Tat, I think it is neat that you incorporated something that deals so closely with nature and has not been talked about much before in this class. I know little about the sciences and was able to draw a lot from your essay. I would suggest you go through the paper and check for a few grammar errors. Also I noticed in the beginning when you list the sciences you say there are three which you will talk about and then list only biology and physics. Make sure you list the 3rd. Good writting and so informative. Julie
