Etymology
Origin of chemist
First recorded in 1555–65; from Greek chēm(ía) (also chēmeía, chymeía ) “art of alloying metals; alchemy” + -ist; replacing chymist, from Medieval Latin alchimista; see alchemist ( def. )
Explanation
A scientist who studies the elements that make up all matter is a chemist. If you enjoy doing experiments that involve mixing substances in test tubes, you'd probably love being a chemist. Chemists practice the science of chemistry, which examines the properties that make up everything in the universe. These working scientists examine the tiniest particles of substances, the atoms and molecules that form the earth, the oceans, and even you, yourself. Chemists also study how elements interact with each other and form new substances; we have chemists to thank for inventing penicillin, plastic, and artificial sweeteners, among many other things.
