| | Archimedes’ most famous (though not the greatest) accomplishment was when Hiero became suspicious that a [[crown]] made for him by his goldsmith was diluted with silver. Not knowing what to do, he turned to Archimedes for help. Archimedes realized that if there was silver in the crown it would displace more water than would be displaced by gold of an equal weight. As it turned out, the king's fears were justified; the goldsmith had cheated after all. | | Archimedes’ most famous (though not the greatest) accomplishment was when Hiero became suspicious that a [[crown]] made for him by his goldsmith was diluted with silver.
