He created a chemical reaction between different salts and acids that swing back and forth between being yellow and clear because the concentration of the different components changes up and down in a cyclic way.
But modern theoretical analyses shows sufficiently complicated reactions can indeed comprise wave phenomena without breaking the laws of nature.
This still leaves the need for computation, performed by conventional microchips using the binary code transmitting and changing ones and zeros through a complicated system of logic gates.
In 2014, a chemical computing system was developed by an international team headed by the Swiss Federal Laboratories for Materials Science and Technology (Empa).
[8][9] In 2015, University of Washington students created a programming language for chemical reactions (originally developed for DNA analysis).
[13] In 2020, University of Glasgow researchers created a chemical computer using 3D-printed parts and magnetic stirrers in order to control the oscillations of BZ medium.
