Do You Have the Time?
Someone came across this sign in Berlin, Germany, and couldn’t decipher the meaning of it. As it turns out, this is Berlin’s famous Set Theory Clock. This unique clock uses set theory to decipher and show the time. It tells the time using increments of fives and ones and in yellow lights.

Yep, that’s a clock. We’re so used to digital clocks these days, most kids probably don’t even know how to read analog clocks. And then this Set Theory Clock comes along and expects us to read the time in set theory. One person (probably a math wiz) managed to decipher this clock and said it reads the time 11:41.
