A sextant.the sextonan astrolabe
its a compass of course! that can be used to map out the sun,moon and other types of planets
The sextant.
Abu Rayhan al-Biruni invented Orthographical astrolabe in the 11th century.
Muslims were great scientists. Muslim scientists who studied the heavens perfected the astrolabe. Sailors used it to tell what longitude:latitude and where they were on the Earth. When they used the astrolabe to measure the Earth, they realized that it was round. The Muslims were the first to discover this. They experimented with metals and kept records of their work. As a result, they classified themselves as chemists, or the founders of chemistry. Also, Al-Razi was the first to categorize animals, veggies, and minerals. He wrote books for doctors to help them to identify diseases.
The astrolabe must be level in order to read the altitudeproperly.
When the astrolabe is leveled, it allows the user to accurately measure the altitude of celestial objects above the horizon. This information can then be used to determine one's latitude on Earth. By aligning the astrolabe and leveling it properly, the user can obtain precise readings for astronomical navigation.
To determine the altitude of an object in the sky using an astrolabe, you would align the sighting arm with the object. Then, you would read the degree scale on the astrolabe where the sighting arm intersects it. This reading would give you the altitude of the object above the horizon.
compass, and the astrolabe
The astrolabe is an ancient astronomical instrument used to determine the altitude of celestial bodies, such as stars and planets, in relation to the observer's position on Earth. It consists of a rotating disk with a sighting mechanism that allows users to measure the angle between the horizon and a celestial body. Navigators and astronomers in the past used the astrolabe for celestial navigation, timekeeping, and determining the positions of stars.
astrolabe=star+mechanical clock
== == the astrolabe is to find the altitude of a stellar object
The word astrolabe is a noun. The plural is astrolabes.
Astrolabe: star + Mechanical Clock
An astrolabe is an old instrument used to calculate the position of celestial bodies. Here are some sentences.I found an antique astrolabe in an old store.An astrolabe was used before the sextant was invented.Polish that astrolabe so it doesn't tarnish.
An astrolabe helped sailors because it could determine any direction based on the position of the stars. This is why the astrolabe helped sailors.
The scientist used an astrolabe to find the altitude of the sun and stars.
