註釋

Scientific American (informally abbreviated SciAm or sometimes SA) is an American popular science magazine. Many famous scientists, including Albert Einstein, have contributed articles to it. It is the oldest continuously published monthly magazine in the United States (though it only became monthly in 1921).
