Bio322: Biophysics (Introduction to Physical Biology)

[ver. 2015]

Physical biology of molecules, cells and tissues at equilibrium. Biophysical techniques.

This course will focus on developing concepts to leverage the power of physics to unravel problems in biology at the cellular scale. We build on standard results in classical mechanics (springs, rods, pendula etc.) for biological insight. From this we introduce statistical mechanics as a means of dealing with biological complexity at the molecular and cellular scale. We intersperse this with a constant discussion of the number-scales and experimental techniques used to test these theoretical pradigms.

Scores will be scaled as y = e x / 3 , (i.e. y= exp(-x/3)), where x=delay in days after date of submission, and y=score.

Policy on plagiarism [pdf]: A document of what is acceptable usage of existing resources. It particularly deals with what IS and IS NOT acceptable use of published, online, wikipedia, journal-article and other sources of information, figures, graphs and words. It is mandatory for all course attendees to have read it. A quiz will be conducted on your understanding.


Lecture notes [password protected]. A mixture of lecture-slides and summaries of the material covered. Please do not treat these as a replacement for (a) attending the class and (b) reading on your own.
