[math-fun] next breakthrough?

i know this is vague, but my wife was reading about the history of i and wondered what the next great fundamental conceptual breakthrough might be. it took something like 1500 years for complex numbers to get understood and now they're used everywhere. it's now been about 250 years and she was wondering what might be the next breakthrough be that could be as consequential as complex numbers are. /bernie\ -- Bernie Cosell bernie@fantasyfarm. com -- Too many people, too few sheep --
