Physics, loosely defined as the pursuit of the fundamental laws that govern nature, is one among a
handful of foundation stones, upon which modern chemists, biologists and applied scientists
(including engineers and physicians) build their understanding and their professional lives. That
explains, in part, why professional accrediting organizations in engineering (ABET) {What is
ABET and What does it have to do with physics?}, chemistry (ACS) and medicine (AMA) require
at least one year of rigorous instruction in the foundations of physics. This course is the first
semester of a two semester sequence which satisfies the minimal physics requirements for IWU
students majoring in chemistry and biology, IWU students in the pre-med, pre-vet and pre-dental
programs, but not for students majoring in physics or those who are in the pre-engineering
program.
●
An intellectually deep engagement with physics, even over a span as short as two semesters, is
capable of providing such an expansive and integrated understanding of so many aspects of the
natural world that physicists can be forgiven for sometimes describing their discipline in
hyperbolic terms like “knowing the mind of God.” (The Mind of God, Really?) It is my hope that
you will give yourself the opportunity to countenance the depth, breadth and beauty of physics and
its close and deep connections with chemistry and biology.

Physics textbook authors and instructors often disagree, sometimes violently, over the proper
content, and also the proper order of this content, for a class of this type. To make matters more
complex, we are in the middle of an ongoing national conversation about the proper role of
physics in the preparation of physicians. Prof. Bunn's Blog on Pre-med physics
For authors, one of the challenges has been to strike the right balance between what are the
foundational/fundamental physics concepts and skills, on one hand, and examples and applications
that are drawn from the life-sciences and chemistry, on the other hand, and to do this while
recognizing the fixed duration of a semester, and keeping the mathematics requirement
manageable. Given this situation, I tried out (last year) a NEW textbook – it was developed by a biophysicist,
sponsored by NSF funding, and had been designed explicitly for life-science students.
Unfortunately, the second half of that textbook (Phys 102 in spring semester) turned out to be
quite poor, and some students disliked that book a lot. So, this year, we have reverted to a
textbook that has been thoroughly tested, and has been in widespread use, for over a decade, at
some of the best universities. Grading: ●

25% of your overall grade will be determined by the lab component (you will get details from your lab instructor) The remaining 75% of your overall grade will be determined by the lecture component of the course I will evaluate this component, and it will be broken down as follows 10%: homework. 10%: quizzes 40%: four in-­‐class exams (10% each) 15%: final exam Tentative Schedule

Over the course of the semester, we will study Chapter 16 – 30 of the textbook. We will
omit certain sections, and I will draw attention to those as we go along.
I will also bring in substantial supplemental materials for the following topics in Medical
Physics:
Diagnostic Medical Imaging: Ultrasound, X-ray, Nuclear Imaging (SPECT, MRI, CT,
radioactive Iodine and other kinds of imaging, PET)
Nuclear Medicine Therapies (Gamma knife, hyperthyroidism, thyroid cancer,
neuroendocrine tumors)
