Science in Antiquity: Part 4

Many modern people have a very limited view of history. They can only see or think about five or ten years into the past. They see history as boring and they think of the ancients as ignorant and backward. This was actually not true. What the ancients lacked was the modern accumulation of facts. An ancient Israelite would have been very puzzled and culture-shocked to have been dumped into the modern world, but he or she could have eventually learned to drive a car or to cook on a stove or to use a cellphone.

The ancients were just as intelligent as we are but the accumulation of scientific facts had not yet reached a critical point. Human knowledge took centuries to double, fact by fact. As knowledge accumulated, the rate of accumulation began to speed up. Every answer exposes a new question. Buckminster Fuller spoke of the Knowledge Doubling Curve which was relatively flat for centuries, then began a slow climb, and then went into an explosive upward thrust.

By the end of the 19^th Century, knowledge was doubling once per century. By about 1945, the rate of doubling was about every 25 years. By 1982, the rate was about every 12-13 months. By 2020, the doubling was occurring about every 12 hours. With at least 50,000,000,000 devices now operating and with the rise of artificial intelligence, the rate may now be in minutes.

 

Ca 205 BC/BCE: In 1900 the Antikythera Mechanism is discovered off the island of Antikythera. It is a mechanical model of the solar system (with the then-known five planets) and an astronomical calculator. It can predict solar and lunar eclipses.

212 BC/BCE, WBD: Death of Archimedes, Greek mathematician, in the losing defense of Syracuse (modern Siracusa/Saragusa, Italy) against a Roman assault during the Spring of 213 until the Autumn of 212. The defense of the city included the use of weapons developed by Archimedes. His work included hydrostatics, mechanics, and the invention of a screw device for raising water.

230 BC/BCE: 1. Death of Aristarchus, who declared that the Earth revolves around the sun. He suspected that the stars were suns like ours.

Ca 240 BC: In Cyrene (modern Shahhat, Libya), Eratosthenes calculates the circumference of the Earth.
