Etymology

Origin of scientific

1580–90; < Medieval Latin scientificus, equivalent to scient- ( see science) + -i - -i- + -ficus -fic

Explanation

Things that are scientific are based on the principles and methods of science. Scientific evidence is the result of study and experimentation, not opinions and guesses. If you want to prove something, finding scientific support is your best bet. The scientific method is the surest way to study and learn about things because it involves experiments, research, and careful analysis of the facts. Scientific evidence is more than an opinion or a wish — it's been studied and supported by some of our best minds. Anyone can have an opinion, but it doesn't mean much without scientific studies to back it up.
