Math Monday: 3D Hilbert curve in steel pipe
By George Hart for the Museum of Mathematics Back in March, this column showed a 3D Hilbert curve made of 64 PVC plumbing elbows arranged in a 4x4x4 cube. Chaim Goodman-Strauss has since outdone himself with an 8x8x8 cube of 512 steel elbows that he made with Eugene Sargent: It is springy, but strong enough […]
Handmade steel umbilic torus
calculus-book-cover.jpgMy buddy Trent Johnson, who works for AMD here in Austin, made this beautiful object. I was standing awkwardly in the corner at his birthday party last weekend, trying to remember how to interact with flesh-and-blood people on a face-to-face basis, when I looked down and saw it leaning against the wall next to me. And I immediately recognized it from the cover of my college calculus text, from the flyleaf of which I now quote:
Math Monday: Gyrangle
By George Hart for the Museum of Mathematics As announced a few weeks ago in this column, I made a large mathematical artwork at a public “sculpture barn-raising” on the National Mall in Washington DC last weekend. Hundreds of people helped me screw together these 490 laser-cut triangles into this structure which illustrates a discretization […]
Math Monday: Wire torus challenge
By George Hart for the Museum of Mathematics Here is a weaving challenge for serious makers: Can you take a single length of wire and weave it into a 3D donut surface as shown in this image? The two ends of the wire are joined with a small crimp, so it is all one continuous […]
Math Monday: What to Make from Drinking Straws?
Two methods of making geometric models from drinking straws.
R.I.P. Benoรฎt Mandelbrot, 1924-2010
Wired and others are reporting that Benoît Mandelbrot, the mathematician and father of fractal geometry, has passed away, just shy of his 86th birthday. On GeekDad, Matt Blum writes: I had the rare and amazing privilege of hearing Mandelbrot speak when he came to visit my high school about 20 years ago. Even at my […]
