Absurd, complicated, chaotic, harmonius.
The world is absurd, because a lot of the laws of physics we have discovered are absurd; Things like the Double-slit experiment just make no sense in the common sense kind of way. Yet we see the world to be such: absurd and stranger than we can suppose.
Complicated. While even in Newtonian systems we have high predictability to an extremely high degree, these calculations get increasingly complex as we begin to take more and more factors into account. Trillions of sub-atomic particles are colliding within ourselves at any given moment and a few billion pass through us every second without any effect whatsoever. We ourselves are based on a fairly complicated balance of chemicals. Yet this all began from relatively simple beginnings. That is the nature of the universe: simple things become complex as time passes.
Chaotic. Due to the ever-changing nature of the world around us, no system of any but the smallest scales has true predictability. No two experiments are ever exactly alike, the results are simply close enough that it does not matter or our instruments cannot detect the difference. Yet the difference is there. Since it is impossible to take every variable into account, the world experiences chaotic behavior: we can predict things only into a degree of certainty. After all, it has been said that a butterfly in china flapping it wings affects the direction of a hurricane on the Pacific. And this is true.
Harmonius. Despite the apparent chaotic nature of the world, the forces that guide it are in harmony. These laws, when left alone in even simple systems, produce complexity. Even as you take a glass of water from the tap, water is being broken into hydrogen and oxygen in minute amounts. Naturally molecules almost instantly recombine back to water. But the system is still dynamic, in an equilibrium that fits the surroundings. If we change the surroundings, the equilibrium changes. Add heat and more water molecules will evaporate. Reduce heat and more water molecules will begin to condensate on the glass. Remove heat more and the water begins to freeze. This apples to all thermodynamic systems: The system, by the nature of the laws tha govern it, reaches an equilibrium if given enough time. And whereever there is heat, there a thermodynamic system. From the smalles to the largest scale, nature is constantly striving towards equilibrium, balance. And that is harmony.
