University of Minnesota researchers Douglas Arnold and Jonathan Rogness created an engaging and (relatively) simple video explaining the abstract and mind-bending mathematics of Möbius transformations. From Science News:
A Möbius transformation begins with a plane and moves each point to a new location according to certain rules. In their video, Douglas N. Arnold and Jonathan Rogness of the University of Minnesota in Minneapolis transform a multicolored square into new shapes using Möbius transformations...
"You need some pretty heavy mathematical machinery that people usually don't do until their first year of grad school to prove the stuff in the video," Rogness says, "but we've been showing this to high school students and they seem to get it."
I use this rocker garlic crusher several times a week. To use it, you just put a peeled clove of garlic under the crusher and rock the crusher over it a few times. It will smash the garlic through the holes, which you can then add to your food or skillet. When you are done, […]
Archilogic made this interactive 3D model of the Scranton branch of Dunder Mifflin from The Office. You can scan over the entire space under “floor plan view,” starting off with Pam’s desk and the office of Michael Scott. Then head past the galley kitchen and men’s and women’s bathrooms. You can zoom in and get […]
When you can’t wait for the world’s longest meeting to end, the mindless leg bouncing makes your boredom obvious and just annoys everybody else. Everyone knows the TPS reports need the damn cover sheet, but some sadistic colleague keeps forgetting, probably on purpose just to eat into your lunch hour. Enough is enough!While serving a […]
What could be more fun than a slingshot that shoots tiny airplanes? A slingshot that shoots tiny glowing airplanes of course! These toy planes are outfitted with ultra-bright LEDs, so you can fly all night without losing them in the trees.Whether you are a regular-sized child, or an overgrown adult one, these light-up flyers offer […]
You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
