Mathematics Tue, 18 Jun 2019 07:14:46 EDTnews480060876The hidden structure of the periodic systemThe periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to Dmitri Mendeleev and Lothar Meyer and the approaches of other chemists to organize the elements, involve different forms of representation of a hidden structure of the chemical elements. This is the conclusion reached by researchers at the Max Planck Institute for Mathematics in the Sciences in Leipzig and the University of Leipzig in a recent paper. The mathematical approach of the Leipzig scientists is very general and can provide many different periodic systems depending on the principle of order and classification—not only for chemistry, but also for many other fields of knowledge.

The continuous gentle, wavy hills and wide valleys of the Carpathians, Appalachians or lower parts of the Alps contrast strongly with the soaring peaks, ragged ridges and deep ravines of the high Tatra mountains and Pyrenees, which are, in turn, different from the inaccessible, snow-covered Himalayan or Andean giants, along whose slopes flow long tongues of glaciers instead of water. Beneath this great diversity, however, lies a surprisingly similar structure.

The "Babylonian" method we learn at school requires us to multiply each digit of the first number by each digit of the second one. But when both numbers have a billion digits each, that means a billion times a billion or 1018 operations.
