We’ve covered the in-space science experiments of astronaut Dr. Don Pettit before. Here’s a compilation of a number of microgravity experiments he’s conducted while onboard the International Space Station. Saturday Morning Science More: Zero-gravity coffee cup
You can’t get very far in exploring the expanding realm of citizen science without bumping into the names Tito Jankowski and Eri Gentry. Tito has been involved in DIYbio, the global amateur biology org with local chapters, the Pearl Biotech Gel Box project (the open hardware gel electrophoresis system), and OpenPCR, the open-source PCR machine. […]
Citizen Scientists: Show us your Erlenmeyer flasks, your test tubes, your centrifuges, your stereomicroscopes, your mutant science experiments, yearning to be free. It’s Citizen Science month here on MAKE, an opportunity for us to feature a lot of the science content from the magazine and here online, a chance for us to collaborate with people […]
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 […]
