Science Cosmology

Un Univers en expansion - La cosmologie est l'étude de l'Univers dans son ensemble. En expansion depuis 15 milliards d'années, son histoire est jalonnée d'événements cosmiques : fabrication de la matière, génération du rayonnement cosmologique, apparition des galaxies... La cosmologie est aujourd'hui devenue une science, relativiste depuis le début du XX° siècle.Une histoire de nos nos connaissances sur l'Univers. Marc Lachièze-Rey retrace ici les grandes lignes de l'évolution des idées et des principes qui fondent nos connaissances sur l'Univers.

This is an indispensable guide to physics that offers readers an overview of the most popular physics topics written in an accessible, irreverent, and engaging manner while still maintaining a tone of wry skepticism. Even the novice will be able to follow along, as the topics are addressed using plain English and (almost) no equations. Veterans of popular physics will also find their nagging questions addressed, like whether the universe can expand faster than light.

Un cibo non troppo caldo e non troppo freddo, un letto non troppo morbido e non troppo duro: ecco cosa vuole la giovane protagonista della fiaba "Riccioli d'oro e i tre orsi", qualcosa di "proprio giusto". Sembra bizzarro, eppure l'astrobiologia usa lo stesso criterio nella ricerca di possibili forme di vita nello spazio. Tanto che si chiama "Fascia Riccioli d'oro" la zona abitabile di un sistema stellare, lo spazio in cui si trovano i pianeti che possiedono le caratteristiche necessarie allo sviluppo della vita: presenza di acqua, temperature non eccessivamente calde o fredde.

¿Cuáles son los mayores retos con los que se presenta el planeta, cuáles las mayores amenazas, dónde buscar la solución a los descomunales problemas con los que se enfrenta nuestra generación y las futuras? El origen y evolución del universo, la naturaleza del tiempo, la estructura de la materia, el infinito,las estrellas fugitivas, las ondas gravitacionales…Estos son algunos de los grandes temas que Rafael Bachiller aborda en este libro tanto desde un punto de vista científico como desde una perspectiva filosófica y humanista.

Rope Hypothesis and Thread Theory is based on Bill Gaede's Rope Hypothesis. We apply the rope model to questions such as, what is gravity, light, electricity, and magnetism? What is thermodynamics? What is the difference between light and sound? What is plasma? How do batteries, antennas, and cathode ray tubes work? What is the difference between fundamental and composite objects? Does size scale make a difference when it comes to motion, friction, bending, stretching, and tension?

Sustainability has become a compelling topic of domestic and international debate as the world searches for effective solutions to accumulating ecological problems. In Return to Nature? An Ecological Counterhistory, Fred Dallmayr demonstrates how nature has been marginalized, colonized, and abused in the modern era.

In the sixteenth century, Nicolaus Copernicus dared to go against the establishment by proposing that Earth rotates around the Sun. Having demoted Earth from its unique position in the cosmos to one of mediocrity, Copernicus set in motion a revolution in scientific thought. This perspective has influenced our thinking for centuries. However, recent evidence challenges the Copernican Principle, hinting that we do in fact live in a special place, at a special time, as the product of a chain of unlikely events.

We have long fantasized about finding life on planets other than our own. Yet even as we become aware of the vast expanses beyond our solar system, it remains clear that Earth is exceptional. The question is: Why? In Lucky Planet, astrobiologist David Waltham argues that Earth’s climate stability is what makes it uniquely able to support life, and it is nothing short of luck that made such conditions possible. The four-billion-year stretch of good weather that our planet has experienced is statistically so unlikely that chances are slim that we will ever encounter intelligent extraterrestrial others.

Fra tutte le teorie scientifiche, la relatività è quella che più ci affascina e ci sconcerta. Andando contro la nostra rassicurante percezione del mondo, ci costringe a prendere atto che spazio e tempo non sono due dimensioni fisse e separate, ma si contraggono e si dilatano, sfumando l'una nell'altra, fino a perdere la loro individualità. La realtà è, dunque, molto più strana di quello che appare. Tutto ciò può sembrare misterioso o comprensibile solo agli addetti ai lavori. Ma non è così.

