| Abstract | 
We will apply simple yet powerful
ideas of physics to gain some understanding of biology. (What is the
inertia of a bacteria and how does this affect its behavior?) We will
begin with atoms, move to molecules, then macromolecules, then cells,
and finally whole systems. For example, how do we see? The answer:
photons cause the release of chemicals that create electricity. How do
we move? The answer: tiny biomolecular motors break chemical bonds,
using the energy to create force and motion with efficiencies that put
man-made machines to shame. These motors, and indeed, much of biology
at the molecular level, operate at the nanometer (one-billionth of a
meter) and picoNewton (1 trillionth of a pound) scales. How can we
measure such tiny things? Come find out! No prior biology knowledge or prerequisites, since the course includes a molecular biology primer.
