And yet. What is our place in the billion-year history of the universe? How do we connect with the intricate web of life on Earth? In Journey of the Universe, Brian Thomas Swimme and Mary Evelyn Tucker tell the epic story of the universe from an inspired new perspective, weaving the findings of modern science together with enduring wisdom found in the humanistic traditions of the West, China, India, and indigenous peoples.
Journey of the Universe transforms how we understand our origins and envision our future. Though a little book, it tells a big story one that inspires hope for a way in which Earth and its human civilizations could flourish together. Book Summary: "What is the origin of the universe? Are we alone in the Universe? The first part discusses the origins of everything, from the Big Bang to humankind. It follows the long course of evolution — from original matter to the formation of more complex structures, from the furthest galaxies to the nearest stars, from planets to organic molecules, from the first and most elementary forms of life through to the reptiles, the dinosaurs and the advent of man.
The second part traces the history of the Earth and evaluates the risks of extinction in the future as predicted by scientists. Is the Earth the only habitable planet in the Universe?
This question initiates the discussion on the importance of the Earth's position in the solar system and the significance of our geologically alive planet. The final part is dedicated to the search for extraterrestrial beings with identifiable life forms. It also describes attempts for searching, from the past to the near future.
This remarkable book provides the best answers we have to the epic questions about us and our place in the universe. Book Summary: Does the universe have the character it has because of design? In this collection of essays first presented at a symposium sponsored by the Canadian Institute for Advanced Research and the Royal Society of Canada, seventeen scientists and philosophers re-examine the "Argument by Design" in light of current scientific theories.
Scientists in such diverse fields as cosmology, physics, geology, biology, and psychology provide syntheses of the state of their respective disciplines with regard to questions such as the origin or evolution of the universe and of life, the interaction of life and terrestrial environment, and verbal communication in prehumans. Contributions by philosophers cover such areas as arguments for a designer and the question of whether nature's laws and initial conditions could be viewed as "fine tuned" for the production of life.
Many of the chapters demonstrate the awe-inspiring success of modern science in explaining the universe in terms of fairly straightforward natural laws, countering those versions of the design argument which try to find evidence of God's activities in the supposed failures of scientific laws to cover various phenomena. Book Summary: Evolution of Stars and Stellar Populations is a comprehensive presentation of the theory of stellar evolution and its application to the study of stellar populations in galaxies.
Taking a unique approach to the subject, this self-contained text introduces first the theory of stellar evolution in a clear and accessible manner, with particular emphasis placed on explaining the evolution with time of observable stellar properties, such as luminosities and surface chemical abundances.
This is followed by a detailed presentation and discussion of a broad range of related techniques, that are widely applied by researchers in the field to investigate the formation and evolution of galaxies.
This book will be invaluable for undergraduates and graduate students in astronomy and astrophysics, and will also be of interest to researchers working in the field of Galactic, extragalactic astronomy and cosmology. Book Summary: Bestselling author and acclaimed physicist Lawrence Krauss offers a paradigm-shifting view of how everything that exists came to be in the first place.
What was there before it? What will the future bring? And finally, why is there something rather than nothing? Provocative, challenging, and delightfully readable, this is a game-changing look at the most basic underpinning of existence and a powerful antidote to outmoded philosophical, religious, and scientific thinking.
Book Summary: Earth and Cosmos presents a comprehensive view of the many connections between the environment of Man on Earth and the environment of the Earth in the cosmos. Topics covered range from matter, radiation, and the basic forces of nature to Earth's relation to the universe, the galaxy, and the sun. The energy balance and global circulation of the atmosphere are also discussed, along with continents, oceans, and climate. This book is comprised of 13 chapters and begins with an overview of the environment of Man on Earth, with emphasis on the Earth's chemical composition and how it is related to both cosmic and terrestrial processes; the radiation environment at the Earth's surface and above; how the atmosphere interacts with both solar and terrestrial radiation; and climate.
The following chapters explore matter, radiation, and the laws of nature in relation to the universe; how the terrestrial environment is related to the structure of the universe as a whole; how the composition of the solar system and the Earth reflects the history of the galaxy; and the stability of the Earth's environment.
The origins of life on Earth and the impact of human activities on the planet are also considered. The last chapter speaks of the future of humanity, and notably of the problem of the population explosion and its consequences. This monograph will be of interest to students, astronomers, planetary scientists, astrophysicists, biologists, chemists, and geologists. Book Summary: A paradigm-shifting blend of science, religion, and philosophy for agnostic, spiritual-but-not-religious, and scientifically minded readers Many people are fed up with the way traditional religion alienates them: too easily it can perpetuate conflict, vilify science, and undermine reason.
