Do you use a camera? Do you know how we see? Perhaps you use or have used the scientific method? The man behind discovering ideas behind these things and more is Ibn al-Haytham or Alhazen (his name in Latin). He was born in Basra, Iraq in the 10th century. He was a scientist, mathematician, and engineer. He lived during the Golden Age of Islam and benefited because of the knowledge being studied and shared.
When looking at the Middle Eastern and North African cultures, we tend to look at the history. What they did with math and science is amazing and often overlooked in our traditional education. With all the discussion of STEM floating around a look at Ibn al-Haytahm is perfect. We discovered a bit about him with a National Geographics Kids book: Ibn al-Haytham: The Man Who Discovered How We See by Libby Romero.

We tried to make our own camera obscura and repeat his experiment.
We used a show box with one end having wax paper on one end and a hole on the other. It did not work quite as well as his did, but we were able to see the flame a bit upside down.
Now the interesting things is that al-Haytham ended up in Cairo. I have read mixed stories as to how and why he ended up in Cairo. The caliph there however did want him to solve the flooding problems of the Nile. This was not resolved until the 20th century though. At one point al-Haytham declared he had gone mad and the caliph forced him to stay in his home until the caliph dies. During this time it is said that al-Haytham did some experiments with vision and discovered how the eye sees images upside down and our brains turn them correctly. He also saw that images were easier to see with a smaller hole thus why our cameras are the way they are.
The only other children's book with Ibn al-Haytham that we could find at our library network is Arab Science and Invention in the Golden Age by Anne Blanchard and Emmanuel Cerisier. This book shared his look at how light could bend and suggested the simple experiment of putting a stick in a glass of water.
I could not get the perfect angles to really show it at the water's surface but the lines in our glass really helped show it at the bottom. Al-Haytham studied light, rainbows, irrigation and more. He attempted to produce a rainbow in his laboratory but was not able to. The creation of a rainbow was fully explained in the 13th century by al-Farisi in the Muslim world and Dietrich de Freiburg in Europe. So as you take a look at the Middle Eastern and North African cultures be sure to take a look at some of the amazing discoveries they made and knowledge they shared during the Golden Age of Islam.
