Science in Antiquity: Part 2

 

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 not 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 19th 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.

 

9 March 5 BC/BCE: Chinese astronomers describe a comet which they observed.

24 BC/BCE: Strabo visits Thebes (modern Luxor/al-Uqsur, Egypt). On this trip (24-20), he finds the ruins of Heliopolis (the biblical On). Genesis 41:45. He described the Earth as a sphere and said gravity pulled things to the center.

(b. ca 25 BC/BCE – d. ca 50 AD/CE) Aulus Cornelius Celsus is a Roman medical encyclopedist who wrote about subjects including skin disorders, fevers, kidney stones, eye anatomy, dentistry, jaw fractures, cancers, diet, surgery, and medicines. He taught correctly that fevers were the “effort of the body to throw off some morbid cause.”

10 May 28 BC/BCE: Chinese astronomers recorded the earliest known dated record of a sunspot, a black spot on the sun. Exactly how the sunspots were viewed is not known, since telescopes were not invented until the 1570’s and direct viewing of the sun will damage the eyes.

78-37 BC/BCE:  The Han Chinese genius, Jing Fang, is a music theorist, mathematician, and astronomer. He explained lunar and solar eclipses and musical octaves.

100 AD/CE: 1.  The mathematician Theon of Smyrna says that the Earth is a sphere.

Ca 20 AD/CE:1.  Birth of the Greek scientist, Hero of Alexandria, who did work in theoretical mathematics, mechanics, and physics.  He studied the science of light reflection and invented a rotary steam engine and several pneumatic devices.

              2. Geminus of Rhodes studies astronomy and writes The Theory of Mathematics.

8 AD/CE: Chinese astronomer Liu Xin calculates the solar year as 365.25016 days. He calculates pi as 3.154

The Orbit of the Sun


“His going forth is from the end of the heaven, and his circuit unto the ends of it: and there is nothing hid from the heat thereof.” Psalm 19:6 (This verse is referring to the sun.)

Many critics of the Bible said that this verse describes a geocentric view, ie; that the sun revolves around the Earth. Since the sun was thought to be stationary, this would be an “error” in the Bible.  Modern astronomy has unintentionally resolved this supposed “error.”

The sun and the solar system are moving as a group in a circular orbit around the center of the Milky Way galaxy at a rate of about 220 kilometers per second.  An orbit of the galaxy takes about 225,000,000 years.  This is called a cosmic year.

Science says that the sun is about 5,000,000,000 years old, so it would have completed about 20.4 orbits if the dating is correct.
