Tat, thank you for sharing you knowledge of some of the sciences with us. I can tell that you really enjoy it. You may want to talk about how science has impacted you as a person, not only impacted nature. And again, I encourage you to read aloud or have someone that has a better background in English and English grammar to go through your paper. You have some improper word and tense usuage that needs to be taken care of. Other than that, it's pretty good.
