What is the world made of? Ancient philosophers postulated four or five elements. Much later Dimitri Mendeleev (1869) and Lothar Meyer (1870) extended the quest to a rapidly expanding table of chemical elements. Using spectral analysis techniques that they had pioneered earlier, Kirchhoff and Bunsen (1860, 1861) discovered Fraunhofer lines in the solar spectrum, which showed that the elements found on Earth also existed in stars, though in different proportions. The abundance tabulations of Goldschmidt (1938) and later Suess and Urey (1956) showed a standard pattern for the solar system, which astronomers today extend for objects throughout the cosmos. How could all those observations be explained? In 1957, independent of each other, two te...
