The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells - assemblies of otherwise "dead" molecules - come to life, and together constitute a living being? In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.

Bridging the gap between the world of science and the realm of the spiritual, Wallace, a pioneer of modern consciousness research, offers a practical and revolutionary method for exploring the mind that combines the keenest insights of contemporary physics and philosophers with the time-honored meditative traditions of Buddhism.

Drawing on troves of declassified files, including records released by the government for the first time through the author's efforts, Restricted Data traces the complex evolution of the US nuclear secrecy regime from the first whisper of the atomic bomb through the mounting tensions of the Cold War and into the early 21st century. A compelling history of powerful ideas at war, it tells a story that feels distinctly American: rich, sprawling, and built on the conflict between high-minded idealism and ugly, fearful power.

How do you introduce something so groundbreaking and new, yet also so ancient that it deals with the very first moments of Creation? Most people know about the 22 letters of the Hebrew Alphabet, and many have studied a bit of quantum theory. However, one thing has been missing that has to do with the divine language of Eden and the reset back to Eden and beyond.

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.

The brain is made up of 85 billion neurons, which are connected by over 100 trillion synapses. For over a century, a diverse array of researchers have been trying to find a language that can be used to capture the essence of what these neurons do and how they communicate - and how those communications create thoughts, perceptions, and actions. The language they were looking for was mathematics, and we would not be able to understand the brain as we do today without it.

'A gripping exploration of one of the most fundamental, but also perplexing aspects of existence.' PROF. LEWIS DARTNELL, author of Origins 'Such an enjoyable read...full of delightful nuggets that you will want to impress your friends and family with.' PROF. JIM AL-KHALILI, NYT bestselling...

What is the nature of the material world? How does it work? What is the universe and how was it formed? What is life? Where do we come from and how did we evolve? How and why do we think? What does it mean to be human? How do we know? There are many different versions of our creation story. This book tells the version according to modern science. It is a unique account, starting at the Big Bang and travelling right up to the emergence of humans as conscious intelligent beings, 13.8 billion years later.

Werner Heisenberg's "uncertainty principle" challenged centuries of scientific understanding, placed him in direct opposition to Albert Einstein, and put Niels Bohr in the middle of one of the most heated debates in scientific history. Heisenberg's theorem stated that there were physical limits to what we could know about sub-atomic particles; this "uncertainty" would have shocking implications.

In the vein of Randall Munroe's What If? meets Brian Green's Elegant Universe, a senior writer from Space.com leads readers on a wild ride of exploration into the final frontier, investigating what's really "out there." We've all asked ourselves the question. It's impossible to look up at the...

Our intuition about how things should behave is usually right in the everyday world. We see the baseball soar in the air, arc, drop, and lie stationary on the ground. Through data gathered by our senses and basic knowledge of the laws of classical mechanics, the motion of a ball makes perfect sense. But enter the world of the tiniest particles on earth—the motion of electrons, the shapes of molecules—and everything we think we know about the world radically changes.

In the course of our enduring quest for knowledge about ourselves and our universe, we haven't found answers to one of our most fundamental questions: Does life exist anywhere else in the universe? Ten years and billions of dollars in the making, the Mars rover Curiosity is poised toanswer this all-important question.

Scientists tell us that ninety-six percent of the universe is unexplained dark matter and dark energy. Also, they admit that no unifying “theory of everything” exists in physics. This shaky foundation is the basis of modern thinking about the cosmos and Earth’s place in it. Something big seems to be missing. Thus, we’re left with no choice but to question the “consensus” cosmological model. Are we really flying through space on a spinning ball within an expanding universe, while free-falling around the Sun—all as a consequence of a “Big Bang” that supposedly occurred 13.8 billion years ago?

Our understanding of nature's deepest reality has changed radically, but almost without our noticing, over the past 25 years. Transcending the clash of older ideas about matter and space, acclaimed physicist Frank Wilczek explains a remarkable new discovery: matter is built from almost weightless units, and pure energy is the ultimate source of mass. He calls it "The Lightness of Being." Space is no mere container, empty and passive. It is a dynamic Grid, modern ether, and its spontaneous activity creates and destroys particles.

A hopeful and controversial view of the universe and ourselves based on the principles of quantum physics, offering a way of making our lives and the world better, with a foreword by Deepak Chopra In Infinite Potential, physical chemist Lothar Schäfer presents a stunning view of the...

This audiobook contains a broad overview of time travel in science fiction, along with a detailed examination of the philosophical implications of time travel. The emphasis of this book is now on the philosophical and on science fiction, rather than on physics, as in the author’s earlier books on the subject. In that spirit there are, for example, no tech notes filled with algebra, integrals, and differential equations, as there are in the first and second editions of Time Machines.

In this Very Short Introduction, William Lowrie describes the internal and external processes that affect the planet, as well as the principles and methods of geophysics used to investigate them. From analyses of Earth's deepest interior to measurements made from Earth-orbiting satellites, Lowrie shows how geophysical exploration is vitally important in the search for mineral resources and emphasizes our need to understand the history of our planet and the processes that govern its continuing evolution.

In a world defined by rapid change and mounting uncertainty, it's easy to feel unmoored or unsure of how to move forward. This book offers scientific and experiential insights to navigate such times through the interconnected domains of mind, body, and world. It moves beyond a collection of facts to uncover the deeper foundations of coherence and understanding.

Humanity's first reusable spacecraft and the most complex machine ever built, NASA's space shuttle debuted with great promise and as a dependable source of wonder and national pride. But with the Challenger catastrophe in 1986, the whole space shuttle program came into question, as did NASA itself, so long an institution that was seemingly above reproach. Wheels Stop tells the stirring story of how, after the Challenger disaster, the space shuttle not only recovered but went on to perform its greatest missions.

These are the extraordinary realities of the NHS frontline. From the historic junior doctor strikes to the 'humanitarian crisis' declared by the Red Cross, the overstretched health service is on the precipice. This is a powerful polemic on its systematic degradation, and a letter of optimism to that same health service and those who support it. It captures with tenderness, a new doctor's experiences of an NHS at breaking point.
