Photometric Researches

Focusing on the measurement of light, the book presents Charles Sanders Peirce's extensive research conducted between 1872 and 1875. It covers various aspects of photometry, including light intensity, properties of light sources, and the interplay between light intensity and color. Peirce supports his findings with detailed experimental data and mathematical calculations, while also analyzing existing literature in the field. This work is a significant contribution to photometry and serves as a valuable resource for contemporary scientists and researchers.
