Are we alone in the universe? It's a fundamental question for Earth-dwelling humankind. Are there other worlds like ours, out there somewhere? In Hidden in the Heavens, Jason Steffen, a former scientist on NASA's Kepler mission, describes how that mission searched for planets orbiting Sun-like stars—especially Earth-like planets circulating in Earth-like orbits.

Icy, rocky, sometimes dusty, always mysterious – comets and asteroids are among the Solar System's very oldest inhabitants, formed within a swirling cloud of gas and dust in the area of space that eventually hosted the Sun and its planets. Locked within each of these extra-terrestrial objects is the 4.6-billion-year wisdom of Solar System events, and by studying them at close quarters using spacecraft we can coerce them into revealing their closely-guarded secrets. This offers us the chance to answer some fundamental questions about our planet and its inhabitants.

Uma das mentes mais geniais do mundo moderno, Stephen Hawking guia o leitor na busca por respostas a algumas das maiores dúvidas da humanidade: Qual a origem do universo? Ele é infinito? E o tempo? Sempre existiu, ou houve um começo e haverá um fim? Existem outras dimensões além das três espaciais? E o que vai acontecer quando tudo terminar? Com ilustrações criativas e texto lúcido e bem-humorado, Hawking desvenda desde os mistérios da física de partículas até a dinâmica que movimenta centenas de milhões de galáxias por todo o universo.

«Has cambiado mi vida» es una frase muy común en los emails que Walter Lewin recibe a diario de fans cautivados por sus «videoclases» sobre la física. Durante cuarenta y tres años como profesor en el Instituto Tecnológico de Massachusetts, Lewin ha perfeccionado su peculiar arte de enseñar y de hacer de la física algo divertido. En Por amor a la física Lewin responde a preguntas curiosas y nos acompaña en un viaje maravilloso abriendo nuestros ojos a la belleza y al poder con los que la física puede revelar los mecanismos ocultos del mundo que nos rodea.

Interviews with physicists and chemists about their new books

The Chernobyl Disaster, which occurred in late April 1986, was the worst nuclear accident in history. It not only caused widespread radioactive contamination, but even more importantly, it claimed many lives and caused panic worldwide about the safety of nuclear power. In short, it changed the face of nuclear energy globally.

Beyond dares to imagine a fantastic future for humans in space - and then reminds us that we're already there. Human exploration has been an unceasing engine of technological progress, from the first homo sapiens to leave our African cradle to a future in which mankind promises to settle another world. Beyond tells the epic story of humanity leaving home - and how humans will soon thrive in the vast universe beyond the Earth.

Eric Scerri presents the intriguing stories of these seven elements - protactinium, hafnium, rhenium, technetium, francium, astatine and promethium. The book follows the historical order of discovery, roughly spanning the two world wars, beginning with the isolation of protactinium in 1917 and ending with that of promethium in 1945. For each element, Scerri traces the research that preceded the discovery, the pivotal experiments, the personalities of the chemists involved, the chemical nature of the new element, and its applications in science and technology.

Over the past few years, devastating tsunamis off the coast of the Indian Ocean have killed hundreds of thousands of people. Even more alarmingly, scientists predict that these tsunamis, as well as a series of earthquakes and volcanic eruptions, will be striking with even greater frequency and may eventually threaten Hawaii, California, and Oregon.

Is it worthwhile to invest one hour of your time to learning about nuclear war survival? The devastating events in Hiroshima and Nagasaki proved that there will always be survivors in the aftermath of a nuclear explosion. They did a few things right that made all the difference, and after listening to this short audiobook, you’ll know these critical steps too....

Now in its fourth edition, this low-cost astronomy audio-textbook is designed for a one-semester introductory astronomy course aimed at non-science majors and future teachers. This new edition brings the latest astronomical discoveries together with cutting-edge teaching and learning strategies designed specifically to improve student learning and retention.

True life accounts and heartfelt testimonies from people who have had near-death experiences which have changed their lives forever

The real nature of time is still a mystery, even after thousands of years of philosophers and scientists analyzing it and proposing theories about it. Prophecy has existed for most of humanity’s time on Earth, and there is a lot of reason to think that seeing the future does reveal some of what happens and is about to happen. I also wrote two books on this subject, including the history of prophecy and my own experiences.

Les grandes théories du cosmos : du Big Bang aux trous noirs. Premier livre de Stephen Hawking écrit à l'intention du non-spécialiste, succès incontournable dès sa parution, "Une brève histoire du temps" présente dans un langage simple et accessible les développements contemporains de l'astrophysique. Retraçant les grandes théories du cosmos, de Galilée et Newton à Einstein et Poincaré.

A collection of chapters from the previous five volumes in the Rational Science series. We discuss the difference between objects and concepts, hypothesis and theory, and science and technology. We learn about light, time, and mass, the Big Bang Theory, black holes, and Mach’s principle. We find out about dinosaurs and why they were so big. We look at a couple hypotheses on planetary and solar system formation. From atom to sun, we learn to think about reality in new ways.

Our most recent scientific theory states that 99 percent of the multiverse is invisible to us. In fact, every current physics textbook makes this claim. Therefore, if only 1 percent of the multiverse is visible to us, the question becomes: When you view yourself in a mirror, are you truly seeing 100 percent of yourself...or just 1 percent? Best-selling author Ishan Rami is joined by Dan Howe to answer this question and more in their new audiobook: Your Invisible Body and the Quantum Universe.

Hör-Zeit in der Weite des Universums - Zeit für eine kurze Geschichte der Physik. Ist das Weltall grenzenlos oder hat es einen Anfang? Was bedeuten Raum und Zeit im unfassbaren Universum? Fragen, die schon Kinder beschäftigen, haben in der Geschichte der Physik zu aufregenden Theorien geführt. Von Aristoteles bis zur Quantenphysik sorgt Stephen Hawking in "Eine kurze Geschichte der Zeit" für Überblick.

We all know about magnetism right? But hold the phone! Where does this force come from in the first place? Did magnetism play a role in the creation of the universe? Why is this force important in everything from atomic structure to the way solar flares form?

The Large Hadron Collider is the biggest, and by far the most powerful, machine ever built. A project of CERN, the European Organization for Nuclear Research, its audacious purpose is to re-create, in a 16.5-mile-long circular tunnel under the French-Swiss countryside, the immensely hot and...

Gravity - Holy Spirit - Love - The Force Binding The Universe Together is a book about what gravity is and how it really works in the world around us. It is a new look at what gravity really is and how it works, changing our understandings of the universe we live within. It uses real world examples of comets and hurricanes and twisters and other moving objects in space and on earth to prove its theories. It relates how gravity in material objects is like love in human relationships and between man and God.
