Al-Battani Facts
Al-Battani (858 CE to 929 CE) is the more common name of Arab astrologer, astronomer, and mathematician Abu?AbdAllahMu?ammad ibn Jabir ibn Sinan al-Raqqi al-?arrani al-?abi? al-Battani. Despite having only rudimentary early tools, Al-Battani is best remembered for being the first to determine the most accurate length of the solar year.
Interesting Al-Battani Facts:
Very little is known about Al-Battani's life, which is interesting because even later astronomers like Copernicus knew of him and quoted his writings.
It is known that he was born in Upper Mesopotamia in what is now modern-day Turkey.
He lived and did most of his work in a part of Syria.
His father was a craftsman of scientific tools, which may have contributed to his early interest in science.
Certain parts of Al-Battani's name suggest that he was of Sabian heritage, but also implies that he was a Muslim.
There is some suggestion that he was also a member of the nobility, but that hasn't been confirmed historically.
Al-Battani was able to improve on the earlier calculations conducted by Ptolomy, what were then considered true about the solar year.
Some theories suggest that he was simply in a better geographical location to more accurately track and record the earth's movement, which also led to his more accurate calculations of the equinoxes and the direction of the sun's apogee.
In the field of mathematics, Al-Battani made important contributions to trigonometry, as he is believed to be one of the first to introduce sines and tangents.
He compiled entire tables of calculations for tangents, cotangents, secants, and cosecants.
Al-Battani's most noted book is the Kitabaz-Zij, a book of astronomical tables, whose original manuscript is stored in the Vatican library.
It has been translated many times since its writing and has been referenced by a number of great scientists over the centuries, including Tycho Brahe, Kepler, and Galileo.
Key honors have been bestowed on Al-Battani, including having a crater on the moon named after him, as well as being immortalized on the popular Star Trek television series with an Excelsior class starship named after him.
