Using the modern home as a springboard, Atoms Under the Floorboards presents the fascinating and surprising scientific explanations behind a variety of common (and often entertainingly mundane) household phenomena, from gurgling drains and squeaky floorboards to rubbery custard and shiny shoes.
Packed with facts and fun, each chapter focuses on the objects and processes familiar in everyday life and slowly unpicks the science behind them. For example, the chapter on how buildings work introduces static and dynamic forces in explaining why buildings (and their foundations) don't sink into the ground and why skyscrapers don't blow over in strong winds. The chapter on bicycles explores how "circles (better known as wheels) with a few flimsy bits of metal (spokes) stretched between them" are able to support your weight--and this leads into a discussion of compression, tension, and how gears work.
After reading Atoms Under the Floorboards, you'll never look at everyday objects the same way again.

This groundbreaking work of practical, popular science reveals that fat is much smarter than we think.
Fat is an obsession, a dirty word, a subject of national handwringing―and, according to biochemist Sylvia Tara, the least-understood part of our body.
You may not love your fat, but your body certainly does. In fact, your body is actually endowed with many self-defense measures to hold on to fat. For example, fat can use stem cells to regenerate; increase our appetite if it feels threatened; and use bacteria, genetics, and viruses to expand itself. The secret to losing twenty pounds? You have to work with your fat, not against it. Tara explains how your fat influences your appetite and willpower, how it defends itself when attacked, and why it grows back so quickly. The Secret Life of Fat brings cutting-edge research together with historical perspectives to reveal fat’s true identity: an endocrine organ that, in the right amount, is critical to our health. Fat triggers puberty, enables our reproductive and immune systems, and even affects brain size.
Although we spend $60 billion annually fighting fat, our efforts are often misinformed and misdirected. Tara expertly illustrates the complex role that genetics, hormones, diet, exercise, and history play in our weight, and The Secret Life of Fat sets you on the path to beat the bulge once and for all.

Readers will travel back in time to ancient Babylonia, Egypt, and Greece. They will meet the world's first astronomers, mathematicians, and physicists and explore the lives and ideas of such famous people as Pythagoras, Archimedes, Brahmagupta, al-Khwarizmi, Fibonacci, Ptolemy, St. Augustine, and St. Thomas Aquinas. Hakim will introduce them to Aristotle—one of the greatest philosophers of all time—whose scientific ideas dominated much of the world for eighteen centuries.
In the three-book The Story of Science series, master storyteller Joy Hakim narrates the evolution of scientific thought from ancient times to the present. With lively, character-driven narrative, Hakim spotlights the achievements of some of the world's greatest scientists and encourages a similiar spirit of inquiry in readers. The books include hundreds of color photographs, charts, maps, and diagrams; informative sidebars; suggestions for further reading; and excerpts from the writings of great scientists.
