Herriot continues the rich and rewarding day-to-day life of a small-town veterinarian, and we journey with him across the dales, meeting a whole new cast of unforgettable characters - humans, dogs, horses, lambs, parakeets - all of them drawn with the same infinite fascination, affection and insight that made James Herriot one of the most beloved authors of our time. And all the stories are warmly, evocatively told by the world-renowned "voice" of Dr. Herriot: Christopher Timothy.

The Earth teems with sights and textures, sounds and vibrations, smells and tastes, electric and magnetic fields. But every kind of animal, including humans, is enclosed within its own unique sensory bubble, perceiving but a tiny sliver of our immense world. In An Immense World, Ed Yong coaxes us beyond the confines of our own senses, allowing us to perceive the skeins of scent, waves of electromagnetism, and pulses of pressure that surround us.

Twenty years ago, Joel Salatin wrote You Can Farm, which has launched thousands of farm entrepreneurs around the world. With another 20 years of experience under his belt, bringing him to the half-century mark as a full-time farmer, he decided to build on that foundation with a sequel, a graduate-level curriculum. Everyone who reads (or listens to), and enjoys that previous work, will benefit from this additional information.

Jeff Tarrant was fascinated by the paranormal as a child but then his training as a neuropsychologist turned him into a hardcore skeptic. If something could not be reliably and consistently demonstrated in the laboratory, then it wasn’t real. These rigid ideas were gradually worn away as he repeatedly witnessed and experienced things that simply should not be possible—telekenesis, clairvoyance, telepathy, mediumship, energy healing, and more. This book follows his journey of studying, interviewing, and testing a wide variety of mediums, psychics, and healers.

This book is about pleasure. It’s also about pain. Most important, it’s about how to find the delicate balance between the two, and why now more than ever finding balance is essential. We’re living in a time of unprecedented access to high-reward, high-dopamine stimuli: drugs, food, news, gambling, shopping, gaming, texting, sexting, Facebooking, Instagramming, YouTubing, tweeting....

The science of emotion is in the midst of a revolution on par with the discovery of relativity in physics and natural selection in biology. Leading the charge is psychologist and neuroscientist Lisa Feldman Barrett, whose research overturns the long-standing belief that emotions are automatic, universal, and hardwired in different brain regions. Instead, Barrett shows, we construct each instance of emotion through a unique interplay of brain, body, and culture.

On May 1, 1915, with WWI entering its tenth month, a luxury ocean liner as richly appointed as an English country house sailed out of New York, bound for Liverpool, carrying a record number of children and infants. The passengers were surprisingly at ease, even though Germany had declared the seas around Britain to be a war zone. For months, German U-boats had brought terror to the North Atlantic.

In this illuminating book, brain scientist and horsewoman Janet Jones describes human and equine brains working together. Using plain language, she explores the differences and similarities between equine and human ways of negotiating the world. Mental abilities—like seeing, learning, fearing, trusting, and focusing—are discussed from both human and horse perspectives. Throughout, true stories of horses and handlers attempting to understand each other—sometimes successfully, sometimes not—help to illustrate the principles.

Something new entered our world in November 2022—the first general purpose AI that could pass for a human and do the kinds of creative, innovative work that only humans could do previously. Wharton professor Ethan Mollick immediately understood what ChatGPT meant: after millions of years on our own, humans had developed a kind of co-intelligence that could augment, or even replace, human thinking. Through his writing, speaking, and teaching, Mollick has become one of the most prominent and provocative explainers of AI.

Here for the first time, in rich human, political, and scientific detail, is the complete story of how the bomb was developed, from the turn-of-the-century discovery of the vast energy locked inside the atom to the dropping of the first bombs on Japan. Few great discoveries have evolved so swiftly - or have been so misunderstood. From the theoretical discussions of nuclear energy to the bright glare of Trinity, there was a span of hardly more than 25 years.

Why did humans abandon hunting and gathering for sedentary communities dependent on livestock and cereal grains and governed by precursors of today's states? Most people believe that plant and animal domestication allowed humans, finally, to settle down and form agricultural villages, towns, and states, which made possible civilization, law, public order, and a presumably secure way of living. But archaeological and historical evidence challenges this narrative.

How can we make intelligent decisions about our increasingly technology-driven lives if we don’t understand the difference between the myths of pseudoscience and the testable hypotheses of science? Pulitzer Prize-winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions.

Imagine one day you receive a letter in the mail that informs you that a large energy company is planning to build a massive pipeline through your property. That they have the legal right to do so, whether you like it or not, because this project is in the "public interest"-because the pipeline will be carrying natural gas, the so-called "bridge fuel" that politicians have been peddling for decades as the path to a clean, green energy future.

Sean Carroll is creating a profoundly new approach to sharing physics with a broad audience, one that goes beyond analogies to show how physicists really think. He cuts to the bare mathematical essence of our most profound theories, explaining every step in a uniquely accessible way. Quantum field theory is how modern physics describes nature at its most profound level. Starting with the basics of quantum mechanics itself, Sean Carroll explains measurement and entanglement before explaining how the world is really made of fields.

Having done field work in New Guinea for more than 30 years, Jared Diamond presents the geographical and ecological factors that have shaped the modern world. From the viewpoint of an evolutionary biologist, he highlights the broadest movements both literal and conceptual on every continent since the Ice Age, and examines societal advances such as writing, religion, government, and technology.

From a talent who’s been compared to Annie Dillard, Edward Abbey, David Quammen, and Jared Diamond, On Trails is a wondrous exploration of how trails help us understand the world—from invisible ant trails to hiking paths that span continents, from interstate highways to the Internet.
