I came across something in a very different context that struck me as a fitting end to this particular blog thread.
A sign posted in a laboratory reads as follows:
Theory is when you know everything but nothing works.http://medicalhumour.wordpress.com/c...ratory/page/3/
Practice is when everything works but no one knows why.
In our lab, theory and practice are combined: nothing works and no one knows why.
Here endeth the thread.
P.S. I'm continuing to post, in a more hopeful vein, in the thread titled "A Skeptic's Delight".
