The Holy Grail of modern physics is a theory of the universethat unites two seemingly opposing pillars of modern science:Einstein's theory of general relativity, which deals withlarge-scale phenomena (planets, solar systems and galaxies), andquantum theory, which deals with the world of the very small(molecules, atoms, electrons). In Three Roads to Quantum Gravity,Lee Smolin provides the first concise and accessible overview ofcurrent attempts to reconcile these two theories in a final "theoryof everything. " This is the closest anyone has ever come todevising a completely new theory of space, time and the universe toreplace the Newtonian ideas that were the foundation of all scienceuntil the beginning of the twentieth century. Lee Smolin, who hasspent his career at the forefront of these new discoveries,presents for the first time the main ideas behind the newdevelopments that have brought a quantum theory of gravity insight. He explains in simple terms what scientists are talkingabout when they say the world is made from exotic entities such asloops, strings, and black holes. As he does so, he tells thefascinating stories behind these discoveries: the rivalries,epiphanies, and intrigues he witnessed firsthand. Science MastersSeries
