MATERIAL WORLD

Figure UNIVERSE

Definition for "Material World" (on the shield: "For matter"):

- We call the material world everything what is made of atomic particles (or what containing atomic particles). Examples of some parts of the material world (of matter in the Universe):

[1] The atoms.

[2] The molecules.

[3] Chemical substances.

[4] The objects (and bodies): solid, liquid, gas or atomic particles.

- The material world is what we receive through the senses.

- The material world we can touch, see, hear, etc.

- Some objects are devoid of life, while others are living beings, but they are all made of matter. Also, our body is matter, but still in life. We are able to touch (tweak) on body, we see on body, etc. Also, the Sun, Moon and starry sky are made of matter. They are called the cosmos. Cosmos and our planet form an entire. It is called UNIVERSE.

- All objects (from the material world) have all the properties continuously changing (in time and space). However, for a time small enough we can consider that (for an object) properties do not change. This is called a state of the object. So, the properties of the objects become from one state to another (in time and space). This is done gradually by continuous accumulation of small amounts of change. If a property (of the object) has accumulated a great deal amount of change, then the man feels the need to put another name for object. Man has an impression: “The object has made a suddenly qualitative leap.”. In this case, the properties (of new object) differ essentially in comparison with the old object.

- For example: We will observe a child. People say "boy". Gradually he is becoming otherwise. He accumulate gradually: Growth, training, payroll, family etc. These accumulations do not permit the name of "boy ". People observe the qualitative leap. They say "mister".
