Finite element methods were used very successfully by engineers long before Strang and Fix wrote the book. The history of mathematics when written by an unbiased observer surely intertwines with all human endeavros. A few quotes come to mind: "Mathematics: may it never be of any use to anyone!" Henry John Stephen Smith, 1826 - 1883. "The deep significance of certain problems for the advance of mathematical science in general and the important role which they play in the work of the individual investigator are not to be denied. As long as a branch of science offers an abundance of problems, so long it is alive; a lack of problems foreshadows extinction or the cessation of independent development. Just as every human undertaking pursues certain objects, so also mathematical research requires its problems. It is by the solution of problems that the investigator tests the temper of his steel; he finds new methods and new outlooks, and gains a wider and freer horizon." David Hilbert, {\em Bull AMS}. {\bf 8}. 102, 437--479. "As mathematics travels far from its empirical source, or still more, if it is a second and third generation only indirectly inspired by ideas coming from ``reality,'' it is beset with very grave dangers. It becomes more and more purely aestheticizing, more and more purely {\em l'art pour l'art}. .... In other words, at a great distance from its empirical source, or after much ``abstract'' inbreeding, a mathematical subject is in danger of degeneration. At the inception the style is usually classical; when it shows signs of becoming baroque, then the danger signal is up.''. J. von Neuman (1943. ``The Mathematician.'' In *In the Works of the Mind.* Chicago, IL: University of Chicago.) Best regards, steve ----- Steve (really "D. E.")
