The Great God Mystery



“The Great Math Mystery” is a PBS NOVA documentary about the nature of mathematics. It´s obviously quite basic, but still a good introduction to the subject. Mario Livio, who has written several books on the topic, is prominently featured. Roger Penrose and Max Tegmark are other well known scientists interviewed. Most of the documentary explores the “essentialist”, “realist” or “Platonist” idea that mathematics is an objectively real phenomenon “out there”, independent of our puny human minds. Indeed, the narrator – taking his cues from Tegmark -  suggests at several points that the world simply *is* an intricate web of mathematical properties and relations. 

“The Great Math Mystery” does dare to mention Pythagoras, and even interviews a female jazz musician who defends his ideas. Two ideas studiously avoided, however, are God and Intelligent Design. This is almost comic since, of course, the realist position is a strong argument for God´s existence. Indeed, one of Livio´s books is titled “Is God a Mathematician?” 

The latter part of the program explores the opposite idea: that math is a construction of our minds. Some humorous experiments with human child prodigies and lemurs (yes, lemurs) are featured, but they prove neither position – even if math comes von oben (or von Demiurgos), our brains must obviously be adapted to receive the information. A better argument is that engineers frequently *don´t* use exact math to build new gadgets. I think the Egyptian and Muslim high cultures had the same approach to math – only applied math counts, actually building pyramids is more important than Euclid´s axioms. Perhaps math works so stunningly well because our scientists have chosen to concentrate at (and marvel at) those parts of the universe where it does work? But what about psychology, sociology, meteorology and large chunks of biology, where math doesn´t seem to work just as good? (Not even ants seem to care about Hamilton´s equations!) 

I admit a certain sympathy for both positions in this debate. On the one hand, mathematics does seem to have curious properties which make it difficult to believe that it´s just some kind of clever contraption made by a distant relative of the lemurs known as Homo sapiens. On the other hand, it´s equally difficult to believe that this half-lemurian has managed to solve all the questions of the cosmos by discovering pi, Fibonacci numbers or the googolplex. I get the feeling that the “Platonist” position, while intellectually appealing, is really connected to Western scientific hubris. 

Yes, God might indeed be a mathematician, but I suspect he-she-it is many other things besides…
