LOOP QUANTUM GRAVITY FOR EVERYONE PDF

"In this remarkably well-written text, the authors introduce readers gently to the conceptual bricks of LQG without using any mathematics (quite an achievement). The debate started with the discovery that the space-time geometry of general relativity can be written in terms of the electromagnetic field. This led to intersecting graphs called loops. Now known as spin networks, they are the foundations of LQG. This slender volume discusses applications of LQG to black holes and cosmology and introduces the notion of spin foam, acknowledging that as yet the theory, though elegant, has no experimental confirmation … This book offers a fascinating introduction to an esoteric realm otherwise accessible to only a fortunate few.

Summing Up: Highly recommended. Upper-division undergraduates. Graduate students and faculty researchers."
