A beautiful representation of the theory of four-dimensional space….

(When we think of the “tesseract” we are reminded of our favorite books of childhood, A Wrinkle In Time.)

“A series of images from Charles Howard Hinton’s The Fourth Dimension (1904), a book all about the “tesseract” – a four-dimensional analog of the cube, the tesseract being to the cube as the cube is to the square. Hinton, a British mathematician and science fiction writer, actually coined the term “tesseract” which appears for the first time in his book A New Era of Thought (1888). We are not going to pretend to have given the time to his book to understand fully the concept behind these diagrams, but they are a fascinating series of images all the same (particular the coloured frontispiece featured above), and offer a glimpse into the theory of four-dimensional space which would prove so important to the development of modern physics. Although Hinton’s work was an important stepping stone in understanding four-dimensional space, the real breakthrough came in a 1908 paper by Hermann Minkowski, in which four-dimensional space was thought of in non-Euclidean terms, leading to the revolutionary concept of “spacetime”…”
