AUTOMATION has taken over industry
During the early part of the era known as the golden age of Islamic science, from the 8th to the 13th century C.E. and beyond, Middle Eastern scholars translated into Arabic scientific and philosophical texts that preserved the works of such renowned Greeks as Archimedes, Aristotle, Ctesibius, Hero of Alexandria, and Philo of Byzantium. * Having these and other sources, the Islamic Empire
Those machines, says historian of technology Donald Hill, could “continue working for long periods

These automatic systems had much in common with modern machines. However, “they used mainly water under pressure rather than electronics, but many of the operating principles are the same,” says science writer Ehsan Masood.

In 1206, Ibn al-Razzaz al-Jazari completed his work, sometimes translated Compendium on the Theory and Practice of the Mechanical Arts. It has been called “a study in systematic machine design.” Some of al-Jazari’s technology went far beyond that published by the Banu Musa, and his descriptions and diagrams are so detailed that modern engineers can recreate his devices.
Al-Jazari’s book illustrates water-raising devices, water clocks, candle clocks, water dispensers, musical automatons, and a pump that converted the rotary motion of a waterwheel into the back-and-forth movement of a piston that pumped water with great force. Historians give al-Jazari the credit for designing hydraulic pumps three centuries before the same basic design appeared in the West.
Al-Jazari also produced whimsical, yet functional, clocks. The one illustrated here has been reconstructed in a Dubai shopping mall. The timing mechanism is a perforated bowl that sits in a water reservoir inside the elephant’s belly. The bowl becomes full in 30 minutes and then sinks, triggering a series of actions that utilize ropes and balls that are released from the “castle” on the elephant’s back. When the half-hour cycle ends, the water bowl is automatically refloated, and the process starts over. This device and other automatic machines attributed to al-Jazari have earned him the title “father of robotics.”
The story of man’s ingenuity is truly amazing! Yet, that story is more than just interesting history. It also gives us a sense of perspective. At a time when many boast about modern technology, we are reminded of just how much we owe to the brilliant and fertile minds that preceded us.
