I really liked this article in Physics Today about how animals sense magnetic fields. I had no idea that (a) so many different kinds of animals can do it, or (b) so little is known about how they do it.
I am an associate professor of physics at the University of Richmond. In addition to teaching a variety of undergraduate physics courses, I work on a variety of research projects in cosmology, the study of the origin, structure, and evolution of the Universe. University of Richmond undergraduates are involved in all aspects of this research. If you want to know more about my research, ask me! View all posts by Ted Bunn
