December 2007 / Blaise Pascal / 1623 – 62

It is with Blaise Pascal that the drumbeat of the infinite becomes to loud to ignore. He eerily echoes Cusanus when he talks of: “The two infinites which are to be found in all things, infinite largeness and infinite smallness.” The absolute maximums and absolute minimums of Cusanus, or, as I prefer, the opposites that aren’t. We can contemplate but not fully conceive the potential infinities in the old Aristotelian sense, but the double infinity is the hallmark of nature. Descartes carries the same idea even further forward but prefers the word ‘indefinite’ thus getting ever closer to string theory.
There were some other major contributions to mathematical theory by Pascal. Some were particularly germane to our discussion, and others a little less so. Early on he contributed to the study of fluids and vacuums resulting in the barometer. Some other primary examples are the foundations of probability theory with Fermat, his work on conic sections which so influenced Leibniz, and of course the Pascaline. The latter, for good or ill, was one of the world’s first digital calculators in 1642. He also was responsible for one of the clearest statement of scientific method in the 17th Century.
Blaise Pascal was a child prodigy and, like many other prodigies, he burned out young. After the age of 18, ill health dogged his relatively short life. There was however an aspect to this youth that still resonates for us going forward into the future. His father. Etienne Pascal, was a member of a group of perhaps the most eminent thinkers and scientists of Europe at the time (including the likes of Descartes and Desargues). Every Thursday or so they met at Marin Mersenne’s home to discuss the latest in mathematics, science, philosophy, and theology. From the age of 14 on his son quietly attended those sessions. Mersenne himself contributed the Mersenne Prime that is intimately connected to the so called perfect numbers from Euclid to Euler. Even today it is vital to encoding, and the Pascaline, in its latest distributed computing form, bears on that also.
Mersenne though, as ‘the Father of Acoustics’ may have influence way beyond what is currently attributed to him. His oscillating frequencies and their relationships to various harmonies begin to have a tone in string theory. I don’t pretend to understand the math, I just hear the music. But it is the dance – the math and the music – that ultimately will be key (should I say chi?) to comprehending the vibrations. There, and probably only there, will the X Factor shimmer into relative focus.
