- Should one mention multiple, albeit somewhat unrelated research interests?
- Should I talk about a unpublished paper in my SOP?
Besides physics as my major, my other interest is linguistics, and as you can see, there is no overlap. When I was in high school, I wrote my first article in linguistics. It hasn't been read by any professor or published in any specialize journal, not because it was rejected, but because I haven't tried to do so. I had a graduate student in linguistics review it for me, and it seems that she finds it interesting. As far as I know, there is currently no material on the topic I researched available on the internet, which indicates that the topic is new.
Because (1) it is the first article I have ever wrote, (2) I did it when I was 16 or 17 (although I have updated so much it lately) and (3) the topic is new so far, I consider it my proudest scientific activity. I think putting it in the SOP will make a steady point that "I was born for scientific research." Will it be useful if I do that, or just mention the latest article in physics I wrote?
