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 bacteria and fungi. And unlike in a laboratory, you can eat your experiments to verify your hypotheses.
In Culinary Reactions, author Simon Quellen Field turns measuring cups, stovetop burners, and mixing bowls into graduated cylinders, Bunsen burners, and beakers. How does altering the ratio of flour, sugar, yeast, salt, butter, and water affect how high bread rises? Why is whipped cream made with nitrous oxide rather than the more common carbon dioxide? And why does Hollandaise sauce call for “clarified” butter? This easy-to-follow primer even includes recipes to demonstrate the concepts being discussed, including:
· Whipped Creamsicle Topping—a foam
· Cherry Dream Cheese—a protein gel
· Lemonade with Chameleon Eggs—an acid indicator
and many more.
How much do you really know about how the human body works and how it reacts to food, exercise, nutrition, and the environment?
While most people have read about at least one fad diet, they're left wondering about the greater biochemistry,
psychology, sociology, and physiology of the obesity crisis in the United
Gut Reactions by chemist Simon Quellen Field shows readers how their bodies react to food and the environment and how their brains affect what and how much they eat.
It reveals why some diets work for some people but not for others, based on genetics, previous weight history, brain chemistry, environmental cues, and social pressures.
It explores how dozens of hormones affect hunger and satiety and interact with the brain and the gut to regulate feeding behavior.
And it explains the addictive nature of foods that interact
with the same dopamine and opioid receptors in the brain as cocaine, heroin,
amphetamines, and nicotine.
Whether you're looking to lose weight, put on muscle mass, or simply understand how your metabolism or gut microbiome impact your food cravings, Simon Quellen Field has the scientific answers for you.

Explore the reasons we age, why we age more slowly than most other animals, what goes wrong, and what to do about it. Delve into the latest science and see what is in store for the very near future.
Step-by-step instructions to building more than 30 fascinating devices are included in this book for workbench warriors and grown-up geeks.
Detailed illustrations and diagrams explain how to construct a simple radio with a soldering iron, a few basic circuits, and three shiny pennies. Instructions are included for a rotary steam engine that requires a candle, a soda can, a length of copper tubing, and just 15 minutes.
To use optics to roast a hot dog, no electricity or stove is required, just a flexible plastic mirror, a wooden box, a little algebra, and a sunny day.
Also included are experiments most science teachers probably never demonstrated, such as magnets that levitate in midair, metals that melt in hot water, a Van de Graaff generator made from a pair of empty soda cans, and lasers that transmit radio signals.
Every experiment is followed by an explanation of the applicable physics or chemistry.
This fresh collection of more than 20 science projects—from hydrogen fuel cells to computer-controlled radio transmitters—is perfect for the tireless tinkerer.
Innovative activities include taking detailed plant cell photographs through a microscope using a disposable camera; building a rocket engine out of aluminum foil, paper clips, and kitchen matches; and constructing a geodesic dome out of gumdrops and barbecue skewers.
Organized by scientific topic, each chapter includes explanations of the physics, chemistry, biology, or mathematics behind the projects.
Most of the devices can be built using common household products or components available at hardware or electronic stores, and each experiment contains illustrated step-by-step instructions with photographs and diagrams that make construction easy.
No workbench warrior, science teacher, or grown-up geek
should be without this idea-filled resource.
Black powder, the world's first chemical explosive, was originally developed in the seventh century, during China's Tang dynasty. It was a crude mixture at first, but over time chemists discovered the optimum proportion of sulfur, charcoal, and nitrates, as well as the best way to mix them so that the particles of each component were tiny and homogenous, resulting in a complete and powerful reaction.
Author and chemistry buff Simon Quellen Field takes readers on a decades-long journey through the history of things that go boom, from the early days of black powder to today's modern plastic explosives. Not just the who, when, and why, but also the how. How did Chinese alchemists come to create black powder? What accidents led to the discovery of high explosives? How do explosives actually work on a molecular scale? And though most people have a vague understanding that dynamite is more powerful than gunpowder, what does it mean to be more powerful?
Boom! The Chemistry and History of Explosives goes back to the original papers and patents written by the chemists who invented them, to shed light on their development, to explore the consequences of their use for good and ill, and to give the reader a basic understanding of the chemistry that makes them possible.
When it comes to chemistry, most kids have more questions than answers. Why do you get cavities when you eat too much sugar? How does sun block protect your skin from getting a sunburn? What makes soda so fizzy? And why do you need antifreeze in your car?
Teenager Alexa Coelho quizzed her neighbor, chemist Simon Field, with hundreds of perplexing questions, and now she has the answers. Field covers a wide variety of concepts from simple to complex, but always with straightforward, easy-to-understand explanations.
And for those readers who want to see chemistry in action, Why Is Milk White? also includes a dozen unique experiments to try at home. Lift latent fingerprints from a “crime scene” using super glue (for a glass or smooth surface) or iodine (for paper). Hollow out the zinc interior of a penny using muriatic acid, leaving only a thin copper shell. Conduct a paper chromatography experiment to separate food coloring into its component dyes. Or use easy-to-find chemicals to create plastic “slime,” Silly Putty, or a bouncing ball. This book is the perfect resource for budding scientists everywhere.

What would it be like to be genetically engineered?
To have your genes selected from thousands of the most successful athletes, scientists, businessmen, and scholars from all over the world?
Jack Wright knows, because that's just what was done to him. Growing up with the expectations of greatness, all his successes taken for granted, all his accomplishments attributed to his genes, he can run faster than any Olympian, but will never get a medal, since genetic enhancements are considered unfair competition, like performance enhancing drugs.
In a world where broad spectrum antiviral drugs have made most illnesses things of the past, including all sexually transmitted diseases, relationships form quickly and easily, without fear, except for Jack.
Living alone, the scars of growing up as a lonely superman leave him particularly at a loss when his path intersects with two women, whose secrets get them all involved with murder, gang warfare, illegal drug trading, and a mystery that Jack is uniquely suited to solve.
