Finally! I finally found a passing reference to what I've been calling "Grover's Law". I even blogged about it in 2007. In all that time I have never been corrected or pointed to a similar law. That changed tonight.
If in any problem you find yourself doing an immense amount of work, the answer can be obtained by simple inspection.
That sure sounds like what I've been calling Grover's Law. And it is just sooooo fitting that it is considered (by some apparently) a part of Murphy's Law. So now I can give credit where it is due. Thank you Murphy!!
