We graduated 54 bachelor’s degrees, five master’s degrees, and two doctoral degrees. The American Physical Society (APS) has designated us as a “top producer” for averaging 42 BS physics degrees per year from 2010 to 2012. This ranks us 19th nationally for PhD-granting institutions. Faculty was awarded $1.3 million in new or continuing research grants and about $450,000 in beam and observing time on large facilities and other donations. Our physics teaching program continues to excel. A few years ago, the Physics Teacher Education Coalition (PhysTEC) began a recognition program called the “5+ Club.” Any program that graduated five or more physics teaching majors per year could be members. We were at the top of the list with 17 graduates. Last year, I mentioned a new endowed scholarship for physics teaching majors. Thanks to your donations, we awarded two halftuition scholarships to teaching majors. Your contributions are vital to providing teaching scholarships. In other news, we remodeled part of the old demonstration prep area (room N106 ESC) to make a new teaching area for the science teaching majors. It’s a great resource for all of our teachers. Stop by and see it when you are on campus. Last year, 252 of our 312 physics and astronomy majors participated in mentored experiences. This resulted in 40 seniors completing thesis or capstone projects, 133 students presenting at professional conferences, and 45 students co-authoring on peer-reviewed publications. I firmly believe that these experiences give our students a real competitive edge when applying for jobs and graduate school. If you have a minute, send me a note at Richard_Vanfleet@byu.edu describing how your research experiences helped you achieve your career goals. I invite you to come to Provo and see what we are doing in the department. We have special events associated with Homecoming in October and graduations in April and August and we encourage you to visit in time for those events, but we will be happy to see and visit with you at any time. One of our greatest assets to help our current students is our former students. Please consider some of the ways you can help that may go beyond the greatly appreciated financial donations. Keep us updated about internship and job opportunities within your influence. Help mentor our students by taking one to lunch or by offering to help as an adviser on a project. We and our students are interested in your stories and insights. For the upcoming academic year, your donations have funded the equivalent of 33 half-tuition semester scholarships. We ask you to continue your contributions; if you desire to donate to an endowed scholarship, please contact me or Brent Hall (801-422-4501 or brenth@byu.edu) in the college office. Thanks for your continuing support. 3 JAZMIN obby into a Turning a H when jazmin myres started at BYU in 2010, she came with a love of music and a plan to major in math. However, after taking a few physics classes, she found that physics incorporated the best of both worlds—her skills at math and her interest in music. “I ended up in the acoustics research group,” Myres said. “I worked with jet noise primarily, but they do a lot of music-related acoustics. That’s what really got me interested in physics—the combination of math solving musical problems.” Since then, Myres has been able to turn her hobby into a career. After graduating from BYU in 2014 with a degree in applied physics, she landed a job in Maryland with the Naval Air Systems Command (NAVAIR). Her time is divided between two projects. One is defense-related sonar systems design. The other is related to the acoustics of military jet noise. “I was drawn to NAVAIR because the work related directly to my research and interest in acoustics. They work on aero-acoustics and underwater acoustics, both fields which I am very interested in,” said Myres. “It is also a pleasure to work for the Department of Defense and serve our country as a civilian.” As a Sonar Systems Design Physicist, Myres develops signal processing algorithms and code to identify underwater targets, which is anything that threatens National Security. This work directly protects American troops, coasts, and interests. “It is extremely important to maintain military dominance of the seas, and sonar systems is one tool that our military uses to do that,” Myres said. Career Article by Ca milla Stimps on In her other role, she works as a team leader alongside three other young engineers to solve problems such as converting acoustical energy from jet noise into usable electric power. The work Myres does is hands-on and allows her to engage with problem solving. “It’s really fun to have a problem and be able to find a solution,” Myres said. “There’s often more than one right solution, but it’s really exciting when you have a challenge . . . and you can find an answer. It’s super rewarding for me.” During her time at BYU, Myres was able to get unique hands-on opportunities alongside her professors, even as an undergraduate. She was able to work with many professors she loved and gain experience that proved valuable in the