On Friday March 9th, the OSU Astronomy Club and the Department of physics held the first Astronomy Open House of 2018! The Astronomy Club under Emily Simpson, Rachel Hausmann, Samantha Carrothers, Nathanial Miller, Leon Linebarger, Tyler Parsotan and many dedicated volunteers invited OSU students, adults and children to Weniger Hall to have fun with hands on demonstrations that help explain how astrophysical phenomena work.

Emily Simpson helps attendees determine which scientist they are most like.

Some of the activities included a room dedicated to Mars landing sites, by Rachel Hausmann, an activity dedicated to the mythology behind constellations, by Samantha Carrothers, a test created by Emily Simpson to determine which historical scientist you would be. We also had a presentation on remote telescope observations by local astronomers Tom Carrico, a presentation on telescope tuning by Stephen McGettigan, and the OSU Robotics Club show off their Mars rover!

Astronomy Tom captivated the attendees with how easy it is to get amazing astronomy photographs.

Over 100 people attended the event and got a free NASA poster for completing each activity! While we weren’t able to have telescopes out for this event due to the weather, future events will have night observations; especially as the weather gets better and better here in Oregon. In order to hear about our next event like us on facebook.com/osuastronights. We hope to see you there!

Undergraduate volunteers from the Department of Physics took some of their favorite kid-friendly demonstrations to share with families at the annual Family Science Night at Franklin School, Corvallis, on January 25th. The demonstrations included exploding balloons in a vacuum chamber, the dielectric breakdown of air, target practice with a vortex cannon, rainbow effects with diffraction glasses and the department’s home made hover craft.  Many thanks to volunteers, Zack Colbert, Lincoln Worley, Mirek Brandt, Garrett Jepson, Hanna Hansen, and Mattia Carbonaro.

The work of OSU physics graduate student Lee Aspitarte was featured as a Scientific Highlight on the American Institute of Physics website. Lee’s recent experiments in Ethan Minot’s lab provide new insights about nanoscale pn-junctions. Nanoscale pn-junctions are a promising technology for maximizing the efficiency of light-to-electricity conversion.


This year’s winner of the WIC Culture of Writing Award in Physics is Jeremy Meinke, for his thesis entitled, “Single-Molecule Analysis of a Novel Kinesin Motor Protein.” Jeremy worked under the direction of Prof. Weihong Qiu.  He was with the Qiu research group for two years and in 2016, he received URISC and SURE awards to support his work. Jeremy says of the OSU Physics Department, “I enjoyed the range of physics topics the upper division classes offered, which kept me constantly thinking about new concepts.  Overall, it was a great place for me to study physics. I truly benefited from the research experience.”

Physics graduate student Carly Fengel shows a Timber Ridge Elementary School student the beautiful spectral lines of hydrogen, helium, argon and neon lamps. When viewed through diffraction grating glasses, the various wavelengths of light are split apart, revealing a unique signature for each gas. “So we could tell what stars are made of!” remarked the student.

Family Science Nights have been a yearly staple in Corvallis schools for more than a decade, but May 16 was only the second one for Timber Ridge School, a combined middle and elementary school serving a rural area on the northern edge of Albany. About 200 students of all ages attended the event, with middle-school students acting as guides and selling snacks as a fundraiser.

In addition to volunteers from the physics department, OSU was represented by other departments, including the College of Veterinary Medicine, the College of Earth, Ocean, and Atmospheric Sciences, and the School of Nuclear Science and Engineering. Non-departmental groups also showed up, such as the Dairy Club, Geology Club, and Fisheries and Wildlife Club. For the first time, nursing students from Linn-Benton Community College made an appearance, rounding out the science offerings with tables focusing on exercise, vital signs, CPR, and hand-washing.

Other physics demos included classics like levitating ping-pong balls with a hair dryer and the ever-popular hovercraft. As usual, the line for the hovercraft rarely dropped below a dozen students, continuing to draw a crowd to the end of the hall throughout the evening. Many were eager to learn how the hovercraft worked and several times kids remarked: “I want to make one!”

(Prof. Ethan Minot explains the design of the hovercraft)

As the last Family Science Night of the school year, this event ended the semester on a high note, with several new groups and a new physics demonstration. Both volunteers and families will be looking forward to next year’s school outreach events.

A big thank you to the physics student volunteers Evan Peters, Garrett Jepson, and Carly Fengel.
