Only Thing That A King Can Not Provide You
Let me tell you a short story. Once upon a
time, there was a wise man who served his king very well. One day the king summoned
the wise man before him and wanted him to ask for a wish as a reward. “Serving your
majesty, is the rewarding itself.” said the wise man. But the king insisted. After a short
time, the chessboard that was in front of the king caught the wise man’s interest. And
he asked only this; Tomorrow, for the first square of your chessboard, give me one grain
of rice. The next day, for the second square, 2 grains of rice. The next day after that,
4 grains of rice. Then the following day, 8 grains for the next square of your chessboard.
Thus, for each square, give me twice the number of the square before it. And so on for every
square of the chessboard. After that, the kings thought about it smiled for a second.
And then he shouted; “Is that all you want? Okay, you’ll get what you asked for.” Next
day, one grain of rice had been sent to the wise man’s house by one of the king’s servants.
And then the second day, 2 grains of rice had been sent. And the third day, 4 grains
of rice. This kept going for a while. 20 days later, the king’s servant realised that 1
million grains of rice should’ve sent. After warning the king about this. They kept delivering
more rice every other day. After thirty days, 1 billion grains of rice had to be sent. But
there was no enough rice in the country. King had to summon back the wise man and ask him
to break the given wish and ask for another thing. The wise man said that he wasn’t asking
for anything. “You insisted, your majesty. It’s enough, I already got what I asked for.”
He said. That amount of rice was actually couldn’t be found even in the entire world.
Let’s make some math now. At the end of 64 days, 2⁶⁴ grains of rice would be required.
And that would be 18 quintillion grains of rice. It seems easy in the beginning, but
as long as the numbers double itself, it grows so fast. Thank you for watching. See you in
the next video.
