Rain.

Even the word itself, the phonetic sound, is soothing and brings a sense of relaxation to the mind. It's water falling from the sky, after all; water, the bringer and maintainer of life, falling from the clouds above. It's quite the miracle. The whole cycle is miraculous. To think, that in order to maintain the life on this planet, everything hinges on water being able to evaporate into clouds, and then once those clouds are "full," being able to condensate and fall to the ground, only to repeat the process over and over, for the billions of years that the Earth has been here.

If you look more closely, that miracle hinges on the molecular structure of water. On a level most people despise their chemistry professors for teaching them, two hydrogen atoms bond to an oxygen atom, at a very exact angle. You have two hydrogen atoms for every oxygen atom to satisfy oxygen's need to be electrically neutral. This gives water a unique shape, but the fact that the hydrogen atoms can so easily stick to oxygen atoms in other water molecules is what makes the whole shabang work. Without this concept of "hydrogen bonding," you'd have no liquid water on this planet. Without liquid water, nothing would be alive today. There would have been no universal solvent billions of years ago to allow the formation of life from inorganic molecules, and there'd be no universal solvent today to allow anything from the dissolution of nutrients in your blood to the existence of lemonade.

It sounds like a science lesson, doesn't it? I'm sorry. But look at the precise beauty of it all. Everything has come together so amazingly, so precisely, that one has to recognize this beauty at least once in their life when they stare out over the ocean, or watch rain fall from the sky, or draw their bathwater. Without these basic, teeny-tiny quantum principles on which the hydrogen and oxygen are built, you wouldn't have water. Without water, you wouldn't have the water cycle. Without the water cycle, there'd be no life. And without life, there would be no one around to contemplate the droplets of water on a leaf. Things in this world are always made up of smaller and smaller details, but you can step back from those details, and examine the brilliance of the big picture, too.
