Scientific American: Information from Answers.com Mobile

Scientific American

U.S. monthly magazine interpreting scientific developments to lay readers. It was founded in 1845 as a newspaper describing new inventions. By 1853 its circulation had reached 30,000 and it was reporting on various sciences, such as astronomy and medicine, apart from inventions. In 1921 it became a monthly. From its founding it used woodcut illustrations, and it was one of the first papers to use halftone illustrations. Its articles — solidly based on scholarly research, well written, carefully edited, and accompanied by definitions of scientific terms and by illustrations — have made it the most highly regarded magazine of its genre.
