For many the field of chemistry is a terra incognita, an unknown world. This is odd if one considers that humans are virtually chemistry factories, ingesting, processing and producing chemicals throughout our lives. We routinely use a wide variety of chemicals without ever thinking of them in those terms, from detergents to medications. Besides, with all kinds of wonderful electronic gadgets, who needs to know anything about chemistry or chemicals anyway? On top of that, we are constantly told that chemicals are dangerous to our health. Everything else, including meteorites are too.
