• Prologue. 'An imperial science'; 1. 'An ill-understood effect of induction': telegraphy and field theory in Victorian Britain; 2. Wildman Whitehouse, William Thomson, and the first Atlantic cable; 3. Redeeming failure: the joint committee investigation; 4. Units and standards: the ohm is where the art is; 5. The ohm, the speed of light, and Maxwell's theory of the electromagnetic field; 6. To rule the waves: Britain's cable empire and the making of 'Maxwell's equations'; Epilogue. Full circle.

'Lucid, brilliantly well-informed and replete with fresh insights, Imperial Science is destined to be an indispensable classic. Bruce J. Hunt gives us a rich account of how radical developments in cable telegraphy and the theory of electromagnetism were intertwined, with profound consequences for the everyday lives of millions of people all over the world.'
