!Learning about biophysics
* [[What is Biophysics?|http://www.biophysics.org/education/]]<br>A one-page overview of the field of biophysics, from the educational web page of the Biophysical Society.
* [[Select topics in Biophysics|http://www.biophysics.org/education/topics.htm]]<br>A listing of major fields of research in biophysics, with links to tutorial material in the different areas. Includes information on research problems, types of biomolecules, and techniques, from the educational web page of the Biophysical Society.
!Biophysics textbooks
* //Biological Physics// by P. C. Nelson, 2004. <br> An excellent textbook aimed at physics undergraduate or graduate students who don't necessarily know much biology. The book gives biological background and introduces physics ideas such as diffusion, low Reynolds number fluid dynamics, entropic forces, and self assembly that are important in biophysics. The selection of biological problems is good.
* //Mechanics of Motor Proteins and the Cytoskeleton// by J. Howard, 2001. <br> A book aimed at both biologists and physicists. It focuses on cytoskeletal filaments - biological polymers important for cell structure - and motor proteins that move on the cytoskeletal filaments. An excellent first section on physical principles introduces basic physics and includes many estimates of forces and energies important for motor proteins. The next two sections, on the cytoskeleton and on motor proteins, contain biological background, structural information, experimental results, and biophysical models.
There are several places you can learn more about biophysics and quantitative biology research at ~CU-Boulder.
* The physics department [[Biophysics Group|http://phys.colorado.edu/research/biophysics]]
* The [[Biophysics Supergroup|http://biophysics.colorado.edu/index.php/seminars]] seminar occurs approximately once a month on a Monday evening. Local speakers discuss their research; pizza is served.
* The [[Quantitative Biology PhD program|http://biofrontiers.colorado.edu/education/iq-biology/]] promotes interdisciplinary research in quantitative biology through the [[Colorado Biofrontiers Institute|http://cimb.colorado.edu/]].
* The [[Molecular Biophysics Program|http://biophysics.colorado.edu/]] is an ~NIH-funded biophysics graduate training program. The program web page includes a list of [[faculty|http://biophysics.colorado.edu/faculty]] doing research in biophysics and information about the biophysics [[certificate program|http://biophysics.colorado.edu/certificate]] for graduate students. 
* Biophysics talks are given in many different seminar series. In addition to the Biophysics Supergroup, the seminars to watch are:
** The [[Physics colloquium|http://phys.colorado.edu/upcoming-events]], Wednesdays at 4pm in Duane ~G1B20.

!!Physics 4810/7810: Biophysics
Instructor: Meredith Betterton

The physics department will offer a biophysics course for the first time in the Fall 2009 semester. Please register if you are interested in taking this course - we need to meet the minimum enrollment for the course to be offered.

!!!Course description 
This course will give an introduction to the physics of living systems for students with a physics, engineering, or chemistry background, developing the biology background as required. Topics will focus on molecular biophysics and will include the properties of biomolecules, physics of random walks and diffusion, low-Reynolds number hydrodynamics, entropy and free energy of biomolecules, entropic forces, and biological self assembly. Selected biophysics applications will be discussed based on student interest, potentially including polymer elasticity, cooperative transitions in proteins, enzymes, molecular motors, transport across membranes, and nerve impulses.

!!!Prerequisites 
Prereqs for 4810: PHYS 2210 or instructor permission. PHYS 4230 helpful but not required. Prereqs for 7810: Undergraduate statistical mechanics or instructor permission. PHYS 7230 helpful but not required.
