    Al Seckel has rescued many of Bertrand Russell's best essays on religion, free thought, and nationalism from their resting places in obscure pamphlets, hard-to-find books, and out-of print periodicals to form a superb compilation.

    Did some divine power create the first couple? Religious scriptures the world over aver that one or the other god gave birth to humans, but science has not yet identified any supernatural power that created and governed human beings. Did primeval humans come up with the idea of gods to help them cope with their fears? Could it be that they attributed natural phenomena — unfathomable and frightening to them — to the working of invisible gods? The Evolution of Gods uses modern science to explain why, when and how religions and gods became the desirable explanations of the inexplicable events. It describes anthropological and historical facts about the evolution of religions and gods, in a simple and straightforward manner, to assert that human imagination created gods, and not the other way around.The book begins with the epoch when the human race came into being, between 400,000 and 200,000 years ago. Around 100,000 years ago, humans invented language and began to discuss and analyze each happening around them. Whatever they could not comprehend, their priest attributed to some unseen power. At one point in time, we do not know exactly when it happened, humankind began an activity called worship. Humans began to worship each seen or unseen power, which was beyond their control, but could either harm or help them. They believed that worship protected them and sought the blessings of that power. Priests all over the world invented almost identical methods of worship, such as folding their hands, bowing, kneeling, flowers offering, prayers and sacrifices. For example, anthropologists have drawn that ancient humans had largely inadequate protection against cold; their survival largely deepened upon available sunlight—something beyond their control. In that scenario, solar worship was a logical outcome. In a similar manner, the humans found thunder and lightning inexplicable and frightening. Gradually, they began to worship the sky as god. There is enough historical evidence to assert that the ancestors of Hindus, Buddhists, Jews, Christians and Muslims, before their religions came into practice, worshipped the sun and the sky. Thus, history demonstrates that whenever humankind faced a new challenge, priests invented a more useful deity and consigned the older one to oblivion. For example, around three thousand years ago, cultivation provided several facilities to humans that paved the way for a population explosion. At the same time, farming exposed people to pets, rodents, mosquitoes, houseflies and parasites. All these factors together gave rise to altogether new diseases such as cholera, tuberculosis, typhoid and plague. Apart from these diseases, population explosion also gave rise to social diseases such as poverty, inequality, injustice, crime and exploitation. All these together forced people to lead a miserable life no better than hell. Around this time, a few geniuses such as the Buddha, Moses and Jesus discovered the causes and remedies of human sufferings. For example, Moses suggested ten morals, sacrifices and prayers to protect people from their miseries. The contemporary priests transcribed prayers, rituals, myths, allegories and morals preached by these prophets after their death. The Holy Scriptures, such as the Vedas and the Bible were the compilations of such writings. These books advised worship, sacrifices, magic or morals to eradicate human miseries. The Suffering masses had no option but to follow those advices. These scriptures fashioned the organized religions of today. Let us think for a moment why there are many religions and there is only one science on the Earth. There is one concrete reason behind this irony; about one thing or concept there is only one truth but there can be many lies. This book is an effort to light a candle in the darkest corner of human consciousness.

    

    Opens up not only the exhilarating truths that science reveals of the birth of the universe, but how these truths can transform our lives.

    It enables us to understand the structure and evolution of planetary systems, stars, galaxies, interstellar gas, and the cosmos as a whole.In this Very Short Introduction, the leading astrophysicist James Binney shows how the field of astrophysics has expanded rapidly in the past century, with vast quantities of data gathered by telescopes exploiting all parts of the electromagnetic spectrum, combined with the rapid advance of computing power, which has allowed increasingly effective mathematical modelling. He illustrates how the application of fundamental principles of physics - the consideration of energy and mass, and momentum - and the two pillars of relativity and quantum mechanics, has provided insights into phenomena ranging from rapidly spinning millisecond pulsars to the collision of giant spiral galaxies. This is a clear, rigorous introduction to astrophysics for those keen to cut their teeth on a conceptual treatment involving some mathematics.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable

