Some random facts are so fascinating, funny, or unexpected that they can stick with us. Whether it’s an obscure piece of history, a weird scientific discovery, or an odd cultural tidbit, there are many not well known facts stored away for the right moment. What’s your favorite random fact that most people don’t know, and where did you learn it?
I always learned 22/7 = 3.142
Also close enough for most situations that don’t need extreme accuracy
True that, and 22/7 is the first approximation I learned around 8th grade. But I had already learned π to 50 decimal places in 4th grade…

So by 10th grade I was studying computer programming, on my own, not a school class. Anyways, I found myself fascinated by mathematical algorithms, and ended up (amongst other things) writing a decimal to fraction converter.
When I chucked π through it, it gave me 355/113
