This classic series will excite students' imaginations while enriching skills in logical thinking. Logic Countdown problems are easy to incorporate into lesson plans and are formatted to enhance the fullest spectrum of curriculum areas while sharpening thinking skills. Challenging and instructional, these thought-provoking books present sequential exercises in logical reasoning that include relationships, analogies, syllogisms, sequences, deductive reasoning, inference, truth-values, and logical notation. Simple grids coupled with intriguing problems evoke enthusiasm and inspire students to higher and higher levels of thinking. Each book builds on concepts presented previously in the series to offer a comprehensive logic adventure for young thinkers. The skills students build by using this book are applicable to several areas of the curriculum. Academic skills used for reading, math, writing, and science all depend on the ability to perceive and define relationships and to form inferences. But, beyond the academic world, students will find logical thinking an integral part of everyday life. This is the first in a three-book series designed to sharpen children's logical thinking skills. Once students master the skills presented in this book, they will be ready for new challenges in Logic Liftoff and Orbiting with Logic. Grades 3-4

When a Serbian-backed assassin gunned down Archduke Franz Ferdinand in late June 1914, the world seemed unmoved. Even Ferdinand's own uncle, Franz Josef I, was notably ambivalent about the death of the Hapsburg heir, saying simply, "It is God's will." Certainly, there was nothing to suggest that the episode would lead to conflict -- much less a world war of such massive and horrific proportions that it would fundamentally reshape the course of human events. As acclaimed historian Sean McMeekin reveals in July 1914, World War I might have been avoided entirely had it not been for a small group of statesmen who, in the month after the assassination, plotted to use Ferdinand's murder as the trigger for a long-awaited showdown in Europe. The primary culprits, moreover, have long escaped blame. While most accounts of the war's outbreak place the bulk of responsibility on German and Austro-Hungarian militarism, McMeekin draws on surprising new evidence from archives across Europe to show that the worst offenders were actually to be found in Russia and France, whose belligerence and duplicity ensured that war was inevitable. Whether they plotted for war or rode the whirlwind nearly blind, each of the men involved -- from Austrian Foreign Minister Leopold von Berchtold and German Chancellor Bethmann Hollweg to Russian Foreign Minister Sergei Sazonov and French president Raymond Poincaré- sought to capitalize on the fallout from Ferdinand's murder, unwittingly leading Europe toward the greatest cataclysm it had ever seen. A revolutionary account of the genesis of World War I, July 1914 tells the gripping story of Europe's countdown to war from the bloody opening act on June 28th to Britain's final plunge on August 4th, showing how a single month -- and a handful of men -- changed the course of the twentieth century.

It's never too early to start building thinking skills—skills that will spill over into other areas of the curriculum and into real life. Primarily Logic consists of a series of units designed to introduce logical thinking to young students. It is an excellent, easy-to-use starting point for teaching well-established forms of logical thinking. Each skill is introduced with examples, and then worksheets give students an opportunity to practice the skill. Group lessons and worksheets provide practice in: finding relationships, analogies, thinking logically using “all” and “none” statements, syllogisms, and deductive reasoning using logic puzzles. Logical thinking is both enjoyable and challenging for students as they build a sound foundation for further instruction in critical thinking. Suggestions for related activities are included in the Instructions for Teachers section. For easier logic activities for younger students, try Lollipop Logic. Grades 2-4

A top cybersecurity journalist tells the story behind the virus that sabotaged Iran’s nuclear efforts and shows how its existence has ushered in a new age of warfare—one in which a digital attack can have the same destructive capability as a megaton bomb. “Immensely enjoyable . . . Zetter turns a complicated and technical cyber story into an engrossing whodunit.”—The Washington Post The virus now known as Stuxnet was unlike any other piece of malware built before: Rather than simply hijacking targeted computers or stealing information from them, it proved that a piece of code could escape the digital realm and wreak actual, physical destruction—in this case, on an Iranian nuclear facility. In these pages, journalist Kim Zetter tells the whole story behind the world’s first cyberweapon, covering its genesis in the corridors of the White House and its effects in Iran—and telling the spectacular, unlikely tale of the security geeks who managed to unravel a top secret sabotage campaign years in the making. But Countdown to Zero Day also ranges beyond Stuxnet itself, exploring the history of cyberwarfare and its future, showing us what might happen should our infrastructure be targeted by a Stuxnet-style attack, and ultimately, providing a portrait of a world at the edge of a new kind of war.

Science undergraduates have come to accept the use of computers as commonplace. The daily use of portable sophisticated electronic calculators (some of them rivaling general-purpose minicomputers in their capa bi li ti es) has hastened this development. Over the past several years, computer assisted experimentation has assumed an important role in the experimental laboratory. Mini- and microcomputer systems have become an important part of the physical scientist's array of analytical instruments. Prompted by our beliefthat this was an inevitable development, we began several years aga to develop the curricular materials presented in this manual. At the outset, several objectives seemed important to uso First, insofar as possible, the experiments included should be thoroughly tested and error free. Second, they should be compatible with a variety of laboratory computer, data-acquisition, and control systems. Third, little or no previous background in either electronics or programming should be necessary. (Of course, such background would be advantageous. ) To satisfy these objectives, we decided to adopt a widespread high-level computer language, BASIC, suitably modified for the purpose. Furthermore, we have purposely avoided specifying any particular system or equipment. Rather, the functional characteristics of both hardware and software required are stipulated. The experiments have been developed using Varian 620 and Hewlett-Packard 2100 series computers, but we believe they are readily transferable to other commonly available computer systems with a minimum of difficulty.
