The weirdly alien notion of a space-time abyss from which nothing escapes-not even light-seemed to confound all logic. This engrossing book tells the story of the fierce black hole debates and the contributions of Einstein and Hawking and other leading thinkers who completely altered our view of the universe. Renowned science writer Marcia Bartusiak shows how the black hole helped revive Einstein's greatest achievement, the general theory of relativity, after decades during which it had been pushed into the shadows. Not until astronomers discovered such surprising new phenomena as neutron stars and black holes did the once-sedate universe transform into an Einsteinian cosmos, filled with sources of titanic energy that can be understood only in the light of relativity. This book celebrates the hundredth anniversary of general relativity, uncovers how the black hole really got its name, and recounts the scientists' frustrating, exhilarating, and at times humorous battles over the acceptance of one of history's most dazzling ideas.

Yet nearly ten years after the so-called victory in Iraq, the West faces a terror threat unprecedented since the Cold War, as ISIL, Al Qaeda and their allies set out to build an empire of intolerance - a 21st-century theocracy with seventh-century values stretching from Portugal to Pakistan.We need to step-up the fightback - yet we're at risk of plunging into our enemies' trap. At home we are becoming suspicious societies, inflamed by the likes of Donald Trump and Marine Le Pen, where British Muslims fear being seen as the enemy within. Online, we're disorganised and lack the cohesion to fight extremist recruiters on the digital battlefront.And in the Middle East, we are without the coalition needed to isolate and undermine our enemy in the 21st-century battle of beliefs. From the frontline in Iraq to the streets of inner city Birmingham, Liam Byrne brings together fresh, grassroots research with young British Muslims, frank interviews with intelligence and police officers, and frontline reports from across the Middle East to offer not questions, but bold new answers to one of the biggest challenges of our time: how to bring down the black flag of extremism. Features Summary A timely examination of the issues surrounding the rise of Daesh and our reaction at home and abroad to the organisation.

Old hierarchies and institutions are collapsing. All the "givens" of civic life are no longer given. From the fracturing of the major political parties, to the spread of bottom-up movements like Black Lives Matter and $15 Now, citizens across the country and across the political spectrum are reclaiming power. It is no longer the exclusive domain of CEOs, political elites, and insiders from either political party. And the question that today's rising citizens have to face is: Are you ready? Do you understand power? And if you want to make change in the world, do you know how? The answers to all these questions are provided in Eric Liu's incisive book. In its pages, Liu lays out the elements and the strategies of citizen power, showing when to create a hashtag, when to call your Congressman, and when to take to the streets. (When you go, don't forget your camera.) Above all, Liu reminds us that *someone* always has power, which means if you're not participating, you're surrendering. Published in the early days of a new presidency, this book is not just a manual for power but an inspiring call to action. As Liu shows, voting is just one way of inciting change. So is protesting. What happens after the election, and after the march through the streets, is the real test of whether we the people can truly be we the powerful. Features Summary A handbook for how political power really works -- what it takes to make change happen, and most importantly, how active citizens can take possession of it.

For all curious readers, a lively introduction to radical ideas and discoveries that are transforming our knowledge of the universe This book provides a tour of the "greatest hits" of cosmological discoveries-the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place, filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is someone at the forefront of the research-an astrophysicist who literally creates maps of invisible matter in the universe. She not only explains for a wide audience the science behind these essential ideas but also provides an understanding of how radical scientific theories gain acceptance. The formation and growth of black holes, dark matter halos, the accelerating expansion of the universe, the echo of the big bang, the discovery of exoplanets, and the possibility of other universes-these are some of the puzzling cosmological topics of the early twenty-first century. Natarajan discusses why the acceptance of new ideas about the universe and our place in it has never been linear and always contested even within the scientific community. And she affirms that, shifting and incomplete as science always must be, it offers the best path we have toward making sense of our wondrous, mysterious universe. Format:Hardback
