Why in the past Muslims
ruled the world even India for a 1000 years ??? Why ??? because of their knowledge skill were way better than the rest of the world.
Islam teaches us to Seek Knowledge from cradle to grave.
Today Muslims have become greedy, ignorant and selfish.
Some Examples:
Abu al-Wafa Buzjani
Abu al-Wafa was a Persian, mathematician, and astronomer of medieval age. He was born in 940 AD in Buzhgan, Iran. His work on trigonometry and arithmetic opened the gate of knowledge for the scientists of medieval age. Many renowned Muslim scientists were Persians.
Abu al-Wafa contribute in trigonometry by introducing secant and cosecant functions. He also compiled a table of sines and tangents at the angel of 15 degree. Additionally, Abu al-Wafa was the first person invented and used wall-quadrant to observe the sky. For this inventions his name “Abu Wafa” was kept on one of the moon’s crater. Google changed their doodle in 2015 to honor Abu al-Wafa.
Inventions:
- Introduced secant and cosecant functions.
- Gave values of sine and tangent at 15 degree.
- Build a quadrant (astronomical instrument).
Banu Musa Brothers
Unlike Muslims scientists in this list, Banu Musa is not just one person but it is the group of 3 brothers – Abu Jafar, Abu al-Qasim, and Ahmad. Their work on mathematics and mechanics was frequently quoted by scientists of that time. Their treatise on mathematics (The Book of the Measurement of Plane and Spherical Figures) gave the numerical value of area and volume. Their famous treatise was (The Tricks Book) on mechanics consists of 100 mechanical devices. While in astronomy they measured the length of a year – 365 days 6 hours.
Inventions:
- First to give numerical values of area and volume.
- Measured the length of a year.
Al-Battani
He was among few Golden Age Muslim scientists and astronomers that featured by many European medieval age scientists. Al-Battani was born in c. 858 AD in Harran, Turkey. He was famous mathematician and astronomer. His treatise on astronomy – Kitab az-Zij – he calculated a year as being 365 days, 5 hours, 46 minutes and 24 seconds which is 99% accurate. Among his best-known works, the use of sines and tangents (trigonometry) in calculation got much fame.
Inventions:
- Refined the value of a solar year, which is still 99% accurate.
