Michael Lubell Departs APS APS Welcomes New and Current Fellows after 22 Years of Service

Michael Lubell has stepped down from his position as director of the Ken Cole Ken Cole APS Office of Public Affairs after more than 22 years of dedicated service. During this time he brought considerable experience, passion, and original thinking to his advocacy and advisory role. His efforts contributed to noteworthy successes of the Society, and benefited physicists and science significantly. Michael put his fine writing skills to work in his “Inside the Beltway” column in APS News and he lectured widely about APS activities and science policy issues at university campuses and national laboratories. Francis Slakey, APS Associate Director of Public Affairs, will serve as Interim Director of the APS Office of Public Affairs until the search for a permanent Director is complete.

In December, APS hosted a reception in Greenbelt, Maryland, to welcome new Washington area Fellows and greet current Fellows. (Left) Nobel Laureate John Mather of NASA.

Reviews of Modern Physics Active particles in complex and crowded environments Clemens Bechinger, Roberto Di Leonardo, Hartmut Löwen, Charles Reichhardt, Giorgio Volpe, and Giovanni Volpe This article reviews both experimental and theoretical advances in the field of active matter which consists of natural and artificial objects capable of self-propulsion. Prime examples of active particles are Brownian particles, biological or manmade microscopic and nanoscopic objects, that can propel themselfes by taking up energy from their environment and converting it into directed motion. The review provides a guided tour through the basic prin- ciples and fabrication of active particles and discusses also many interesting future directions these manmade micromachines and nanomachines could take as autonomous agents for healthcare, sustainability, and security applications. doi.org/10.1103/RevModPhys.88.045006 journals.aps.org/rmp

Fellows serve one year on the staff of a senator, representative or congressional committee. They Join industry R&D leaders, entrepreneurs, and senior are afforded an opportunity to learn the legislative process and explore scientists from both academic and national labs to hear science policy issues from the lawmakers’ perspective. In turn, Fellows have about cutting edge developments and well-established the opportunity to lend scientific and technical expertise to public policy issues. projects that are already a part of your everyday life. QUALIFICATIONS include a Ph.D. or equivalent in physics or a closely related field, a strong interest in science and technology policy and, ideally, some experience in applying scientific knowledge toward the solution of societal problems. Fellows are required to be members of the APS. TERM OF APPOINTMENT is one year, beginning in September of 2017 with participation in a two week Satellite sessions on orientation sponsored by AAAS. Fellows have considerable choice in congressional assignments. TUESDAY, MARCH 15 A STIPEND is offered in addition to allowances for relocation, in-service travel, and health insurance AND premiums.

The Physics of Skateboarding: Making Science Relevant, Engaging, and Motivational By William H. Robertson

lthough I am a professor at the University of Texas at El APaso, I’m also known as Dr. Skateboard. People often ask, “Why are you Dr. Skateboard?” or “What’s up with the Dr. Skateboard thing?” So let me give you the backstory. I’ll begin with the skateboard. I have been a skateboarder now for almost 40 years. I started skateboarding when I was thirteen years old, because it was something fun to do with my friends. When I was in middle school in Richmond, Virginia, I also decided that I wanted to be a professional skateboarder. As I progressed in the sport I competed as an amateur, and this allowed me to travel up and down the East Coast and even out to California. In the 1980s, I made my living as a professional skate- boarder through endorsements and prize money while par- ticipating in contests and demonstrations, as well as traveling around the U.S. and abroad. In the late 1990s and early 2000s, I did shows at many interesting venues, including state fairs, skateparks and music festivals. Today, I continue to do demonstrations, mostly in schools. I am a skateboarder. It is part of who I am. But what about the “Dr.”? You might think that since I have been skateboarding for so long, it would make me a doctor. Well it goes a little further than that. When I was in middle school, I set some goals to try and achieve success in my education as well as my sport. Really, no one in my circle had a doctorate. One skateboarding buddy said, “Dude, I don’t know anyone with a Ph.D.” I had a dream of going to college, and that dream took me all the way to getting a Ph.D., something I never thought would happen. My persona as Dr. Skateboard became a path for me to connect with students about setting high goals in all that they do. It is a way of bringing together high achievement in your education and in what you enjoy. For me, skateboarding became the vehicle that led to my success in education. In fact, the skills I learned in skate- boarding, such as practice, creativity, discipline, persistence, and setting goals, later made me successful in school. Young people can in effect learn more when they can see practical applications in their own lives. My inspiration for choosing skateboarding to teach physics came from my work with in the street or on flat ground. Additionally, the trucks (the But you might ask, what keeps me motivated? Why is middle school students who were not interested in the topics structures that attach the wheel assemblies to the deck) on Dr. Skateboard’s Action Science my passion today?

On a skateboard, the wheels and axles help the rider part of that plan. It’s about helping boys and girls to set goals Often, students will ask their teacher, “What is the point to perform standard moves like rolling, spinning, grinding, and to achieve them in STEM.
