"You have to budget the number of fuzzy rules you use to control a system. It turns out, you can state the optimality principle in three words: 'patch the bumps.'"
- Bart Kosko

Memory Hole  
  A receptacle for unwanted documents.  

In the walls of the cubicle there were three orifices... in the side wall, within easy reach of Winston's arm, a large oblong slit protected by a wire grating. This last was for the disposal of waste paper. Similar slits existed in thousands or tens of thousands throughout the building, not only in every room but at short intervals in every corridor. For some reason they were nicknamed memory holes. When one knew that any document was due for destruction, or even when one saw a scrap of waste paper lying about, it was an automatic action to lift the flap of the nearest memory hold and drop it in, whereupon it would be whirled away on a current of warm air to the enormous furnaces which were hidden somewhere in the recesses of the building.
From 1984, by George Orwell.
Published by Unknown in 1948
