This course will highlight a number of problems in biology where the interaction with physics has proven to be crucial to understanding the phenomena involved. The focus is on physical thinking about biological systems, rather than about accumulating biological detail, and stresses the role of quantitative analysis. For physicists, the course should be easy on the formal level, but will introduce new phenomenology; known physical concepts will appear in contexts usually not covered by standard physics curricula. The course will be mostly blackboard based. It will center around the idea that important processes of life happen at room temperatures at the level of individual microscopic objects, e.g., single molecules, single photons, yet can nevertheless generate remarkable precision and reproducibility. The primary reference is Bialek W: “Biophysics: Searching for principles”, but we will use a variety of other sources.
We will cover three topics, each lasting for approximately two weeks:
1) The role of noise in living systems,
2) Applications of statistical physics in biology,
3) Optimality and efficient representation.
Target audience: Students with quantitative backgrounds (Physics, Engineering, CS/Math) or Biology students with a strong background in physics or math, wanting to get acquainted with the concepts and problems of biophysics.
Prerequisites: Linear algebra, basic calculus, basics of statistical physics, some experience with data analysis / work in Matlab or Mathematica is a plus but not required.
The final grade will be composed of a final written exam (60%) and regular small homework problems (40%).
