ABSTRACT
You have an unlimited supply of dominoes that measure 1′′ × 2′′ . You are working in a room that is 10 feet long and has no ceiling. You begin at one wall, place a domino on the floor, place another atop it (not necessarily squarely), and proceed to pile dominoes (Figure 11.1). Will your pile be able to reach the other wall, 10 feet away, without toppling?
