Pages : 0

Book Description
In the Twentieth Century Albert Einstein and others made some astonishing discoveries. They showed us how our universe could start with a Big Bang which seems to allow something to appear from nothing, that Space can be curved and why there may have been a time when there was no Time. If you have always been absolutely baffled by anything related to Space-time then this book is for you. My writing mission is to engage with a new audience that has no previous knowledge of science, and I go to great lengths (without any equations) to make sure that everybody can fully understand my explanations.Unfortunately, Space-time has a reputation for being difficult. The first thing I will do is show that this claim is false. In this book nothing is too hard to understand and I will also encourage you to participate in the scientific process. Don't worry, you are not going to need your own laboratory; everything can be done in the comfort of your own home with Thought Experiments.

The Revolt of The Public and the Crisis of Authority in the New Millennium

The Revolt of The Public and the Crisis of Authority in the New Millennium PDF Author: Martin Gurri
Publisher: Stripe Press
ISBN: 1953953344
Category : Political Science
Languages : en
Pages : 465

Book Description
How insurgencies—enabled by digital devices and a vast information sphere—have mobilized millions of ordinary people around the world. In the words of economist and scholar Arnold Kling, Martin Gurri saw it coming. Technology has categorically reversed the information balance of power between the public and the elites who manage the great hierarchical institutions of the industrial age: government, political parties, the media. The Revolt of the Public tells the story of how insurgencies, enabled by digital devices and a vast information sphere, have mobilized millions of ordinary people around the world. Originally published in 2014, The Revolt of the Public is now available in an updated edition, which includes an extensive analysis of Donald Trump’s improbable rise to the presidency and the electoral triumphs of Brexit. The book concludes with a speculative look forward, pondering whether the current elite class can bring about a reformation of the democratic process and whether new organizing principles, adapted to a digital world, can arise out of the present political turbulence.

The Secret of Our Success

The Secret of Our Success PDF Author: Joseph Henrich
Publisher: Princeton University Press
ISBN: 0691178437
Category : Psychology
Languages : en
Pages : 464

Book Description
How our collective intelligence has helped us to evolve and prosper Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals? This book shows that the secret of our success lies not in our innate intelligence, but in our collective brains—on the ability of human groups to socially interconnect and learn from one another over generations. Drawing insights from lost European explorers, clever chimpanzees, mobile hunter-gatherers, neuroscientific findings, ancient bones, and the human genome, Joseph Henrich demonstrates how our collective brains have propelled our species' genetic evolution and shaped our biology. Our early capacities for learning from others produced many cultural innovations, such as fire, cooking, water containers, plant knowledge, and projectile weapons, which in turn drove the expansion of our brains and altered our physiology, anatomy, and psychology in crucial ways. Later on, some collective brains generated and recombined powerful concepts, such as the lever, wheel, screw, and writing, while also creating the institutions that continue to alter our motivations and perceptions. Henrich shows how our genetics and biology are inextricably interwoven with cultural evolution, and how culture-gene interactions launched our species on an extraordinary evolutionary trajectory. Tracking clues from our ancient past to the present, The Secret of Our Success explores how the evolution of both our cultural and social natures produce a collective intelligence that explains both our species' immense success and the origins of human uniqueness.

The Cult of Smart

The Cult of Smart PDF Author: Fredrik deBoer
Publisher: All Points Books
ISBN: 1250200385
Category : Education
Languages : en
Pages : 149

Book Description
Named one of Vulture’s Top 10 Best Books of 2020! Leftist firebrand Fredrik deBoer exposes the lie at the heart of our educational system and demands top-to-bottom reform. Everyone agrees that education is the key to creating a more just and equal world, and that our schools are broken and failing. Proposed reforms variously target incompetent teachers, corrupt union practices, or outdated curricula, but no one acknowledges a scientifically-proven fact that we all understand intuitively: Academic potential varies between individuals, and cannot be dramatically improved. In The Cult of Smart, educator and outspoken leftist Fredrik deBoer exposes this omission as the central flaw of our entire society, which has created and perpetuated an unjust class structure based on intellectual ability. Since cognitive talent varies from person to person, our education system can never create equal opportunity for all. Instead, it teaches our children that hierarchy and competition are natural, and that human value should be based on intelligence. These ideas are counter to everything that the left believes, but until they acknowledge the existence of individual cognitive differences, progressives remain complicit in keeping the status quo in place. This passionate, voice-driven manifesto demands that we embrace a new goal for education: equality of outcomes. We must create a world that has a place for everyone, not just the academically talented. But we’ll never achieve this dream until the Cult of Smart is destroyed.

Languages : en
Pages : 210

Book Description
"Like A Wrinkle in Time (Miranda's favorite book), When You Reach Me far surpasses the usual whodunit or sci-fi adventure to become an incandescent exploration of 'life, death, and the beauty of it all.'" —The Washington Post This Newbery Medal winner that has been called "smart and mesmerizing," (The New York Times) and "superb" (The Wall Street Journal) will appeal to readers of all types, especially those who are looking for a thought-provoking mystery with a mind-blowing twist. Shortly after a fall-out with her best friend, sixth grader Miranda starts receiving mysterious notes, and she doesn’t know what to do. The notes tell her that she must write a letter—a true story, and that she can’t share her mission with anyone. It would be easy to ignore the strange messages, except that whoever is leaving them has an uncanny ability to predict the future. If that is the case, then Miranda has a big problem—because the notes tell her that someone is going to die, and she might be too late to stop it. Winner of the Boston Globe–Horn Book Award for Fiction A New York Times Bestseller and Notable Book Five Starred Reviews A Junior Library Guild Selection "Absorbing." —People "Readers ... are likely to find themselves chewing over the details of this superb and intricate tale long afterward." —The Wall Street Journal "Lovely and almost impossibly clever." —The Philadelphia Inquirer "It's easy to imagine readers studying Miranda's story as many times as she's read L'Engle's, and spending hours pondering the provocative questions it raises." —Publishers Weekly, Starred review
