“the three-dimensional world of ordinary experience—the universe filled with galaxies, stars, planets, houses, boulders, and people—is a hologram, an image of reality coded on a distant two-dimensional surface. This new law of physics, known as the Holographic Principle, asserts that everything inside a region of space can be described by bits of information restricted to the boundary”

Greene's has something that makes very easy to follow complicated topics as an intuitive ones. The books has fantastic explanations passing through the basics of general relativity, quantum mechanics and finally string theory going deeper onto such concepts as 10 "spatial" dimensions, mirror symmetry and Calabi-Yau manifolds, to be honest some paragraphs needed to be read twice to get the idea. EXCELLENT BOOK for those who love such topics!

Great book! Easy to read, an excellent historical travel through Black Holes with a very clear timeline. It‘s also technical enough to enjoy reading and understand the main points without being annoying with complicated formulas. Excellent book, highly recommended! 😊
