Bioelectricity: A Quantitative Approach
Roger Coke Barr
Nerves, the heart, and the brain are electrical. How do these things work? This course presents fundamental principles, described quantitatively.
Announcements
Doing great, and 2 items to come.
You all are doing great! You have moved quickly into the videos and quizzes, more quickly and more intensely than I expected. I love the reading your comments on the discussion forums. I read all of them and enjoy --- or at least learn from -- every one, even though I mostly do not respond.
We are still finishing up some parts of the course organization, and I wanted you to know about two items that will be available to you soon. (1) The first is the scoring plan (how individual scores will be weighted and added). That's taken a little longer than expected because it has to be ok as to concept (me) and ok as to doing it (Coursera system). We will have it for you soon, and I think you will find that it is fine. (2) The second item soon to come is adding a section on "Hints & Kinks" where I will give some hints on the quiz questions, for those who would like them (hints), and identify places in the videos or questions where we discover small glitches (kinks). I'll put in there some notes on how one thing connects to another in ways you may have overlooked. There are a lot of strong but not-so-obvious connections :)
This course is an exciting adventure for me and no doubt for you too. I've taught courses for a long time, but never anything quite like this one :)

Course Wiki now open & New Week 1 Slides!
Hello all,
The Course Wiki for Bioelectricity is now open, at the request of some students! Please note that information posted on the Course Wiki will not be curated or monitored for accuracy and correctness by Professor Barr or myself. Enjoy Wiki-ing!
Also, the Week 1 slides have now been updated to reflect the slides used in the lecture videos. Sorry for the confusion!

Note on precision for quiz answers
For all quiz questions (in this week and others) requiring numerical answers, the required precision for full credit is +/- 1% of the correct exact answer. Hope this clears up everybody's questions!
