This is a book about String Theory, General Relativity & Quantum Mechanics, the Black Hole, the Big Bang, the Muti-dimentional Universe, written for the general readers. General readers? They'd better be equpped with a solid grasp of undergraduated-level Physics skills, a passion for Relativity/Quantum Physics, and a lot of patience. However, the book is (almost) free from gory technical details and mathematical formulas (except for the last few chapters); it's just the complexity of modern Physics theories that requires an active and perseverant participation from the "general" but informed audience.
