Physics

Astronomy is the study of what you see in the sky. Physics is the study of how things work. Astrophysics is the study of how things in the sky work, from large objects to tiny particles. Astrophysics For Dummies breaks it all down for you, making this difficult but fascinating topic accessible to anyone. Tracking the topics covered in a typical undergraduate astrophysics class, this book will teach you the essential pieces to understanding our universe. Get ready to launch into outer space with this ever-changing branch of science.

In Countdown, science journalist Sarah Scoles uncovers a different atomic reality: the nuclear age's present. Drawing from years of on-the-ground reporting at the nation's nuclear weapons labs, Scoles interrogates the idea that having nuclear weapons keeps us safe, deterring attacks and preventing radioactive warfare. She deftly assesses the existing nuclear apparatus in the United States, taking listeners beyond the news headlines and policy-speak to reveal the state of nuclear-weapons technology.

We take time for granted as it passes during every moment of our existence. Other things may change, but time remains constant and predictable. The past, the present, and the future exist within a harmonious, reliable, and never-changing system. Or at least that’s how it seems. It was Albert Einstein who, in 1905, first theorized that time might not be quite as straightforward as that. In one of the most influential papers on physics ever published[1], he proposed something called “time dilatation.”

Embark on a mind-expanding journey through the nature of reality itself! Is our universe one of many? Are we living in a simulation? What does quantum physics tell us about the fabric of reality? "The Beginner's Guide to Reality" breaks down these profound questions into three fascinating, accessible books that will forever change how you view existence.

Journey into quantum physics - without the mathematical maze! Ever wonder how particles can exist in two places at once or why Einstein called quantum entanglement "spooky action at distance"? Quantum Physics Unplugged transforms these mind-bending concepts into clear, engaging insights that anyone can grasp.
