By George Hart for the Museum of Mathematics Continuing our fiber arts theme of past weeks, today’s Math Monday offers an excellent example of mathematical needlepoint. This piece illustrates a Hilbert curve, taken to the sixth approximation. The continuously changing color of the thread makes it easy for your eye not to lose its place […]
Hans, a maker from Trondheim, Norway, sent us a link to this Wimshurst Influence Machine he bought. He asked about the history of the device from the seller and found out that it was used in a grade school, from 1911 to 1951, and was owned by the principal. Nice job on the restoration: The […]
By George Hart for the Museum of Mathematics After last week’s column on mathematical quilts, I thought I should continue in the fiber arts category with mathematical objects that can be made by crochet. Matthew Wright at the University of Chicago has crocheted some beautiful Seifert surfaces, shown below. These are (approximately) the form that […]
By George Hart for the Museum of Mathematics The traditional craft of quilting can be used to make many mathematical forms. While quilters have always used geometry to work out repeating patterns, some modern quilters go further in using mathematical objects as the subjects of their quilts. Here are two impressive examples by Sarah Mylchreest […]
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 […]
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.
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 […]
