The Librarian Who Measured the Earth is a picture book about an ancient Greek mathematician and geographer. The story starts off with a cute description of Eratosthenes as a baby and soon becomes complex as it describes how he calculated the circumference of the earth. It's a noble effort to attempt to explain something mathematically complicated to picture book readers. I think of it as a seed planting book. Children reading it may not understand everything going on in the book, but it plants the seeds of ideas in their heads that will inform future studies or inspire them to learn more about ancient Greece or some of the mathematical concepts described. Any book that takes math out of the realm of worksheets and turns it into a living subject with a history and personalities is well worth reading.

This picture book relates the story of Eratosthenes, a librarian, historian and mathematician. Around 200 B.C. As a child, he loved to ask questions and explore science and math. As an adult, Eratosthenes became a tutor to the son of King Ptolemy II of Egypt, where he succeeded in estimating the circumference of the Earth. The author attempts to explain his mathematical concepts in easy-to-understand language however, I suspect that it would still be too complex for young children.

This biography tells the life story of the Greek scholar, Eratosthenes, the father of modern day geography, who lived more than two thousand years ago. Although there is not much known about the personal life of Eratosthenes, Lasky presents Eratosthenes professional work and accomplishments. The most prominent of these being the measurement of the circumference of the world and the writing the first book of geography. Kathryn Lasky makes curiosity and asking questions a positive quality in young Eratosthenes. Indeed, she connects his curiosity to his many discoveries. The illustrations by Kevin Hawkes are brightly colored and add a light feeling and humor to this subject. Many of the illustrations show children or animals in a humorous or lighthearted way. Eratosthenes is portrayed in an objective way. His work is shown with his successes and failures. However, the author writes in the author¿s note that she needed to make up information, especially about parts of his life that are unknown, using an educated guess. I recommend this book to older, more advanced children and adults interested in math and science and for people, like me, who are interested in learning something new.

Great book for children in the 8-10 age range. Not so great for younger children. This book tells the story of the first person to write a complete geography book and how he figured out the measurements without the modern tools we have today. Great book that points out the good things about asking questions.

The story of Eratosthenes, the librarian of Alexandria who accurately measured the circumferrence of the earth in the third century BC. This is a very short story which can be read in one sitting.

Lasky tries to oversimplify the mathematics and manages to munge the explanation. My 9 year old can see that the earth would have to curl around the sun in order for the sun's rays to shine straight down every hole. It might take another page or two, but really, if you're going to explain the mathematics, do it right or not at all.
