While researching the toxic and addictive properties of sugar for Fat Chance, Robert Lustig made an alarming discovery - our pursuit of happiness is being subverted by a culture of addiction and depression from which we may never recover. Dopamine is the "reward" neurotransmitter that tells our brains we want more; yet every substance or behavior that releases dopamine in the extreme leads to addiction. Serotonin is the "contentment" neurotransmitter that tells our brains we don't need any more; yet its deficiency leads to depression.

The deep-learning revolution has brought us driverless cars, the greatly improved Google Translate, fluent conversations with Siri and Alexa, and enormous profits from automated trading on the New York Stock Exchange. Deep-learning networks can play poker better than professional poker players and defeat a world champion at Go. In this book, Terry Sejnowski explains how deep learning went from being an arcane academic field to a disruptive technology in the information economy.

How is it possible for the disciplines of cosmology, geology, anthropology, biology, and history to fit together? These 48 lectures answer that question by weaving a single story from accounts of the past developed by a variety of scholarly disciplines. The result is a story stretching from the origins of the universe to the present day and beyond, in which human history is seen as part of the history of our Earth and biosphere, and the Earth's history, in turn, is seen as part of the history of the universe.

Not only can we not currently explain the origin of the universe, it is questionable we will ever be able to explain it. The notion that there are universes within particles, or that particles are conscious, is ascientific, as is the hypothesis that our universe is a computer simulation. On the other hand, the idea that the universe itself is conscious is difficult to rule out entirely.

Geneticists like David Reich have made astounding advances in the field of genomics, which is proving to be as important as archaeology, linguistics, and written records as a means to understand our ancestry. In Who We Are and How We Got Here, Reich allows listeners to discover how the human genome provides not only all the information a human embryo needs to develop but also the hidden story of our species.

In Reconnecting to the Source he unpacks the science behind spiritual experience, investigating the ways in which we can access realms of experience beyond the everyday. It is in these moments, when our conscious minds are in contact or perhaps even overridden by our unconscious selves, that we can explore the depths of spiritual meaning. In addition to a foreword by Deepak Chopra, the book includes new, never before published contributions from a long list of well-known writers and public figures.

What would it be like to visit the ancient landscapes of the past? To experience the Jurassic or Cambrian worlds, to wander among these other lands, as creatures extinct for millions of years roam? In this mesmerizing debut, award-winning palaeontologist Thomas Halliday gives us a breath-taking up-close encounter with worlds that are normally unimaginably distant.

Physicists have been exploring, debating, and questioning the general theory of relativity ever since Albert Einstein first presented itin 1915. Their work has uncovered a number of the universe's more surprising secrets, and many believe further wonders remain hidden within the theory's tangle of equations, waiting to be exposed. In this sweeping narrative of science and culture, astrophysicist Pedro Ferreira brings general relativity to life through the story of the brilliant physicists, mathematicians, and astronomers who have taken up its challenge.

Emily Dickinson and Charles Darwin were born at a time when the science of studying the natural world was known as natural philosophy, a pastime for poets, priests, and schoolgirls. The world began to change in the 1830s, while Darwin was exploring the Pacific aboard the Beagle and Dickinson was a student in Amherst, Massachusetts. Poetry and science started to grow apart, and modern thinkers challenged the old orthodoxies, offering thrilling new perspectives that suddenly felt radical—and too dangerous for women.

Economist Steve Keen talks to Phil Dobbie about the failings of the neoclassical economics and how it reflects on society. Hosted on Acast. See acast.com/privacy for more information.

Travelling at almost 18,000 miles per hour - 10 times faster than a rifle bullet - Yuri Gagarin circles the globe in just 106 minutes. From his windows, he sees the Earth as nobody has before, crossing a sunset and a sunrise, crossing oceans and continents, witnessing its beauty and its fragility. While his launch begins in total secrecy, within hours of his landing, he has become a world celebrity - the first human to leave the planet. Beyond tells the thrilling story behind that epic flight on its 60th anniversary.

In our unique genomes, every one of us carries the story of our species - births, deaths, disease, war, famine, migration, and a lot of sex. But those stories have always been locked away - until now. Who are our ancestors? Where did they come from? Geneticists have suddenly become historians, and the hard evidence in our DNA has completely upended what we thought we knew about ourselves. Acclaimed science writer Adam Rutherford explains exactly how genomics is completely rewriting the human story - from 100,000 years ago to the present.

In Jared Diamond’s follow-up to the Pulitzer-Prize winning Guns, Germs and Steel, the author explores how climate change, the population explosion, and political discord create the conditions for the collapse of civilization. Environmental damage, climate change, globalization, rapid population growth, and unwise political choices were all factors in the demise of societies around the world, but some found solutions and persisted.

Albert Einstein and Erwin Schrödinger were friends and comrades-in-arms against what they considered the most preposterous aspects of quantum physics: its indeterminacy. Einstein famously quipped that God does not play dice with the universe, and Schrödinger is equally well known for his thought experiment about the cat in the box who ends up "spread out" in a probabilistic state, neither wholly alive nor wholly dead.

Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. In order to solve this mystery, Hawking studied the big bang origin of the universe, but his early work ran into a crisis when the math predicted many big bangs producing a multiverse—countless different universes, most of which would be far too bizarre to ​harbor life.

In The Quantum Universe, Brian Cox and Jeff Forshaw approach the world of quantum mechanics in the same way they did in Why Does E=mc2? and make fundamental scientific principles accessible - and fascinating - to everyone.The subatomic realm has a reputation for weirdness, spawning any number of profound misunderstandings, journeys into Eastern mysticism, and woolly pronouncements on the interconnectedness of all things. Cox and Forshaw's contention? There is no need for quantum mechanics to be viewed this way.

A wide ranging discussion of consciousness at the intersection of science and spirituality with Rupert Sheldrake, PhD, a biologist and author best known for his hypothesis of morphic resonance. At Cambridge University Rupert worked in developmental biology as a Fellow of Clare College. He was Principal Plant Physiologist at the International Crops Research Institute for the Semi-Arid Tropics in Hyderabad, India. From 2005 to 2010 he was Director of the Perrott-Warrick project for research on unexplained human and animal abilities, funded by Trinity College, Cambridge.

Few perspectives epitomize the sheer drama and sacrifice of combat more perfectly than those of the fighter pilots of World War II. As romanticized as any soldier in history, the World War II fighter pilot was viewed as larger than life: a dashing soul waging war amongst the clouds. In the 65-plus years since the Allied victory, stories of these pilots' heroics have never been in short supply. But what about their adversaries - the highly skilled German aviators who pushed the Allies to the very brink of defeat?

An almost limitless archive of our history lies hidden inside our bodies, and this book traces the ancient story of Scotland from that scientific viewpoint. The mushrooming of genetic studies, of DNA analysis, is rewriting history in spectacular fashion. In Scotland: A Genetic Journey, Alistair Moffat explores the history that is printed on our genes, and in a remarkable new approach, uncovers the detail of where Scots are from, where they have journeyed, and who they are - and in so doing, vividly colors in a DNA map of Scotland.

A couple working six months per year for 50 hours per week on 20 acres can net $25,000 to $30,000 per year with an investment equivalent to the price of one new medium-sized tractor. Seldom has agriculture held out such a plum. In a day when mainline farm experts predict the continued demise of the family farm, the pastured poultry opportunity shines like a beacon in the night, guiding the way to a brighter future.
