Tesseract rotating in the fourth dimension (Hise, 2006). |
The principle of 'The Unreasonable Effectiveness of Mathematics in the Natural Sciences' would seem to point to the reality of the Fourth Dimension. So why don't we perceive this Fourth Dimension?
Let's talk for a moment about Newton's laws of motion. He managed to concoct a single mathematical description that explained two entirely different orders of phenomena: a planet orbiting its star and an apple falling from a tree.
In 1960, physicist Eugene Wigner wrote an article titled The Unreasonable Effectiveness of Mathematics in the Natural Sciences in which he remarked on the almost magical manner in which mathematics serves as the ideal language for formulating the laws of physics.
Beyond Newton's laws, another common example are Maxwell's equations, which provide the basis for classical electrodynamics, classical optics, and electric circuits. These serve as the foundation for all electrical, optical and radio technologies.
"The enormous usefulness of mathematics in the natural sciences is something bordering on the mysterious and that there is no rational explanation for it," Wigner wrote.
It seems that it was this same sort of awareness of the mystical nature of mathematics that inspired Plato to create his World of Forms.
In his paper, Wigner noted that a physical theory's mathematical structure frequently provides clues to further advances and can even lead to empirical predictions. Plato would love to hear that. Plato was the master of making predictions from theory though he never cared much for empirical confirmation.
The magic of mathematics is that it can be used to create laws which seem to exist in a reality somehow higher than that of the physical objective world.
Platonist Henry More was the first to use the term "Fourth Dimension" though he used it to refer to Plato's World of Forms and not a fourth spatial dimension. Still as we have seen, Plato is responsible for both the idea of alternate dimensions and that of a spatial dimension beyond the usual three.
It was 1637 when Descartes published his work on what would come to be known as the Cartesian Coordinate System. This system merged geometry with algebra and led to the development of calculus.
On one hand, people were fascinated by the correspondence between the three dimensions of physical objective reality and the way they were so perfectly captured by the cubic cells of the Cartesian Coordinate System. On the other hand, mathematicians were making calculations in four dimensions. These calculations are conducted in four-dimensional Euclidean Space. These facts, taken together, seemed to indicate that there must be a spatial fourth dimension somewhere beyond our ability to perceive.
In 1827, as I noted in The Gnostic Notebook: On Plato, The Fourth Dimension and the Lost Philosophy, August Ferdinand Moebius wrote:
"… two equal and similar solid figures, which are however mirror images of each other, could be made to coincide if one were 'able to let one system make a half revolution in a space of four dimensions. But since such a space cannot be conceived, this coincidence is impossible in this case."
Moebus had already taken the first few steps into the Fourth Dimension. In 1880, W.I. Stringham’s published an article titled, "Regular Figures in N-dimensional Space", in the American Journal of Mathematics. In this article he included sketches of various higher dimensional shapes, including the tesseract.
