In 1790, America was in enormous debt, having depleted what little money and supplies the country had during its victorious fight for independence. Before the nation's greatest asset, the land west of the Ohio River, could be sold it had to be measured out and mapped. And before that could be done, a uniform set of measurements had to be chosen for the new republic out of the morass of roughly 100,000 different units that were in use in daily life. Measuring America tells the fascinating story of how we ultimately gained the American Customary System—the last traditional system in the world—and how one man's surveying chain indelibly imprinted its dimensions on the land, on cities, and on our culture from coast to coast.

Prior to 1735, South America was terra incognita to many Europeans. But that year, the Paris Academy of Sciences sent a mission to the Spanish American province of Quito (in present-day Ecuador) to study the curvature of the earth at the Equator. Equipped with quadrants and telescopes, the mission’s participants referred to the transfer of scientific knowledge from Europe to the Andes as a “sacred fire” passing mysteriously through European astronomical instruments to observers in South America.By taking an innovative interdisciplinary look at the traces of this expedition, Measuring the New World examines the transatlantic flow of knowledge from West to East. Through ephemeral monuments and geographical maps, this book explores how the social and cultural worlds of South America contributed to the production of European scientific knowledge during the Enlightenment. Neil Safier uses the notebooks of traveling philosophers, as well as specimens from the expedition, to place this particular scientific endeavor in the larger context of early modern print culture and the emerging intellectual category of scientist as author.

How do you judge the quality of a school, a district, a teacher, a student? By the test scores, of course. Yet for all the talk, what educational tests can and can’t tell you, and how scores can be misunderstood and misused, remains a mystery to most. The complexities of testing are routinely ignored, either because they are unrecognized, or because they may be—well, complicated. Inspired by a popular Harvard course for students without an extensive mathematics background, Measuring Up demystifies educational testing—from MCAS to SAT to WAIS, with all the alphabet soup in between. Bringing statistical terms down to earth, Daniel Koretz takes readers through the most fundamental issues that arise in educational testing and shows how they apply to some of the most controversial issues in education today, from high-stakes testing to special education. He walks readers through everyday examples to show what tests do well, what their limits are, how easily tests and scores can be oversold or misunderstood, and how they can be used sensibly to help discover how much kids have learned.
