Two things you might not know
- Its discoverer first offered it anonymously in a small Soho shop in April 1803; a rival claimed it was an alloy of platinum and mercury.
- Named after an asteroid; a mainstay of catalytic converters, it absorbs hydrogen so well it was key to late-1980s cold fusion experiments.
