Math Monday: Geometric origami

Math Monday: Geometric origami

By George Hart for the Museum of Mathematics Each year I visit the annual Origami convention in New York City, and this year, as always, I was impressed by the wide range of works on display. The mathematical examples get more sophisticated each year. Here are just four examples to illustrate a range of folding […]

New in the Maker Shed: Cooking for Geeks

I’m very happy to announce the availability of Jeff Potter’s Cooking for Geeks in the Maker Shed. I met Jeff while he was making ice cream with liquid nitrogen at a party sometime last year. I don’t think I’ve been more excited about a cookbook in my life. If you were ever curious about what you eat beyond the ingredients and recipe, then Cooking for Geeks is for you.

How-To: Extract DNA

How-To: Extract DNA

The page below, from the Universe of Utah’s Genetics Science Learning Center, shows you how easy it is to extract DNA strands from any living thing (but stay away from living things that might be pissed at you for liquefying a half a cup of them in a blender). The rest of the Learn.Genetics site […]

Dabbling in alchemy

Dabbling in alchemy

Math Monday: Found objects

Math Monday: Found objects

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 […]
