Course Description (from the University Catalog)

Principles from physics and chemistry are explored in the context of biological processes, especially at the molecular and cellular level. Topics covered include random walks, thermodynamics, molecular recognition, dynamic processes, optics and spectroscopy. Quantitative treatments are emphasized and computer simulation and applications are used extensively.

Course Objectives

This course is designed to help students understand and appreciate the many connections between the physical and biological sciences, and also develop their skills in quantitative problem solving. Many of the most exciting scientific advances now taking place involve the application of principles from chemistry and physics to biological problems, and students who are broadly educated in the sciences will be especially well prepared to participate in these advances. At the end of the course, students will have explored several biophysical concepts in depth and will be able to apply these concepts to new situations, using appropriate quantitative and mathematical tools.

Class Sessions

Monday, Wednesday, Friday: 9:40 - 10:30 AM
Room 2560 of the new Gardner Commons building.

No classes on: Monday, 2 Sept. (Labor Day), 7-11 October (Fall Break), Friday, 28 Nov. (Thanksgiving Break)

Regular class attendance is expected of all students. The class sessions will have a mixed lecture-discussion format, and engaged participation is essential for learning. Although notes and slides from many of the lectures will be posted on the class web site, these should not be viewed as a substitute for attending class.

Electronic Device Policy

In order to encourage student engagement and create a more effective learning environment for everyone, the use of cell phones, tablet computers or laptop computers will not be allowed during class. Cell phones may be accessed during class only in cases of emergencies. Exceptions to this policy will be made for students who need to use an electronic device as part of an approved accommodation. See the section below on Special Accommodations for information about applying for an accommodation through the Center for Disability Services.


The TurningPoint audience response system will be used to facilitate interactive learning during the lectures. The clicker responses, together with other activities, will count for 5% of the course grade. Clickers can be purchased from the University Campus Store and can be sold back to the store at the end of the semester.

Any of the following TurningPoint clicker devices should work:
  • ResponseCard NXT
  • ResponseCard RF/LCD and RF
  • QT and QT2
The QT2 and ResponseCard RF/LCD models should be available at the Campus Store.

For this class, you do not need a TurningPoint Cloud account or license, and you should not try to register your clicker through the Turning Point Cloud service, though you may need to do this for other courses.
Instead, you will need to register your clicker through an ``assignment'' on Canvas. Registering your clicker by the first lecture (Monday, 20 August) will count for 5 clicker points up front. Registering by the second lecture (Wednesday, 22 August) will count for 2 points.

Although there is a TurningPoint smart-phone app (ResponseWare), it will not be supported for this class. (See the electronic device policy above.)

Other ways to earn points

  • Group problem solving sessions. Every two weeks or so, part of the lecture time will be devoted to problem solving, with students working in groups of two or three. Points for these activities will be recorded and combined with those from the clicker responses.
  • Special homework assignments. There will be one or a few short homework assignments, in addition to the bigger ones described below. Points for these assignments will be added to the clicker points.
  • Catch out the prof! Extra clicker points will be given for finding errors in the lecture notes or the slides used class, with the number of points determined by the significance of the error (as judged by the instructor). To count for points, errors on the lecture slide have to be caught before the instructor catches them in class!

Discussion Sessions

There will be two scheduled discussion sessions per week, each led by one of the TAs. These sessions will be devoted to working on problems, especially those that are on the quizzes and exams from previous years, which are posted here. You should come to these sessions prepared to work on the problems, not merely to be told the answers!

Text Book

There is no textbook for this course, but a set of detailed lecture notes is provided online here. These notes/text are very much a work in progress, and the chapters will likely be updated during the semester.

Homework Assignments

Problem solving is a major element of this class. Approximately 6 graded problem sets will be assigned during the course of the semester. Each problem set will be graded for a total score of 50 points. Problem sets may be turned in up to 5 days late, but 10 points will be deducted from the score for each day late.

Students are encouraged to work together on the homework assignments and to use outside resources, including the internet. However, the work you turn in must be your own! Any text, graphics or computer files must be clearly distinguishable from that of other students, and other sources must be properly cited. Text from other sources must be clearly identified by quotation marks. Furthermore, extensive quotations, even with proper citation, will not be considered satisfactory answers to questions. Copying and pasting does not demonstrate mastery of the material!

If two or more students turn in work that that is identical, their action will be considered academic misconduct and appropriate sanctions will be imposed. At a minimum, the sanction will include the loss of credit for the copied work, and more severe sanctions may be imposed for more extensive infractions. (See Academic Conduct, below)

Quizzes and Exams


There will be five 25-minute quizzes, given during the lecture sessions on the following dates:
  • Friday, 30 Aug.
  • Friday, 20 Sept.
  • Friday, 25 Oct.
  • Friday, 8 Nov.
  • Monday, 22 Nov.
Each quiz will cover the class material presented since the previous quiz (or mid-term exam). The lowest quiz score will be dropped in calculating the final grade.

Mid-term exam

There will be one mid-term exam, on Friday, 4 October. This exam will cover all of the material previously presented in class.

Final exam

A final exam will be given during the regularly-scheduled 2-hour exam period: 8:00-10:00 AM, Thursday, 12 December. This exam will be cumulative, covering everything from the semester.

The schedule for quizzes and the mid-term exam is subject to change. The date of the final exam is not!


The final numerical grade for the class will be based on the homework, quiz and exam scores, weighted as follows:
  • Clicker responses and other activities: 5%
  • Homework: 30%
  • Quizzes: 30%
  • Mid-term exam: 15%
  • Final exam:20%
The following represent maximum cutoffs for determining class letter grades:
  • A: 92-100% (including A-)
  • B: 82-91% (including B- and B+)
  • C: 70-81% (including C- and C+)
  • D: 60-69%
  • E: < 60%
Depending on how things go, the grade cutoffs may be revised downwards, i.e. to make the grading more generous. The cutoffs will not be moved upwards to make the grading less generous.
