Surgery
Around the year 1,000, the celebrated doctor Al Zahrawi published a 1,500 page illustrated encyclopedia of surgery that was used in Europe as a medical reference for the next 500 years.
Coffee
Now the Western world's drink du jour, coffee was first brewed in Yemen around the 9th century.
University
In 859 a young princess named Fatima al-Firhi founded the first degree-granting university in Fez, Morocco.
Algebra
The word algebra comes from the title of a Persian mathematician's famous 9th century treatise "Kitab al-Jabr Wa l-Mugabala" which translates roughly as "The Book of Reasoning and Balancing." Built on the roots of Greek and Hindu systems, the new algebraic order was a unifying system for rational numbers, irrational numbers and geometrical magnitudes. The same mathematician, Al-Khwarizmi, was also the first to introduce the concept of raising a number to a power.
The crank
Many of the basics of modern automatics were first put to use in the Muslim world, including the revolutionary crank-connecting rod system. By converting rotary motion to linear motion, the crank enables the lifting of heavy objects with relative ease. This technology, discovered by Al-Jazari in the 12th century, exploded across the globe, leading to everything from the bicycle to the internal combustion engine.
Hospitals
"Hospitals as we know them today, with wards and teaching centers, come from 9th century Egypt," explained Hassani. The first such medical center was the Ahmad ibn Tulun Hospital, founded in 872 in Cairo. Tulun hospital provided free care for anyone who needed it -- a policy based on the Muslim tradition of caring for all who are sick. From Cairo, such hospitals spread around the Muslim world.
