I think that theorem-proving, as an application, excels in terms of
"clearly-defined results" but not so much in terms of "potential
However, I do know of one commercial application of theorem-proving. My
former colleague Deepak Kapur used his (fairly simplistic) automated
theorem proving software to formally prove the correctness of some of

An example paper title from his site is:
--- Theorem Proving Support for Hardware Verification Deepak Kapur Invited Talk, Third Intl. Workshop on First-Order Theorem Proving, FTP 2000 St. Andrews, Scotland, July 2000. --- Needless to say, that sorta thing is a lot easier than proving the Riemann hypothesis! In general, "proving program correctness" is of interest to a lot of people in the software industry, especially in the military where reliability is considered critical. For instance, some people use the Z specification language to formalize software designs: one then has a problem of efficiently proving a complex software design, formalized in Z, is correct. There are also variants like Object-Z (or something like that .. I haven't studied this stuff for a while). Among well-known theorem provers, I like Otter http://www-unix.mcs.anl.gov/AR/otter/ because it uses combinatory logic, which is related to the knowledge representation inside Novamente. However, the results obtained with Otter or any other theorem-provers to date are far, far short of prove-the-Riemann-hypothesis level! A review of Otter and some other contemporary systems is here: http://www-users.cs.umn.edu/~dliang/CSci8980/Projects/TheoremProvers.htm The TPTP problem set http://www.cs.jcu.edu.au/~tptp/ is a standard collection of theorem-proving problems for automated theorem-provers....
