I'm not sure about philosophy, but for physics, the most elegant expression of new discoveries is mathematical equations and numeric measurements. The words used by the original discoverer are not that important, because they just introduce the equations and numbers and provide context. When they appear in textbooks, the equations are usually expressed in the same form as the original discoverer expressed them, so in that sense, you are reading the original (equations).
