General outline: "Dear blahblah,
Thanks a lot for response. Even though I realize that the projects represent a time investment that may seem unreasonable to a single high school student, I would still be very interested in having a look at the list, if this would be at all possible. Over the past years, I have familiarized myself with roughly the equivalent of an undergraduate degree in mathematics and physics, and I was hoping that I could draw some inspiration for my latest self-study project from your list.
