I'm note sure if this is mathematical, however I know that there's an area of maths about folding. And regardless, this seems like an interesting question that I have no idea how to solve.
I am designing a 5 day paper timetable for university that I will keep in my pocket so I know where and when my classes are. My current timetable is a table with days as columns, hours as rows and cells being classes. However when I came to fold this I found that it was awkward. In order to fold it small enough to fit in my pocket I needed to fold it many times, which in turn meant that to view some parts of the time table I needed to unfold it many times.
How can I fold a timetable so that to view any part requires the least amount of unfolding?
