When buying $10 dust specks, do not get carried away and buy 3^^^3 of them. You won't save any money that way.
What is 3^^^3? I see it a lot here, why is it special?
It's a ludicrously large number in Knuth's up-arrow notation used in some posts as an example of a number which is finite, but large enough to ludicrously surpass reasonable finite numbers like the size of the universe, or the number of possible states of a volume the size of the Solar System, or whatever.
