Trivia

An interesting fact about Polarimeter is that it was actually invented in 1815, by Jean-Baptiste Biot and François Arago. This was a remarkable accomplishment considering the technology of the time. The device was used to measure the angle of rotation between two polarized beams of light. The invention of the Polarimeter was revolutionary, as it allowed for the first accurate measurements of the optical properties of materials. This provided a valuable tool for scientists to better understand the nature of matter. This information was critical in furthering the understanding of many physical phenomena, such as chemical reactions, light dispersion, and other physical processes. Source: Wikipedia - Polarimeter.
