Suppose you have a checkerboard and on the first square of that board you placed a single grain of wheat. Then suppose you doubled the grain of wheat with the next square, and the next, and so on until you reached the last one -- the 64th square (in case you've forgotten). Now how much would the entire mass of the board weigh?
If one applies the geometric sum formula we find that the total
number of grains = 1.844674407 * 1019
Therefore the entire board would weigh a whopping 6 * 1014 kg!
The ratio of this weight to the entire human population on the year 2000 would be:
That is the board would outweigh the earth's human population about 14 hundred times!
