All I wanted for Christmas was a Tesseract!
Chocolates, clothes and a book to read are great Christmas presents, but what I really wanted was a 3D Tesseract!
“In geometry, the tesseract is the4D analogue of the cube; the tesseract is to the cube as the cube is to the square. Just as the surface of the cube consists of six square faces, the hypersurface of the tesseract consists of eight cubical cells. The tesseract is one of the six convex regular 4-polytopes.
The tesseract is also called an eight-cell, C8, (regular) octachoron, octahedroid, cubic prism, and tetracube. It is the four-dimensional hypercube, or 4-cubeas a part of the dimensional family of hypercubesor measure polytopes. Coxeter labels it the polytope.
According to the Oxford English Dictionary, the word tesseractwas coined and first used in 1888 by Charles Howard Hinton in his book A New Era of Thought, from the Greekτέσσερεις ἀκτίνες(téssereis aktines, “four rays”), referring to the four lines from each vertex to other vertices.[5]In this publication, as well as some of Hinton’s later work, the word was occasionally spelled “tessaract”.” (source: Wikipedia)
