We Americans assume that our economic system will always scam-
per to provide us with the products we want. Special orders don’t
upset us! I want my MTV! The truth is more complicated, espe-
cially in our education system, which is paid for by the students
but controlled by the professoriate. Witness the perverse success
of the bloated science textbook. The newspapers continue to com-
pare our system unfavorably to Japanese and European education,
where depth is emphasized over breadth, but we can’t seem to cre-
ate a physics textbook that covers a manageable number of topics
for a one-year course and gives honest explanations of everything it
touches on.
The publishers try to please everybody by including every imag-
inable topic in the book, but end up pleasing nobody. There is wide
agreement among physics teachers that the traditional one-year in-
troductory textbooks cannot in fact be taught in one year. One
cannot surgically remove enough material and still gracefully nav-
igate the rest of one of these kitchen-sink textbooks. What is far
worse is that the books are so crammed with topics that nearly all
the explanation is cut out in order to keep the page count below
1100. Vital concepts like energy are introduced abruptly with an
equation, like a first-date kiss that comes before “hello.”
The movement to reform physics texts is steaming ahead, but
despite excellent books such as Hewitt’s
Conceptual Physics
for non-
science majors and Knight’s
Physics: A Contemporary Perspective
for students who know calculus, there has been a gap in physics
books for life-science majors who haven’t learned calculus or are
learning it concurrently with physics. This book is meant to fill
that gap
