Tipping point: when a seemingly insignificant shift in one variable causes a structural, irrevocable transformation in the system. Whether it’s the onset of a hurricane, a stock exchange crash, a star implosion, an influenza epidemic, or a nasty temper tantrum, the dynamics of the tipping point remain the same: shit hits the fan before you knew there was a fan.

In politics the tipping point has an especially dramatic implication: a seemingly insignificant change in one legislation can lead to a drastic change in the system of governance.