field. “At BYU, they are really unique in allowing undergraduates to do significant research. I haven’t really seen that in any other universities,” Myres said. “Everyone is really impressed that undergraduates at BYU have such an opportunity to work directly with professors.” Because of her research experience and the internships she did, she was able to graduate in April 2014 with the job at NAVAIR already lined up and was able to start working the following August. “Physics can take you a lot of different places,” said Myres. “You’ll always be able to find a job.” BYU Physics and Astronomy was a great place for Myers to start her career. Like many graduates of the department, she deeply appreciates the investment the professors, the department, and the university made in her education. 5 ALAN BYU Alu Acoustics m Improves for Air Force nobody loves the noise that fighter jets make. That’s what Alan Wall is attempting to reduce. As an undergraduate at Utah State, Wall overheard a professor mention that 3-D holograms could be constructed from anything made of waves, including light and sound. “I was intrigued by the idea, so I did some online searching and found ‘sound images’ of vehicles and machinery,” Wall said. He went on to receive a bachelor’s in physics at Utah State University (2008) and a PhD in physics at BYU (2013). While at BYU, Wall made acoustical holograms of jets with Dr. Kent Gee. “We measured the sound field in two dimensions near a fighter jet,” Wall said. “Then we used a knowledge of the physics of sound waves to reconstruct or visualize the sound field in three dimensions.” His experience has led him to his current job at the Air Force Research Laboratory (AFRL) near Dayton, Ohio in the Battlespace Acoustics Branch. “I now support the Air Force mission to protect the hearing of its personnel and reduce community noise problems that arise near air bases,” Wall said. “I am also working to turn my acoustical holography capability into an engineering tool in order to measure and reduce noise on the next generation of aircraft engines.” Wall is thankful for the time he got to spend studying acoustics and physics at BYU, and 6 Article by Ta attributes that education to much of his success. “The classes I took prepared me with the understanding of physical principles and the ability to apply them,” Wall said. “Most every day I am using the equations I derived and memorized during my acoustics courses, as well as the data analysis techniques I learned in my PhD research.” nner Call description can convey the overwhelming feeling of standing 75 feet from an F-22 as it revs its engines from idle up through full afterburner while tied down to a thrust pad,” Wall said. “The physical effect of the sound waves blasting through your body is something I wish everyone could experience at least once, while wearing vey n o c n a c n tio . g n No descrip i l e e f g lmin e h w r e v o this Wall still studies the physics of sound and reads articles on jet noise, but he also gets to see physics in action. “I apply my understanding of sound wave phenomena to investigate how various sound sources produce sound waves, how those waves travel through the air, and how they affect the people listening to them,” he said. Even though he has worked with acoustics for many years, Wall still gets a thrill every time he works with an actual fighter aircraft. “No double hearing protection, of course.” Wall also finds it rewarding when he discovers a new way to solve a problem or investigate a physical principle of jet noise. “I get on my computer and try something, struggle with the programming a bit, and then finally it works, and I have learned something new,” Wall said. “In these moments I can’t wait to show to someone else, and share in some new physical insight.” 7 BEN t e d by c e t o r P s p o Tro physics extends far beyond the lab; it plays a key role into protecting our troops and our freedom. Ben Pratt-Ferguson, who graduated in physics with a math minor from BYU in 1992 and then a master’s degree from Vanderbilt University in 1997, has worked at Raytheon Company for 16 years. Raytheon is a technology and innovation leader specializing in defense, civil government, and cybersecurity markets throughout the world. Raytheon supports U.S. and allied troops by providing state-of-the-art electronics, mission systems integration and other capabilities in the areas of sensing. They provide command, control, communications, and intelligence systems. Raytheon also includes training for the troops on how to effectively use these high-tech tools. “We build the structure for testing and performance evaluation of the system at the software level,” Pratt-Ferguson said. “We have to build the aerodynamics and the environment around the missile. In other words, we put the missile virtually into a virtual world.” This is a world of huge g-forces, massive acceleration, high speeds, viscous drag, and frictional heating. The use of aerospace technology in the workplace was what drew Pratt-Ferguson to Raytheon. He learned about defense-related aerospace technology at BYU. He earned an