From Here to Infinity: A Vision for the Future of Science
Martin J. Rees - 2011
To shape debates over health care, energy policy, space travel, and other vital issues, ordinary citizens must engage directly with research rather than relying on pundits’ and politicians’ interpretations. Otherwise, fringe opinions that have been discredited in the scientific community can take hold in the public imagination. At the same time, scientists must understand their roles as communicators and ambassadors as well as researchers.Rees not only diagnoses this central problem but also explains how scientists and the general public can deploy a global, long-term perspective to address the new challenges we face. In the process, he reveals critical shortcomings in our current system—for example, the tendency to be overly anxious about minor hazards while underrating the risk of potential catastrophes. Offering a strikingly clear portrait of the future of science, Rees tackles such diverse topics as the human brain, the possibility that humans will colonize other planets, and the existence of extraterrestrial life in order to distinguish between what scientists can hope to discover and what will always lie beyond our grasp.A fresh perspective on science’s significance and potential, From Here to Infinity will inspire and enlighten.
On Cosmic Religion and Other Opinions and Aphorisms
Albert Einstein - 1931
In these essays, Einstein views science as the basis for a "cosmic" religion, embraced by scientists, theologians, and all who share a sense of wonder in the rationality and beauty of the universe. In the course of his career, Einstein wrote more than 300 scientific and 150 nonscientific publications. These essays date from the 1930s and 40s. In direct, everyday language the author develops a coherent view that transcends both the antiquated religion of fear and the modern religion of ethics. His concept of cosmic religion combines science and religion, with science forming the basis for a more enlightened religion. In these essays and aphorisms, Einstein also reflects on pacifism, disarmament, and Zionism. In addition to a brief biography of the author, this volume includes a warm appreciation by George Bernard Shaw.
Einstein, Picasso: Space, Time, and the Beauty That Causes Havoc
Arthur I. Miller - 2001
This fascinating parallel biography of Albert Einstein and Pablo Picasso as young men examines their greatest creations -- Picasso's Les Demoiselles d'Avignon and Einstein's special theory of relativity. Miller shows how these breakthroughs arose not only from within their respective fields but from larger currents in the intellectual culture of the times. Ultimately, Miller shows how Einstein and Picasso, in a deep and important sense, were both working on the same problem.
The Gods Never Left Us: The Long Awaited Sequel to the Worldwide Best-seller Chariots of the Gods
Erich von Däniken - 2017
In an era of the military space race, Erich von Däniken boldly proclaimed that Earth had been visited by more advanced beings early in our history. But prescientific man had no concept of space ships, so he called their vehicles “chariots,” and those driving the chariots became “gods.”
Over the next five decades, von Däniken’s more than 40 books built an ever-stronger case for Earth being visited by extraterrestrial visitors. And Chariots became an international best seller, with 30 million copies sold in more than two dozen languages. Also during that time, the case for ET visitations millennia ago was being reexamined by contemporary UFO researchers, who found evidence of modern visitations. And von Däniken expanded his perspective to encompass the present.
Now, he presents his long-awaited sequel to Chariots of the Gods, proclaiming that the gods never left us with all-new material to show that ancient aliens are still with us.
The Gods Never Left Us contends that recent advancements in biotechnology, astrophysics, engineering, and artificial intelligence not only give us a fresh perspective on his ancient astronaut theory but actually validates it. We are—as a race—embarking on the exact same trajectory of our own interplanetary colonization, just as von Däniken suggested Earth itself was colonized.
ETs are definitely at work today. And that affects all of us.
Why do they do what they do? What could an extraterrestrial species possibly gain from observing us in the same way we look at ants?
What have these strangers wanted for the past thousands of years?
Can’t they leave us alone?
And what makes it so difficult for us to acknowledge the existence of these extraterrestrials?
That is what this book deals with.
"Erich's newest book is a fascination journey from the ancient past into the present with a plethora of scientific evidence and documented research. As always, he ads his own "to the point" take on it all. Readers may also like that his newest work moves in a slightly different direction from his past books. A thoroughly enlightening and enjoyable Read." —Bruce Cunningham, Director, Ancient Mysteries International LLC & Publisher of Advanced Archaeology Review magazine

Phyllis Galde - 2017
Over the next ten years the “Strange” books sold over 6,000,000 copies worldwide. Strange True Encounters & Unearthly Experiences is the first new book in the series in over three decades, and features: Robert M. Schoch, Ph.D. in Geology and Geophysics at Yale University on discoveries at Anatolia‘s Gobekli Tepe suggesting civilization is far older than previously believed. Gregory Sams on unfolding evidence that stars may be conscious. Janet Brennan on Europe’s mysterious Black Madonna statues. Martin Cadin, ex-member Federal Aviation Administration, on his personal experiments using telekinesis. Michio Kaku, Professor of Theoretical Physics at the City University of New York, on our ten-dimensional universe and paranormal phenomenon. Journalist Chris Friar on 19th century UFO sightings proving they are not a modern phenomenon. Actor Anthony Quinn on the “profound mystical experience” in the Sinai Desert that changed his life. Plus over a dozen other accounts, investigation and in-depth reports on the Ouija board, remote viewing, poltergeists, Kansas’ sacred sites, the U.S. warship that was saved by an angel, and much more. We believe this brand new entry in the “Strange” series – is in every way the equal of its predecessors. And will prove every bit as entertaining and enlightening as the earlier books did. (Asked where he got the ideas for his stories, Steven King credited FATE. “My mother used to read me FATE Magazine, which was about the paranormal, flying saucers…all that stuff. I was fascinated.”) Here is what Amazon readers have to say about classic reprints from FATE: “A book worth reading. I look forward to reading the other books in this series.” “FATE always comes through.” “Well written, short articles on a variety of paranormal events, many of which were unfamiliar to me. Interesting, unfamiliar and competently edited.” “Good stuff. Reminds us that stories like this have been happening for years. Not just a modern invention. Worth a read.” “Very good read. 5 stars.”
A Series of Fortunate Events: Chance and the Making of the Planet, Life, and You
Sean B. Carroll - 2020
Carroll at his very best.--Bill Bryson, author of The Body: A Guide for Occupants From acclaimed writer and biologist Sean B. Carroll, a rollicking, awe-inspiring story of the surprising power of chance in our lives and the worldWhy is the world the way it is? How did we get here? Does everything happen for a reason or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance. A Series of Fortunate Events tells the story of the awesome power of chance and how it is the surprising source of all the beauty and diversity in the living world.Like every other species, we humans are here by accident. But it is shocking just how many things--any of which might never have occurred--had to happen in certain ways for any of us to exist. From an extremely improbable asteroid impact, to the wild gyrations of the Ice Age, to invisible accidents in our parents' gonads, we are all here through an astonishing series of fortunate events. And chance continues to reign every day over the razor-thin line between our life and death.This is a relatively small book about a really big idea. It is also a spirited tale. Drawing inspiration from Monty Python, Kurt Vonnegut, and other great thinkers, and crafted by one of today's most accomplished science storytellers, A Series of Fortunate Events is an irresistibly entertaining and thought-provoking account of one of the most important but least appreciated facts of life.
