The author of Mesmerized shares another comical true tale of a Founding Father using science to defeat ignorance and stop the spread of false information. Thomas Jefferson was wild about numbers. He was constantly counting, measuring, and observing things that caught his interest. He loved sharing his discoveries and reading the discoveries of others. But when a famous Frenchman published a book about America, Jefferson was appalled: all the information in the book was wrong. The author insisted that America was a wretched, dismal place, where birds could not sing, dogs could not bark, and everything and everyone was puny and weak. Thomas Jefferson resolved to set the record straight — with numbers — and prove to the world that the new nation was worthy of investment. But how do you show that a country is plentiful in an age when photography hasn’t been invented yet? Mara Rockliff, master of children’s nonfiction, details another little-known moment in math and natural history, illustrated with humor by prolific artist S. D. Schindler and accompanied by extensive back matter and an informative author’s note. Gr 2-5-Thomas Jefferson had an affinity for numbers. He measured anything that sparked his curiosity-the miles in an hour's walk, the weight of a cow, and temperatures of the land and sea. When a French natural history expert named Buffon criticized the natural resources of America and called the country "a terrible, miserable, cold, damp place where nothing good could grow," Jefferson was determined to prove him wrong. He measured different animals, including bears, bison, beavers, and a moose, to show Buffon and the world that America was not an inhospitable land. Rockliff depicts a lesser-known side of Jefferson-the mathematician. The text reads well, and older children could handle the language on their own, even if some of the more tongue-in-cheek comments go over their heads. Schindler's illustrations evoke a distinct sense of place and time. Some readers, educators, and caretakers may find the artwork of the moose carcass, stink lines and all, a little off-putting. The back matter includes two sections entitled "A Mania for Math" and "Jefferson's Numbers," which provide a deeper dive into the statesman's fascination with math and the answers he sought. Lists of primary and secondary sources are also featured.

In Rockliff’s rollicking tale, Jefferson jots down numbers everywhere he goes...Children obsessed with the early republic and with science may find this obscure tale entertaining. —Kirkus Reviews Rockliff’s well-paced, wryly funny narration is enjoyable as well as informative (if Buffon “believed in chirpless chickadees and puny pigs, then so would everybody else”). Schindler’s familiar gravely humorous delicacy, in line and watercolor that sometimes echoes wood engraving with its hatching, is perfectly suited to the personable recounting of a polite historical feud. This would be a boon to early math classes or discussions about the importance of data, but it also serves as offbeat entertainment. —Bulletin of the Center for Children's Books Schindler’s period illustrations, washed in faded color, depict the supercilious bewigged Buffon and an alarmingly limp moose carcass. Supplemental materials answer the outlandish questions Rockliff’s Jefferson poses and shed light on his “mania for math.” —Publishers Weekly Rockliff depicts a lesser-known side of Jefferson—the mathematician.
