The final book from Professor Stephen Hawking, the best-selling author of A Brief History of Time and arguably the most famous scientist of our age, Brief Answers to the Big Questions is a profound, accessible and timely reflection on the biggest questions in science. Professor Hawking was a brilliant theoretical physicist, an influential author and thinker and a great popular communicator. Throughout his career he was asked questions by business leaders, politicians, entrepreneurs, academics and the general public on a broad range of subjects, from the origins of the universe to the future of the planet.

Hawking takes us on a fascinating journey through the telescopic lens of modern physics to gain a new glimpse of the universe--the nature of black holes, the space-time continuum, and new information about the origin of the universe. He uses this scientific basis to come up with a "unified theory of everything" that the author claims will be "the ultimate triumph of human reason."

Seeking to uncover the holy grail of science, the elusive Theory of Everything that lies at the heart of the cosmos, Professor Stephen Hawking takes us to the cutting edge of theoretical physics. In a realm where truth is often stranger than fiction, he explains in layman's terms the principles that control our universe.

In this groundbreaking new work, Professor Hawking and renowned science writer Leonard Mlodinow have drawn on 40 years of Hawking's own research and a recent series of extraordinary astronomical observations and theoretical breakthroughs to reveal an original and controversial theory.

What is the nature of space and time? How do we fit within the universe? How does the universe fit within us? There's no better guide through these mind-expanding questions than acclaimed astrophysicist and best-selling author Neil deGrasse Tyson. But today, few of us have time to contemplate the cosmos. So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in digestible chapters consumable anytime and anywhere in your busy day.

Professor Brian Cox uncovers some of the most extraordinary natural events on Earth and in the universe and beyond. From the immensity of the universe and the roundness of Earth to the form of every single snowflake, the forces of nature shape everything we see. Pushed to extremes, the results are astonishing. In seeking to understand the everyday world, the colours, structure, behaviour and history of our home, we develop the knowledge and techniques necessary to step beyond the everyday.

Jupiter: The Ruthless One. Mars: The Doomed One. Sun: The Fiery One. Saturn: The Beautiful One. Pluto: The Mysterious One. We’re living through an extraordinary time of exploration. A fleet of space probes are continually beaming data from their sensors back to Earth. Hidden in this stream of code are startling new discoveries about the worlds we share with the Sun. We will piece together these remarkable and often surprising findings to tell the greatest science story of them all - the life and times of the Solar System.

Stephen Hawking's worldwide best seller, A Brief History of Time, has been a landmark volume in scientific writing. Its author's engaging voice is one reason, and the compelling subjects he addresses is another: the nature of space and time, the role of God in creation, and the history and future of the universe.

In a rare blend of scientific insight and writing as elegant as the theories it explains, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of 11 dimensions where the fabric of space tears and repairs itself, and all matter-from the smallest quarks to the most gargantuan supernovas-is generated by the vibrations of microscopically tiny loops of energy.

Human life is a staggeringly strange thing. On the surface of a ball of rock falling around a nuclear fireball in the blackness of a vacuum, the laws of nature conspired to create a naked ape that can look up at the stars and wonder where it came from. What is a human being? Objectively, nothing of consequence. Particles of dust in an infinite arena, present for an instant in eternity.

In one of the most exciting and accessible explanations of The Theory of Relativity in recent years, Professors Brian Cox and Jeff Forshaw go on a journey to the frontier of 21st century science to consider the real meaning behind the iconic sequence of symbols that make up Einstein's most famous equation, exploring the principles of physics through everyday life.

Cosmos is one of the best-selling science books of all time. In clear-eyed prose, Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space.

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?

Perhaps the most influential science book ever written, On the Origin of Species has continued to fascinate for more than a century after its initial publication. Its controversial theory that populations evolve and adapt through a process known as natural selection led to heated scientific, philosophical, and religious debate, revolutionizing every discipline in its wake. With its clear, concise, and surprisingly enjoyable prose, On the Origin of Species is both captivating and edifying.

Why can some birds sleep with only half of their brain? What really happens during REM sleep? Why do our sleep patterns change across a lifetime? Sleep is one of the most important but least understood aspects of our life, health and longevity. Until very recently, science had no answer to the question of why we sleep or what good it serves or why we suffer such devastating health consequences when it is absent. In this book, neuroscientist and sleep expert Matthew Walker charts 20 years of cutting-edge research.
