Gases are all around us—they fill our lungs, power our movement, create stars, and warm our atmosphere. Often invisible and sometimes odorless, these ubiquitous substances are also the least understood materials in our world, and always have been. It wasn’t long ago that gases were seen as the work of ancient spirits: the sudden closing of a door after a change in airflow signaled a ghost’s presence.

Have you ever wondered what makes dough rise? Or how your morning coffee gives you that energy boost? Or why your shampoo is making your hair look greasy? The answer is chemistry.

Some of engineering's mightiest achievements are small in scale, even hidden—and yet, without them, the complex machinery on which our modern world runs would not exist. In Nuts and Bolts, Roma Agrawal examines seven of these extraordinary elements: the nail, the wheel, the spring, the lens, the magnet, the string, and the pump. From the physics behind both Roman nails and modern skyscrapers to rudimentary springs that inspired lithium batteries, Agrawal shows us how even the most sophisticated items are built on the foundations of these ancient and fundamental breakthroughs in engineering.

Understanding our humanity - the essence of who we are - is one of the deepest mysteries and biggest challenges in modern science. Why do we have bad moods? Why are we capable of having such strange dreams? How can metaphors in our language hold such sway on our actions? As we learn more about the mechanisms of human behavior through evolutionary biology, neuroscience, anthropology, and other related fields, we're discovering just how intriguing the human species is.

History is the most dangerous place on earth. From dinosaurs the size of locomotives to meteors big enough to sterilize the planet, from famines to pandemics, from tornadoes to the Chicxulub asteroid, the odds of human survival are slim but not zero—at least, not if you know where to go and what to do. In each chapter of How to Survive History, Cody Cassidy explores how to survive one of history’s greatest threats: getting eaten by dinosaurs, being destroyed by the asteroid that wiped out the dinosaurs, succumbing to the lava flows of Pompeii, being devoured by the Donner Party, and more.
