Of Castles And Kings (chess)

Castles and King Chess, which are thought to be born in India, have undergone a long way as it is the earliest record, probably the history of violence. Due to its origins, chess has undergone several changes. One of the biggest changes in chess is the transition from a classical opening to a new style called ultra modern openness. Before understanding this change, you must understand the history, rules, and strategies of chess. There are many theories about the origins of chess. The most popular idea is that it comes from the Chaturanga game, which was once considered a Chinese checker, but it is now considered to be of Indian origins (from India, from the country).

The king is a chess enthusiast and is accustomed to challenging the wise to participate in the chess competition. One day, the saint of the trip was challenged by the king. In order to motivate his opponent, the king offers any reward that a saint can name. The wise person humbly requests several grains of rice as follows. The king puts grains of rice in the first chess square and then adds 1 meter to each. As the index of payment of rice increased, the king immediately noticed that he could not fulfill his promise, for the 20 th square the king had to invest 1 million rice of rice I guess. In the 40th square the king will have to invest 1 billion rice of rice. And finally, in the 64th square, the king will have to place more than 18 trillion tons of rice, which is enough to cover the entire territory of India, 1 meter thick rice.

The game of chess started, not to mention the king lost the game. It is time to pay the saint the bonus that he agreed. When he began adding rice grains to the chess board, the king quickly recognized the essence of the saint's request. In the twentieth square, this number reached 1 million grains, and by the 40th square it became 1 trillion grain. The royal granary soon ran out of rice. The king noticed that he could never respect the promised promise even if he provided all his rice in his kingdom and neighboring kingdom. The number of grains in the age group has increased and the total amount of rice needed to fill the 64 square board is 264-1, which is equivalent to 18,446,744,073,709,551,615 (about 18 x 10 18, or 18 billion). The weight of this meter is about 460 × 10 12 kg, or 460 kg (petogram), or 46 billion tons (assuming 1000 particles of rice weigh about 25 grams).

The story that is said to have started in Persia provides a classic example of exponential growth. It asked the smart courtier to give the king a beautiful chess, then ask the king to give 1 grain, 2 or 2 times, the second square, 4 to the first square in the grain (or double) 3 It is the th th thing. The king did not agree mathematically and agreed to take out the rice from the storehouse. The eighth square requires 128 grids and the 12th square requires more than 1 pound. Every crop of the kingdom was used long before it reached the 64th open space. Even today, the world 's total rice production is not enough to meet the board' s final square requirement.
