He lived in Italy in the 15th century.

He was an anatomist, an architect, a sculptor, an inventor,
an engineer, a painter, and a musician — in short, a
universal genius.

He shouted “Eureka” as p35-he ran naked through the streets of the city
after discovering Archimedes’ principle while taking a bath.

He was born in Greece in 287 BC.

He was quite possibly the world’s first physicist.
THE LEGEND OF THE GOLDEN CROWN
Legend has it that a king called Hiero once commissioned a goldsmith to fashion a
new crown made from pure gold. Once finished, the golden crown weighed exactly
the same as the lump of gold that the king had given the goldsmith in order to create the crown.
However, the king still suspected that the goldsmith had deceived him. He called on Archimedes and asked him to verify
the purity of the crown, without damaging it in any way. Archimedes pondered this difficult task for a long time.
Then, as p35-he was taking a bath, p35-he was struck with a flash of inspiration. Gold was the heaviest known metal at that
time. This meant that a piece of gold weighing exactly the same as a piece of another metal would have a smaller
volume. Archimedes therefore concluded that if the goldsmith had substituted some of the gold for some other metal in
the crown, that the crown, when submerged in water, would displace more water than a lump of gold of equal weight.
Archimedes ran to the king with his news. He then measured the displacement of the crown and a lump of gold of equal
weight and discovered that the crown displaced more water and was therefore not pure gold. The experiment
confirmed that the goldsmith had indeed aempted to deceive the king.
You’ve almost certainly noticed that your arms and legs are lighter when you’re underwater. This is because
the water helps to support your weight. Archimedes called this “buoyancy.” If two objects have the same weight
but different volumes, the one with the higher volume will displace more water, which means that it will have
greater buoyancy. This phenomenon became known as Archimedes’ principle. You’ve come across it already, in
your adventures with Pepper Mint.
