Greek Architecture

The Parthenon was a temple to Athena built on top of the highest hill in Athens, the Acropolis (Acropolis means High City). In the Late Bronze Age, about 1300 BC, the Acropolis had been where thekings of Athens lived (like Theseus in the myth), and where everybody went to defend themselves when there was a war. But after the Dark Ages, the Athenians had no more kings to rule them. Instead they had an oligarchy, and so there was no king to live on the Acropolis. Instead, the Acropolis became sacred to the goddess Athena, and the Athenians built her a temple there.

Greek Inventions

ionThe MIT Daedalus was a human-powered aircraft which, on 23 April, 1988 flew 74 mi (119 km) from Iraklion Air Force Base on Crete, crashing in the ocean just short of the island of Santorini in 3 hours, 54 minutes. Despite the fact that the aircraft crashed short of its goal, some people consider this flight to have set a distance record which stands to this day. The craft was named after the mythological character Daedalus.

Greek Inventions


Thermometer
We use the thermometer every day in our lives and climatology as we know it would be very different without this simple device. The thermometer is a very old invention that dates back to the Greeks of Alexandria who discovered that air expanded when heated. Philo of Byzantium, who lived 2,000 years ago, made a basic thermometer that used this concept. Roughly 1,600 years later, Galileo would use this same concept and put a scale on it to help distinguish temperature so that people could know how hot or cold it was on any given day of the week.
