Alchemy bred Chemistry

I want to tell you a story of chemistry. Centuries ago, people thought "Can change stone into gold?". That's the beginning of alchemy. Then people analyzed many thing (mainly those were solid). Finally, people couldn't change stone into gold and the analysis results are just left. But some find out the common from the data. And they sort the common. then try to describe it scientific. It was the first day of chemistry. Chemistry is the child of alchemy and allows us to make new beneficial things; alumite, drug, dynamite, nylon, polyester, rubber and so on. Don't always look on the bad side of chemistry. Your life has already been with some chemicals, and even your cellphone has plastic cover!!
