Dreamstate

In his 2004 book In Dreams of a Final Theory, Stephen Weinberg, the Nobel Prize-winning physicist and bestselling author of The First Three Minutes describes the grand quest for a unifying theory of nature—one that can explain forces as different as the cohesion inside the atom and the gravitational tug between the sun and the earth. Writing with dazzling elegance and clarity, he retraces the steps that have led modern scientists from relativity and quantum mechanics to the notion of superstrings and the idea that our universe may coexist with others. But Weinberg asks as many questions as he answers, among them: Why does each explanation of the way nature works point to the other, deeper explanations? Why are the best theories not only logical but beautiful?
