Hideki Tsuiki is back in Swansea

We Hideki Tsuiki in Swanseaare glad to welcome Hideki Tsuiki in Swansea again.  This Thursday we really enjoyed his talk on “Imaginary Cubes —  Mathematics, Puzzle, Art and Education”.

Abstract: Imaginary cubes are three-dimensional objects with square projections in three orthogonal ways just as a cube has.   How many different kinds of imaginary cubes can you imagine?  In this talk we  show that there are 16 kinds of minimal convex imaginary cubes which includes regular tetrahedron, cuboctahedron, and two objects that we call H and T.  As we will explain, H and T have a lot of beautiful mathematical properties related to tiling, fractal, and higher-dimensional geometry, and based on these properties, the speaker has designed a puzzle, constructed three-dimensional math-art objects, and used them for educations at various levels from elemental school to graduate schools. In this talk, I will explain mathematics of imaginary cubes and show the activities I have been engaged in.  I will carry a couple of copies of the puzzle and some of the math-art objects so that the audience can enjoy them while I am staying in Swansea.
