"The appealing Eureka! The Biography of an Idea series introduces primary-grade students to the history behind familiar inventions, from an initial concept or prototype to versions familiar to users today. The writing is simple, clear, and often lively. Richly colorful, digital artwork suggests the look of different time periods and cultures, while portraying individuals who developed each invention and showing how its appearance has changed through the years. Well attuned to the intended audience, this series is both engaging and informative." —Booklist

"Glasses are nearly ubiquitous now, but who actually invented them? This book is an illustrated time line of that process and includes diagrams of the eye as well as explanations of why a person might need glasses. The artwork is helpful for understanding some of the more complex concepts and the graphics are clearly labeled. The story demonstrates to readers that the glasses that are worn today are the product of lots of collaboration and fine tuning over the centuries, not the work of a single person, which is an idea not often brought forward in discussions of the inventive process... a good addition to any library serving younger patrons who are interested in science and health sciences and inventions."—School Library Journal

"A concise, inclusive history of the evolution of the bicycle. The multicountry perspective (Germany, England, France, America, Ireland, and China are all mentioned) is a refreshing angle; also welcome is the information on ways bicycles were and are used, their efficiency, and the etymology of bicycle names and terms. This engaging history of the bicycle is sure to pique young riders’ interest while it enriches their knowledge." —Kirkus Reviews (for EUREKA: Bicycle)

"This concise history starts with German Karl Drais's 1817 invention of a wooden two-wheeled 'running machine'...[and] culminat[es] with 'a bicycle for just about everybody'....The lively illustrations keep pace with the accessible and engaging text." —The Horn Book (for EUREKA!: Bicycle)»
