Nicole Oresme [SEP] Mathematics
Oresme's most important contributions to mathematics are contained in "Tractatus de configurationibus qualitatum et motuum". In a quality, or accidental form, such as heat, he distinguished the "intensio" (the degree of heat at each point) and the "extensio" (as the length of the heated rod). These two terms were often replaced by "latitudo" and "longitudo". For the sake of clarity, Oresme conceived the idea of visualizing these concepts by plane figures, approaching what we would now call rectangular co-ordinates. The intensity of the quality was represented by a length or "latitudo" proportional to the intensity erected perpendicular to the base at a given point on the base line, which represents the "longitudo".
