How does our fascination with technology intersect with the religious imagination? In TechGnosis-a cult classic now updated and reissued with a new afterword-Erik Davis argues that while the realms of the digital and the spiritual may seem worlds apart, esoteric and religious impulses have in fact always permeated (and sometimes inspired) technological communication. Davis uncovers startling connections between such seemingly disparate topics as electricity and alchemy; online roleplaying games and religious and occult practices; virtual reality and gnostic mythology; programming languages and Kabbalah. The final chapters address the apocalyptic dreams that haunt technology, providing vital historical context as well as new ways to think about a future defined by the mutant intermingling of mind and machine, nightmare and fantasy.

'One of the greatest, most radical public thinkers of our time. When the sun sets on the American empire, as it will, as it must, Noam Chomsky's work will survive' Arundhati RoyFrom one of the world's most prominent thinkers comes an urgent warning of the threat that US power poses to humanity's futureThe land of the free. The home of the brave. But what has America achieved in the aim of 'spreading democracy' - except wreak havoc across the globe and establish a reckless foreign policy that serves the interest of few and has endangered all too many?In this timely book, Noam Chomsky writing with Nathan J. Robinson, vividly traces America's pursuit of global domination, offering an incisive critique of the self-serving myths that dominant elites in the United States continue to push.Offering penetrating accounts of Washington's role in the Israeli-Palestinian conflict and the wars in Iraq and Afghanistan, they examine how interventions such as these have been justified with noble stories about humanitarian missions and benevolent intentions but are now driving us closer to wars with Russia and China.At once thorough and devastating, urgent and provocative, The Myth of American Idealism offers a highly readable entry to the conclusions Noam Chomsky has come to after a lifetime of thought and activism.'The west's most prominent critic of US imperialism . . . the closest thing in the English-speaking world to an intellectual superstar' Guardian

This book is aimed at everyone preparing for the ISTQB® Certified Tester ¿ Foundation Level exam based on the Foundation Level syllabus (version 4.0) published in 2023. It provides candidates with reliable knowledge based on this document and thus distinguishes itself from all the information about ISTQB® syllabi and exams on the Internet, which is often of rather poor quality and may even contain serious errors. The book expands and details many issues that are described in the new 2023 version of the syllabus in a perfunctory or general way only. According to the ISTQB® guidelines for syllabus-based training, an exercise must be provided for each learning objective at the K3 level, and a practical example must be provided for each objective at the K2 or K3 level. In order to satisfy these requirements, the authors prepared numerous exercises and examples for all learning objectives at these levels. In addition, for each learning objective, one or more sample exam questions are presented which are similar to those that the candidate will see in the exam. This makes the book an excellent aid for studying and preparing for the exam and verifying acquired knowledge.

NEW YORK TIMES BESTSELLER • A progressive takedown of the uber-capitalist status quo that has enriched millionaires and billionaires at the expense of the working class, and a blueprint for what transformational change would actually look like—with a new afterword“A clarion call against the American oligarchs . . . powerful.”—The GuardianIt’s OK to be angry about capitalism. Reflecting on our turbulent times, Senator Bernie Sanders takes on the billionaire class and speaks blunt truths about our country’s failure to address the destructive nature of a system that is fueled by uncontrolled greed and rigidly committed to prioritizing corporate profits over the needs of ordinary Americans.Sanders argues that unfettered capitalism is to blame for an unprecedented level of income and wealth inequality, is undermining our democracy, and is destroying our planet. How can we accept an economic order that allows three billionaires to control more wealth than the bottom half of our society? How can we accept a political system that allows the super rich to buy politicians and swing elections? How can we accept an energy system that rewards the fossil fuel corporations causing the climate crisis? Sanders believes that, in the face of these overwhelming challenges, the American people must ask tough questions about the systems that have failed us and demand fundamental economic and political change. This is where the path forward begins.It’s OK to Be Angry About Capitalism presents a vision that extends beyond the promises of past campaigns to reveal what would be possible if the political revolution took place, if we would finally recognize that economic rights are human rights, and if we would work to create a society that provides a decent standard of living for all. This isn’t some utopian fantasy; this is democracy as we should know it.

NEW YORK TIMES BESTSELLER • Stephen Hawking’s closest collaborator offers the intellectual superstar’s final thoughts on the cosmos—a dramatic revision of the theory he put forward in A Brief History of Time.“This superbly written book offers insight into an extraordinary individual, the creative process, and the scope and limits of our current understanding of the cosmos.”—Lord Martin ReesPerhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. In order to solve this mystery, Hawking studied the big bang origin of the universe, but his early work ran into a crisis when the math predicted many big bangs producing a multiverse—countless different universes, most of which would be far too bizarre to ​harbor life. Holed up in the theoretical physics department at Cambridge, Stephen Hawking and his friend and collaborator Thomas Hertog worked on this problem for twenty years, developing a new theory of the cosmos that could account for the emergence of life. Peering into the extreme quantum physics of cosmic holograms and venturing far back in time to our deepest roots, they were startled to find a deeper level of evolution in which the physical laws themselves transform and simplify until particles, forces, and even time itself fades away. This discovery led them to a revolutionary idea: The laws of physics are not set in stone but are born and co-evolve as the universe they govern takes shape. As Hawking’s final days drew near, the two collaborators published their theory, which proposed a radical new Darwinian perspective on the origins of our universe. On the Origin of Time offers a striking new vision of the universe’s birth that will profoundly transform the way we think about our place in the order of the cosmos and may ultimately prove to be Hawking’s greatest legacy.
