Professor Knight received a Ph.D. in physics from the University of California, Berkeley and was a post-doctoral fellow at the Harvard-Smithsonian Center for Astrophysics before joining the faculty at Ohio State University. It was at Ohio State that he began to learn about the research in physics education that, many years later, led to 5 Easy Lessons: Strategies for Successful Physics Teaching and this ebook, as well as College Physics: A Strategic Approach, co-authored with Stuart Field and Brian Jones. Randy’s research interests are in the field of environmental science and laser spectroscopy. When Dr. Knight is not in front of a computer, you can find him hiking,playing the piano, sea kayaking, or spending time with his wife Sally and six cats.
