24 Math and Science Facts People Can Never Forget

We all, at least barring homeschooling or a strange, feral wolf-boy situation, learn science and math growing up. But apparently, some people choose to actually store that knowledge, instead of immediately jettisoning it in favor of Simpsons quotes. Personally, I would respond to the label “a math or science fact you’ll never forget” with “give it your best shot.”

Nevertheless, somebody needs to send rockets to space, so there are people who devote their lives to these pursuits. In a Reddit thread, they locked and loaded their absolute stickiest science and math facts and fired them off, hoping they would lodge in a layman’s brain. The best are below — and I’ve already forgotten most of them. 

The idiots win again!

Porksoda32 4y ago I know lots of folks are familiar with the thought experiment of drilling a hole through the center of the earth and dropping a ball into the hole in a vacuum, which causes it to fall back and forth at a fixed (and fairly easily calculable) frequency (we're ignoring earth's rotation). What blows my mind is that the hole doesn't have to pass through the center of the earth. You can drill a hole between any two points on the globe, and a ball moving frictionlessly between those two points will oscillate with the same frequency as
Blamblam2020 4y ago If you're copying out numbers by hand / on a computer, and you have a difference between what you wrote and what you copied from, if the error is divisible by 9 then it is a transposition error (meaning you mixed up the order of the numbers i.e. put 996 rather that 969)
