FIRST EDITION of the first mathematical study of heat diffusion, oirginally presented as a paper to the

*Acadmie des Sciences*in 1807. Fourier showed that heat diffusion was subject to simple observable physical constants that could be expressed mathematically. While Galileo and Newton had revolutionized the study of nature by discerning mathematical laws in the movement of solids and fluids, this approach had not been satisfactorily applied to the study of heat before Fourier. His work had major repercussions for the development of both physics and pure mathematics: first, he extended the range of rational mechanics beyond the fields defined in Newton's

*Principia*, establishing an essential branch of modern physics. Secondly, his invention of unprecedentedly powerful mathematical tools for the solution of equations "raised problems in mathematical analysis that motivated much of the leading work in that field for the rest of the century and beyond" (DSB).
