ما هو الفرق بين الكيمياء والخيمياء ؟
The protoscience of chemistry, alchemy, was unsuccessful in explaining the nature of matter and its transformations. However, by performing experiments and recording the results, alchemists set the stage for modern chemistry. The distinction began to emerge 
when a clear differentiation was made between chemistry and alchemy by Robert Boyle in his work "The Sceptical Chymist" (1661). While both alchemy and chemistry are concerned with matter and its transformations, chemists are seen as applying scientific method to their work.
