Just as Henry David Thoreau “traveled very much in Concord,” Nobel Prize–winning physicist Steven Weinberg sees a lot of the area from the window of his research overlooking Lake Austin. In Lake perspectives Weinberg, thought of through many to be the preeminent theoretical physicist alive at the present time, keeps the wide-ranging reflections that experience additionally earned him a name as, within the phrases of recent York occasions reporter James Glanz, “a strong author of prose which can illuminate—and sting. ”
This assortment offers Weinberg’s perspectives on subject matters starting from difficulties of cosmology to various global issues—military, political, and spiritual. while he strikes past the limits of technological know-how, each one essay displays his adventure as a theoretical physicist. And as within the celebrated dealing with Up, the essays show a perspective that's rationalist, reductionist, realist, and secular. a brand new creation precedes every one essay, explaining the way it got here to be written and bringing it modern the place necessary.
