In this video I'll share with you some of the things that interested me about shapes of constant width. Information about some of the stuff shown here was pretty tough to find online, like the visual representation of the Minkowski sum and the construction of the Meissner tetrahedron. For more information, 3d models and the templates I used: https://www.rad-head.com/ I also made a build video where I show the process of making this set of shapes: https://www.youtube.com/watch?v=BVs9NPYgmRk If you like what I do and want to support rad-head: https://www.patreon.com/radhead A great book on the subject (affiliate link): https://amzn.to/2pT72JK Similar products from some pretty cool guys: https://mathsgear.co.uk/collections/shapes/products/shapes-of-constant-width-in-acrylic-set-of-4?variant=876663997 https://mathsgear.co.uk/collections/shapes/products/solids-of-constant-width Music: www.bensound.com
