Block by Block offers an original perspective on thermodynamic science and history based on the three approaches of a practicing engineer, academician, and historian. The book synthesizes and gathers into one accessible volume a strategic range of foundational topics involving the atomic theory, energy, entropy, and the laws of thermodynamics.

Napoleon's Buttons is the fascinating account of 17 groups of molecules that have greatly influenced the course of history. These molecules provided the impetus for early exploration, and made possible the voyages of discovery that ensued. The molecules resulted in grand feats of engineering and spurred advances in medicine and law; they determined what we now eat, drink, and wear. A change as small as the position of an atom can lead to enormous alterations in the properties of a substance.

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.

For decades, biology has been dominated by the study of genetic information. Information is important, but it is only part of what makes us alive. Our inheritance also includes our living metabolic network, a flame passed from generation to generation, right back to the origin of life. In Transformer, biochemist Nick Lane reveals a scientific renaissance that is hiding in plain sight-how the same simple chemistry gives rise to life and causes our demise.

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 this new collection of bite-size pop science essays, bestselling author, chemistry professor, and radio broadcaster Dr. Joe Schwarcz shows that you can find science virtually anywhere you look. And the closer you look, the more fascinating it becomes.

No journalist has ever been allowed into the ultrasecretive, highly pressured process of originating a perfume. But Chandler Burr, the New York Times perfume critic, spent a year behind the scenes observing the creation of two major fragrances.

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.

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.

Chemistry for Breakfast is a perfect book for anyone who wants to deepen their understanding of chemistry without having prior knowledge of the science. With Mai as your guide, you'll find something fascinating everywhere around you.

In both history and fiction, some of the most dramatic, notorious deaths have been through poisonings. Concealed and deliberate, it's a crime that requires advance planning and that for many centuries could go virtually undetected. And yet there is a fine line between healing and killing: The difference lies only in the dosage!

Known as Monsanto's Roundup by consumers, and as glyphosate by scientists, the world's most popular weed killer is used everywhere from backyard gardens to golf courses to millions of acres of farmland. For decades it's been touted as safe enough to drink, but a growing body of evidence indicates just the opposite, with research tying the chemical to cancers and a host of other health threats. In Whitewash, veteran journalist Carey Gillam uncovers one of the most controversial stories in the history of food and agriculture, exposing new evidence of corporate influence.

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.

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.

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.

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).

Long Hard Road provides an inside look at the birth of the lithium-ion battery, from its origins in academic labs around the world to its transition to its new role as the future of automotive power. It chronicles the piece-by-piece development of the battery, from its early years when it was met by indifference from industry to its later emergence in Japan where it served in camcorders, laptops, and cell phones. The book is the first to provide a glimpse inside the Japanese corporate culture that turned the lithium-ion chemistry into a commercial product.

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 1938, a young German rocket enthusiast named Wernher von Braun had dreams of building a rocket that could fly him to the moon. In Ray, North Dakota, a young farm girl named Mary Sherman was attending high school. In an age when girls rarely dreamed of a career in science, Mary wanted to be a chemist. A decade later, the dreams of these two disparate individuals would coalesce in ways neither could have imagined.

The iconic periodic table of the elements is now in its most satisfyingly elegant form. This is because all the "gaps" corresponding to missing elements in the seventh row, or period, have recently been filled and the elements named. But where do these names come from? For some, usually the most recent, the origins are quite obvious, but in others - even well-known elements such as oxygen or nitrogen - the roots are less clear. Here, Peter Wothers explores the fascinating and often surprising stories behind how the chemical elements received their names.
