One of the world's leading astronomers, Robert Kirshner, takes readers inside a lively research team on the quest that led them to an extraordinary cosmological discovery: the expansion of the universe is accelerating under the influence of a dark energy that makes space itself expand. In addition to sharing the story of this exciting discovery, Kirshner also brings the science up-to-date in a new epilogue. He explains how the idea of an accelerating universe--once a daring interpretation of sketchy data--is now the standard assumption in cosmology today.This measurement of dark energy--a quality of space itself that causes cosmic acceleration--points to a gaping hole in our understanding of fundamental physics. In 1917, Einstein proposed the cosmological constant to explain a static universe. When observations proved that the universe was expanding, he cast this early form of dark energy aside. But recent observations described first-hand in this book show that the cosmological constant--or something just like it--dominates the universe's mass and energy budget and determines its fate and shape.Warned by Einstein's blunder, and contradicted by the initial results of a competing research team, Kirshner and his colleagues were reluctant to accept their own result. But, convinced by evidence built on their hard-earned understanding of exploding stars, they announced their conclusion that the universe is accelerating in February 1998. Other lines of inquiry and parallel supernova research now support a new synthesis of a cosmos dominated by dark energy but also containing several forms of dark matter. We live in an extravagant universe with a surprising number of essential ingredients: the real universe we measure is not the simplest one we could imagine.

    The ability to duplicate that process in a lab, once thought impossible, may now be closer than we think. Today, teams of scientists around the world are being assembled by the boldest entrepreneurs, big business, and governments to solve what is the most difficult technological challenge humanity has ever faced: building the equivalent of a star on earth. If their plans to capture star power are successful, they will unlock thousands, potentially millions, of years of clean, carbon-free energy. Not only would controlled nuclear fusion help solve the climate crisis, it could also make other highly desired technological ambitions possible—like journeying to the stars. Given the rising alarm over deterioration of the environment, and the strides being made in laser and magnetic field technology, powerful momentum is gathering behind fusion and the possibilities it offers. In The Star Builders, award-winning young plasma physicist Arthur Turrell “offers an optimistic outlook for the future of fusion power and is adamant about the need to invest in it” (The New York Times). Turrell describes fascinating star machines with ten times as many parts as the NASA Space Shuttle, and structures that extend over 400 acres in an accessible and entertaining account, spotlighting the individuals, firms, and institutions racing for the finish line: science-minded entrepreneurs like Jeff Bezos and Peter Thiel, companies like Goldman Sachs and Google, universities like Oxford and MIT, and virtually every rich nation. It’s an exciting and game-changing international quest that will make all of us winners.

    Spanning ten historic years, from the discovery of nuclear fission in 1939 to ‘Joe-1’, the first Soviet atomic bomb test in August 1949, Atomic is the first fully realised popular account of the race between Nazi Germany, Britain, America and the Soviet Union to build atomic weapons.Drawing on declassified material such as MI6's Farm Hall transcripts, coded Soviet messages cracked by American cryptographers in the Venona project, and interpretations by Russian scholars of documents from the Soviet archives, Atomic presents a brilliant new account of the race to build humankind's most destructive weapon.Rich in personality, action, confrontation and deception, Jim Baggott’s book tells an epic story of science and technology at the very limits of human understanding.

    David Horowitz’s classic Why Israel is the Victim, updated by the author, sets the record straight about the basic truths of the Middle East conflict. In addition to restoring the authentic history of the region – a history of obsessive aggression first by Arab countries determined to physically annihilate the Jewish State and later by terror groups determined to destroy its will to survive and right to exist—this booklet brings the story up to date by showing the systematic way in which Hamas and Hezbollah, under Iran’s direction, have subverted peace in the Middle East. As Shillman Fellow Daniel Greenfield notes in his insightful introduction, this pamphlet “tells us why we should reject the “Blame Israel First” narrative that has so thoroughly saturated the mainstream media… It confronts the myth of Palestinian victimhood… and it delivers a rousing restatement of the true history of the hate that led us to all this.” America should be Israel’s protector. Instead, as David Horowitz notes, under the leadership of Barack Obama, it has become its prosecutor.

