Il premio Nobel è uno dei più prestigiosi riconoscimenti culturali che possa essere tributato a una persona. Ma è ben lungi dall’essere un vaccino contro le cantonate... fisici, chimici, medici e letterati, tutti premi Nobel, ne sono stati vittime. Il libro racconta in modo brillante e divertente le bizzarre teorie e i clamorosi errori di alcuni premi Nobel. Questo significa che il prestigioso premio svedese è una cosa poco seria? No! Dimostra soltanto che il principio di autorità nella scienza non ha alcun valore: più che l’ipse dixit, contano i fatti!

Join world-leading scientists as they delve into the incredible stories behind 16 elements, including the dark and controversial history of gold; how a solar eclipse in 1868 led to the discovery of the periodic table's most notorious escape artist, helium; the role of iron in the rise and fall of human civilisations; why you might find iodine in British milk, but not necessarily anywhere else in the world; and how a discovery in boiled urine led to the trade union movement and a chemical weapon.

NASA Astrobiologist and renowned scientist Dr. David Grinspoon brings listeners an optimistic message about humanity's future in the face of climate change. For the first time in Earth's history, our planet is experiencing a confluence of rapidly accelerating changes prompted by one species: Humans. Climate change is only the most visible of the modifications we've made - up until this point, inadvertently - to the planet. And our current behavior threatens not only our own future but that of countless other creatures.

Explore the universe and immerse yourself in the story of our solar system, planet, and life through meteorites.

The complex ecosystem of the Amazon covers an area about the size of the continental US. Approximately one of every four flowering plant species on earth resides in the Amazon. A single Amazonian river may contain more fish species than all the rivers in Europe combined. The rain forest, which contains approximately 390 billion trees, plays a vital role in stabilizing the global climate by absorbing massive amounts of carbon dioxide - or releasing it into the atmosphere if the trees are destroyed.

We all know that without water we couldn't survive, and that sometimes a cup of coffee or a glass of wine feels just as vital. But do we really understand how much we rely on liquids, or the destructive power they hold? Set over the course of a flight from London to San Francisco, Liquid Rules offers listeners a fascinating tour of these formless substances, told through the language of molecules, droplets, heartbeats, and ocean waves.

Of all the radioactive elements discovered at the end of the 19th century, it was radium that became the focus of both public fascination and entrepreneurial zeal. Half Lives tells the fascinating, curious, sometimes macabre story of the element through its ascendance as a desirable item - a present for a queen, a prize in a treasure hunt, a glow-in-the-dark dance costume - to its role as a supposed cure-all in everyday 20th-century life, when medical practitioners and business people (reputable and otherwise) devised ingenious ways of commodifying the new wonder element.

Scratch beneath the surface of a coffee bean, a red pepper flake, a poppy seed, a mold spore, a foxglove leaf, a magic-mushroom cap, a marijuana bud, or an apple seed, and we find a bevy of strange chemicals. We use these to greet our days (caffeine), titillate our tongues (capsaicin), recover from surgery (opioids), cure infections (penicillin), mend our hearts (digoxin), bend our minds (psilocybin), calm our nerves (CBD), and even kill our enemies (cyanide). But why do plants and fungi produce such chemicals? And how did we come to use and abuse some of them?

When you're cooking, you're a chemist! Every time you follow or modify a recipe you are experimenting with acids and bases, emulsions and suspensions, gels and foams. In your kitchen you denature proteins, crystallize compounds, react enzymes with substrates, and nurture desired microbial life while suppressing harmful microbes. And unlike in a laboratory, you can eat your experiments to verify your hypotheses.

In The Elements We Live By, physicist and award-winning author Anja Røyne takes us on an astonishing journey through chemistry and physics, introducing the building blocks from which we humans - and the world - are made. Not only does Røyne explain why our bodies need iron, phosphorus, silicon, potassium, and many more elements in just the right amounts in order to function, she also leads us around the world to where these precious elements are found (some of them in ever-shrinking quantities).

Like the alphabet, the calendar, or the zodiac, the periodic table of the chemical elements has a permanent place in our imagination. But aside from the handful of common ones (iron, carbon, copper, gold), the elements themselves remain wrapped in mystery. We do not know what most of them look like, how they exist in nature, how they got their names, or of what use they are to us.

In Slime we'll meet the algae innovators working toward a sustainable future: from seaweed farmers in South Korea, to scientists using it to clean the dead zones in our waterways, to the entrepreneurs fighting to bring algae fuel and plastics to market. Ruth Kassinger takes listeners on an around-the-world, behind-the-scenes, and into-the-kitchen tour. Whether you thought algae was just the gunk in your fish tank or you eat seaweed with your oatmeal, Slime will delight and amaze with its stories of the good, the bad, and the up-and-coming.

In this fascinating, refreshingly clarifying book about food, food myths, and how sloppy science perpetuates misconceptions about food, a medical doctor on his way to a conference gets drawn into conversations that answer many questions.

The periodic table of elements, first encountered by many of us at school, provides an arrangement of the chemical elements, ordered by their atomic number, electron configuration, and recurring chemical properties, and divided into periodic trends. In this Very Short Introduction audiobook, Eric R. Scerri looks at the trends in properties of elements that led to the construction of the table and shows how the deeper meaning of the table's structure gradually became apparent with the development of atomic theory.

In Proof, Adam Rogers reveals alcohol as a miracle of science, going deep into the pleasures of making and drinking booze—and the effects of the latter. The people who make and sell alcohol may talk about history and tradition, but alcohol production is really powered by physics, molecular biology, organic chemistry, and a bit of metallurgy—and our taste for those products is a melding of psychology and neurobiology.

This book will appeal to foodies and those who are deprived of cookbooks in audio format. Molecular Gastronomy documents the sensory phenomena of eating and uses basic physics to put to bed many culinary myths. This audiobook presents pieces of conventional wisdom - such as whether it is better to make a stock by placing meat in already boiling water, or water before it is boiled - and gives its history before making scientific pronouncements.

From the creator of the wildly popular xkcd, What If? gives hilarious and informative answers to important questions you probably never thought to ask. Millions visit xkcd.com each week to read Randall Munroe's iconic webcomic. Fans ask him a lot of strange questions. How fast can you hit a speed bump, driving, and live? When (if ever) did the sun go down on the British Empire? When will Facebook contain more profiles of dead people than living?

Science and technology are, without a doubt, two forces that will change the way you live your life in the coming months, years, and decades. And in recent decades, these forces have evolved and developed at a lightning-fast pace. Explore the many possibilities of what your future may look like with these 24 lectures: a scientifically accurate and enlightening survey of today's most advanced research in fields such as engineering, biology, chemistry, and theoretical physics.
