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.

Happy birthday to British #engineer, #mathematician, #physicist & #inventor Hertha Ayrton (1854-1923). I’ve shown her in my #linocut with a diagram of the dividers from her 1st of 26 (!) patents, one of her diagrams about the origin & growth of ripple marks & one of her diagrams of an electric arc lamp (a subject on which she literally wrote the textbook).
Born Phoebe Sarah Marks, she was the 3rd 🧵https://minouette.etsy.com/listing/966154261
