The ghost apples are produced on the south shore of Lake Michigan in the United States, and in the winter of 1848 Thomas Lloyd found in his apple orchard, there were no apples on these branches, but the outer outline of the shape of an apple appeared, like the ghost of an apple, so he declared that these apples were both there and not there, as long as people believed that there were indeed apples there, the apples were there, and they could be bought and sold, but because of the natural characteristics of this apple, the purchased apples could not be taken away, because only on his tree, These apples can only be called apples, which are conceptual apples, once they leave his apple tree, these apples no longer meet his definition of apples, so the leaving apples cannot be exchanged for the corresponding value of currency, and later, people can even use the current currency to buy future apples, or use the future apples to exchange the current currency, the apple is not on his apple tree, or how many apples have completely mattered, he only provides a statistically numerical value of how many apples can be produced on each tree , Even the estimate of how many apple trees can theoretically grow per acre of land, the reality is no longer important, only numerical estimates and conversions, as for whether there are apples or apple trees in his apple orchard, no one cares. #ドモヤン #
