## Why is the Tusi couple important?

The Tusi couple is considered by historians of astronomy a key element of the Copernican heliocentric system. Historians showed that Persian astronomers of the 13th century from the Maragha school in southern Azerbaijan came very close to the discovery of the heliocentric Copernicus planetary system.

What is the Tusi couple used for?

The Tusi couple is a mathematical device in which a small circle rotates inside a larger circle twice the diameter of the smaller circle. Rotations of the circles cause a point on the circumference of the smaller circle to oscillate back and forth in linear motion along a diameter of the larger circle.

### How did Copernicus model of the solar system explain retrograde motion?

In the 1500s, Copernicus explained retrograde motion with a far more simple, heliocentric theory that was largely correct. Retrograde motion was simply a perspective effect caused when Earth passes a slower moving outer planet that makes the planet appear to be moving backwards relative to the background stars.

When was the Tusi couple created?

The Tusi couple was first introduced in the 13th century by Nasir al-Din al-Tusi (1201–1274) (a Persian polymath: architect, astronomer, mathematician, philosopher, physician, scientist, theologian) in his Tahrir al-Majisti = Commentary on the Almagest (1247) as a model for the latitudinal motion of the inferior …

## Did Copernicus invent the Tusi couple independently?

Historians have considered the possibility that Copernicus might have invented the Tusi couple independently of al-Tūsī, but that doesn’t seem too likely, especially since Copernicus uses the same lettering labels as al-Tūsī, which are not the letters that a Western astronomer would normally use.

Which was a contribution to astronomy made by Copernicus?

He introduced the heliocentric model of the solar system. Before, the earth had been believed to be the center. He stated that the seasons, the sun’s rise and fall each day,the planetary movement, and the movement of the stars were all caused by earth’s rotations. He established the orbit of the planets around the sun.

### What was the greatest contribution to astronomy made by Copernicus?

In it, Copernicus established that the planets orbited the sun rather than the Earth. He laid out his model of the solar system and the path of the planets. He didn’t publish the book, however, until 1543, just two months before he died.

What was Tusi best known for?
