I hope the year has started well for you. Let's make 2021 a great year!

Panel 1:
G and H are walking into a room labelled: "Prof. Owl's Fabulous Escape Room"
G: Wow, an escape room designed by Prof. Owl. I’m really excited to see how this will go!
Panel 2:
G and H are walking back out of the room, looking angry.
G: Man, that was impossible. Did we actually solve any of the puzzles?
H: No, don’t think so. What a waste of time.
Panel 3:
Prof. Owl, watching in disbelief.
O: Whaaat? They didn’t solve it? How did they not immediately see that the number of grains of sand in the lamps corresponded to the amount of times the submanifolds of the four dimensional space the lamp shades were shadows of could be folded to form their fundamental group? I mean, that paper was published almost a year ago!
