So now the nations are like the sand of the seashore. But each grain of sand is actually pretty interesting in its own way.
"A grain of sand, which has a size of about 100 microns, is made up of a million atoms and each atom is about a millionth of a millimeter. Each atom is a universe in its own right. At its center is the nucleus made up of protons and neutrons which is surrounded by a cloud of electrons. 99.9% of its volume is an empty vacuum. There are 92 different kinds of atoms, and these constitute the periodic table of naturally occurring elements."
