Inspired by the following passage in the book “A Short History of Nearly Everything” by Bill Bryson:

The basic working arrangement of atoms is the molecule… A molecule is simply two or more atoms working together in a more or less stable arrangement: add two atoms of hydrogen to one of oxygen and you have a molecule of water…
At sea level, at a temperature of 0 degrees Celcius, one cubic centimetre of air (that is, a space about the size of a sugar cube) will contain 45 billion billion molecules. And they are in every cubic centimetre you see around you…
Above all, atoms are tiny – very tiny indeed. Half a million of them lined up shoulder to shoulder could hide behind a human hair. On such a scale an individual atom is essentially impossible to imagine, but we can of course try.
Start with a millimetre, which is a line this long: -. Now imagine that line divided into a thousand equal widths. Each of those widths is a micron. This is the scale of microorganisms…To get down to the scale of atoms, you would need to take each one of those micron slices and shave it into ten thousand finer widths. That’s the scale of an atom: one ten-millionth of a millimetre…One atom is to that millimetre line above as the thickness of a sheet of paper is to the heigth of the Empire State Building."
The visible natural world fills me with wonder every single day. It inspires me, fills me with joy and peace and wonder. The invisible natural world fascinates me too. It fills me with amazement and shows me how much more to the world there is than meets the eye. It makes me think of this wonderful saying:
“To a worm in horseradish the world is horseradish”.
