Famous Greek Scientists

#17. Hipparchus (190 BC-120 BC): The Father of Astronomy

What makes Hipparchus famous?

Hipparchus was one of the most outstanding scientists in ancient Greece. He is best known for his theories concerning the solar and lunar motions.

Hipparchus lived during a time characterized by astronomical, geographical, and mathematical discoveries.

He is widely regarded as one of the most influential figures in ancient astronomy because he developed methods for measuring solar motion accurately and precisely. 

Hipparchus also devised several methods for calculating distances between stars and planets on Earth’s surface using trigonometry. He could reliably predict eclipses and even discovered the precession of the equinoxes—the slow change in the direction of Earth’s axis over time.

But one of Hipparchus’ most remarkable achievements was likely his star catalog. This was an extensive list of stars visible to astronomers during that period. Hipparchus’s catalog would later be used by many scientists when creating their own lists of stars visible from around the globe.

What makes Galen famous?

Galen was a Greek physician in the Roman Empire who is best known for his contributions to pathology, pharmacology, physiology, neurology, and anatomy. He used animals such as pigs and apes to understand the human body. 

Galen’s work influenced medicine for centuries after his death. However, many of his beliefs about how the body works were incorrect or incomplete. 

This can be seen in the theory of humor: he believed one’s health depended on keeping four humors in balance—blood, phlegm, yellow bile, and black bile.

What makes Aristarchus famous?

Aristarchus of Samos is the guy who thought up the idea that our planet revolves around the Sun. This Greek astronomer lived in Samos, an island in modern-day Turkey.

Aristarchus is best known for his heliocentric model of the universe, which states that our planet revolves around the Sun instead of the Earth being at its center. 

This marked a shift from the geocentric model—which had been popular since ancient times. It changed how people viewed their place in the universe forever.

Many people rejected Aristarchus’ theory at first. But his ideas eventually gained traction and became widely accepted by scientists and philosophers.

What makes Menaechmus famous?

Menaechmus was a Greek mathematician who came up with the solution to a problem that had been troubling mathematicians for centuries—the Delian problem. He also discovered conic sections—hyperbolas, parabolas, circles, and ellipses.

Menaechmus was Plato’s friend, and other scientists called him “the master.” His accomplishments are so impressive even though he lived over 2,000 years ago.

But despite all this, Menaechmus doesn’t get nearly as much attention as other Greek mathematicians like Euclid or Pythagoras.

What makes Claudius Ptolemy famous?

Claudius Ptolemy was a Greek polymath who was born in Egypt. He’s best known for developing the geocentric model, which means that he believed Earth was at the center of our solar system.

His work made it possible for other scientists to correctly predict astronomical phenomena like eclipses, which were important back then.

Ptolemy also wrote an encyclopedia called the Almagest, which contained star catalogs and information about planetary motions. The work was so influential that it remained the standard astronomy text for over a 1000 years.

What’s the best Claudius Ptolemy quote?

“Everything that is hard to attain is easily assailed by the generality of men.”

What makes Pythagoras of Samos famous?

Pythagoras of Samos was a Greek philosopher known for making incredible contributions to science and mathematics.

This ancient Greek scientist established a school in Italy that consisted of the Pythagoreans.

This group of ancient Greek philosophers lived by a strict code of silence. They believed their bodies were mere vessels for their souls, which would be reincarnated after death.

Pythagoras also thought that numbers could explain everything in the universe. He believed that certain numbers had special powers and qualities.

Pythagoras made contributions to science. He developed the Pythagorean theorem. This says the sum of the squares of two sides of a right triangle equals the square of their hypotenuse. Pythagoras also came up with the Pythagorean tuning and theory of proportions.

We still use many of the concepts attributed to the Pythagoras of Samos. He remains one of the most influential ancient Greek scientists.

What’s the best Pythagoras quote?

“The soul of man is divided into three parts, intelligence, reason, and passion. Intelligence and passion are possessed by other animals, but reason by man alone.”