Nancy Abrams, a philosopher of science, lawyer, and lifelong atheist, is among them. And yet, when she turned to the recovery community to face a personal struggle, she found that imagining a higher power gave her a new freedom. Intellectually, this was quite surprising. Meanwhile her husband, famed astrophysicist Joel Primack, was helping create a new theory of the universe based on dark matter and dark energy, and Abrams was collaborating with him on two books that put the new scientific picture into a social and political context.
This God did not create the universe—it created the meaning of the universe. A God that could be real, Abrams shows us, is what humanity needs to inspire us to collectively cooperate to protect our warming planet and create a long-term civilization. Book Summary: The popular belief that a scientific understanding of reality is incompatible with a Christian one is simply wrong.
Some Christian understandings of reality do conflict with some scientific understandings. But a thoroughly rational Christian understanding of the origin and history of the universe will be informed by the best scientific theories and the "facts" founded on them. This book weaves a narrative of the origin and history of the universe from the perspective of contemporary science with a Christian understanding of God and of God's role in the origin and history of the universe.
At the center of this integrated narrative is the view that God, who is pure, unbounded Love, is Creator: the zest for life in the universe comes from God, and God is the source of Truth, Beauty, and Goodness in the universe.
God is amazed and delighted at what God-and-the-world has created; God is saddened by ways creatures have fallen short of pure, unbounded Love, Truth, Beauty, and Goodness; and God's pure, unbounded Love keeps on trying to persuade all creatures toward Truth, Beauty, and Goodness.
Book Summary: Living with the Stars tells the fascinating story of what truly makes the human body. The body that is with us all our lives is always changing. We are quite literally not who we were years, weeks, or even days ago: our cells die and are replaced by new ones at an astonishing pace. The entire body continually rebuilds itself, time and again, using the food and water that flow through us as fuel and as construction material. What persists over time is not fixed but merely a pattern in flux.
We rebuild using elements captured from our surroundings, and are thereby connected to animals and plants around us, and to the bacteria within us that help digest them, and to geological processes such as continental drift and volcanism here on Earth.
We are also intimately linked to the Sun's nuclear furnace and to the solar wind, to collisions with asteroids and to the cycles of the birth of stars and their deaths in cataclysmic supernovae, and ultimately to the beginning of the universe. Our bodies are made of the burned out embers of stars that were released into the galaxy in massive explosions billions of years ago, mixed with atoms that formed only recently as ultrafast rays slammed into Earth's atmosphere.
All of that is not just remote history but part of us now: our human body is inseparable from nature all around us and intertwined with the history of the universe. We know the universe had a beginning. With the Big Bang, it expanded from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life as we know it.
But what happens to the universe at the end of the story? And what does it mean for us now? Katie Mack has been contemplating these questions since she was a young student, when her astronomy professor informed her the universe could end at any moment, in an instant.
This revelation set her on the path toward theoretical astrophysics. Guiding us through cutting-edge science and major concepts in quantum mechanics, cosmology, string theory, and much more, The End of Everything is a wildly fun, surprisingly upbeat ride to the farthest reaches of all that we know. Book Summary: Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe.
It is an inherently interdisciplinary field that encompasses astronomy, biology, geology, heliophysics, and planetary science, including complementary laboratory activities and field studies conducted in a wide range of terrestrial environments. Combining inherent scientific interest and public appeal, the search for life in the solar system and beyond provides a scientific rationale for many current and future activities carried out by the National Aeronautics and Science Administration NASA and other national and international agencies and organizations.
Requested by NASA, this study offers a science strategy for astrobiology that outlines key scientific questions, identifies the most promising research in the field, and indicates the extent to which the mission priorities in existing decadal surveys address the search for life's origin, evolution, distribution, and future in the universe. This report makes recommendations for advancing the research, obtaining the measurements, and realizing NASA's goal to search for signs of life in the universe.
In Your Inner Fish, Neil Shubin delved into the amazing connections between human bodies—our hands, heads, and jaws—and the structures in fish and worms that lived hundreds of millions of years ago. In The Universe Within, with his trademark clarity and exuberance, Shubin takes an even more expansive approach to the question of why we look the way we do.
As he moves from our very molecular composition a result of stellar events at the origin of our solar system through the workings of our eyes, Shubin makes clear how the evolution of the cosmos has profoundly marked our own bodies. Book Summary: We know the universe has a history, but does it also have a story of self-creation to tell? Yes, in Roy R. He offers a compelling narrative of how the universe—with no instruction other than its own laws—evolved into billions of galaxies and gave rise to life, including humans who have been trying for millennia to comprehend it.
