Adventures in Mathematical Knitting
Rendering mathematical surfaces and objects in tactile form requires both time and creativity
sarah-marie belcastro
Three-dimensional mathematical objects can be challenging to visualize, even with the help of computer graphics. Mathematician sarah-marie belcastro uses knitting to create mathematical surfaces that can be manipulated and, in some cases, worn. The process of figuring out how to successfully knit a given surface, belcastro says, requires a deep understanding of the structure. The author has been knitting mathematical objects for 20 years; in this photo essay, she discusses her process and offers examples of knitted objects including Möbius bands and Klein bottles.
