Jim Holt fears the web disrupts the connection between memory and creativity. He uses the French mathematician Henri Poincaré who died in 1912 as an example:
How to account for the full-blown epiphany that struck Poincaré in the instant that his foot touched the step of the bus? His own conjecture was that it had arisen from unconscious activity in his memory. The role of this unconscious work in mathematical invention appears to me incontestable,’ he wrote. These sudden inspirations … never happen except after some days of voluntary effort which has appeared absolutely fruitless.’ The seemingly fruitless effort fills the memory banks with mathematical ideas ideas that then become mobilised atoms’ in the unconscious, arranging and rearranging themselves in endless combinations, until finally the most beautiful’ of them makes it through a delicate sieve’ into full consciousness, where it will then be refined and proved.
