This month's cover is a view through Snell's window, dolphin-style.For insights into this dramatic realization of the phenomenon, and the fascinatingly interdisciplinary study behind this image, see "The dolphin in the mirror—A familiar face?" by D. Dibble, K. Van Alstyne, J. Rohr, and S. Ridgway.
ColumnsAnd the Survey Says..., Figuring Physics, Little Gems, Astronotes, Physics Challenge for Teachers and Students, Fermi Questions, Visual Physics, and Websights.