    He questions the idea that there is a world that encompasses everything like a container life, the universe, and everything else. This all-inclusive being does not exist and cannot exist. For the world itself is not found in the world. And even when we think about the world, the world about which we think is obviously not identical with the world in which we think. For, as we are thinking about the world, this is only a very small event in the world. Besides this, there are still innumerable other objects and events: rain showers, toothaches and the World Cup. Drawing on the recent history of philosophy, Gabriel asserts that the world cannot exist at all, because it is not found in the world. Yet with the exception of the world, everything else exists; even unicorns on the far side of the moon wearing police uniforms. Revelling in witty thought experiments, word play, and the courage of provocation, Markus Gabriel demonstrates the necessity of a questioning mind and the role that humour can play in coming to terms with the abyss of human existence.

    He's certainly been thinking about it lately. May, a freshly minted astrophysics Ph.D., joins forces with legendary astronomer Patrick Moore and astrophysicist Chris Lintott in Bang! to consider the history of the universe from the Big Bang to Heat Death.Space, time, and matter were birthed 13.7 billion years ago and will continue on longer than we are able to comprehend. Infinitesimally small at first, the Universe is immense and ever expanding. Bang! explains how it all started, takes you on a tour of what is known about the evolution of the Universe, and posits how the end of time will come about.This fascinating book includes photographs, short biographies of key figures, an at-a-glance timeline, a glossary of terms, and suggested resources for further exploration.Based on the work of history’s most brilliant scientific minds, this amazing story features clear, straightforward discussions of the most perplexing and compelling aspects of existence—from the formation of stars, planets, and other galactic bodies to black holes, quasars, anti-matter, and dark matter to the emergence of life and the possibility that it could exist elsewhere.Pick up a copy of Bang! It will, it will rock you.

    I’m Tim. I’m a single cell in society’s body. U.S. society, to be specific.So let me explain why we’re here.As a writer and a generally thinky person, I’ve spent a lot of my life thinking about the society I live in, and societies in general. I’ve always imagined society as a kind of giant human—a living organism like each of us, only much bigger.When you’re a single cell in the body of a giant, it’s hard to understand what the giant’s doing, or why it is the way it is, because you can’t really zoom out and look at the whole thing all at once. But we do our best.The thing is, when I’ve recently tried to imagine what society might look like, I haven’t really been picturing this:Giant stick figure: "I am grown up."Based on what I see around me, in person and online, it seems like my society is actually more like this:Giant stick figure throwing a giant tantrum because their chocolate ice cream fell on the ground.Individual humans grow older as they age—but it kind of seems like the giant human I live in has been getting more childish each year that goes by.So I decided to write a blog post about this. But then something else happened.When I told people I was planning to write a post about society, and the way people are acting, and the way the media is acting, and the way the government is acting, and the way everyone else is acting, people kept saying the same thing to me.Don’t do it. Don’t touch it. Write about something else. Anything else. It’s just not worth it.They were right. With so many non-controversial topics to write about, why take on something so loaded and risk alienating a ton of readers? I listened to people’s warnings, and I thought about moving on to something else, but then I was like, “Wait what? I live inside a giant and the giant is having a six-year-old meltdown in the grocery store candy section and that’s a not-okay thing for me to talk about?”It hit me that what I really needed to write about was that—about why it’s perilous to write about society."

    It possesses a precise predictive value as well as a deep interpretation of the movement of life, unfolding the secrets of karma and destiny. Astrology of the Seers, first published in 1990, is regarded as one of the classic modern books on Vedic astrology, covering all the main aspects of its philosophy, background and practice. The present edition has been thoroughly revised and updated.

    Yet in the late twentieth century truth became suddenly rather unfashionable. The precedence given to assorted political and ideological agendas, along with the rise of relativism, postmodernism and pseudoscience in academia, led to a decline both of truth as a serious subject, and an intellectual tradition that began with the Enlightenment.Why Truth Matters is a timely, incisive and entertaining look at how and why modern thought and culture lost sight of the importance of truth. It is also an eloquent and inspiring argument for restoring truth to its rightful place. Jeremy Stangroom and Ophelia Benson, editors of the successful butterfliesandwheels website—itself established to "fight fashionable nonsense"—identify and debunk such senselessness, and the spurious claims made for it, in all its forms. Their account ranges over religious fundamentalism, Holocaust denial, the challenges of postmodernism and deconstruction, the wilful misinterpretation of evolutionary biology, identity politics and wishful thinking.Why Truth Matters is both a rallying cry for the Enlightenment vision and an essential read for anyone who's ever been bored, frustrated, bewildered or plain enraged by the worst excesses of the fashionable intelligentsia.