    --Carlo Rovelli, author of Seven Brief Lessons on Physics and Helgoland You've got questions: about space, time, gravity, and the odds of meeting your older self inside a wormhole. All the answers you need are right here.As a species, we may not agree on much, but one thing brings us all together: a need to know. We all wonder, and deep down we all have the same big questions. Why can't I travel back in time? Where did the universe come from? What's inside a black hole? Can I rearrange the particles in my cat and turn it into a dog?Researcher-turned-cartoonist Jorge Cham and physics professor Daniel Whiteson are experts at explaining science in ways we can all understand, in their books and on their popular podcast, Daniel and Jorge Explain the Universe. With their signature blend of humor and oh-now-I-get-it clarity, Jorge and Daniel offer short, accessible, and lighthearted answers to some of the most common, most outrageous, and most profound questions about the universe they've received.This witty, entertaining, and fully illustrated book is an essential troubleshooting guide for the perplexing aspects of reality, big and small, from the invisible particles that make up your body to the identical version of you currently reading this exact sentence in the corner of some other galaxy. If the universe came with an FAQ, this would be it.

    

    Unique in basing relativity on the Principle of Equivalence of Gravitation and Inertia over Riemannian geometry, this book explores relativity experiments and observational cosmology to provide a sound foundation upon which analyses can be made. Covering special and general relativity, tensor analysis, gravitation, curvature, and more, this book provides an engaging, insightful introduction to the forces that shape the universe.

    It features all the great names in science, including Pythagoras, Galileo, Newton, Darwin, and Einstein, as well as more recent contributors such as Rachel Carson, James Lovelock, and Stephen Hawking.This little book presents serious science simply, answering questions like:What is Pythagorean Theorem? What is the difference between circadian rhythms and the popular concept of biorhythms? What is Hawking’s Black Hole Theory? Who developed the World Wide Web?

    They signify the recognition that the interaction between science and religious reflection is not limited to those topics (such as cosmic history) concerning which the two disciplines offer complementary insights. It involves also an engagement with habits of thought which are natural in a culture greatly influenced by the success of science. To take this stance is not to submit to slavery to the spirit of the age, but simply to acknowledge that we view things from where we stand, with all the opportunities and limitations inherent in that particular perspective. . . . My concern is to explore to what extent we can use the search for motivated understanding, so congenial to the scientific mind, as a route to being able to make the substance of Christian orthodoxy our own. Of course, there are some revisions called for in the process, but I do not find that a trinitarian and incarnational theology needs to be abandoned in favour of a toned-down theology of a Cosmic Mind and an inspired teacher, alleged to be more accessible to the modern mind. A scientist expects a fundamental theory to be tough, surprising and exciting. "Throughout, my aim will be to seek an understanding based on a careful assessment of phenomena as the guide to reality. Just as I cannot regard science as merely an instrumentally successful manner of speaking which serves to get things done, so I cannot regard theology as merely concerned with a collection of stories which motivate an attitude to life. It must have its anchorage in the way things actually are, and the way they happen. . . . A bottom-up thinker is bound to ask, What makes you think this story is a verisimilitudinous account of Reality? The anchorage of Christianity in history is to be welcomed, despite its hazards. For me, the Bible is neither an inerrant account of propositional truth nor a compendium of timeless symbols, but a historically conditioned account of certain significant encounters and experiences. Read in that way, I believe it can provide the basis for a Christian belief with is certainly revised in the light of our twentieth-century insights but which is recognizably contained within an envelope of understanding in continuity with the developing doctrine of the Church throughout the centuries." - from the introduction

    Soon Gen Xers will be the only cohort of Americans who remember life as it was lived before the arrival of the Internet. They are, as Hennessey dubs them, “the last adult generation,” the sole remaining link to a time when childhood was still a bit dangerous but produced adults who were naturally resilient. More than a decade into the social media revolution, the American public is waking up to the idea that the tech sector’s intentions might not be as pure as advertised. The mountains of money being made off our browsing habits and purchase histories are used to fund ever-more extravagant and utopian projects that, by their very natures, will corrode the foundations of free society, leaving us all helpless and digitally enslaved to an elite crew of ultra-sophisticated tech geniuses. But it’s not too late to turn the tide. There’s still time for Gen X to write its own future. A spirited defense of free speech, eye contact, and the virtues of patience, Zero Hour for Gen X is a cultural history of the last 35 years, an analysis of the current social and historical moment, and a generational call to arms.
