In just fifteen minutes a day, you can master the 52 most important verses in the Bible in a year.…
While there are lots of one-year Bible reading plans, few help you understand the words that you're reading. What if we could introduce you to a Bible reading plan that would dramatically increase your mastery of the Bible in one year? Mark Moore coaches you through 52 of the Bible's most important verses. These are the "core" of the Bible. Each verse clears the path to master and manage dozens of other verses that run along the same principle path. At the end of this journey, you will move from curiosity about the Bible to competence in the Bible. It is the quickest onramp to understanding the whole of God's Word for your life.Par Randall Munroe. 2019

#1 New York Times bestsellers What If? and Thing Explainer For any task you might want to do, there's a right way, a wrong way, and a way so monumentally bad that no one would ever try it. How To is a guide to the third kind of approach. It's full of highly impractical advice for everything from landing a plane to digging a hole. Bestselling author and cartoonist Randall Munroe explains how to predict the weather by analyzing the pixels of your Facebook photos. He teaches you how to tell if you're a baby boomer or a 90's kid by measuring the radioactivity of your teeth. He offers tips for taking a selfie with a telescope, crossing a river by boiling it, and getting to your appointments on time by destroying the Moon. And if you want to get rid of the book once you're done with it, he walks you through your options for proper disposal, including dissolving it in the ocean, converting it to a vapor, using tectonic plates to subduct it into the Earth's mantle, or launching it into the Sun. By exploring the most complicated ways to do simple tasks, Munroe doesn't just make things difficult for himself and his readers. As he did so brilliantly in What If?, Munroe invites us to explore the most absurd reaches of the possible. Full of clever infographics and amusing illustrations, How To is a delightfully mind-bending way to better understand the science and technology underlying the things we do every day.Par Sean Carroll. 2019
Caltech physicist and New York Times bestselling author Sean Carroll shows that there are multiple copies of you. And everyone…
else. Really. Something Deeply Hidden begins with the news that physics is in a crisis. Quantum mechanics underlies all of modern physics but major gaps in the theory have been ignored since 1927. Science popularizers keep telling us how weird it is, how contradictory, how impossible it is to understand. Academics discourage students from working on the "dead end" of quantum foundations. Putting his professional reputation on the line, Carroll says that crisis can now come to an end. We just have to accept that there is more than one of us in the universe. There are many, many Sean Carrolls. Many of every one of us. The Many Worlds Theory of quantum behavior says that every time there is a quantum event, a world splits off with everything in it the same, except in that other world the quantum event didn't happen. Since the beginning of the universe about fourteen billion years ago, this has happened about ten to the tenth to the one-hundredth power times. Step-by-step in Carroll's uniquely lucid way, he sets out the major objections to this utterly mind-blowing notion until his case is inescapably established. The holy grail of modern physics is reconciling quantum mechanics with Einstein's general relativity- his theory of curved spacetime. Carroll argues that our refusal to face up to the mysteries of quantum mechanics has blinded us, and that spacetime and gravity naturally emerge from a deeper reality called the wave function. No book for a popular audience has attempted to make this radical argument. We're on the threshold of a new way of understanding the cosmos.Par Vivian Mabuni. 2019
From a veteran Cru staff member, Bible teacher, and popular speaker comes an invitation for Christian women to discover how…
yielding ourselves wholly to God, especially in the midst of challenging circumstances, lends new purpose to our lives. We know that the center of God's will is the best place to be, but surrender is easier said than done. A host of hurdles, from busyness and bitterness to complacency and control, can prevent us from moving where He directs. In this challenging yet warmhearted book, Vivian Mabuni provides an authentic look at what it means to willingly risk saying yes to whatever God asks-and highlights a practical path to the deeper joy of a yielded life."A timely and groundbreaking take on the roots of the Christian church and its place in the entirety of God's…
kingdom...? There is no better time than now to learn about and become firmly grounded within your spiritual heritage." -from the foreword by Perry Stone The early church was made up of Jewish and Gentile followers of Jesus, and the church's culture was rooted in Judaism and a Jewish understanding of God's relationship to His people. Over time, however, Christianity became increasingly more Roman than Jewish, and the church lost its identity. Rabbi Curt Landry's personal story is remarkably similar. Born to a Jewish mother and a Catholic father, Landry was put up for adoption, and for more than thirty years he had no understanding of his heritage, his roots, or who his parents were. But when he discovered the truth of his story, his life changed completely. The key to a life of power and purpose is understanding who you are. In this revelatory book, Curt Landry helps Christians discover their roots in Judaism, empowering them to walk in the revelation of who they really are and who they are born to be.Reclaiming Our Forgotten Heritagereveals the mysteries of the church, letting Christians grasp the power that comes from connecting with their true identity.An astonishing exploration of planet formation and the origins of life by one of the world's most innovative planetary geologists.In…
1959, the Soviet probe Luna 3 took the first photos of the far side of the moon. Even in their poor resolution, the images stunned scientists: the far side is an enormous mountainous expanse, not the vast lava-plains seen from Earth. Subsequent missions have confirmed this in much greater detail. How could this be, and what might it tell us about our own place in the universe? As it turns out, quite a lot. Fourteen billion years ago, the universe exploded into being, creating galaxies and stars. Planets formed out of the leftover dust and gas that coalesced into larger and larger bodies orbiting around each star. In a sort of heavenly survival of the fittest, planetary bodies smashed into each other until solar systems emerged. Curiously, instead of being relatively similar in terms of composition, the planets in our solar system, and the comets, asteroids, satellites and rings, are bewitchingly distinct. So, too, the halves of our moon. In When the Earth Had Two Moons, esteemed planetary geologist Erik Asphaug takes us on an exhilarating tour through the farthest reaches of time and our galaxy to find out why. Beautifully written and provocatively argued, When the Earth Had Two Moons is not only a mind-blowing astronomical tour but a profound inquiry into the nature of life here-and billions of miles from home.Par Étienne Klein. 2018

