From the Preface to the 3rd Edition, but Russell K. Hobbie
"Between 1971 and 1973 I audited all the courses medical students take in their first two years at the University of Minnesota. I was amazed at the amount of physics I found in these courses and how little of it is discussed in the general physics course.
I found a great discrepancy between the physics in some papers in the biological research literature and what I knew to be the level of understanding of most biology majors or premed students who have taken a year of physics. It was clear that an intermediate-level physics course would help these students. It would provide the physics they need and would relate it directly to the biological problems where it is useful.
This book is the result of my having taught such a course since 1973. It is intended to serve as a text for an intermediate course taught in a physics department and taken by a variety of majors."
From its very first editions, this book has been the gold standard for clear exposition of the most important physics needed to understand medicine, biology, and medical technology. Each edition has kept the material up to date and extended the book's breathtaking reach, for example, adding a chapter on ultrasound. A physics textbook is only as good as the problems it offers, and this edition has many more than before. Many of the problems are directly relevant to medicine or biomedical research--a tremendous resource. Many books show signs that the author's main interest and expertise lies in either medicine or in physics; astonishingly, this one is authoritative across the whole spectrum.
