Archimedes, the Greek mathematician, is probably most famous for the story of King
Hieron II of Syracuse and the gold crown. The king a (want) wanted to give a
gold crown as a gift to the gods, and b (give)
a carefully weighed
amount of gold to a goldsmith. The man c даю i(produce)
a beautiful
crown, but the king was worried that the craftsman d (not use).
all the
gold to make the crown. Dishonest craftsmen often e (mix)
gold with
silver, which was cheaper, but the king could not find a way of proving that the man
f(do)
this. He g (ask)
Archimedes to solve the problem. Archimedes
h (know)
that gold and silver have different densities. The problem was that nobody could
calculate the mass of an object like a crown. While Archimedes i (think)
about this problem,
he decided to go to the public baths to relax. While hej (climb)
into the bath, he
k (notice)
some water on the floor. It! (spill).
over the side of the bath, and he
m (realize)
that he n (solve)
-the problem by accident. The total amount of
water that o (spill)
out of the bath must be the same as the volume of his body. He could use a
piece of pure gold and calculate its volume, and then test the crown and see if it was the same. According to
the story, he p (jump)
straight out of the bath and q (run)
down the street
calling 'Eureka - I've found it.' The goldsmith soon r (admit).
that he s (cheat)
the king, and was punished. Archimedest (discover)
a principle of buoyancy.
