Thinking rationally about terror

Here's a brilliant short New Yorker article on the subject of urban terrorism by the exceptional US physicist Lawrence Krauss.

His conclusion is sobering but appeasing:

... a mass killing like that which occurred in Paris would not significantly affect the death toll from guns in the US

I take this opportunity of reminding my Antipodes readers that Krauss is the author of a momentous book on physics and philosophy: A Universe from Nothing. It reflects upon humanity's biggest question (which has often driven me crazy... at least for a moment or so): Why is there something rather than nothing at all?
