• This work demonstrates the computational power of a hydrodynamic photochemical oscillator based on a photochromic naphthopyran generating aperiodic time series. The chaotic character of the time series is tested by calculating its largest Lyapunov exponent and the correlation dimension of its attractor after building its phase space through the Takens’ theorem. Then, the chaotic dynamic is shown to be suitable to implement all the fundamental Boolean two‐inputs‐one‐output logic gates. Finally, the strategy to implement fuzzy logic systems (FLSs) based on the time series is described. Such FLSs promise to be useful in the field of computational linguistics, which is concerned with the development of artificial intelligent systems able to transform collections of numerical data into natural language texts. Chaos‐based computing: A chaotic hydrodynamic photochemical oscillator based on a thermally reversible photochromic naphthopyran acts as a universal Turing machine. All the fundamental binary logic gates can be implemented. Moreover, fuzzy logic systems based on the aperiodic time series can transform numerical data into linguistic statements and contribute to the development of computational linguistics.
