Gift for my father. Dude likes astronomy and physics.

Very nice!

Since I teach physics the class spends quite a bit of time on Einstein.

And, I know that it is not "de rigueur" "of a dignified physics professor but I also take in a shop worn poster of I.Q. and tape it to the whiteboard before class! lol

again, very nice!

Thanks! My father is also a physics teacher. I really admire your profession.
