How Did Alberoni Measure The Earth? Technology Is Amazing
There were great people who performed remarkable tasks without modern instruments and computers and developed the most accurate measurements of the earth, the formulas of alchemy, and the principles of mathematics, on the basis of which the building of science stands today. Surprisingly, today NASA uses its spacecraft and state-of-the-art technology to calculate the radius of the Earth at 6371 km, which Abu Rihan al-Biruni measured with amazing accuracy almost a thousand years ago today, which is 6335 km. Now the question arises,
How Did Al-Biruni Measure This?
Before al-Biruni, Mamun al-Rashid assigned two groups of experts to measure the earth. These experts traveled north and south in the desert and measured the Earth’s radius by repeatedly measuring the angle of the sun at noon. The first thing to know about Al-Biruni is who he was and how he did it all.
The famous researcher and scientist Abu Rayhan Muhammad bin Ahmad Al-Biruni alias Al-Biruni was born on September 4, 973 in a village on the outskirts of Khwarizm, outside and was called Al-Biruni after him. Al-Biruni was a contemporary of Bo Ali Sina. Al-Biruni’s patrons in Kharazm, the Iraqi government, came to an end, so he set out for Jirjan. Completed his great book “The Remains”. When conditions became favorable, al-Biruni returned home and met the great Bo Ali Sina at the court.
Why His Mother Used To Call Him Abu Rehan:
Alberoni was a lover of natural scenery from the beginning. Collecting flowers and plants was his hobby, that’s why his mother used to call him Abu Rehan. Al-Biruni’s father ran a small business, but his sudden death forced Al-Biruni’s mother to make a living by collecting wood from the forest for herself and her son. Al-Biruni used to share his mother’s hand in this work. Al-Biruni mastered the Greek and Syriac languages at the age of 14 and learned a great deal about the plant world from Greek knowledge. His interest in the physical sciences grew. The Greek scholar, before returning to his native Greece, took Al-Biruni in the service of the astronomer and mathematician Abu Nasr Mansour Ali (who was the prince of the Khwarizmi dynasty). Abu Nasr built a separate house for al-Biruni and also set a stipend. Abu Nasr taught al-Biruni astronomy and mathematics every day. Abu Nasr made al-Biruni a disciple of the famous mathematician and expert Abdul Samad.
Astrolabe To Find Out The Angles:
Al-Biruni chose a laboratory to measure the angle of the horizon. The second step after selecting the hill was to measure the height of the hill. To do this, al-Biruni stood at some distance from the hill and found the first angle (degree 1) of the top of the hill from the ground, then determined the distance, and the second angle (degree 2), then these two known angles and Find the height of the hill by giving the value of the distance between them in the relevant formula. Al-Biruni used a device called Astrolabe to find out the angles.
The stroller is a large dial device with a clock-like knob in the middle. To find the angle of the top of the hill from the ground, Alberoni looked at both ends of the needle-like navel and the top of the hill in an alignment. The way the gun is shot is targeted, when all three appear in alignment, the angle written on the dial notes the angle.
The Greatness Of Al-Biruni:
Al-Biruni wrote excellent books on mathematics, anatomy, history, and geography, which are still read today. One of them is the famous “Kitab-ul-Hind”, in which Al-Biruni has written with great research the religious beliefs of the Hindus, their history, and the geographical conditions of the Indian subcontinent. He authored more than 150 books and dissertations on mathematics, anatomy, physics, history, culture, world religions, geology, chemistry, and geography. In view of Al-Biruni’s exploits, a lunar eclipse has been named “Al-Biruni Crater”.
