Math goddess Vi Hart & mathematician Henry Segerman’s virtual reality animation reveals the gorgeous crystalline formations inherent in hyperbolic 3-space, the negative curvature equivalent of 3D Euclidean space. Great to see it this week on the New York Times “Daily 360” VR platform. This beautiful visualization gives us a psychedelic update on the ground-breaking animation in the legendary 1970’s math film “Not Knot” which describes relationships between knots and hyperbolic space. This mind-blowing film is available here on You Tube. And here’s the original version of Hart & Segerman’s film from 2016 – simpler graphics but more detailed geometry.
