Page Proofs

This week is a major anniversary for the fourth edition of Intermediate Physics for Medicine and Biology. One year ago this Tuesday, the page proofs arrived. Russ Hobbie and I painstakingly checked 632 pages of text, figures, tables, and equations, equations, equations (I estimate about 2000 of them). The job took over our lives for two weeks, but we finished before Thanksgiving, bringing to an end the process of preparing the 4th edition that had begun five years earlier.