Black holes are the most extreme objects in the universe, and yet they are ubiquitous. Frighteningly enigmatic, these dark giants continue to astound even the scientists who spend their careers studying them. Einstein’s Monsters reveals how our comprehension of black holes is intrinsically linked to how we make sense of the universe and our place within it. From the small questions to the big ones - from the tiniest particles to the nature of space-time itself - black holes might be the key to a deeper understanding of the cosmos.

In Astronomy’s Limitless Journey, astrophysicist Günther Hasinger takes the reader on a journey to the far reaches of the universe?an exciting time travel that begins with the incredibly hot fireball of the Big Bang roughly 13.8 billion years ago and ends in distant eons with its cold, dark demise. In between lie the times in which extensive structures, galaxies, stars, and planets form. As the field of astrophysics and cosmology experiences a “golden age” due to larger telescopes, faster computers, and more sophisticated algorithms, fundamental changes are taking place in our understanding of space and time and of the origin and future of our universe. Hasinger thoroughly explains these fascinating revelations and describes the methods utilized in modern astrophysics.

The European Space Agency released a map of the afterglow of the big bang map, which contains anomalies that challenge our understanding of the universe. This is the first book to address what will be an epoch-defining scientific paradigm shift. Will we ever know what happened before the big bang? What's at the bottom of a black hole? Are there universes beyond our own? Does time exist? Are the once immutable laws of physics changing?

“Cosmos” comes from a Greek word for an orderly and systematic universe. In this book, we present the most riveting discoveries and mind-bending ideas about our cosmic home, from what we know of the origins of the universe and the cartography of space to the most bizarre phenomena and the search for life. Discussions include the possibility that the big bang was the consequence of a black hole in a fourth spatial dimension, that cosmic ripples created infinite universes, that entangled black holes could act as wormhole-like passageways through space, and much more.

This compelling book describes how the Big Bang theory arose, how it has evolved, and why it is the best theory so far to explain the current state of the universe. In addition to understanding the birth of the cosmos, listeners will learn how the theory stands up to challenges and what it fails to explain. Karen Fox provides clear answers to some of the hardest questions including: Why was the Big Bang theory accepted to begin with? Will the Big Bang theory last into the next century or even the next decade? Is the theory at odds with new scientific findings?

Os grandes mistérios e maravilhas do céu noturno sempre nos fascinaram, intrigaram e divertiram, desde os primeiros passos na Terra. Hoje, continuamos nos esforçando para entender o nosso lugar no cosmos. O século 20 foi palco de importantes e assombrosas descobertas sobre o nosso próprio planeta, o sistema solar, as estrelas e as galáxias. Contudo, ainda buscamos respostas para inúmeras questões, e essa busca nos proporciona uma valiosa compreensão da vastidão e das infinitas possibilidades do espaço universal que ainda estamos por descobrir.

In the early 17th century, Galileo broke free from the hold of ancient Platonic and Aristotelian philosophy. He drastically changed the framework through which we view the natural world when he asserted that we should base our theory of reality on what we can observe rather than pure thought. In the process, he invented what we would come to call science. This set the stage for all the breakthroughs that followed - from Kepler to Newton to Einstein.

Book 1: is an inquiry and review of humanity's continual effort to gain hold of its legacy which was willed by God and passed on by many great souls. It asks many questions and gives suggestive answers to promote thought. It is like having a conversation with the author. What good is a mind if we don't use it?

Although it is widely understood that energy and water are the world’s two most critical resources, their vital interconnections and vulnerabilities are less often recognized. This farsighted audiobook offers a new, holistic way of thinking about energy and water - a big picture approach that reveals the interdependence of the two resources, identifies the seriousness of the challenges, and lays out an optimistic approach with an array of solutions to ensure continuing sustainability.
