The course webpage provides updated information about assignments, readings, schedule changes, upcoming events, course policies, etc.  There is also a collection of biophysics-related web links.  I will assume that you are visiting the webpage regularly and reading the announcements posted there.

Course objectives:

This course aims to introduce the physical principles that underly a variety of important biological and biophysical phenomena, as well as a number of valuable laboratory techniques and probes.  The course combines physical and biological perspectives in order to explore a wide range of topics in a way that is not usually possible in standard undergraduate physical- or biological-science courses.  The presentation is aimed at the undergraduate level and is designed to be suitable for both bio-oriented and physics-oriented students. 

The course also emphasizes scientific writing and communication.  Through papers and presentations, students can further explore the specific areas of biophysics that they find most interesting.  The course satisfies a Gordon Rule communications requirement:  the student will receive credit for 2000 words of writing if the course is completed with a letter grade of C or higher. 

Topics covered:

The course will begin with an overview of biophysical research, its definition, and objectives.  We will then investigate some of the applications of dimensionless numbers and scaling laws in biology, including the famous Kleiber’s law.  Then we will introduce some aspects of molecular biophysics;  we will briefly review protein and nucleic acid structure, and then explore some simple polymer-physical approaches to the study of biomolecules, and learn some of the physics behind important technologies for DNA separation and electrophoresis.  We will discuss the application of NMR and x-ray crystallographic techniques to studies of biomolecular structure and dynamics.  We will then discuss the physics of biological motility, including the hydrodynamics of bacterial motion, the operation of the bacterial flagellar motor, and other biomolecular motors.  Finally, we will discuss the interactions of biological systems with electromagnetism.  This will begin with an analysis of the physics of vision and the eye, and continue into a discussion of rhodopsin and neural signalling.  As time permits, this may lead to discussions of some simple physical models for neurons and neural processing.

Textbook:

This course will draw from a variety of sources, since no one textbook covers all topics satisfactorily at the appropriate level.  However, students may find the following books useful; these are recommended but not required.  You may already own textbooks that cover similar topics, or you may benefit from books at a different level than these:  Therefore, you are strongly advised to consult with the instructor before purchasing any text.

Grading:

The final grade will be based on

30%     Term paper (2500 words, or about 10 pages)

15%            Classroom presentation on the topic of the paper

15%            Occasional short assignments & homework

25%            Final examination

15%            Class participation and discussion

100%            Total

The term paper forms an important part of the course:  it is the student’s opportunity to develop and present his/her own interdisciplinary perspective on an contemporary scientific research problem.  Students will have broad freedom to select topics that reflect their own interests, although the goal should be to choose a topic that represents (as nearly as possible) a 50/50 mix of biological and physical science.  The final choice of topic must be approved by the instructor.  Each student will write an initial draft, which will be carefully reviewed by the instructor and returned with detailed written comments.  These comments – and the grades on the final version – will reflect the suitability of the topic, the level of presentation, the conceptual organization and structure, the adequacy of referencing and bibliographic detail, and the overall adherence to standards of good written communication.

Academic honesty policy:

Students are expected to hold themselves to a high standard of academic honesty.  While completing the registration form at the University of Florida, every student has signed the following statement: "I understand that the University of Florida expects its students to be honest in all their academic work. I agree to adhere to this commitment to academic honesty and understand that my failure to comply with this commitment may result in disciplinary action up to and including expulsion from the University." 

Class attendance:

Class participation includes regular attendance and is definitely expected.   Students who anticipate difficulty in attending class regularly should contact the instructor in advance.

Make-up of exams and assignments:

Students requesting make-ups or other such accomodations must contact the instructor as soon as reasonably possible once the need arises.    

Students with disabilities:

Students requesting classroom accommodation must first register with the Dean of Students Office.  The Dean of Students Office will provide documentation to the student who must then provide this documentation to the instructor when requesting accommodation.
