An introduction to modern physics by a founder of the loop quantum gravity theory shares seven succinct lessons on topics ranging from general relativity and quantum mechanics to elementary particles and black holes.

The universe has many secrets. It may hide additional dimensions of space other than the familiar three we recognize. There might even be another universe adjacent to ours, invisible and unattainable . . . for now. Warped Passages is an altogether exhilarating journey that tracks the arc of discovery from early twentieth-century physics to the razor's edge of modern scientific theory. One of the world's leading theoretical physicists, Lisa Randall...

"Millions of people visit xkcd.com each week to read Randall Munroe's iconic webcomic. His stick-figure drawings about science, technology, language, and love have a large and passionate following. Fans of xkcd ask Munroe a lot of strange questions. What if you tried to hit a baseball pitched at 90 percent the speed of light? How fast can you hit a speed bump while driving and live? If there was a robot apocalypse, how long would humanity last? In...

New Yorker writer Malcolm Gladwell looks at why major changes in our society so often happen suddenly and unexpectedly. Ideas, behavior, messages, and products, he argues, often spread like outbreaks of infectious disease. Just as a single sick person can start an epidemic of the flu, so too can a few fare-beaters and graffiti artists fuel a subway crime wave, or a satisfied customer fill the empty tables of a new restaurant. These are social epidemics,...

Physics can explain many of the things that we commonly encounter. It can tell us why the night is dark, what causes the tides, and even how best to catch a baseball. With In Praise of Simple Physics, popular math and science writer Paul Nahin presents a plethora of situations that explore the science and math behind the wonders of everyday life. Roaming through a diverse range of puzzles, he illustrates how physics shows us ways to wring more energy...
