Medieval African science
How Islam helped African science
Thanks to their common religion, Islam, all of these men were able to communicate in Arabic. So they could find out about new treatments and ideas. And they frequently travelled to visit each other in Africa. African scientists went to West Asia and India and even sometimes to China to find out more about the world.
Al Jazzar and Ibn Ridwan
Al Jazzar was a doctor in Kairouan about 950 AD, under Fatimid rule. He wrote a medical textbook describing different diseases and how to treat them. Ibn Ridwan, an Islamic African astronomer, also worked in Kairouan just a little later. He left us the best description of a great supernova, first observed in 1006 AD.
Ibn Bajjah’s astronomy and physics
Another Islamic African scientist was Ibn Bajjah, who worked in Morocco in the 1100s AD under the Almohads. Ibn Bajjah wrote a book about sexual reproduction of plants, which later influenced Ibn Rushd. Ibn Bajjah also saw that the Milky Way was made up of thousands of stars close together, and he made contributions to the development of the laws of motion.

Al Idrisi’s map of the world
About the same time, and also from Morocco, al Idrisi created an up to date map of the known world (Europe, Asia, and North Africa), and wrote an account of some Almohad explorers who sailed west on the Atlantic ocean perhaps as far as the Sargasso Sea (but still a thousand miles from North America).

Marijuana and opium in African medicine
Around the same time (or maybe earlier), East African doctors learned from Indian doctors to grow and use marijuana, possibly inventing the water pipe to smoke it in. They probably also began to use opium as a medicine.
South Africa and Central Africa
In South Africa and Central Africa, people didn’t have so much contact with other places, and here women kept on being involved with science and medicine. Among the San, for instance, both women and men learned to identify hundreds of plants that they could use for medicine.
