Take an 8x8 sheet of gold and cut it into pieces as in Figure 1.


Figure 1: 8x8 sheet of gold, total area is 64.

Then rearrange the pieces as in Figure 2.


Figure 2: 5x13 sheet of gold, total area 65.

You have now profited 1x1 square of gold. This method was suggested by epistemological research of L. Peikoff and perfected by A. Greenspan.)
