There is an old story about fission, which is about Shehanwang in India. One day, She Hanwang intends to reward the inventor and tribute of chess (that is, chess, which consists of 64 small squares)-Prime Minister Shisha Bandal. The wise minister seems to have little appetite. He knelt before the king and said, "Your Majesty, please give me one grain of wheat in the first grid, two grains in the second grid, four grains in the third grid, and so on. Each compartment is twice as big as the previous one. Your Majesty, please give all 64 tablets on the chessboard to the liegeman! " "Well, love qing, it seems that you don't meddle! That's settled. " The king said, but he was secretly pleased that he had wisely and generously rewarded this wonderful invention. Then he ordered a bag of wheat to be brought to the throne.

The work of counting wheat grains has begun. The first compartment is one grain, and the second compartment is two grains ... Before the twentieth carriage, the bag was empty. With the increase of lattice, the number of wheat grains increased dramatically. It is not enough to see bags of wheat used up. At this time, she Hanwang was dumbfounded, and even if she brought all the food in India, she could not fulfill her promise. Because this is an equal proportion series (which will be discussed in high school mathematics), according to this calculation, you should put 18, 446, 744, 073, 709, 55 1, 6 15 in 64 squares of the chessboard. This number doesn't look too big. In fact, 1 m3 contains about 1 5 million grains of wheat, and the volume of wheat required by Xisha is about1200 cubic kilometers. In fact, the sum of all the wheat produced in the world in a year has not reached this figure.

In this way, She Hanwang found herself in debt to the Prime Minister. He either put up with the Prime Minister's endless debt collection or simply cut off his head. My guess is that the king probably chose the latter method.

The king didn't understand that fission equals exponential growth, so he was taxed on IQ.
