Tat, Your essay really enlightened me. You simplified physics for me, unlike others I have never taken physics and I admire that you have a way of discussing confusing subjects, such as physics in a way that someone who knows nothing about physics is still able to understand. Your essay took a different approach from others in the class, which is really neat. I really can't think of anything that you can add, because I really don't know too much about physics or biology, except a simple understanding of them both. Overall, excellent job!!!!
