The Gauss Gun

AND THEN…they pulled out the Gauss Gun. And we, teachers and scholars alike, were all blown away. You get some neodymium magnets, a few ball bearings, and a groove on which the ball bearings can roll. A single ball bearing (from the left) is given a gentle push toward the magnet. As the single ball approaches the magnet, it feels the magnetic attraction, gets pulled in, and suddenly…the rightmost of three balls on the opposite side ROCKETS away with unexpected velocity (usually causing first-timers to jump in surprise).

The Physics Alive Kingfisher

The kingfisher is one of the classic examples highlighted in biomimicry. This link between birds and biomimicry is what first drew me to the possibility. Birds also exemplify so much delightful physics, including flight, bone and feather structure, color produced by diffraction and wave interference, and the streamlined beak. But the bird also serves as a metaphor. […]

Inspired by Fellow Physics Educators

What has been true again and again with the Physics Alive interviews, is that the teachers in the physics community are gosh darn awesome. We share this kinship, of common mission, common passion. After every single interview I’ve finished, I’ve felt energized, motivated, and inspired. I love learning new things, sharing ideas, gaining new perspectives. For all of the teachers and education researchers out there, I hope you find inspiration, energy, ideas, and a new spark with each episode of Physics Alive.

Zoom Synchronous? No thank you!

The first big question when planning for a course during a COVID-semester: Should my Zoom lecture be synchronous or asynchronous? My answer came quickly. No. No thank you. Wait, no to Zoom synchronous or no to Zoom asynchronous? No to ZOOM…period! Synchronous Zoom is a great way to keep the lecture-style of teaching alive. Trouble is…I want it dead.
