three-gear meshes that actually work

A nice little bit of fun on Friday. You’ll see, pretty often, illustrations of gears for some sciencey or engineering-invoking illustration or logo, and they’ll be all shiny and pretty and stuff, right?

Problem is, those gears can’t turn. They’re wedged together. Play with it in your head, you’ll see one gear is forced to turn in two directions at the same time, and of course can’t.

So Numberphile – who has a youtube channel – decided to come up with some three-gear systems that actually work. They’re really cool. Enjoy:

anti-queer initiative signatures lying about their initiative

PAID I-1515 SIGNATURE GATHERERS ARE IN SEATTLE TELLING PEOPLE THAT IT'S A PRO-TRANS-RIGHTS INITIATIVE, RELYING ON COMPLETE IGNORANCE - DON'T FALL FOR IT, DON'T BE STUPID, REPORT IT IF YOU SEE IT.

In real life, I-1515 is a vicious anti-queer initiative that actually targets trans kids with abuse and puts a $2500 bounty on their heads and I am not even making that up.

IF YOU SEE IT, SAY SOMETHING.
