She required a locked room in every house. She moved with two hundred boxes. She took the children to slaughterhouses, photographed Dali and Kirk Douglas, and left 150,000 negatives mostly undeveloped. Meet Vivian Maier: the nanny who never looked.

29 August 1831. Faraday connects a battery to a coil on an iron ring. The needle on a second coil jumps, falls back to zero while the current still flows, and jumps the other way when he disconnects. Every generator and transformer is that ring.

April 1820. During a lecture, Ørsted brings a compass next to a wire carrying current and the needle swings sideways: not towards the wire, not away from it, across it. Within weeks Ampère measures the force between two currents.

1800. Volta stacks discs of zinc and silver with brine-soaked cloth between them and gets, for the first time, a current that does not stop: the battery. It began with Galvani's frog legs twitching on a balcony in Bologna.

1785. Coulomb hangs a needle from a silver wire so fine that one degree of twist measures a force of a few billionths of a newton, and finds that the force between charges falls with the square of the distance. Franklin's rod came first.

1746. Pieter van Musschenbroek charges the water in a glass jar and touches the wire. The shock is so violent he writes that he would not take it again for the kingdom of France. The Leyden jar: the first device to store electricity.

1600. William Gilbert carves a lodestone into a sphere, moves a small needle over it and watches it dip exactly as compass needles dip at sea. The Earth is a magnet. Six hundred pages of experiments: De Magnete, the first modern book of physics.

1861. Maxwell works out how fast a disturbance travels through his model of empty space: 310,740 km/s, a number two Germans had measured five years earlier with a Leyden jar and a magnetic needle. Fizeau's speed of light: 314,858 km/s.

He threw the gold sovereigns into the snow and kept the twelve-pound banjo. He crossed 800 miles of ocean in a 22-foot boat, then climbed uncharted mountains with screws in his boots. The station manager asked who he was. His name was Shackleton.
