By George Hart for the Museum of Mathematics Here’s a challenge: Make something cool from binder clips. It will be tough to beat this spherical construction by Yang Enqi. Using one handle, five clips of one color are linked cyclically into a pentagon. Using the other handle, twelve of these pentagons assemble like a dodecahedron […]
Have you ever been curious how a glow stick works or how they achieve all those wonderful colors? In this video from NurdRage you’ll learn what it takes to generate the chemical energy needed and how to harness it to create various colors in the spectrum.
When I was a teen, I was fascinated by alchemy — not so much the whole turning lead into gold part or trying to play God and create tiny little humans in a jar. I was really attracted to the labware, the furnaces, the study of the physical and natural world and its processes — […]
By George Hart for the Museum of Mathematics Making geometric structures from commonly-found objects can result in some interesting effects. Here, sixty bicycle reflectors are joined into a spherical geometric construction by Nick Sayers. To connect them, he drilled four holes in each and fastened them together with small cable ties. Another example is this […]
When 17 year old Hayden Parker says he’s a backyard scientist, he means it literally. He’s converted the family backyard BBQ area into an outdoor chemistry lab where he shoots videos of his experiments. It’s a little harrowing watching him do some of these procedures, such as synthesizing nitric acid, and making some critical mistakes […]
Science bad boy Theo Gray shows you how to create lightning bolts in a piece of acrylic. OK, so you need the juice of a five-million-volt particle accelerator to get the effect seen here (via the Kent State Neo Beam’s Dynamitron): With the Dynamitron – rented for the day – adjusted to around three million […]
By George Hart for the Museum of Mathematics Kirigami is a traditional art of cutting paper. Ulrich Mikloweit takes it a step further by assembling many pieces of kirigami into intricate mathematical models. This is a snub dodecadodecahedron made from 924 cut and colored facets. Ulrich has dedicated years to making hundreds of such hand-cut […]
