The Legend of the Chess Board and the grain of Rice

 Chessboard and a grain of rice

This legend of the chess board and the grain of rice cannot be historically confirmed and comes in many variations. One such version is that the Emperor asked the man what he would like to receive for this fantastic new game of tactics, strategy and planning. As the story goes the inventor chose for a grain of rice to be placed on the first square of the board and that amount doubled for the second and in turn that quantity multiplied by two on the third square until all sixty-four squares were paid out in full.

 

This tale, be it factual or not, is often used by mathematicians to explain the concept of exponential growth. It is difficult to fathom that by using this simple formula the accumulative amount is 18,446,744,073,709,551,615 grains of rice, and that in only 64 steps.

 

How much is that? 

1,000,000         Million 

1,000,000,000              Billion 

1,000,000,000,000                   Trillion 

1,000,000,000,000,000                        Quadrillion 

1,000,000,000,000,000,000                             Quintillion 

1,000,000,000,000,000,000,000                                  Sextillion 

 

Let’s put the same concept into another practical example. Imagine one person had to write down the name of only two people he or she knows and every one of those people had to do the same, but no name or person may be used twice or be duplicated.

 

By comparing this exercise with the above analogy of the rice grain on the chess board, it quickly becomes evident that there are simply not even nearly enough people in the entire world to complete the task.

 

The baffling concept of exponential growth in the speed in which the number of units increase from level to level is also commonly used in Multi Level marketing and Pyramid Scheme models. In these instances the concept of the chess board and grain of rice analogy is often used to demonstrate the money making potential of the system and the pure unlikelihood of running out of new recruits or participants into the system.

 

It is, however, the same chess board and grain of rice analogy described above that proves that any pyramid scheme is destined to collapse as there are not nearly enough people in any single area to sustain the exponential duplication over a significant period.
