As you are walking out of class one night, you discover a notebook, full of equations, belonging to a professor in your school. You write a note telling him who you are and where and when you found it. Then you put the note in an envelope and drop it into one of the university's internal mailboxes.

If found, please return to Professor Doddering in Room A123."
