Subsequently , an amalgamation of chemical technologies and philosophical speculations were spread from Egypt , China , and the eastern Mediterranean by alchemists , who endeavored to transform `` base metals '' such as lead into `` noble metals '' like gold , and to create elixirs to cure disease and extend life . From alchemy came the historical progressions that led to modern chemistry : the isolation of drugs from natural sources , metallurgy , and the dye industry . Today , chemistry continues to deepen our understanding and improve our ability to harness and control the behavior of matter . This effort has been so successful that many people do not realize either the central position of chemistry among the sciences or the importance and universality of chemistry in daily life . Chemistry is sometimes referred to as `` the central science '' due to its interconnectedness with a vast array of other STEM disciplines -LRB- STEM stands for areas of study in the science , technology , engineering , and math fields -RRB- .
