Like most mathematicians, I think, I’m irritated by the way “grows exponentially” has come into common parlance as a synonym for “grows rapidly”; whereas exponential growth in mathematics may be fast or slow, depending on the current level of the quantity. This has even crossed into technical discussions, as when I heard a talk by a cancer expert who objected to standard claims that cancer mortality increases exponentially through adulthood — which it does — because the levels actually stay low through the 50s, and so only “increase exponentially” after that point.
Anyway, I was under the impression that the vernacular application of this mathematical concept was fairly recent. So I was intrigued to find the cognate concept of “growing geometric” popping up in Evan Thomas’s Nixon biography, on the Watergate tapes. In the context of cancer. Used correctly! It’s quite a famous part of Watergate lore, where John Dean refers to Watergate as a “cancer… close to the presidency”.
We have a cancer — within — close to the presidency, that’s growing. It’s growing daily. It’s compounding, it grows geometrically now, because it’s compounding.
After the November US election I agreed with many commentators, who said that Comey really should resign for his failures of judgement or (depending on who you’re listening to) malfeasance with regard to the Clinton email server investigation, that it would provide partisan satisfaction for Democrats for him to be forced out, but that it was essential for the nation for him to stay in office as an independent check on the president’s authoritarian impulses. Some said he has the most secure job in Washington, since Republicans and Democrats both wanted to keep him, albeit for very different reasons.
We’re used to thinking of scandals as something that will damage the politicians involved if and when they come out, possibly driving them from office. But that’s not always how it works. That isn’t even really the fundamental dynamic. Hidden criminality by people in power locks them in a death struggle with the rule of law and the system of honest democratic politics. Only one can survive. If the politician has weak support, or self-doubt, or respect for democratic norms then it’s like a moon in Jupiter’s gravitation — for all intents and purpose we can just say it’s the massive planet (the constitutional system) acting on the small body. But it can be more like a black hole interacting with a star: Both are perturbed, and until they get close you can’t judge how massive the black hole is. (more…)
