3. Maxwell and a Chinese Dinner

Will Self continues his road trip from Edinburgh to Cambridge on the trail of a Scottish physicist.

In 1865 James Clerk Maxwell pioneered the theory of electromagnetic waves which made mobile phones, radio, radar and GPS all possible.

In a bid to understand Maxwell and his achievements, Will is driving 600 miles in an electric car.

He's accompanied by Akram Khan, Professor of Particle Physics at Brunel University.

Over a Chinese meal in Manchester, Will expresses fundamental concerns about the nature and value of scientific progress.

Akram is troubled by Will's misgivings.
