In past issues of this journal, the late H. R. Crane wrote a long series of articles under the running title of “How Things Work.” In them, Dick dealt with many questions that physics teachers asked themselves, but did not have the time to answer. This article is my attempt to work through the physics of the crystal set, which I thought I knew, but actually did not.
