This week's Final Word comes from a story about explosions and Manhattan:

"The preeminent transnational community in our culture is science. With the release of nuclear energy in the first half of the twentieth century that model commonwealth decisively challenged the power of the nation-state. The confrontation is ongoing and inextricably embedded in mortal risk, but it offers at least a distant prospect of felicity. The different country that still opens before us is Bohr's open world."

The winner of last week's competition, who identified Stephen Hawking's A Brief History of Time , is Iain Stevenson of London.
