Jabir ibn Hayyan 7 (An Islamic Scientist)

 Several instruments which he designed a thousand years ago are still being used in modern chemical laboratory such as retort, pipette and test tube. Jabir bin Hayyan defined chemical combination as union of the elements together in small particles too small for the naked eyes to see without loss of their characteristics. This idea was not very far from idea of John Dalton (d 1844) about the atoms, the English chemist and physicist who discovered it ten centuries later. Jabir’s works seem to have been deliberately written in highly esoteric code so that only those who had been initiated into his alchemical school could understand them.Jabir ibn Hayyan 2 (An Islamic Scientist)
