Reality and the world of 3D - Part 07

Reality - Continued 6

Let's continue our discussion of water and fluids.

When water(or any liquid, for that matter) flows, it does so in a particular manner. The flow isn't even, it breaks up on the sides and splashes, it coallesces when it hits a deep pool of liquid. It also makes a noise that is unmistakable.

What else can we think that water does? It drips. Watch it some time. Take a beaker of water and slowly, very very slowly let it pour out. Watch the water drops form on the tip of it, then break off and fall to the ground. For now, that's enough discussion about water movement.

Let's now talk about how water affects objects around it, and objects that are in it.

Splash some water on a stone and what happens? It gets somewhat brighter, and becomes more reflective, in the areas covered by water. This changes when the object dries and the water evaporates. Once that happens, spots may be left on the object where the water touched it.

Waves on water have a distinct pattern and work in certain ways. There may be mist in the air(mist is another way of saying that an amount of water has broken up into really tiny particles). When waves hit an solid object, they break and foam is formed in some cases, especially when the waves land on the beach.

Depending on the type water you're looking at, the surface may be relatively reflective and refractive. The reflection and refraction will not be smooth, but will follow the contours of the waves.

Under the surface, water may contain a large quantity of particulates like dust, air bubbles and small marine animals. Light from the surface may be refracted, and in many cases, especially oceans and lakes, you can actually see light itself in the water.

For now, we're finished with objects. In the next section, we will look at forces that act on the objects around us. Please stay tuned...
