#2“HOW MANY GRAINS OF SAND ON THE EARTH?”
Mathematician Marcus du Sautoy, author of The Number Mysteries (Fourth Estate), says that sand is rock with a diameter of between 0. 625mm and 0. 2mm.
Assuming a grain of sand is roughly spherical, the average volume of a grain is 4/3 x pi x r3=0. 00947mm3, where r is the radius.
So how many grains of sand are there in a metre cube box?
It has 109mm cubes inside (10N is how mathematicians write a 1 followed by N zeros), and if they are arranged randomly, about 65% of the box will be sand and the rest air.
So we can estimate that the number of grains of sand in a metre cube box is 109 x 0. 65/0. 00947, or roughly 70bn grains.
Now, let’s go for an average of 5% of the surface of the Earth being covered in sand with a depth of 100m.
The surface area of the Earth is 4 x pi x r2 where r is the radius of the Earth, which is 6,378,000 metres.
So the volume of sand comes out at: 2. 5 x 1015m3.
So the rough estimate is that the number of grains of sand on the Earth is a number with 27 digits … that is …
1, 000, 000, 000, 000, 000, 000, 000, 000, 000
Now lets suppose you could place a number on each grain and had a lottery for picking the winning grain.
“And now …. Ladies and Gentlemen … the winning number is 973, 251, 684, 342, 701”
Dear Reader would you be having a bet in this lottery? HARDLY!
But you’re betting your soul … an eternity in hell … against the odds of a DNA strand by evolution with a number of 40,000 digits!
Methinks only the certified insane would take these odds … WHAT SAY YE?
“Look Preacher, you’re just trying to scare me about burning in hell!”
“Yes I am … you’re absolutely correct!”
