There are times when the world seems to run along quietly from day to day, with very little happening. Then there are times like these. There are the ongoing aftershocks in Christchurch, many of them big enough in their own right to qualify as major quakes at any other time. There was the far larger earthquake in Japan, with its ensuing slow-motion nuclear disaster. There are wars and revolutions across the Middle East and North Africa which seem set to transform the politics of those regions. Millennial anxieties are on the rise once more.
