Will Self concludes 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 has driven 600 miles in an electric car.
