"[T]he textile men who dabbled in linear motors made a real contribution... and while they were probably unaware of each other's inventions, it seems probable that some of their work was known to later workers in other fields. If only some of the textile men had been aware of the potential for linear motors in those other fields, the 'Second Age of Topology'... might well have started earlier, just as the invention of the induction machine might have occurred in the 1830s had not the inventors of that time been blinded by the demand to generate 'battery-like' current."
