Experimental investigation of information processing under irreversible Brownian conditions: work/time analysis of paper chromatograms.
A wet laboratory study of chemical information processing in Brownian (random walk) environments is presented. Point samples of adsorbed dyes were subject to diffusion on paper chromatography sheets; the resulting images were recorded digitally using an office scanner. The experiments enabled the measurement of four types of information along with the attendant costs of work and time. The data are examined for their statistical distribution and scaling properties and Fourier spectral components. Whereas theory, calculations, and reversible pathways were central to the previous paper, the present study is devoted to experiments and irreversible transformations. Overall, the results establish several key points about information of four varieties purchased in real-time Brownian venues. The points concern the kinetics of information, memory effects, and the distributions of information changes with energy.