comment approcher une façon de penser et de créer à nulle autre pareille ? Étienne Klein est parti sur ses traces, il s'est attaché aux époques et aux villes où le destin d'Einstein a basculé : Aarau où, à seize ans, Einstein se demande ce qu'il se passerait s'il chevauchait un rayon de lumière ; Zurich, où il devient ingénieur en 1901 et se passionne pour la physique expérimentale ; Berne où, entre mars et septembre 1905, il publie cinq articles, dont celui sur la relativité restreinte qui révolutionnera les relations de l'espace et du temps, tout en travaillant à l'Office fédéral de la propriété intellectuelle ; Prague où, en 1912, il a l'idée que la lumière est déviée par la gravitation, esquissant ainsi la future théorie de la relativité générale. Puis Bruxelles, Anvers et, enfin, Le Coq-sur-Mer où, en 1933, Einstein se réfugie quelques mois avant de quitter l'Europe pour les États-Unis. Définitivement. "Par Yann Verdo. 2018

du violon ou fumait la pipe, et ces deux objets ne sont certes pas pour rien dans l'élaboration de ses théories. Et même si chacun de nous n'atteint pas des sphères de la pensée aussi vertigineuses que lui, l'art de penser à côté est accessible à tous. Yann Verdo le montre ici, en pratiquant la physique en amateur averti, et en nous invitant à plonger avec lui dans la physique quantique, la relativité générale et la logique. De ses rencontres imaginaires avec Einstein, Cantor et Gödel résultent une familiarité nouvelle avec ces individus hors du commun, et une compréhension profonde des grands thèmes - le temps, l'infini, la matière - qu'ils ont révolutionnésPar Alan Q Morton. 2006

théories. Puis il explique la relativité et son rôle dans notre vie quotidienne, pour ensuite analyser les théories de la relativité spéciale et de la relativité générale. Il poursuit en décrivant la façon dont ces idées étonnantes ont ouvert la voie à une toute nouvelle interprétation des forces de l'univers, de la puissance que recèle le noyau d'un atome au comportement des corps célestes qui peuplent l'espace. -- 4e de couvPar Stephen Hawking, Leonard Mlodinow. 2006

Hawking's worldwide bestseller A Brief History of Time remains a landmark volume in scientific writing. But for readers who have asked for a more accessible formulation of its key concepts-the nature of space and time, the role of God in creation, and the history and future of the universe-A Briefer History of Time is Professor Hawking's response. Although "briefer," this book is much more than a mere explanation of Hawking's earlier work. A Briefer History of Time both clarifies and expands on the great subjects of the original, and records the latest developments in the field-from string theory to the search for a unified theory of all the forces of physics. Thirty-seven full-color illustrations enhance the text and make A Briefer History of Time an exhilarating and must-have addition in its own right to the great literature of science and ideas.
