We make a special effort to complement the algebra-based,
introductory physics course targeted for students in life
sciences (PHYS 135) with reading materials and problems relevant
to biological and medical fields. The objectives are to relate
important concepts in physics to living systems, with particular
emphasis on applications in biology and medicine.

Students particularly praise a physics perspective on
biological applications that they may have already seen in their
other classes. For example, while covering topics in
electricity, we spend two full lectures discussing a physical
model for propagation of electric potentials in axons.
Many students are familiar with nerve functions from their
classes in neuroscience and find the physics perspective
complementing their understanding.

operation of ECG was purchased from
Ramsey Electronics. |
The in-class demonstrations are also geared toward
bio-medical applications. A favorite demo is the operation
of the electrocardiogram (ECG) monitor, where students observe
electric potentials on the skin of a human body in action.
We supplement the standard physics text with reading
materials that further integrate concepts of physics into ideas
in biology and medicine. After reading the supplements,
students are asked to write short essays on topics such as
computerized x-ray tomography, magnetic resonance imaging,
treatment of foods by gamma radiation etc.
