The American Journal of Physics

What is my favorite physics journal? Undoubtedly it is the American Journal of Physics. Russ Hobbie and I cite many AJP papers in the 4th edition of Intermediate Physics for Medicine and Biology. In fact, Russ has published over a dozen items in that most wonderful of journals. (I’m still looking for an opportunity to publish something there.) What is my favorite AJP paper of all time? That would be Edward Purcell’s “Life at Low Reynolds Number” (Volume 45, Pages 3–11, 1977). I hand out copies of this paper to my students whenever I teach Chapter 1 of our book, where we discuss the Reynolds number and its role in biology and medicine.
