Dear all, During the first weekend of July we will be organizing a session on 'Codifying Knowledge in Early Computer Programming' at the BSHS Annual Conference, Swansea University. The session will count with the participation of Stephanie Dick who will talk about early use of computers in mathematics and logic, Mark Priestley on Von Neumann's attempts to codify knowledge on computer programming, and David Nofre and Edgar Daylight on the role of abstraction in the emergence of computer science. Abstracts and a detailed description of the session can be found at: http://www.bshs.org.uk/conferences/annual-conference/2015-swansea Regards, David Nofre