    There are many contradictory beliefs about God that claim to be the truth. But since truth never contradicts itself, who really has the truth? Utilizing objective evidence like a detective does in an investigation, the facts point to the one belief that can be proven beyond a reasonable doubt. One truth that applies to everyone if they believe it or not. Follow the evidence and see for yourself.Setting feelings and what others believe aside for a moment learn why objective evidence is the best way to find truth in any investigation, including the truth about God. See for yourself exactly why Christianity is the most reasonable belief available based on the facts and why it applies to everyone, everywhere even if they do not believe it. Learn the two things we all encounter daily that the Bible states is absolute proof of God's existence and leave every person without excuse, even those who have never read the Bible. Learn why trying to be a good person is not good enough.Weigh the objective evidence for yourself and make a reasonable decision about God and then pass the evidence on to others so they can discover the truth. Everyone deserves the opportunity to examine the evidence for themselves.Perfect for the seeker and the believer who want to eliminate doubts and have a reasonable assurance that their faith is actually placed in the truth.If you are a believer you have an obligation to share the truth. Let this book show your friends and family the sound foundation your belief rests upon. It's not about religion, it's about truth.

    In What If the Earth Had Two Moons, Neil Comins leads us on a fascinating ten-world journey as we explore what our planet would be like under alternative astronomical conditions. In each case, the Earth would be different, often in surprising ways. The title chapter, for example, gives us a second moon orbiting closer to Earth than the one we have now. The night sky is a lot brighter, but that won't last forever. Eventually the moons collide, with one extra-massive moon emerging after a period during which Earth sports a Saturn-like ring. This and nine and other speculative essays provide us with insights into the Earth as it exists today, while shedding new light on the burgeoning search for life on planets orbiting other stars. Appealing to adult and young adult readers alike, this book follows on the author's previous bestseller, What If the Moon Didn't Exist?, with completely new scenarios backed by the latest astronomical research.

    But Shep Doeleman and a global coalition of scientists are on the cusp of doing just that.With exclusive access to the team, journalist Seth Fletcher spent five years following Shep and an extraordinary cast of characters as they assembled the Event Horizon Telescope, a virtual radio observatory the size of the Earth. He witnessed their struggles, setbacks, and breakthroughs, and along the way, he explored the latest thinking on the most profound questions about black holes. Do they represent a limit to our ability to understand reality? Or will they reveal the clues that lead to the long-sought Theory of Everything?Fletcher transforms astrophysics into something exciting, accessible, and immediate, taking us on an incredible adventure to better understand the complexity of our galaxy, the boundaries of human perception and knowledge, and how the messy human endeavor of science really works.Weaving a compelling narrative account of human ingenuity with excursions into cutting-edge science, Einstein’s Shadow is a tale of great minds on a mission to change the way we understand our universe—and our place in it.

    . . But, ironically, so was my later journey to God.' - Lee StrobelDuring his academic years, Lee Strobel became convinced that God was outmoded, a belief that colored his ensuing career as an award-winning journalist at the Chicago Tribune. Science had made the idea of a Creator irrelevant - or so Strobel thought. But today science is pointing in a different direction. In recent years, a diverse and impressive body of research has increasingly supported the conclusion that the universe was intelligently designed. At the same time, Darwinism has faltered in the face of concrete facts and hard reason.Has science discovered God? At the very least, it's giving faith an immense boost as new findings emerge about the incredible complexity of our universe. Join Strobel as he re-examines the theories that once led him away from God. Through his compelling and highly readable account, you'll encounter the mind-stretching discoveries from cosmology, cellular biology, DNA research, astronomy, physics, and human consciousness that present astonishing evidence in The Case for a Creator.
