Etymology: likely stems from the Spanish boyante, present participle of boyar, meaning "to float."

The Greek scientist and jack-of-all-trades Archimedes of Syracuse, or simply Archimedes, was a busy man during his time. Among his advances in physics are the foundations of hydrostatics, statics and an explanation of the principle of the lever. He is credited with designing innovative machines, including the screw pump that still bears his name.

The most widely known anecdote about Archimedes tells how he invented a method for determining the volume of an object with an irregular shape. According to the Roman writer Vitruvius, when Hiero II of Syracuse suspected his goldsmith of cheating him over the making of a votive crown for a statue in a temple, for which he had supplied the gold to be used, he asked Archimedes to devise a test.

As the story goes, he carried out the test while taking a bath by placing the crown in the water and then noticing that the water level rose. This led Archimedes to his famous moment when he apparently ran naked through the street crying "eureka!" (Greek for "I found it!") after he realized he could test the crown by comparing its displacement of water to that of the same weight of pure gold.

Some people believe this is more myth than fact. Archimedes probably used a more scientific approach by balancing the crown on a scale with a gold reference sample, then immersing the apparatus in water. The difference in density between the two samples would cause the scale to tip accordingly. Whatever the method, it is referred to as the Archimedes Principle or more commonly "buoyancy."

Bad joke of the day: How did Archimedes react when he received an invitation to the annual Scientists' Ball? He was buoyant!
