Reminiscences about Steven Weinberg (this time it's personal)

Steven Weinberg's productive scientific life teaches us many things, one of the most important of which is the power of his example. This essay contains personal reminiscences and a speculation about gravitational wave propagation based on one of his very last papers – as seems fitting, given his penchant for putting interesting physics into the essays he wrote for other luminaries over the years. (See [1] for a less personal summary of his main scientific accomplishments.)
