" A proper scientific reference is usually a published article in a reliable scientific magazine. These days the magazines are slick glossy paper with pictures on the front and lots of advertisements, a lot of editorial material by people who are professional journalists, and a few pictures of girls selling you things you might want to buy for your lab.
