Barely 50 years ago a computer was a gargantuan, vastly expensive thing that only a handful of scientists had ever seen. The world's brightest engineers were stymied in their quest to make these machines small and affordable until the solution finally came from two ingenious young Americans. Jack Kilby and Robert Noyce hit upon the stunning discovery that would make possible the silicon microchip, a work that would ultimately earn Kilby the Nobel Prize for physics in 2000.

Sparked by a controversial debate in February 2014, Bill Nye has set off on an energetic campaign to spread awareness of evolution and the powerful way it shapes our lives. In Undeniable: Evolution and the Science of Creation, he explains why race does not really exist; evaluates the true promise and peril of genetically modified food; reveals how new species are born, in a dog kennel and in a London subway; takes a stroll through 4.5 billion years of time; and explores the new search for alien life, including aliens right here on Earth.

Journalist Dom Phillips traveled deep into the Amazon rainforest searching for solutions to the problem of deforestation, a threat to the local ecosystem, native tribes, and the global climate. When he was murdered in the Javari Valley by a group of environmental criminals, a cohort of journalists and activists took up his work to finish his book and share his important message.

The problem of agriculture is as old as civilization. Throughout history, great societies that abused their land withered into poverty or disappeared entirely. Now we risk repeating this ancient story on a global scale due to ongoing soil degradation, a changing climate, and a rising population. But there is reason for hope. David R. Montgomery introduces us to farmers around the world at the heart of a brewing soil health revolution that could bring humanity's ailing soil back to life remarkably fast.

Throughout history, scientists have come up with theories and ideas that just don't seem to make sense. These we call paradoxes. The paradoxes Al-Khalili offers are drawn chiefly from physics and astronomy and represent those that have stumped some of the finest minds. With elegant explanations that bring the listener inside the mind of those who've developed them, Al-Khalili helps us to see that, in fact, paradoxes can be solved if seen from the right angle.

Nearly everyone is familiar with holograms - three-dimensional images projected into space with the aid of a laser. Two of the world's most eminent thinkers believe that the universe itself may be a giant hologram, quite literally a kind of image or construct created, at least in part, by the human mind. University of London physicist David Bohm, one of the world's most respected quantum physicists, and Stanford neurophysiologist Karl Pribram, an architect of our modern understanding of the brain, have developed a remarkable new way of looking at the universe.

Stepping effortlessly from myth to cutting-edge science, Mutants gives a brilliant narrative account of our genetic code and the captivating people whose bodies have revealed it - a French convent girl who found herself changing sex at puberty; children who, echoing Homer's Cyclops, are born with a single eye in the middle of their foreheads; a village of long-lived Croatian dwarves; one family, whose bodies were entirely covered with hair, was kept at the Burmese royal court for four generations and gave Darwin one of his keenest insights into heredity.

One grey dismal day, Janine Marsh was on a trip to northern France to pick up some cheap wine. She returned to England a few hours later having put in an offer on a rundown old barn in the rural Seven Valleys area of Pas de Calais. This was not something she'd expected or planned for. Janine eventually gave up her job in London to move with her husband to live the good life in France. Or so she hoped. While getting to grips with the locals and la vie Française, and renovating her dilapidated new house, a building lacking the comforts of mains drainage, heating, or proper rooms.

V. S. Ramachandran is at the forefront of his field - so much so that Richard Dawkins dubbed him the "Marco Polo of neuroscience". Now, in a major new work, Ramachandran sets his sights on the mystery of human uniqueness. Taking us to the frontiers of neurology, he reveals what baffling and extreme case studies can teach us about normal brain function and how it evolved.

In Waves in an Impossible Sea, physicist Matt Strassler tells a startling tale of elementary particles, human experience, and empty space. He begins with a simple mystery of motion. When we drive at highway speeds with the windows down, the wind beats against our faces. Yet our planet hurtles through the cosmos at 150 miles per second, and we feel nothing of it. How can our voyage be so tranquil when, as Einstein discovered, matter warps space, and space deflects matter? The answer, Strassler reveals, is that empty space is a sea, albeit a paradoxically strange one.

On July 23, 1999, the Chandra X-Ray Observatory, the most powerful X-ray telescope ever built, was launched aboard the space shuttle Columbia. Since then, Chandra has given us a view of the universe that is largely hidden from telescopes sensitive only to visible light. In Chandra's Cosmos, Wallace H. Tucker uses a series of short, connected stories to describe the telescope's exploration of the hot, high-energy face of the universe.

In this collection of lectures that Richard Feynman originally gave in 1963, unpublished during his lifetime, the Nobel Prize-winning physicist discusses several of the ultimate questions of science. What is the nature of the tension between science and religious faith? Why does uncertainty play such a crucial role in the scientific imagination? Is this really a scientific age?

Starting in November 2013 in a forest in Rwanda, where a modest spring spouts a trickle of clear, cold water, Levison Wood set forth on foot, aiming to become the first person to walk the entire length of the Nile. He followed the river for nine months, over 4,000 miles, through six nations - Rwanda, Tanzania, Uganda, South Sudan, the Republic of Sudan, and Egypt - to the Mediterranean coast.
