The world has lost one of its great theoretical physicists, Dr. Steven Weinberg, 1979 Nobel laureate. Weinberg was also a great writer, authoring a series of influential textbooks, as well as works for the general public. DTLR has always been admirer of his general writing.
The New York Review of Books, to which he was a longtime contributor, has made this 2001 essay by him available for reading in his honor. I strongly recommend it.
