“…What made this possible is the availability and use of supercomputers 3 ; the strong coupling between applied mathematicians, computer scientists and the physicists and chemists using DFT methods 4 ; the production and the sharing of the computer codes using DFT by researchers making computations 5 in condensed matter physics, quantum chemistry, material sciences and in nuclear physics; and the needs of the pharmaceutical and chemical industries and companies developing new materials for use in aerospace, computing, building and other applications. 6 The interrelation between the various elements responsible for this dramatic transformation offers an interesting case study in "post-modern" science (Forman 2002(Forman , 2007(Forman , 2010. In Neither Physics nor Chemistry, Gavroglu and Simões stressed the impact of computing on quantum chemistry, and their book ends with a discussion of the 1970 Conference on Computational Support for Theoretical Chemistry (Gavroglu and Simões 2012, 237-243).…”
