Unformatted text preview: APh161: Physical Biology of the Cell Homework 2 Due Date: Thursday, January 21, 2010 “Twenty years from now you will be more disappointed by the things you didn’t do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the tradewinds in your sails. Ex- plore...dream...discover.” Mark Twain Comments from RP to Class: This second homework continues with the theme of developing a feeling for the numbers in biology and supplements that with using the Boltzmann distribution and the physics of random walks to understand some biological processes. Referee report: Read the second set of vignettes from the new book that I am writing with Ron Milo entitled “Cell Biology By the Numbers” that are posted on the course website associated with this homework and write a referee report on each one. Note that on the first homework some of you did an exquisite job while some small fraction of you gave reports that were at best cursory. I would encourage you to try something more thoughtful. Also, we have included a first cut at a “preface” that is intended to give you some sense of what the book is about. Read that as background for your reading of the remaining vignettes and provide any input you have on this first very casual attempt at a preface. As last time, the report should focus on the following questions: Does the overall logic make sense? That is, is the point of the vignette clear and does the organization work in making this point? What suggestions do you have to make it more readable, clear and interesting? Did it teach you anything new? What would you suggest should be removed? Try to find extra biological numbers pertinent to the vignette. Bonus: join the community effort and contribute these numbers at www.BioNumbers.org Please E-mail the report, as a Word or PDF file, to me ([email protected]), Stephanie Johnson ([email protected]) and my coauthor Ron ([email protected]) on the day the homework is due....
