Here in part 2 of our continuing remembrance of Steven Weinberg, we’re diving a little deeper into what we know because of him. Weinberg was one of the world’s greatest theoretical physicists, and his passing last year was deeply felt not only by us here at The University of Texas at Austin, but by a broad community of scientists and science-loving people. Weinberg summed up the goal of his life’s work as: “to know why things are the way they are.” To him, that meant distilling the rules of physics down to their simplest, most beautiful essence.
