The Goldbach Conjecture is still unsolved?  That can't be right.  I 
nailed that one in middle school, as the rule was stated right there 
in my textbook, so it must be true.  :-)

As for Hermione's age, I still haven't heard a satisfactory 
explanation as to why I should wrap my mind around that one.
