Those entries marked * are my favorite papers. For each such paper I have a short note explaining the basic idea, or, in the case of the two theorem provers (NQTHM and ACL2), giving a quick overview of the entire body work on the subject. You may click on the * to see the related note.

*The Role of Human Creativity in Mechanized Verification*, FMCAD 2011 Keynote. Mechanized formal methods aims to automate much of creativity involved in produced mechanically verified artifacts. This talk argues that the tendency to polish our creations -- in engineering, art, or mathematics -- hides the creative process and thus obscures the very thing we, as researchers, should be investigating.*Theorem Proving for Verification -- the Early Days*An informal history of the first 10 years of the Boyer-Moore theorem prover, delivered as a keynote talk at FLoC 2010, Edinburgh, July, 2010.*Mechanized Operational Semantics*five lectures on mechanized operational semantics delivered at the Marktoberdorf 2008 Summer School.*Automated Reasoning and The ACL2 Theorem Proving System*by J Strother Moore and Matt Kaufmann, delivered at the 2006*Visions of Computing Lecture*, Department of Computer Sciences, University of Texas at Austin, November 9, 2006, in celebration of the 2005 ACM Software System Award.*A Mechanized Program Verifier*
