Astronomy...
Compasses help sailors determine the direction in which they are traveling by detecting the Earth's magnetic field. Astrolabes were used by sailors to determine the altitude of celestial bodies, such as the sun or stars, which helped them navigate by calculating their position relative to these reference points.

No, the astrolabe is no longer commonly used for navigation or astronomy. It has been largely replaced by more modern and accurate tools such as GPS devices and telescopes. Astronomers and historians may sometimes use astrolabes for educational or historical purposes.
An astrolabe is typically made of metal, such as brass, that is engraved with various markings for celestial navigation. The device also includes a rotating arm called an alidade, which is used to measure the altitude of stars and celestial bodies. Some astrolabes may have additional components made of wood or other materials.
The magnetic compass was the European invention that helped explorers determine the directions they were traveling by using the Earth's magnetic field. This device aided navigation by pointing towards the magnetic North Pole, enabling sailors to maintain their heading even when out of sight of land.

they where used to navigate using sun and stars :)
well I know that they did not use Viking ship designs. 3======D 0:

Astrolabes were made using metals such as brass. This gave the toolsÊadded strength among various journeys but weighted down their overall usefulness.
They are called "quadrants".
only in quadrants 2 and 3
Roman numbers are used in naming the quadrants as it will be easy to distinguish between the various quadrants as all the other dimensions in that quadrant are in numeric form .So,to avoid any error or redundancy .There are 4 quadrants : quadrant I,quadrant II,quadrant III and quadrant IV.
The axes create the quadrants.
The Cartesian plane is divided into 4 quadrants
There are 4 quadrants in a circle
