Ferreira "], "item_description" : "The first complete biography of Einstein's Theory of General Relativity, revealing the personal feuds and ideological battles, the decades of neglect, the resurgence, and now, the deep questioning of a theory that has given us black holes, dark energy, and modern cosmology.How did one elegant theory incite a scientific revolution?Physicists have been exploring, debating, and questioning the general theory of relativity ever since Albert Einstein first presented it in 1915. In this sweeping narrative of science and culture, astrophysicist Pedro Ferreira brings general relativity to life through the story of the brilliant physicists, mathematicians, and astronomers who have taken up its challenge. Its adherents have revealed what lies at the farthest reaches of the universe, shed light on the smallest scales of existence, and explained how the fabric of reality emerges. Dark matter, dark energy, black holes, and string theory are all progeny of Einstein's theory.We are in the midst of a momentous transformation in modern physics. As scientists look farther and more clearly into space than ever before, The Perfect Theory reveals the greater relevance of general relativity, showing us where it started, where it has led, and where it can still take us.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/0/54/448/386/0544483863_b.jpg", "price_data" : { "retail_price" : "15.95", "online_price" : "15.95", "our_price" : "15.95", "club_price" : "15.95", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
