Phosphorus has played a critical role in some of the most lethal substances on earth: firebombs, rat poison, nerve gas. But it’s also the key component of one of the most vital: fertilizer, which has sustained life for billions of people.

If you have a chemistry exam tomorrow, thank goodness you're here. This book will help you memorize the entire periodic table in the fastest and easiest way possible. Would you like to remember the name of every single chemical element? And know their atomic numbers, too? If you've ever watched someone memorize a deck of playing cards in minutes, and dreamed about what you could do with a memory like that - your dreams are about to come true.

For centuries, scientists believed that living matter possessed a special quality—a spirit or essence—that differentiated it from nonliving matter. But by the nineteenth century, the scientific consensus was that the building blocks of one were identical to the building blocks of the other. Elixir tells the story of two young chemists who were not convinced, and how their work rewrote the boundary between life and nonlife.

Written by award-winning science writer John Emsley, this informative and highly enjoyable book explains the what, the why and the wherefore of the elements. Arranged alphabetically, from Actinium to Zirconium, it is a complete guide to all the elements that are currently known, with more extensive coverage of those we encounter in our everyday life. The entry on each element reveals where it came from, what role it may have in the human body, the foods that contain it, how it was discovered, its role in human health, the uses and misuses to which it is put, and its environmental role.

In 2016, with the addition of four final elements - nihonium, moscovium, tennessine and oganesson - to make a total of 118 elements, the periodic table was finally complete, rendering any pre-existing books on the subject obsolete. Tim James, the secondary-school science teacher we all wish we'd had, provides an accessible and wonderfully entertaining 'biography of chemistry' that uses stories to explain the positions and patterns of elements in the periodic table.

Where PiHKAL focuses on a class of compounds called phenethylamines, TiHKAL is written about a family of psychoactive drugs known as tryptamines with TiHKAL being an acronym for Tryptamines I Have Known and Loved”. Like its predecessor, this book is divided into two parts. The first part of the book begins with the story of Alice and Shura, a fictionalized autobiography, which picks up where the similar section of PiHKAL left off. The book opens with the story about the DEA raid that occurred a few years after the publication of their first book, PiHKAL.

Crave answers? A Feast of Science demystifies the chemistry of everyday life, serving up practical knowledge to both inform and entertain. Guaranteed to satiate your hunger for palatable and relevant scientific information, Dr. Joe Schwarcz proves that "chemical" is not necessarily synonymous with "toxic".

Seventy years ago, Erwin Schrdinger posed a simple, yet profound, question: What is life?. How could the very existence of such extraordinary chemical systems be understood? This problem has puzzled biologists and physical scientists both before, and ever since. Living things are hugely complex and have unique properties, such as self-maintenance and apparently purposeful behaviour which we do not see in inert matter. So how does chemistry give rise to biology?

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 dietary and nutritional claims pitched to us, what can we believe? How does cinnamon affect your health? How splendid is Splenda? Should you buy farmed, wild, or canned food? What's fishy about fish-oil supplements? Will a diet of Twinkies and M&M's lead to weight loss? Water from a tap or from a plastic bottle - which should you choose, and which is better for the environment? Should you carry your groceries home in plastic or brown paper? We all have questions, and Dr. Joe Schwarcz has the answers, some of which will astonish you.

In The Alchemy of Us, scientist and science writer Ainissa Ramirez examines eight inventions - clocks, steel rails, copper communication cables, photographic film, light bulbs, hard disks, scientific labware, and silicon chips - and reveals how they shaped the human experience. Ramirez tells the stories of the woman who sold time, the inventor who inspired Edison, and the hotheaded undertaker whose invention pointed the way to the computer.

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.

Eat this and live to 100. Don’t, and die. Today, hyperboles dominate the media, which makes parsing science from fiction an arduous task when deciding what to eat, what chemicals to avoid, and what’s best for the environment. In Is That a Fact?, best-selling author Dr. Joe Schwarcz carefully navigates the storm of misinformation to help us separate fact from folly and shrewdness from foolishness.

The internet is a powerful beast when it comes to science; the answer to any query you may have is just a few keystrokes away. Dr. Joe takes a critical look at how facts are misconstrued in the media. He debunks the myths surrounding canned food, artificial dyes, SPF, homeopathy, cancer, chemicals, and more.

In The Secrets of Alchemy, Lawrence M. Principe, one of the world's leading authorities on the subject, brings alchemy out of the shadows and restores it to its important place in human history and culture. By surveying what alchemy was and how it began, developed, and overlapped with a range of ideas and pursuits, Principe illuminates the practice. He vividly depicts the place of alchemy during its heyday in early modern Europe, and then explores how alchemy has fit into wider views of the cosmos and humanity.

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.

The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells - assemblies of otherwise "dead" molecules - come to life, and together constitute a living being? In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.

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.

Cheese puffs. Coffee. Sunscreen. Vapes. George Zaidan reveals what will kill you, what won’t, and why - explained with high-octane hilarity, hysterical hijinks, and other things that don’t begin with the letter H. Ingredients offers the perspective of a chemist on the stuff we eat, drink, inhale, and smear on ourselves. Apart from the burning question of whether you should eat that Cheeto, Zaidan explores a range of topics.
