Renaissance-man, Leonardo Da Vinci, observed air bubbles slowly ascending upwards. He noticed those bubbles did not rise up to the surface directly, but some were travelling willy-nilly.
If you take a glass and fill it with seltzer, you will notice the exact same thing.

But, who actually pays attention to something like that?

Bubbles can travel in a particular trajectory towards new paths which may be unstable due to interactions taking place in the water, depending on the fragile nature of their shape.

This trajectory plays a significant part in our lives, as it explains many natural phenomena, from petrochemicals to our surroundings.

As such, as within quantum mechanics, the notion of uncertainty comes to play and what does it tell us, humans? That everything is predictable, but at the same time prone to malfunction or even be sabotaged, such as when an action is being done to better the world in the process.

Uncertainty, as hard as it may be or surprisingly good (or bad), is everywhere in the balance of the world which has to abide by the rules of nature for it to prevail, and for us to understand that there is no such thing as "betterment", as the action may become the complete opposite of it, so are our lives, complicated as they may be, in which the outcome may not be desirable.

But what do we have to do with these rules of nature?

The Old Testament shows this to us everything, and though it may seem Man was going in the right path, it turned out to be the complete opposite of it.

For example, Moses and God have a "love story" in which they have met and spoken face to face, but Moses was then dethroned and replaced with a non-experienced leader, such as Joshua. This was a surprising tale, considering the fact Moses was chosen by God to lead the Hebrews out of Egypt and into The Promised Land.

Even the tale of Saul, the first king of Israel who unified the tribes into a single entity, and fought bravely against its enemies, met with his unfortunate demise. In his place, rose a new king.

Such is the Rule of Uncertainty.
