Figuring out something quickly by just using estimates to the closest power of ten, because sometimes you just want to know if [the thing you're doing] is worth or is gonna cost ten bucks, a hundred, or a cool grand. Named after Fermi Estimation, a trick used by Enrico Fermi to wow his fellow nerds at parties by estimating shit without knowing 100% everything about the problem, sometimes without even writing shit down. [You're not] going to get exact numbers, but you're gonna get close enough. Most notably, dude estimated the power of a fucking [nuclear bomb] by just dropping papers as the bomb went off and measuring how far the shockwave moved that shit — and he was only off by a bit.
