Tunnelscope Circular Reflection Kaleidoscope: in this novel design a straight length of transparent acrylic rod provides the reflective surface, and two wheels filled with resin and interesting shapes of colored glass can each be turned separately to produce a flow of psychedelic patterns.

Solids of constant width to visualize cool properties of mathematics and geometry. This is a collection of 8 different solids of constant width. Included models are Meissner tetrahedron, revolved Reuleaux triangle, revolved pentagon, revolved heptagon, and four more. All models are made to be the same scale Higher infill or wall Summary This are 5 solids of constant width, split in half for better printing results. I got great results

The ultimate expression of the Reuleaux shape creates the most sophisticated shape with a constant width. Few surfaces keep their width while rotating on any axis; we're used to seeing this characteristic in spheres. But as incredible as it may sound, other shapes with the same property aren't circular, such as The Solid of Constant Width. Leonhard Euler discovered that the Reuleaux triangle always maintains the same width. Four spheres with equal radii, placed at the corners of a regular tetrahedron, form a three-dimensional version of the Reuleaux triangle but without the constant width. Then, Dan Bergerud replaced the tetrahedron's edges with a group of spheres touching the edges, creating a solid object with similar symmetry and constant width, the Ultimate Solid of Constant Width. In the mathematician world, it is known as Spheroform. It is the only three-dimensional shape that combines constant width and Tetrahedral Symmetry. It conveys the knowledge of one century of discovers and mathematical analysis to find the right equation that creates this shape,. What is so special about the Ultimate Solid of Constant Width?

An amazing demonstration of the Central Limit Theorem for the home or classroom!

The easiest 3D shape to think of with constant width would be the sphere but here are a few more. In the mathematician world, it is known as Spheroform It is the only three-dimensional shape that combines constant width and Tetrahedral Symmetry. Spheres are not the only solids that have the same width at any incident angle. An amazing demonstration of the Central Limit Theorem for the home or classroom! Few surfaces keep their width while rotating on any axis; we're used to seeing this characteristic in spheres. This beautiful design by Luycho uses both mirror anamorphic reflection and an accordion type lenticular dual image turning the plate degrees trades images. Specular Hologram Knot: this complex 3D image is created by etched grooves that reflect a point source of light as glints, and each eye sees a slightly different pattern such that, via stereopsis, the shiny points appear to float above or below the surface.

This assembly can make a number of surprising symmetrical forms including this rectangular prism with a square hole. A sphere is the orbiform of maximal volume, and the others are based on revolutions of the Reuleaux triangle, pentagon, and heptagon respectively. See if your eyes can follow the path of the gold bead representing a single random path in the fps slow motion segment of the video. This is a collection of 8 different solids of constant width.

There are other shapes that are capable of rolling as freely as spheres do. Zac Eichelberger, a mechanical engineer and design enthusiast demonstrated FOUR of them at work in tandem. The Reuleaux Polygons set comes with four incredibly intriguing solids of the same width, machined out of solid copper.

This assembly can make a number of surprising symmetrical forms including this rectangular prism with a square hole. This is an update to the previous Solid of Constant Width that I posted. See other aperoidic tilings in my collection. Althogh the math says they can tile the plane, getting them to do so is more challenging than one might think! I got great results Solids of constant width cults3d This is a collection of 8 different solids of constant width. Both Reuleaux tetrahedrons and revolved Reuleaux triangles present the same This set is the creation of the folks at thecuriositybox and will be shipped out in the next subscription box in a few weeks. You should be able to print all three and be able to use them interchangeably now! Spheres are not the only solids that have the same width at any incident angle.
