The most important things in life are our health and happiness. Yet most of us are neither healthy nor happy. We have been led to believe that if we think ahead and make the right choices, we can manifest our dreams. Yet despite our best efforts, we still have more disease and discontent than ever before. Is it possible that our essential ideas about life are flawed? We are all aware of the impact of sunlight on a plant's growth and development. But few of us realize that a plant actually "sees" where light is emanating from and positions itself to be in optimal alignment with it.

With all the passion, curiosity, and precise yet lyrical prose that have marked his previous books, Alan Lightman here explores the emotional and philosophical questions raised by discoveries in science, focusing most intently on the human condition and the needs of humankind. He looks at the difficult dialogue between science and religion, the conflict between our human desire for permanence and the impermanence of nature, the possibility that our universe is simply an accident, the manner in which modern technology has separated us from direct experience of the world, and our resistance to the view that our bodies and minds can be explained by scientific logic and laws.

In Three Roads to Quantum Gravity, Lee Smolin provides an accessible overview of the attempts to build a final "theory of everything." He explains in simple terms what scientists are talking about when they say the world is made from exotic entities such as loops, strings, and black holes and tells the fascinating stories behind these discoveries: the rivalries, epiphanies, and intrigues he witnessed firsthand.

Nikola Tesla was a major contributor to the electrical revolution that transformed daily life at the turn of the 20th century. His inventions, patents, and theoretical work formed the basis of modern AC electricity, and contributed to the development of radio and television. Like his competitor Thomas Edison, Tesla was one of America's first celebrity scientists, enjoying the company of New York high society and dazzling the likes of Mark Twain with his electrical demonstrations. An astute self-promoter and gifted showman, he cultivated a public image of the eccentric genius.

In Sticky, Laurie Winkless explores some of the ways that friction shapes both the manufactured and natural worlds and describes how our understanding of surface science has given us an ability to manipulate stickiness, down to the level of a single atom. But this apparent success doesn’t tell the whole story. Each time humanity has pushed the boundaries of science and engineering, we’ve discovered that friction still has a few surprises up its sleeve.

Join us on a journey through how we understand the universe, from its most basic particles and forces to planets, stars, and galaxies, and back through cosmic history to the birth of the cosmos. Conflicting notions about our place in the universe are defined, defended, and critiqued from scientific, philosophical, and religious viewpoints. The authors' engaging and witty style addresses what fine tuning might mean for the future of physics and the search for the ultimate laws of nature.

In Reconnecting to the Source he unpacks the science behind spiritual experience, investigating the ways in which we can access realms of experience beyond the everyday. It is in these moments, when our conscious minds are in contact or perhaps even overridden by our unconscious selves, that we can explore the depths of spiritual meaning. In addition to a foreword by Deepak Chopra, the book includes new, never before published contributions from a long list of well-known writers and public figures.

The discovery of quantum mechanics has paved the way to just about every important innovation in the last half century: it has led us to the technology that powers microwaves, iPhones, and self-driving cars and is about to trigger a computing revolution that will either spell the end of the human species or propel us to heights we've never imagined. But there's another reason that quantum mechanics is so important: it is really the only way we can understand ourselves and each other.

Carl Sagan, writer and scientist, returns from the frontier to tell us about how the world works. In his delightfully down-to-earth style, he explores and explains a mind-boggling future of intelligent robots, extraterrestrial life and its consequences, and other provocative, fascinating quandaries of the future that we want to see today.

Vic Tandy was a level-headed scientist, but there was no denying it: at this late hour in his lonely lab at Coventry University, he kept seeing a grey apparition out of the corner of his eye. Bathed in a cold sweat, his heart pounding in his chest, he questioned his own rational mind—could this really be a supernatural encounter? What on Earth could be sending such an eerie shudder through his body? Strange frequencies are all around us—in fact, there may be no limit to the marvellous power of vibration.

Electrical engineering is an engineering discipline concerned with the study, design and application of equipment, contrivances and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable vocation in the latter a moiety of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution and use.

You are reading the word now right now. But what does that mean? What makes the ephemeral moment "now" so special? Its enigmatic character has bedeviled philosophers, priests, and modern-day physicists from Augustine to Einstein and beyond. Einstein showed that the flow of time is affected by both velocity and gravity, yet he despaired at his failure to explain the meaning of now. Equally puzzling: Why does time flow? Some physicists have given up trying to understand and call the flow of time an illusion.

The Los Angeles Times headline screamed: Rocket Scientist Killed in Pasadena Explosion. The man known as Jack Parsons, a maverick rocketeer who helped transform a derided sci-fi plotline into actuality, was at first mourned as a scientific prodigy. But reporters soon uncovered a more shocking story: Parsons had been a devotee of the city’s occult scene.

The 20th century gave us two great theories of physics. The general theory of relativity describes the behavior of very large things, and quantum theory the behavior of very small things. In this landmark audiobook, John Gribbin - one of the best-known science writers of the past 30 years - presents his own version of the Holy Grail of physics, the search that has been going on for decades to find a unified "Theory of Everything" that combines these ideas into one mathematical package.

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 uses these questions to guide us toward modern science’s new and deeper understanding of the universe.

In Vaxxers, we hear directly from Professor Gilbert and her colleague, Dr Catherine Green, as they reveal the inside story of making the Oxford AstraZeneca vaccine and the cutting-edge science and sheer hard work behind it. This is their story of fighting a pandemic as ordinary people in extraordinary circumstances. Sarah and Cath share the heart-stopping moments in the eye of the storm, they separate fact from fiction, they explain how they made a safe vaccine in record time with the eyes of the world watching and they give us hope for the future.

Breathtaking, brilliant and passionate, these essays, journalism, lectures and letters make an unanswerable case for the wonder of scientific discovery and its power to stir the imagination; for the practical necessity of scientific endeavour to society; and for the importance of the scientific way of thinking – particularly in today’s ‘post-truth’ world.

From cyborgs, starships, UFOs, aliens and antimatter to telepathy, invisibility, psychokinesis and precognition, Michio Kaku's Physics of the Impossible is an exciting look at how science fiction could soon become science fact. Physics of the Impossible shows how our most far-fetched ideas today - from Star Trek's phasers and teleportation to time travel as envisioned by Back to the Future - are destined to become tomorrow's reality.

What if Isaac Newton had never lived? Robert Hooke and Edmond Halley, whose place in history has been overshadowed by the giant figure of Newton, were pioneering scientists within their own right and instrumental in establishing the Royal Society. Whilst Newton is widely regarded as one of the greatest scientists of all time and the father of the English scientific revolution, John and Mary Gribbin uncover the fascinating story of Robert Hooke and Edmond Halley....
