Dr. John Hubisz is a visiting professor of physics at North Carolina State University. He specializes in physics education. He is particularly interested in ways of teaching physics to the general public and students in grades K-14, including examining claims of the unusual (ancient astronauts, crop circles, the Bermuda Triangle, Bigfoot, UFOs, and so on) in the light of physics principles required for their occurrence. In this speech, Hubisz discusses "Energy: What is it, and how do we promote a better understanding of it?"
