Extra Credit Possibilities

(1) Find some application of physical ideas, perhaps in anatomy, energy production or consumption, public health, medicine, etc. It should draw upon only topics we have covered (rather a restrictive requirement initially), and it should grow out of your own experience, perhaps something you noticed, ran into in another class, heard about in the newspaper, etc. You should point out how physics applies, and how it clarifies something about this topic in some way, using only the simple kinds of arguments we are learning to make. It should include a numerical estimate and a computation. Do not just find something on the web and appropriate it wholesale. I won't OK such a thing, and your eventual presentation must use only the blackboard, not computer projection or web resources. Write up your idea in a clear exposition of maybe one page. I'll make suggestions when I see it, and we will refine it together. Aim to make it something you can present as a 5 minute topic for the class as a whole. A good presentation is worth an increment in grade.

(2) Make a comment or raise a question in class that takes us in a new and productive direction. When you think you have done this, write me an email message repeating the remark, and say why you think it was productive. If I agree, I'll file it in my extra credit folder. Two of these should be worth an increment in grade. Limit to one increment in grade for the semester, but don't let that inhibit you from making more contributions!
