If I may, the whole essay in itself failed to catch my interest as a reader. From the first hackneyed line, it was pretty obvious which direction the essay was heading.
To put it simply, I am hopelessly infatuated with learning more, seeing more, and understanding more about the world around an inside me.
^Lines such as those rarely do any good, due to it's exaggerated, unrealistic and cliched nature.
Learning just the basics of chemistry radically changed my view of the world. I loved that I could look at steam coming off my soup or hear the fizz of a pop can and know exactly what was happening
^Radically changed your view of the world? That is a bit extreme, especially considering the example you have used.
I felt like nothing could possibly link them all, but studying the brain gives me the opportunity to conduct research on anything from artificial intelligence to the biological origins of creativity
^Well, that does depend on the resources, for research, that are made available to you.
As far as I'm concerned, the doors are wide open.
^They definitely are. It is strange that you chose to discuss in some level, your interest in Chemistry and Cognitive Science, and then end it as if you are unsure as to what it is you want to study.
Your essay in general is quite weak and quite frankly, boring. There is nothing interesting in it, and there is nothing in this essay that conveys a positive characteristic about you.
