For all of us who are not chemistry majors, or lacking chemistry-related knowledge, this is a nice little book to brush up your knowledge. Each chapter discusses a major concept, has a timeline showing (major) Chemistry developments, some side-notes and the Periodic Table is also present. This series(50 Ideas) is similar to the "30-Seconds series". Although I think that the 30-Seconds-series have been done a bit better. The "50 Ideas" does not use colour in the same way as the "30-Seconds" and looks therefore a little flat. Anyway, still recommended. ( )
