One scientific advancement of the Greeks was medicine. Back then, people thought that disease was God's way of punishing folks. Hippocrates, a famous Greek physician, wrote many medical records. He has been revered for his main work, the Hippocratic Oath which people claim that he did not write. But he is still known as the Greek Father of Medicine.
We probably can't talk about Greek science without stumbling upon Aristotle. He was a student of Plato who was a student of Socrates. He was actually famous for rejected his very own teacher's forms. He wrote numerous treaties but only 31 actually survived. He was considered the father of logic, he thought that everything was to be observed by its structure, not content. One example of his logical thinking was: Men are mortal; Socrates was a man, so he is mortal. Duh! This branch of thinking lasted for quite a long time. His logical reasoning has still lasted to this day.
Whenever you step into a full bathtub, you realize it overflows...right? This principle was discovered by a man named Archimedes. It is called the law of displacement. It shows that whatever volume of the object placed into the water, that is how much water will overflow, to put it in simple words. He also launched ships by himself using the idea of pulleys and levers. One invention had he created was called the Archimedes screw, used to raise rivers up for irrigation. He also made many common weapons such as the catapult. These weapons were used to fight off Roman invasion. In 21 BC, he was captured by the enemies and killed. Another famous mathematician was Euclid, who invented many basic rules of math. In addition to Euclid, there was also Pythagoras, probably one of the most famous mathematicians of all time for his famous geometrical right triangle formula, a²+b²=c². He also invented pi, and used it to find many parts of a circle including the circumference.
Thales was quite the thinker! Born in what is now modern day Turkey, he spoke Greek. As a young boy, he traveled all over to study with Egyptian or Babylonian scientists. As he became older, he was the first scientist that did not believe that everything was connected to God and not everything was just 'because of God.' He thought that everything had a scientific explanation and it turns out that he was right, He thought that every living organism was water based. He was correct but every one of those things was actually created by electrons and plutons. But one of the things he was known for is that he understood that the Earth was round and the moon was actually lit up by the sun's reflection. According to Herodotus, a famous historian, Thales was the first person to successfully predict an eclipse. Thales was also known as a famous mathematician. He proved many geometrical theorems that are very commonly used, All thanks to Thales, we know the correct astronomy and geometry!
