actually, without linear time, you could have already graduated
and Schrodinger's Cat is amazing, although most people don't really get it...
here's a thought, what if time were infinite?
or, the question we came up with in class: If you lived for an eternity, and had the means to write forever (in a book with an infinite number of pages), and you wrote one a year, on your birthday, about one day (on your first birthday, you write about you first day, on your second, your second, etc.), Will you ever eventually write about your whole life (every day you are alive)?
