The Leverhulme Trust have recently made a major award to myself and my collaborator Prof Elizabeth Scott which we will use to document, formalise and implement simulators for Babbage's Notation. The team also includes Plan 28’s Dr Doron Swade, who is the foremost authority on Babbage, and Dr Piers Plummer who has an extensive background in chip design, computer architecture, mechanical CAD and programming language compiler design. The work will be based in Royal Holloway's Centre for Software Language Engineering.<br></blockquote><snip><br><br>Full article at <a href="http://blog.plan28.org/2014/11/babbages-language-of-thought.html">http://blog.plan28.org/2014/11/babbages-language-of-thought.html</a><br><br>Cheers<br><br>Brian Randell<br><br><br>School of Computing Science, Newcastle University, Newcastle upon Tyne, NE1 7RU<br>EMAIL = <a href="mailto:Brian.Randell@ncl.ac.uk">Brian.Randell@ncl.ac.uk</a> PHONE = +44 191 208 7923<br>URL = <a href="http://www.ncl.ac.uk/computing/staff/profile/brian.randell">http://www.ncl.ac.uk/computing/staff/profile/brian.randell</a><br><br><br>_______________________________________________<br>This email is relayed from <a href="mailto:members@sigcis.org">members@sigcis.org</a>, the email discussion list of SHOT SIGCIS.