Far from being a random accident, the universe is hard at work, extracting order from chaos. Making use of the best current science, Gould turns what many assume to be true about the universe on its head.
The cosmos expands inward, not outward. Gravity can drive things apart, not merely together. Jawless fish probably evolved around mya. Sea weeds and few plants existed probably around mya. We are told that the first organisms that invaded land were plants. They were widespread on land when animals invaded land. Fish with stout and strong fins could move on land and go back to water.
This was about mya. These animals called lobefins evolved into the first amphibians that lived on both land and water. These were ancestors of modern day frogs and salamanders.
The amphibians evolved into reptiles. They lay thick-shelled eggs which do not dry up in sun unlike those of amphibians. Again we only see their modern day descendents, the turtles, tortoises and crocodiles.
In the next million years or so, reptiles of different shapes and sizes dominated on earth. Giant ferns pteridophytes were present along with reptiles but they all fell to form coal deposits slowly. Some of these land reptiles went back into water to evolve into fish like reptiles probably mya e.
The land reptiles were, of course, the dinosaurs. The biggest of them were Tyrannosaurus and Ultrasaurus. About 65 mya, the dinosaurs suddenly disappeared from the earth. We do not know the true reason. Some say climatic changes killed them. Some say most of them evolved into birds. The truth may live in between. Small sized reptiles of that era still exist today.
The first mammals were like shrews. Their fossils are small sized. Mammals were more intelligent in sensing and avoiding danger at least. When reptiles came down mammals took over this earth. T here were in South America mammals resembling horse, hippopotamus, bear, rabbit, etc. Due to continental drift , when South America joined North America, these animals were overridden by North American fauna.
Due to the same continental drift pouched mammals of Australia survived because of lack of competition from any other mammal. With reference to the evolution of living organisms, which one of the following sequences is correct? They were hairy and walked like gorillas and chimpanzees. Ramapithecus was more man-like while Dryopithecus was more ape-like. Few fossils of man-like bones have been discovered in Ethiopia and Tanzania. These revealed hominid features leading to the belief that about mya, man-like primates walked in eastern Africa.
They were probably not taller than 4 feet but walked up right. Two mya, Australopithecines probably lived in East African grasslands. Evidence shows they hunted with stone weapons but essentially ate fruit. Some of the bones among the bones discovered were different.
This creature was called the first human-like being the hominid and was called Homo habilis. The brain capacities were between cc. They probably did not eat meat. Fossils discovered in Java in revealed the next stage, i. Homo erectus had a large brain around cc. Homo erectus probably ate meat. The Neanderthal man with a brain size of cc lived in near east and central Asia between 1,00,, years back. They used hides to protect their body and buried their dead.
This book captures, in a series of questions, the essential scientific challenges that constitute the frontier of Earth science at the start of the 21st century.
Book Summary: Driven by discoveries, and enabled by leaps in technology and imagination, our understanding of the universe has changed dramatically during the course of the last few decades.
The fields of astronomy and astrophysics are making new connections to physics, chemistry, biology, and computer science. Based on a broad and comprehensive survey of scientific opportunities, infrastructure, and organization in a national and international context, New Worlds, New Horizons in Astronomy and Astrophysics outlines a plan for ground- and space- based astronomy and astrophysics for the decade of the 's.
Realizing these scientific opportunities is contingent upon maintaining and strengthening the foundations of the research enterprise including technological development, theory, computation and data handling, laboratory experiments, and human resources. New Worlds, New Horizons in Astronomy and Astrophysics proposes enhancing innovative but moderate-cost programs in space and on the ground that will enable the community to respond rapidly and flexibly to new scientific discoveries.
The book recommends beginning construction on survey telescopes in space and on the ground to investigate the nature of dark energy, as well as the next generation of large ground-based giant optical telescopes and a new class of space-based gravitational observatory to observe the merging of distant black holes and precisely test theories of gravity. New Worlds, New Horizons in Astronomy and Astrophysics recommends a balanced and executable program that will support research surrounding the most profound questions about the cosmos.
The discoveries ahead will facilitate the search for habitable planets, shed light on dark energy and dark matter, and aid our understanding of the history of the universe and how the earliest stars and galaxies formed. The book is a useful resource for agencies supporting the field of astronomy and astrophysics, the Congressional committees with jurisdiction over those agencies, the scientific community, and the public.
Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience.
