Alcune idee, oggetti ed eventi sono così lontani o così grandi che è difficile immaginarli. Lo spazio, la storia, le invenzioni, la vita sulla Terra... Cosa succederebbe se li rimpicciolissimo? L'autore di "Se...", David Smith, usa la riduzione in scala per rendere comprensibili le grandi idee e i grandi numeri che ci circondano e mostrarci il mondo in maniera del tutto nuova e sorprendente. Se il Sole avesse le dimensioni di un pompelmo, la Terra sarebbe un granello di sale e Giove non sarebbe più grande di un sassolino. Se tutta l'acqua della Terra fosse rappresentata da 100 bicchieri, solo 3 conterrebbero tutta l'acqua dolce del nostro pianeta. Se i 3,5 miliardi di anni di vita sulla Terra fossero condensati in una sola ora, i dinosauri non comparirebbero prima di 56 minuti e scomparirebbero 3 minuti dopo. Età di lettura: da 7 anni.

"Some things are so huge or so old that it's hard to wrap your mind around them. But what if we took these big, hard-to-imagine objects and events and compared them to things we can see, feel and touch? Instantly, we'd see our world in a whole new way." So begins this endlessly intriguing guide to better understanding all those really big ideas and numbers children come across on a regular basis. Author David J. Smith has found clever devices to scale down everything from time lines (the history of Earth compressed into one year), to quantities (all the wealth in the world divided into one hundred coins), to size differences (the planets shown as different types of balls). Accompanying each description is a kid-friendly drawing by illustrator Steve Adams that visually reinforces the concept. By simply reducing everything to human scale, Smith has made the incomprehensible easier to grasp, and therefore more meaningful. The children who just love these kinds of fact-filled, knock-your-socks-off books will want to read this one from cover to cover. It will find the most use, however, as an excellent classroom reference that can be reached for again and again when studying scale and measurement in math, and also for any number of applications in social studies, science and language arts. For those who want to delve a little deeper, Smith has included six suggestions for classroom projects. There is also a full page of resource information at the back of the book.

From the late nineteenth century until World War I, a group of Columbia University students gathered under the mentorship of the renowned historian William Archibald Dunning (1857--1922). Known as the Dunning School, these students wrote the first generation of state studies on the Reconstruction -- volumes that generally sympathized with white southerners, interpreted radical Reconstruction as a mean-spirited usurpation of federal power, and cast the Republican Party as a coalition of carpetbaggers, freedmen, scalawags, and former Unionists.

Edited by the award-winning historian John David Smith and J. Vincent Lowery, The Dunning School focuses on this controversial group of historians and its scholarly output. Despite their methodological limitations and racial bias, the Dunning historians' writings prefigured the sources and questions that later historians of the Reconstruction would utilize and address. Many of their pioneering dissertations remain important to ongoing debates on the broad meaning of the Civil War and Reconstruction and the evolution of American historical scholarship.

This groundbreaking collection of original essays offers a fair and critical assessment of the Dunning School that focuses on the group's purpose, the strengths and weaknesses of its constituents, and its legacy. Squaring the past with the present, this important book also explores the evolution of historical interpretations over time and illuminates the ways in which contemporary political, racial, and social questions shape historical analyses.
