Julius Lothar Meyer
In 1869, Dmitri Mendeleev published a periodic table of all known elements (he predicted several new elements to complete the table, and corrected some atomic weights). A few months later, Meyer published a revised and expanded version of his 1864 table independently, which was similar to that published by Mendeleev (Meyer had been sent a copy of Mendeleev's table earlier; Mendeleev had sent it to many well-known chemists of his day) and a paper showing graphically the periodicity of the elements as a function of atomic weight. Meyer, as well as other chemists, was doubtful about Mendeleev's periodic law, and he criticized Mendeleev for "changing existing elements' atomic weights, only regarding possibility of periodical law in its structure". However, Mendeleev's work received significant support, when the new elements were found as predicted and atomic weights accordingly.
Tables (board game)
The τάβλη of Zeno's time is believed to be a direct descendant of the earlier ancient Roman "Ludus duodecim scriptorum" ("game of twelve lines" or, better, "game of twelve signs") with that board's middle row of points removed, and only the two outer rows remaining. Ludus duodecim scriptorum used a board with three rows of 12 points each, and the pieces were moved across all three rows according to the roll of three dice. The earliest known mention of the game is in Ovid's "Ars Amatoria" ("The Art of Love") (written between 1 BC and 8 AD).
In the 11th century Shahnameh, the Persian poet Ferdowsi credits Burzoe with the invention of "nard" in the 6th century. He describes an encounter between Burzoe and a Raja visiting from India. The Raja introduces the game of chess, and Burzoe demonstrates nard, played with dice made from ivory and teak.
