EUREKA
You
all know the story of Archimedes, the famous Greek mathematician.
After taking a bath, he suddenly got out and ran through the streets
of Syracuse, shouting: “I found it, I found it!”
What
did he find out? When he lowered himself in the bath, he suddenly
realized, that the water rose, according to him slowly descending.
This was not something at random, like swimming in a river. But it
could me measured and this would happen according to a natural law.
A low later named after him, which says, that the water level rises
according to the volume, that is put in.
But
why was Archimedes so ecstatic? He had found the solution to a major
controversy in this harbortown in Southern-Italy. Syracuse was Greek
and ruled by a couple of powerful families, who appointed a
so-called “dictator”. There was a problem at his court. The
Dictator had ordered a golden vessel for one of the temples in
Syracuse. It was ordered from a famous goldsmith. When the vessel
arrived, the dictator became suspicious. He suspected the goldsmith
of cheating. Silver was less valuable and he thought that the golden
vessel was largely of silver. But how to prove this.
Well,
this is where Archimedes got in. Gold was heavier, than silver; so
to reach the agreed weight, the volume would increase. So proving
that the artist had stolen some gold. The Dictator's intuition
proved right, the vessel contained silver. The story does not tell,
what happened to the gold-smith. Archimedes was a practical man. His
theoretical insights made it possible to develop all kinds of
weapons. Syracuse was besieged by the Romans, but the Roman fleet
could not approach the city walls. Under the supervision of this
genius, in this respect surpassing Leonardo da Vinci., large mirrors
were build, that set the sails on fire. Local historians describe
cranes, that lifted the enemy ships out of the water.Some say he
invented “Greek fire”, a chemical substance, that even burned on
water.
But
Romans never give up and in the end, Syracuse fell and the
legionnaires looted the town. Archimedes was killed during this
raid. A young soldier stabbed him. Because he did not want to be
disturbed during his calculations.
Just
a few notes of Archimedes survived, so it was a sensation, that a
complete book surfaced. In a monastery, the monks ran out of
parchment. They scraped off an old text (the one of the Greek
mathematician) and turned it into a prayer book. Recently pecial
X-ray-techniques made the original text visible. Once again his
genius had endured time.
Another
genius in the “Greek-timeframe” was Heron of Alexandria. He
invented a steam engine. He used this power to open and close
temple-doors, to move statues and to even make the Gods fly. It is,
that he didnot put wheels under it. A railway from Alexandria to
Jerusalem would be possible.
In
the beginning of the 20th century another “Eureka-moment”
took place. A diver near the small island of Antikythera was
searching for sponges, when he suddenly surface. He cried out that
“the sea-floor is covered with corpses!” The sponge divers had
found the wreck of a Roman ship, which sank about 200 AD. The vessel
transported stone, marble and bronze statuettes. Looted in Greece
and on their way to Rome, to be added to its glory. Fortunately, the
expedition went wrong. Apart from the statues, the divers found a
block of coral-stone, with strange metallic pieces in side. The
stone was kept in the cellars of the museum in Athens for a long
time. This artifact was X-rayed in the last century and it became an
overnight sensation. Inside the stone a metallic clock like object
was found. Later it proofed to be an astronomical device of great
ingenuity. Still the question remains: did the Greeks posses the
brains and the technology to these seafaring tools and could also be
used for calculating the next Olympics. Where there more of them or
was this an exception? Was it a legacy of Archimedes or his
students. If this was “ common technology ”, we need a
completely different look on the seafaring and trading of the Greek.

Toeval
bestaat niet.
Toeval
is een ander woord voor onwetendheid. Het niet hebben van kennis van
de kleine en grotere verbanden, waar we deel van uitmaken.
Onwetendheid is de bron van ieder lijden.
