The arbitrary grouping of tens places our number system at odds with what’s real and true in the world. Suppose evolution had left us with four fingers instead of five, would we have adopted an octimal instead of decimal system? Would we count “onetwothreefourfivesixseveneight” while writing “123456710?” And would that convention be better, worse, or just different?
A couple of years ago I overheard a friend toss off the phrase “the difference between a first and second derivative” with a familiarity that made me jealous. I started reading books with titles like “Infinite Ascent” and “A Tour of the Calculus,” books about numbers. Not numbers of things, but numbers themselves: squares and square roots, series and patterns, the philosophy of zero and the inevitability of pi. There are many truths buried in numbers, but the way we write them down obscures them. Prime numbers are real; counting on our fingers is not. Square roots are true in and of themselves, counting down from ten to liftoff is pure artifact. I turned 49 yesterday. 49 shouldn’t matter. 49 is the last exhibition game before the start of the season, the dark theater before the movie, the vicepresidency of ages. Fifty – now there’s a momentous year. Fifty, as in half a century or a diamond anniversary or “sorry – I can’t break a bill that large.” But the brave 50 is a fraud: five groups of ten, two groups of twentyfive, like one of those toys that changes from a truck or a plane into a robot. 49, on the other hand, is number royalty: a square of a prime number, part of the noble series 1492549. The squared prime number series makes a lot of sense. Years go by too quickly now. The narrative breaks down: each year things are different but they’re not different enough. Are you better off now then you were a year ago? How can you tell what’s background noise and what will ultimately pass the “So what” test? Decades are pretty speedy too, and worse, they are inconsistent. Decade identity fizzles out over time: Teens and twenties are periods of tumult and revolution, of emerging identity, of atmospheric highs and fall and cut your forehead on broken glass in the parking lot lows. But the thirties don’t roar and the forties just…. happen. Take the prime squared intervals, however, and it all makes sense. Sure 9 to 25 is huge but 25 to 49 is epic: we create families, make and lose fortunes, we matter. We fall, redeem, shine, disappoint, lose ourselves for months at a time in minutiae and emerge with perspective and the vaguest sense that wisdom and peace may ultimately be attainable. Way too much for ten years to handle. 1492549. 49 is the last of the line, but that’s not a bad thing. None of us will make it to 121. 49 is the black belt of years: everything really starts from here. (from March 2008)
