A boy rides a bicycle down a dusty road. But in his mind, he envisions himself traveling at a speed beyond imagining, on a beam of light. This brilliant mind will one day offer up some of the most revolutionary ideas ever conceived. From a boy endlessly fascinated by the wonders around him, Albert Einstein ultimately grows into a man of genius recognized the world over for profoundly illuminating our understanding of the universe. Jennifer Berne and Vladimir Radunsky invite the reader to travel along with Einstein on a journey full of curiosity, laughter, and scientific discovery. Parents and children alike will appreciate this moving story of the powerful difference imagination can make in any life.

This book pieces together the jigsaw puzzle of Einstein’s journey to discovering the special theory of relativity. Between 1902 and 1905, Einstein sat in the Patent Office and may have made calculations on old pieces of paper that were once patent drafts. One can imagine Einstein trying to hide from his boss, writing notes on small sheets of paper, and, according to reports, seeing to it that the small sheets of paper on which he was writing would vanish into his desk-drawer as soon as he heard footsteps approaching his door. He probably discarded many pieces of papers and calculations and flung them in the waste paper basket in the Patent Office. The end result was that Einstein published nothing regarding the special theory of relativity prior to 1905. For many years before 1905, he had been intensely concerned with the topic; in fact, he was busily working on the problem for seven or eight years prior to 1905. Unfortunately, there are no surviving notebooks and manuscripts, no notes and papers or other primary sources from this critical period to provide any information about the crucial steps that led Einstein to his great discovery. In May 1905, Henri Poincaré sent three letters to Hendrik Lorentz at the same time that Einstein wrote his famous May 1905 letter to Conrad Habicht, promising him four works, of which the fourth one, Relativity, was a rough draft at that point. In the May 1905 letters to Lorentz, Poincaré presented the basic equations of his 1905 “Dynamics of the Electron”, meaning that, at this point, Poincaré and Einstein both had drafts of papers relating to the principle of relativity. The book discusses Einstein’s and Poincaré’s creativity and the process by which their ideas developed. The book also explores the misunderstandings and paradoxes apparent in the theory of relativity, and unravels the subtleties and creativity of Einstein.

A Voyage in Consciousness is an adventure in self-exploration, revealing a path to peace that emerges from the simple act of attending to one's own ordinary experience. All human beings are adventurers. We are all exploring what it is to be and know, to live and die, to sleep and awaken. Each of us has his or her own path to follow. Every one of us is destined to realize a peculiar enlightenment and make his or her unique contribution to the brilliance of creation. Within the spectrum of human experience great treasures wait to be discovered. The work of only a few explorers is not enough to unearth them. These treasures are vast, but undiscoverable without the deepest appreciation of our joy. As more of us become involved in this exploration, the greater our discoveries shall be. The greater the peace of humankind, the greater the ecstasy of all living beings. A Voyage in Consciousness is both an invitation and a unique set of tools that facilitate experiential exploration. The information presented comes from the author's own discoveries gleaned from more than 20 years of experiential research. A Voyage in Consciousness doesn't just tell stories about experiential exploration, it is an adventure which each reader navigates in his or her own way. The book includes detailed, guided exercises specifically designed to facilitate the reader's own journey.

A sweeping account of the century of experimentation that confirmed Einstein’s general theory of relativity, bringing to life the science and scientists at the origins of relativity, the development of radio telescopes, the discovery of black holes and quasars, and the still unresolved place of gravity in quantum theory. Albert Einstein did nothing of note on May 29, 1919, yet that is when he became immortal. On that day, astronomer Arthur Eddington and his team observed a solar eclipse and found something extraordinary: gravity bends light, just as Einstein predicted. The finding confirmed the theory of general relativity, fundamentally changing our understanding of space and time. A century later, another group of astronomers is performing a similar experiment on a much larger scale. The Event Horizon Telescope, a globe-spanning array of radio dishes, is examining space surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way. As Ron Cowen recounts, the foremost goal of the experiment is to determine whether Einstein was right on the details. Gravity lies at the heart of what we don’t know about quantum mechanics, but tantalizing possibilities for deeper insight are offered by black holes. By observing starlight wrapping around Sagittarius A*, the telescope will not only provide the first direct view of an event horizon—a black hole’s point of no return—but will also enable scientists to test Einstein’s theory under the most extreme conditions. Gravity’s Century shows how we got from the pivotal observations of the 1919 eclipse to the Event Horizon Telescope, and what is at stake today. Breaking down the physics in clear and approachable language, Cowen makes vivid how the quest to understand gravity is really the quest to comprehend the universe.

Evo-illusion takes a completely objective and science-based look at evolution. Blume details his pathway from his childhood of being raised very much a religious creationist, to his early fascination with science, and then to his becoming beguiled by evolution and Charles Darwin in his first paleontology class in college. Blume then tells of his surprising and enlightening reversal. Evo-illusion tells a fascinating story of biology, astronomy, physics, particle physics, and other sciences that would certainly interest any person who reads it, no matter what their position is on evolution. It takes the reader from the beginning of the universe to the first living cells on Earth, to the first multicellular organism, and then to the formation of modern organisms. Blume uniquely utilizes thought experiments that the readers can easily do, which allow them to figure what may and may not have happened during the early steps on the pathway to the formation of multicellular organisms.
