Bathsheba creates 3D sculptures using metal as her medium. Here she creates the shape of the Borromean Ring.
This is one of a delightful class of objects known as Seifert surfaces. Every knot and link (in mathematics knots are closed loops, links are assemblages of knots) has a continuous surface which it is the edge of. An introduction to these surfaces, along with free software to generate them, are at the SeifertView site.
These surfaces are often beautiful, especially for symmetrical knots and links, and here I’ve produced one of the sweeter ones. This surface has three edges, each a simple closed loop, which are locked together in an ancient form called the Borromean Rings. Named after its use in an Italian coat of arms, these three rings are locked together inextricably although no two of them are linked. Their Seifert surface twists through the loops smoothly and gracefully, and I’m very happy with the organic mesh. It’s wide enough to let light through, while responding sensitively to the curvature and giving a tactile texture.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
