Hinton’s Cubes

In 1906 an English mathematician named Charles Howard Hinton published a book arguing that the fourth dimension was not merely something to be calculated but something a person could learn to see, given enough practice. His method was a set of small painted wooden cubes, each with its own colour and name, to be handled and memorised until four-dimensional shapes felt as familiar as a chair. Because it required a box of several hundred hand-painted blocks, almost nobody ever tried it. This is that apparatus, working, in a web page. Start at the first tab and go in order: learn the colour names (each direction adds a colour, so red plus yellow makes orange, and the names build themselves), then handle the cube and turn it, then meet the tesseract — drawn as three separate blocks side by side, because a four-dimensional object cannot honestly be shown any other way. Then drill. The drill is the actual method; everything before it is setup. No mathematics is needed. It is less like…
