The Belousov-Zhabotinsky reaction, or BZ reaction, is a chemical reaction that results in the spontaneous formation of complex patterns with oscillating colors. This reaction is also known by various synonyms, including the BZ wave, BZ oscillations, and BZ phenomenon. Another synonym for the BZ reaction is the "Brusselator" reaction, named after Russian mathematician Ilya Prigogine's Brusselator model of the reaction. The BZ reaction is also sometimes called the "reaction-diffusion system" due to its ability to create dynamic patterns through the reaction and diffusion of its constituent chemicals. Overall, these synonyms describe the fascinating and intricate patterns that emerge from the chemical reactions within the BZ system.
