PERIODIC TABLE of the ELEMENTS

In the 1860s, English chemist John Newland showed that all the chemical elements fall into eight families. Since Pythagorean mysticism was unfashionable at that time, Newland was literally laughed at and rejected by the Royal Chemical Society. In the 1870s, with much more detail than Newland, the Russian chemist Mendeleyev proved once and for all that the elements do, indeed, fall into eight families. His Periodic Table of the Elements, an octave of hauntingly Pythagorean harmony, hangs in every high-school chemistry class today. (The Royal Society later apologized to Newland and gave him a Gold Medal.)
