<p>I saw on the Caltech application that you can include any research papers that you have written. Well, I had done some research this past summer at a university and had created a pretty detailed powerpoint and presented it at the end to some staff. It basically contained everything that a paper would include, such as an overview, purpose, procedure, results, graphs, applications, implications, etc. Would the admissions committee accept a powerpoint (converted to pdf of course) as a substitute for an actual paper as a supplemental material?</p>
<p>Call admissions and ask. They don't bite. Though if you want me to guess, I'd say go ahead and submit it. If they aren't interested they'll simply ignore it.</p>
<p>What you have isn't a traditional research paper per se, but go ahead and submit it. Like ^ said, it can only help - not hurt.</p>
<p>... and actually the PowerPoint format is pretty friendly for a quick read to see what you did, as opposed to a full formal research paper which would take a lot more effort to go through. I would say definitely send it.</p>
