A week-end off: the first extensive number-theoretical computation on the ENIAC

The first extensive number-theoretical computation run on the ENIAC, is reconstructed. The problem, computing the exponent of 2 modulo a prime, was set up on the ENIAC during a week-end in July 1946 by the number-theorist D.H. Lehmer, with help from his wife Emma and John Mauchly. Important aspects of the ENIAC's design are presented-and the reconstruction of the implementation of the problem on the ENIAC is discussed in its salient points

Setting-up early computer programs: D. H. Lehmer's ENIAC computation

A complete reconstruction of Lehmer's ENIAC set-up for computing the exponents of p modulo two is given. This program served as an early test program for the ENIAC (1946). The reconstruction illustrates the difficulties of early programmers to find a way between a man operated and a machine operated computation. These difficulties concern both the content level (the algorithm) and the formal level (the logic of sequencing operations)

The Archival Book as an Experimental Dialogue in Public History

This article argues for a new genre of book making which I call an archival book that is created to present archival material to the public. The book discussed here was published as a commemorative volume in 2010, soon after the centenary of the Indian physicist, Homi Bhabha. The archival book described here attempted to move away from the celebratory coffee table format and focused instead on the archives of the scientist. The article tries to define the key characteristics of the archival book that is meant for the public and not exclusively for a scholarly community and the challenges of presenting archival material in this form. Finally, the article focuses the inter-disciplinary nature of the archival book-making project and the collaborative way in which the writers and designer can work together in order to make the archives accessible, especially in countries where archives remain inaccessible to the general public
