In The Quantum World, leading physicists and New Scientist take you on a journey through quantum theory, its mind-bending properties and the technologies transforming our world. Forget everything you thought you knew about reality. The world is a seriously bizarre place. Things can exist in two places at once and travel backwards and forwards in time. Waves and particles are one and the same, and objects change their behaviour according to whether they are being watched.

On September 14, 2015, after 50 years of searching, gravitational waves were detected for the first time, and astronomy changed forever. Up until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays, and the rest. But gravitational waves - ripples in the fabric of space and time - are unrelenting, passing through barriers that stop light dead.

Capra relates his personal journey of meeting and interacting with some of the leading contemporary thinkers and visionaries. What emerges is a wisdom-packed dialogue about new ways of thinking and being. From Krishnamurti's spiritual insight to Gregory Bateson's intellectual prowess, Capra weaves an intricate and informative web of influences on his own pioneering work of bridging science and spirit. For anyone interested in the future, this is a conversation not to be missed.

The discovery of the quantum - the idea, born in the early 1900s in a remote corner of physics, that energy comes in finite packets instead of infinitely divisible quantities - planted a rich set of metaphors in the popular imagination. Quantum imagery and language now bombard us like an endless stream of photons. Phrases such as multiverse, quantum leap, alternate universe, the uncertainty principle, and Schrödinger's cat get reinvented continually in cartoons and movies, coffee mugs and T-shirts, and fiction and philosophy.

Fear of Physics is a lively, irreverent, and informative look at everything from the physics of boiling water to cutting-edge research at the observable limits of the universe. Rich with anecdotes and accessible examples, it nimbly ranges over the tools and thought behind the world of modern physics, taking the mystery out of what is essentially a very human intellectual endeavor.

On April 10, 2019, award-winning astrophysicist Heino Falcke presented the first image ever captured of a black hole at an international press conference - a turning point in astronomy that Science magazine called the scientific breakthrough of the year. That photo was captured with the unthinkable commitment of an intercontinental team of astronomers who transformed the world into a global telescope. While this image achieved Falcke’s goal in making a black hole “visible” for the first time, he recognizes that the photo itself asks more questions for humanity than it answers.

The fundamental outlines of the physical world, from its tiniest particles to massive galaxy clusters, have been apparent for decades. Does this mean physicists are about to tie it all up into a neat package? Not at all. Just when you think you’re figuring it out, the universe begins to look its strangest, and this book illustrates how answers often lead to more questions and open up new paths to insight.

Our brains evolved to solve the survival problems of our Stone Age ancestors, so when faced with modern-day situations that are less extreme, they often encounter a mismatch. Our primitive brains put us on the wrong foot by responding to stimuli that - in prehistoric times - would have prompted behaviour that was beneficial. If you've ever felt an anxious fight-or-flight response to a presenting at a board meeting, equivalent to facing imminent death by sabre-toothed tiger, then you have experienced a mismatch.

In the 18th century, the British minister and mathematician Thomas Bayes devised a theorem that allowed him to assign probabilities to events that had never happened before. It languished in obscurity for centuries until computers came along and made it easy to crunch the numbers. Now, as the foundation of big data, Bayes's formula has become a linchpin of the digital economy. But here's where things get interesting: Bayes's theorem can also be used to lay odds on the existence of extraterrestrial intelligence, and on the biggest question of all: how long will humanity survive?

Expand Your Horizons: The Mandela Effect takes you on a journey into one of the most captivating mysteries of modern times—shared false memories that challenge our understanding of truth, memory, and reality itself. Why do millions of people vividly recall events that seem to have never happened? Is the Mandela Effect simply a glitch in how our minds reconstruct the past, or does it reveal something deeper—an interconnectedness between consciousness, alternate dimensions, and the very fabric of existence?

Developed by experienced professors and professionally narrated for easy listening, this course is a great way to explore the subject of college-level physics. The audio is focused and high-yield, covering the most important topics you might expect to learn in a typical undergraduate physics course. The material is accurate, up-to-date, and broken down into bite-size sections. There are quizzes and key takeaways following each section to review questions commonly tested and drive home key points.

If you were to present the feats of modern science to someone from the past, those feats would surely be considered magic. Theoretical physicist Felix Flicker proves that they are indeed magic—just familiar magic. The name for this magic is “condensed matter physics.” Most people haven’t heard of the field, yet more than a third of physicists identify as condensed matter researchers, making it the most active area in the subject—with good reason. Condensed matter is the solids, liquids, and gasses that surround us—and the more exotic matters—which dictate every aspect of our present existence.

Whether you believe it or not, the quantum world is real! Quantum physics discovers the behavior of energy and matter at the nuclear, atomic, molecular, and even smaller levels. This book will make such a complicated subject simple to comprehend. It avoids the complicated math and jumps right into all the implications, thought experiments, paradoxes, and concepts that make quantum physics so intriguing to people out there.

How do you get something out of nothing? It seems like an obvious question, one that drives everything from spiritual creation stories to our understanding of the big bang. Yet it leaves us with a sense that underneath everything lies emptiness and lack. We can phrase this question in a new way: How do we get something out of everything? In Leap to Wholeness, physics educator Sky Nelson-Isaacs explores the science of wholeness.

Although it is widely understood that energy and water are the world’s two most critical resources, their vital interconnections and vulnerabilities are less often recognized. This farsighted audiobook offers a new, holistic way of thinking about energy and water - a big picture approach that reveals the interdependence of the two resources, identifies the seriousness of the challenges, and lays out an optimistic approach with an array of solutions to ensure continuing sustainability.

Embark on a mind-expanding journey through the nature of reality itself! Is our universe one of many? Are we living in a simulation? What does quantum physics tell us about the fabric of reality? "The Beginner's Guide to Reality" breaks down these profound questions into three fascinating, accessible books that will forever change how you view existence.

"Cos'è il numero, che l'uomo lo può capire? E cos'è l'uomo, che può capire il numero?" A porsi queste domande fu nel 1960 il neurofisiologo Warren McCulloch, evidentemente insoddisfatto delle molte rigide e vuote definizioni che erano state sciorinate fino ad allora dai filosofi. In questo libro Piergiorgio Odifreddi affronta le due domande con un approccio più fluido e pratico: invece di provare inutilmente a dirci cos'è il numero in astratto, ci mostra utilmente una serie di numeri in concreto.

Quantum physics is an astounding (and mind-boggling) field of science, but can you actually use it to change your life? Absolutely yes, says Dr. Quantum. On A User's Guide to Your Universe, Dr. Quantum, who goes by day as mild-mannered physicist Dr. Fred Alan Wolf, teaches that anyone can understand quantum physics. What's more, it is the most useful, immediate, and relevant kind of science you can learn to profoundly affect your day-to-day life.
