Poets, playwrights and novelists have all played around with exciting forms and patterns and frameworks that have mathematical shapes to them. But the shapes and forms that now populate the skyline are as informed by the aesthetic of mathematics as by its power to ensure the building doesn’t fall down.įor me, one of the most exciting revelations has been that even the art of the written word has mathematics hidden inside it. Architecture has a very necessary connection with mathematics, which is what guarantees the building will make it from the drawing board to the city landscape. The visual arts have an obvious connection to mathematics given that every time you paint a line on a canvas or carve a surface from a sculpture, geometry is emerging. While the abstract quality of music might make it a natural partner with mathematics, the other arts also provide fascinating examples of mathematical ideas bubbling away underneath the artist’s output. This prime number life cycle is believed to be connected with its ability to keep the species out of synch with a predator that also appears periodically in the forest. At the end of the six weeks they all die and we have to wait another 17 years before the next generation emerges. There is a species of cicada that lives in the forests in North America that has a very curious life cycle: the cicadas hide underground doing nothing for 17 years and then, in the 17th year, the insects emerge into the forest for a six-week party. The intriguing thing for me is that the musician and the mathematician’s attraction to primes to keep things out of synch can already be found in the natural world. The effect of the choices of prime numbers 17 and 29 are that the rhythmic and chords sequences won’t repeat themselves until 17 times 29 notes through the piece, by which time the movement has finished. So as the 17-note rhythm starts for the second time, the chords are just coming up to about two-thirds of the way through its sequence. If you look at the piano part, you'll find a 17-note rhythmic sequence repeated over and over – but the chord sequence that is played on top of this rhythm consists of 29 chords. In the opening movement, Messiaen uses the indivisible numbers 17 and 29 to create a sense of never-ending time. In this piece, Messiaen creates an extraordinary sense of tension by employing one of the most important sequences of numbers on the mathematical books: the primes. Take the 20th-Century composer Messiaen’s Quartet for the End of Time.