Air Force ROTC scholarship and was able to take some classes to learn about missile technology in the armed services. “I’ve been interested in aerospace and defense-related items since I was young,” PrattFerguson said. “So in that sense, I had already been interested in some of the technologies that the Air Force uses.” Much of the work Pratt-Ferguson does involves technology-based problem solving. With his background in physics, he is able to work through these problems. “Solving technical problems is what I enjoy most,” Pratt-Ferguson said. “What keeps me motivated is . . . first, the challenge of solving the problem. The second is understanding the bigger picture. Why am I solving this problem? Who am I helping? The answer always points back to our war fighters.” Article by Ca 8 Physics milla Stimps on at are h t e s o h t I support tting u p , s e n i l ront f e h t n o t way. ou s ’ m r a h n si themselve GARY Reducing Th reats and P ro Article by Ta Nation thro tecting the nner Call while the nation fixated on John Glenn orbiting the earth in 1962, 11-year old Gary Stradling discovered his passion for science and a desire to make a change in the world. "I was a farm boy who was not academically inclined," Stradling said. "Going to BYU and experiencing the faculty and other students in a challenging environment that required me to study, to work hard, and to produce competent work was really important.” The connections he made and the education he earned at BYU led him along an adventurous path to his current job. Stradling currently works as chief of the Monitoring and Verification Technologies Office in the Defense Threat Reduction Agency (DTRA), which focuses on compliance with international agreements, specifically in arms control. Stradling’s interest in working with the DTRA was stemmed when he reread college level geology. "It was interesting and exciting. Much of that science was developed since I got my doctorate,” Stradling said. “I am as active in learning new stuff 10 ugh Physics now as I ever was. It's necessary in order to do this work." Stradling received his bachelor's and master's degrees in physics at BYU. He went on to get another master's and a PhD in applied science and plasma physics from the University of California, Davis, while working at the Lawrence Livermore National Laboratory Before Stradling’s current job at DTRA, he served 31 years at Los Alamos National Lab, which included two tours in the Office of the Secretary of Defense (OSD). His experiences included laser fusion research and x-ray physics, nuclear weapon testing, hyper-velocity impact studies and leading negotiations of the Open Skies Treaty implementation agreement. "Some of my colleagues criticized me for not focusing on becoming the world expert in one area of physics. They thought that's the only way you can make an impact," Stradling said. "But my interest has always been in applied physics and how you make the world better using those tools. This work requires a breadth of knowledge and experience." Although running a government office involves dealing with numerous levels of bureaucracy, Stradling still relies on his knowledge of physics to get the job done. "There is the scientific aspect of understanding the technical problems that need to be solved, finding people who have the capacity to solve the problem, and working with them to develop the solution," Stradling said. "The way that I approach a problem is to say 'what is the right way to do this based on my physics understanding and development experience?'" While he may not be the world expert in any single topic, Stradling loves where his career has taken him. He loves the diversity of science he works with, and is glad for the opportunity to make the world better. He said, "I get to make meaningful contributions to national security, do things that make a difference, and have opportunities to affect the nation's approach to some really difficult problems." ful g n i n a e m ke I get to ma ional security, do to nat s n o i t u nce. b i e r e f f i contr d a ake m t a h t s g n thi STAFF SERVICE AWARDS 2011 Scott Daniel 35 YEARS Mark Erickson 10 YEARS Wesley Lifferth 30 YEARS Wayne Peterson 35 YEARS 2012 Freeman Anderson 30 YEARS Diann Sorenson 25 YEARS 2014 Nan Ah You 40 YEARS James Adams – Steve Turley Matthew Ashby – Michael Ware Pegah Aslani – Scott Sommerfeldt Kolton Barfuss – Mark Transtrum Lawrence Barrett – Robert Davis Dallin Burton – Kate Johnson Mark Berardi – Tim Leishman Kendall Berry – Robert Davis Ty Beus – Manuel Berrondo Kade Bishop – Scott Bergeson Dane Bjork – Mark Transtrum Joshua Bodon – Tim Leishman Nathan Boyer – Robert Davis Matthew Calton – Scott Sommerfeldt 12 John Ellsworth 10 YEARS Jeff Farrer 10 YEARS Andrew Davis – Richard Vanfleet Daniel Eliason – Bryan Peterson Jacob Embley – John Colton Stephen Erickson – John Colton Alex Erikson – Scott Bergeson Nathan Eyring – Tim Leishman Derek Felli – Denise Stephens Marcus Finlinson – Richard Vanfleet James Fletcher – Michael Ware Clement Gaillard – Denise Stephens Douglas Gardner – Denise Stephens Forrest Glines – David Neilsen M.
