Book Synopsis Spider Webs by : William Eberhard

Download or read book Spider Webs written by William Eberhard. This book was released on 2020-12-22. Available in PDF, EPUB and Kindle. Book excerpt: In this lavishly illustrated, first-ever book on how spider webs are built, function, and evolved, William Eberhard provides a comprehensive overview of spider functional morphology and behavior related to web building, and of the surprising physical agility and mental abilities of orb weavers. For instance, one spider spins more than three precisely spaced, morphologically complex spiral attachments per second for up to fifteen minutes at a time. Spiders even adjust the mechanical properties of their famously strong silken lines to different parts of their webs and different environments, and make dramatic modifications in orb designs to adapt to available spaces. This extensive adaptive flexibility, involving decisions influenced by up to sixteen different cues, is unexpected in such small, supposedly simple animals. As Eberhard reveals, the extraordinary diversity of webs includes ingenious solutions to gain access to prey in esoteric habitats, from blazing hot and shifting sand dunes (to capture ants) to the surfaces of tropical lakes (to capture water striders). Some webs are nets that are cast onto prey, while others form baskets into which the spider flicks prey. Some aerial webs are tramways used by spiders searching for chemical cues from their prey below, while others feature landing sites for flying insects and spiders where the spider then stalks its prey. In some webs, long trip lines are delicately sustained just above the ground by tiny rigid silk poles. Stemming from the author’s more than five decades observing spider webs, this book will be the definitive reference for years to come.

Book Synopsis Spider Web by : Nick Fischer

Download or read book Spider Web written by Nick Fischer. This book was released on 2016-05-15. Available in PDF, EPUB and Kindle. Book excerpt: The McCarthy-era witch hunts marked the culmination of an anticommunist crusade launched after the First World War. With Bolshevism triumphant in Russia and public discontent shaking the United States, conservatives at every level of government and business created a network dedicated to sweeping away the "spider web" of radicalism they saw threatening the nation. In this groundbreaking study, Nick Fischer shines a light on right-wing activities during the interwar period. Conservatives, eager to dispel communism's appeal to the working class, railed against a supposed Soviet-directed conspiracy composed of socialists, trade unions, peace and civil liberties groups, feminists, liberals, aliens, and Jews. Their rhetoric and power made for devastating weapons in their systematic war for control of the country against progressive causes. But, as Fischer shows, the term spider web far more accurately described the anticommunist movement than it did the makeup and operations of international communism. Fischer details how anticommunist myths and propaganda influenced mainstream politics in America, and how its ongoing efforts paved the way for the McCarthyite Fifties--and augured the conservative backlash that would one day transform American politics.

Book excerpt: For ten years, the White House, assisted by allies in London and Rome, brushed aside the law in a relentless quest to support Saddam Hussein. What were the forces that shaped this persisting embrace of a dictator whom George Bush would eventually compare to Adolf Hitler? How did Washington and its NATO allies nurture a frequently illicit rapport with Saddam, and what was the real story of why it became necessary to mount Operation Desert Storm? How did the governments led by George Bush and Margaret Thatcher seek to cover up their past dealings with the Iraqi leader after Desert Storm finally drove him from Kuwait in 1991?

Book Synopsis The Best Class You Never Taught by : Alexis Wiggins

Download or read book The Best Class You Never Taught written by Alexis Wiggins. This book was released on 2017-09-27. Available in PDF, EPUB and Kindle. Book excerpt: The best classes have a life of their own, powered by student-led conversations that explore texts, ideas, and essential questions. In these classes, the teacher’s role shifts from star player to observer and coach as the students ▪ Think critically, ▪ Work collaboratively, ▪ Participate fully, ▪ Behave ethically, ▪ Ask and answer high-level questions, ▪ Support their ideas with evidence, and ▪ Evaluate and assess their own work. The Spider Web Discussion is a simple technique that puts this kind of class within every teacher’s reach. The name comes from the weblike diagram the observer makes to record interactions as students actively participate in the discussion, lead and support one another’s learning, and build community. It’s proven to work across all subject areas and with all ages, and you only need a little know-how, a rubric, and paper and pencil to get started. As students practice Spider Web Discussion, they become stronger communicators, more empathetic teammates, better problem solvers, and more independent learners—college and career ready skills that serve them well in the classroom and beyond. Educator Alexis Wiggins provides a step-by-step guide for the implementation of Spider Web Discussion, covering everything from introducing the technique to creating rubrics for discussion self-assessment to the nuts-and-bolts of charting the conversations and using the data collected for formative assessment. She also shares troubleshooting tips, ideas for assessment and group grading, and the experiences of real teachers and students who use the technique to develop and share content knowledge in a way that’s both revolutionary and truly inspiring.
