Presents a collection of incorrect yet humorous test answers from real students, from an elementary student claiming that "two halves make a whale" to a high schooler who credits Galileo with inventing the solar system.
Designers of high-speed integrated circuits face a bewildering array of choices and too often spend frustrating days tweaking gates to meet speed targets. Logical Effort: Designing Fast CMOS Circuits makes high speed design easier and more methodical, providing a simple and broadly applicable method for estimating the delay resulting from factors such as topology, capacitance, and gate sizes. The brainchild of circuit and computer graphics pioneers Ivan Sutherland and Bob Sproull, "logical effort" will change the way you approach design challenges. This book begins by equipping you with a sound understanding of the method's essential procedures and concepts-so you can start using it immediately. Later chapters explore the theory and finer points of the method and detail its specialized applications. Features Explains the method and how to apply it in two practically focused chapters. Improves circuit design intuition by teaching simple ways to discern the consequences of topology and gate size decisions. Offers easy ways to choose the fastest circuit from among an array of potential circuit designs. Reduces the time spent on tweaking and simulations-so you can rapidly settle on a good design. Offers in-depth coverage of specialized areas of application for logical effort: skewed or unbalanced gates, other circuit families (including pseudo-NMOS and domino), wide structures such as decoders, and irregularly forking circuits. Presents a complete derivation of the method-so you see how and why it works.
F stands for "funny" in this perfect gift for students or anyone who has ever had to struggle through a test and needs a good laugh. Celebrating the creative side of failure in a way we can all relate to, F in Exams gathers the most hilarious and inventive test answers provided by students who, faced with a question they have no hope of getting right, decide to have a little fun instead. Whether in science (Q: What is the highest frequency noise that a human can register? A: Mariah Carey), the humanities (Q: What did Mahatma Gandhi and Genghis Khan have in common? A: Unusual names), math, or other subjects, these 250 entries prove that while everyone enjoys the spectacle of failure, it's even sweeter to see a FAIL turn into a WIN.
This timely volume reveals in great detail how educators closed the “performance gap” for low-income students by linking expectations and results. Drawing heavily on the words and experiences of students, teachers, and parents, this book describes how students who traditionally had not succeeded academically in school began to do so. Effort and Excellence in Urban Classrooms demonstrates just how this was done by including: In-depth descriptions of classrooms and schools where students began succeeding when educators assumed the responsibility for their successData-based discussion of teachers’ views on parental involvement in schools and parents’ views of teachers’ and schools’ actions on behalf of studentsIdentification of the kinds of support that schools and districts must provide if educators are to be successfulAn unrelenting emphasis on how educators enabled students to be motivated and to produce high-quality work “At last, a book that helps us see and feel what a ‘no excuses’ approach to teaching is like in urban classrooms! This close look at teachers and students in high-poverty settings gives new meaning to ‘all children can learn.’ A must read for those who are serious about closing the achievement gap.” —Michael S. Knapp, Center for the Study of Teaching & Policy, University of Washington
One of the world's most esteemed and influential psychologists, Roy F. Baumeister, teams with New York Times science writer John Tierney to reveal the secrets of self-control and how to master it. "Deep and provocative analysis of people's battle with temptation and masterful insights into understanding willpower: why we have it, why we don't, and how to build it. A terrific read." —Ravi Dhar, Yale School of Management, Director of Center for Customer Insights Pioneering research psychologist Roy F. Baumeister collaborates with New York Times science writer John Tierney to revolutionize our understanding of the most coveted human virtue: self-control. Drawing on cutting-edge research and the wisdom of real-life experts, Willpower shares lessons on how to focus our strength, resist temptation, and redirect our lives. It shows readers how to be realistic when setting goals, monitor their progress, and how to keep faith when they falter. By blending practical wisdom with the best of recent research science, Willpower makes it clear that whatever we seek—from happiness to good health to financial security—we won’t reach our goals without first learning to harness self-control.

Through their contemporary diaries and letters, many previously unpublished, we follow the wartime experiences of these northern Indiana volunteers. Their most overpowering encounter was the ferocious battle of Chickamauga. In those woodlands, the 87th Indiana established its bravery forever by standing steadfast with its brigade on three separate occasions, each time saving a significant part of the Union army.
The definitive history of World War II from the African American perspective, by award-winning historian and civil rights expert Winner of the 2023 Anisfield-Wolf Book Award in Nonfiction A New York Times Notable Book of 2022 A 2022 Book of the Year from TIME, Publishers Weekly, Booklist, and more More than one million Black soldiers served in World War II. Black troops were at Normandy, Iwo Jima, and the Battle of the Bulge, serving in segregated units while waging a dual battle against inequality in the very country for which they were laying down their lives. The stories of these Black veterans have long been ignored, cast aside in favor of the myth of the “Good War” fought by the “Greatest Generation.” And yet without their sacrifices, the United States could not have won the war. Half American is World War II history as you’ve likely never read it before. In these pages are stories of Black military heroes and civil rights icons such as Benjamin O. Davis Jr., the leader of the legendary Tuskegee Airmen, who fought to open the Air Force to Black pilots; Thurgood Marshall, the chief lawyer for the NAACP, who investigated and publicized violence against Black troops and veterans; poet Langston Hughes, who worked as a war correspondent for the Black press; Ella Baker, the civil rights leader who advocated on the home front for Black soldiers, veterans, and their families; and James G. Thompson, the twenty-six-year-old whose letter to a newspaper laying bare the hypocrisy of fighting against fascism abroad when racism still reigned at home set in motion the Double Victory campaign. Their bravery and patriotism in the face of unfathomable racism is both inspiring and galvanizing. An essential and meticulously researched retelling of the war, Half American honors the men and women who dared to fight not just for democracy abroad but for their dreams of a freer and more equal America.
