From a spinning galaxy to a swarm of honeybees, rotating spirals are widespread in nature. Their widespread presence in nature has made the study of spiral waves relevant across various disciplines. In physical systems like fluid flows, liquid crystals, galactic formations, etc., in biological systems like the heart, chicken retina, neocortex, slime mould, etc., in chemical systems like the Belousov-Zhabotinsky (BZ) reaction system, the Briggs-Rauscher reaction, some simple precipitation processes, the oxidation of CO on platinum surfaces, etc., scientists have observed and studied spiral waves. Despite these studies, the ambiguity of spiral waves has prevented scientists from developing a comprehensive hypothesisenInteractionSynchronizationThesis
