The Beauty of “up” and “down”: Is This Merely Coincidence?
up and down can be abbreviated as “up” and “dn”. Did you see the beauty? Yes, they are double flip of each other as the picture below.
I got this idea when I was coding a program in which I named a variable Xup and Xdn and I accidentally noticed the beauty. I don’t quite positive about the coincidence for this phenomenon. Is it possible that when we dig more about the root or the origin of these words, we will see the graphical relationship of the two? Are they the symbol of gender? Anything to do with the “holy grail”?(I’m totally kidding for the last one hee hee hee ^_^)
