Are you craving your daily dose of math and science? Veritasium is here to fill our brains with all kinds of interesting facts about geometry and patterns, eventually leading to a demonstration of interlocking tiles that can extend infinitely across a plane without ever repeating their layout.
THE BEST Geometry
Magnetic Games presents yet another wonderfully satisfying video, in which he uses hundreds of magnetic rods and spheres to create an complicated geometric sculpture. He placed a light at the center of his masterpiece, so it casts interesting shadows as well. After it’s all done, he knocks it down with a catapult.
The guys at ThunderDomes are in the business of building geodesic domes. But they also make some nifty LED lamps, which use 3D printing and cast resin structures to throw dramatic shadows onto walls, ceilings, and floors. They come in a variety of designs, with our favorite being the golden ratio spiral pattern.
Makers of cool metal objects AltDynamic are back with another really sweet design. The Tesseract is a CNC-machined aluminum cube within a cube that looks like a rare totem from another dimension. It comes in three sizes: 1.9″ Mini, 2.4″ Mighty, and 2.9″ Mega, in raw aluminum and three anodized colors.
Despite their YouTube channel’s name, The Philadelphia Robot Factory has significantly more magnets than robots. In this highly satisfying video, they disassemble a hefty hexagonal structure they made from 50,000 individual magnetic spheres, layer by layer. Now enjoy the same in reverse.
You’d think that when you say you want half a sandwich, it would simply take a straight cut down the middle to get your 50/50 share. But Numberphile explains how it’s not quite that simple of a task if you really want exactly half. Now how to apply theory to reality…
