A Primer of Higher Space

About this book

Imagine a creature confined to a sheet of paper trying to understand a cube. Claude Bragdon begins with puzzles of this kind, then asks what our own three-dimensional world might look like from a fourth direction.

Lines become planes, cubes give way to the tesseract, and familiar shapes acquire unfamiliar possibilities. Written for curious readers with no specialist mathematical training, this short illustrated primer turns geometry into an exercise in perception. Its most interesting question remains open after the diagrams end: what could exist around us that our senses are unequipped to recognise?
