. He first sought the advice of physics professor Doros Petasis. Mangini left that conversation feeling that the transition into the major would be doable but difficult. “I saw this as a challenge and always remembered that feeling,” says Mangini, who received the waiver. “I was determined to be the top student in every physics class thereafter.”

“Allegheny was a huge step up from high school,” Mangini says. “When it started to become clear—what I could achieve in college, I had more motivation. I was challenged and applied myself a lot more.”

Mangini says he discovered, while in college, that he is motivated by setting personal goals for himself, which meant, at Allegheny, GPA goals. After college, his goal was to become an officer in the Navy. Mangini realized that this pursuit could also fulfill another of his goals: to explore the love of teaching he developed while he was a physics tutor at Allegheny. Eventually, he became a senior instructor and lieutenant in the Navy.

Teaching in the Navy had its own set of motivating challenges. At first, Mangini wasn’t teaching physics, but nuclear and mechanical engineering, which meant, he had to teach himself the material before he could teach it to his classes. “I had to learn everything involved with how a reactor core takes nuclear fuel and causes a propeller to rotate at the back of a boat,” he says. Mangini again rose to the challenge and excelled. He was awarded “Master Training Specialist” designation by the Navy.

After completing his four-year term in the Navy, while simultaneously earning a master’s degree in health physics from Oregon State University via distance education (he was stationed in South Carolina), Mangini decided to take Petasis’ advice. He and his wife, Kyla Vandree ’04 Mangini moved to Corvallis, Oregon, and he enrolled in Oregon State’s doctorate program.

While there, Colby reworked the code for VARSKIN, a computer program that helps to estimate the amount of biological damage received by skin when it comes into contact with radioactive material. VARSKIN’s ability to produce an accurate estimation was poor under certain conditions. Mangini spent many nights awake in bed thinking over the problem. He had to figure out where the weakness was in the code, then how to write a better code.

“I developed a new physics model that could be used to more accurately estimate the biological damage from high energy electrons,” he says. “I incorporated that model into the computer code itself, so the latest version of that code uses my model. I still consult and trouble-shoot that code.”

Throughout Mangini’s academic career, Professor Petasis has continued to inspire him to excel. The professor’s initial hesitation about Mangini’s promise as a physics student quickly changed to enthusiasm. He “took me under his wing,” says Mangini. Petasis encouraged him to do undergraduate research and to pursue an academic career in physics. “Him having that belief in me, that I was capable of a Ph.D., was always in the back of my mind as my career progressed.”
