Which country has the best brains?

Over the past week, the Nobel prizes have been awarded in chemistry, medicine, peace, physics and literature.

The awards are an annual ritual celebrating human intellectual endeavour that began in 1901. They were set up by Alfred Nobel, a Swedish inventor and arms manufacturer, who requested in his will that his fortune be used to create a series of prizes for those who confer the "greatest benefit on mankind".
