As part of the application to a particular university, I can submit a research supplement which is a paper I have written which will be reviewed by the university's faculty. However, it must be accompanied by a letter from a 'research supervisor' regarding the work.
The paper I have written is based on a paper written by a professor from another university, and as I am currently in high school and none of the staff here can review it, I thought it would be great if I could get said professor to write such a letter.
Firstly, would it be appropriate to send such a request, and is it likely to be fulfilled?
Note: For the purposes of your answers, you may assume the paper is in fact correct, and a serious piece of research, which although it presents original results, is 'orthodox.' I am aware professors sometimes get sent crazy letters from people with wacky theories (I've even seen some crop up on the physics SE).
