The Discovery of Longitude

(4) 4-6 Illustrated by Wes Lowe. Galat clearly explains the basics of how early navigation worked, the limitations of sailing with just latitude as a marker, and how one man solved the longitude puzzle. Lowe's paintings help set time and place, but human figures are stiff. The complex concepts are best suited for older readers beyond the traditional picture-book age with understanding of math, science, and geography. Timeline.
