The art of asking matter exactly what it's made of, and making it answer.
means The branch of chemistry devoted to identifying what substances are present in a sample and measuring how much of each there is.
from From Greek 'analytikos,' rooted in 'analyein' meaning 'to unloose' or 'to break up' — the same root that gives us 'analysis.' The idea: you take something whole and dissolve it into its separate pieces to see what it's made of. 'Chemistry' itself traces back through medieval Latin and Arabic 'al-kimia' to older roots tangled up with 'khemia,' possibly linked to the black soil of Egypt or to Greek 'khymeia,' the art of alloying metals. So the name is literally 'the untying of substances' — a discipline named for the act of taking things apart to learn their secrets.
