This book explores the Micro-World of subatomic particles and forces, including the recently discovered Higgs boson. The pursuit of nature’s smallest parts is one of mankind’s oldest quests, beginning at least 26 centuries ago. But, just in our lifetimes it seems we’ve finally “hit bottom.” Each step deeper into the Micro-World has revealed surprises, and expanded our understanding of nature on all size scales. At the bottom, we see a remarkable unity — nature is the same everywh...

This book continues our exploration of the most profound theory of science, Einstein’s General Theory of Relativity. We examine more carefully the properties of spacetime, the unity of space and time. We explore the major features of curvature, how to measure it, and how to reduce its complexity to finding distances between nearby points. We find a simple expression, 2M/r, which proves remarkably helpful as we explore the Schwarzchild metric, black holes, time d...
