Surgical Instruments

Many surgical instruments of modern age are exactly the same in design as those in the 10th century by a Muslim surgeon called al-Zahrawi. His forceps , bone saws ,scalpels,  scissors for eye surgery and more than 200 tools he developed are more or less the same used today.The credit goes to him that he was the one who discovered that catgut used for internal stitches dissolves away naturally (a discovery he made when his monkey ate his lute strings) and medical capsules can be made from it . In the 13th century, a Muslim doctor  Ibn Nafis described the circulation of the blood, 300 years before William Harvey discovered. Muslims doctors also invented anesthetics of opium and alcohol mixes and developed hollow needles to suck cataracts from eyes;  a technique still used today.

Camera

The ancient Greeks thought our eyes emitted rays, like a laser, which enabled us to see. The first person to realize that light enters the eye, rather than leaving it, was the 10th-century Muslim mathematician, astronomer and physicist Ibn al-Haitham. He invented the first camera , he noticed how the light came through a hole in the shutters. The smaller the hole, the better the image He designed and built the first camera  (from the Arabic word for qamara dark or private room). He is also credited with being the first man to shift physics from a philosophical activity to an experimental.

    Ibrahim Jandab

    Ibrahim bin Jandab was an astronomer, astrologer and and an inventor who invented the astrolabe. He was a great thinker and through his knowledge he invented a kind of telescope so he could use it not only to view distant objects but also find the distance. He called it "astrolabe".





    In 776 A.D. Ibrahim invented this instrument-the astrolabe while Galellio (1564-1642 AD), an italian scientist modified the original design and made several changes to it, made the telescope.Many people claim that Galellio was the inverntor of the telescope although it had been invented long time earlier by a muslim scientist Ibrahim bin Jandab.

    Astrolabe was made of two hollow pipes. One remained stationary, while the other one could be moved upwards, downwards, left and right. Both these tubes were placed on a stand. hulu
