# Instructor Insights

## Course Overview

This page focuses on the course 8.592J/HST.452J Statistical Physics in Biology as it was taught by Professor Mehran Kardar and Professor Leonid Mirny in Spring 2011.

This is a graduate-level course primarily geared toward physics graduate students. The course surveys problems at the interface of statistical physics and modern biology. Homework plays an important role in this course.

## Course Outcomes

### Course Goals for Students

Two communities are served by this course. For physics graduate students not specializing in biophysics, the goal is for them to gain familiarity with topics outside their primary research area(s). For students specializing in biophysics, the goal is for them to learn tools and concepts relevant to their thesis and research.

## Instructor Insights

Below, Professor Mehran Kardar describes various aspects of how he taught 8.592J Statistical Physics in Biology.

### Using the Internet as a Key Resource for Fast-Developing Fields

Unlike core physics topics, biological knowledge is constantly changing. Rather than relying on a textbook, we relied on material on the web to present the most recent developments to the students. We particularly relied on the web for certain topics. For example, sequence comparison tools (BLAST) and protein structure characteristics were demonstrated through publicly available programs and databases. Other publicly available applets were important for demonstrating relevant concepts. Links to all these resources are available in the posted materials.

### Preparing Afresh for Each Semester

We did not rely on previously presented materials, but rather prepared each lecture fresh. The purpose of the course is to introduce diverse topics where tools/concepts from statistical physics have been used in biology. Since this is an active research area with new topics and applications introduced regularly, we tried to keep up by updating the syllabus.

To this end, the co-lecturers got together prior to the semester to make up an overall plan of organizing the topics and problem sets.

Finally, prior to each class, I reviewed the material to be posted on the web (including lecture notes) and went over the entirety of the lecture.

## Curriculum Information

### Prerequisites

- 8.333 Statistical Mechanics

### Requirements Satisfied

- Biophysics Certificate Program: Physical Sciences & Engineering requirement
- For physics graduate students outside the graduate biophysics program, this course satisfies the Breadth Subject Requirement. For those in the program, it satisfies a Specialty Subject Requirement.

### Offered

- Every other spring semester

## The Classroom

- This course was taught in a medium-sized classroom equipped with chalkboards and a projector.

## Student Information

### Breakdown by Year

Roughly 75% graduate students, 25% undergraduate juniors and seniors.

### Breakdown by Major

Mostly physics majors with some participants from Health Sciences and Technology, chemical engineering, and other departments at MIT, as well as Harvard University students.

### Typical Student Background

The primary target is graduate students in physics. It is assumed that the students are familiar with basic tools of statistical physics (e.g., probability, ensembles, partition functions, ...), but no familiarity with biology is assumed. Web links to resources describing the biological context are provided.

## How Student Time Was Spent

During an average week, students were expected to spend 12 hours on the course, roughly divided as follows:

## Lecture

3 hours per week

- Met twice a week for 1.5 hours per session
- Much of the course material was distributed through the web, and web resources were also used during class to illustrate various points.
- Class typically began with about half an hour spent on introducing a topic through web links and focusing on a conceptual or computational problem.
- The remaining hour of class was typically spent on carrying out relevant calculations on the chalkboard.

## Out of Class

9 hours per week

Homework assignments comprised 80% of the grade for this class and the final project comprised the remaining 20%, so out-of-class work was very important.

## Course Team Roles

### Lecturers (Professor Mehran Kardar and Professor Leonid Mirny)

The course was co-taught by two lecturers alternating between topics with more of a biophysics, or statistical physics, focus.

### Teaching Assistant

A teaching assistant was charged with grading the eight problem sets. There were no recitations or exercise classes.
