Mystery of the Day
I have a new Mystery of the Day!
I was looking up how to solve a partial differential equation in my diffeqs book , and so I was looking for the index. My book fell open to a page with an unusual bookmark in it. The bookmark appears to be a sheet from a German day planner with a picture of an anime girl on it. I wonder where it came from.
