From a Caterpillar to a Butterfly
If you had 450-500 eggs and if you had to preserve them outside, what would you do? The wisest course for you would be to take precautions to prevent them from being scattered around, say, by the wind, or other environmental factors. Being one of the animals that lay the most eggs at one time (450-500), the silkworms use a very intelligent way to protect their eggs: they unite the eggs with a viscous substance (thread) they secrete to prevent them from being scattered around.
The caterpillars that pop out of their eggs firstly find a safe branch for themselves and then get tied to this branch with the same thread. Later, to promote their own development, they start to spin a cocoon for themselves with the thread they secrete. It takes 3-4 days for a caterpillar that has opened its eyes very recently to life to complete this process. During this period, the caterpillar makes thousands of turns and produces a thread an average of 900-1,500 metres long. At the end of this process, it starts a new task through which it undergoes a metamorphosis to become an elegant butterfly.
Neither the action taken by the mother silkworm to protect its eggs, nor the behaviour of a tiny caterpillar devoid of any awareness, education or knowledge can be explained by evolution. First of all, the ability of the mother to produce the thread it uses to secure its eggs is miraculous. The newly-born caterpillar's knowing the most suitable environment for itself, its spinning a cocoon in accordance with it, its undergoing a metamorphosis, and its coming through this metamorphosis without any problem are beyond human comprehension. Hence, we can simply say that each caterpillar is born into the world with a foreknowledge of what to do, which means that it was 'taught' all of these things before it was born.
Let us explain this with an example. What would you think if you saw a new-born baby standing up a few hours after his birth, getting together the things he needs to make his bed (like quilt, pillow, mattress), and later putting all these together neatly, making his bed and lying down on it? After you recover from the shock of the event, you would probably think that the baby must have been taught in an extraordinary way in his mother's womb to perform such a process. The case of the caterpillars is no different from the baby in this example.
This again leads us to the same conclusions: these living creatures come into life, behave and live in the way determined by God Who has created them. The Qur'anic verse stating that God has inspired the honeybee and commanded it to make honey (Surat an-Nahl, 68-69) provides an example of the great secret of the world of living beings. This secret is that all living beings have bowed to God's will and follow the fate determined by Him. This is why the honeybee makes honey and the silkworm produces silk.
THE SYMMETRY İN WİNGS
When we look at the butterfly wings in the pictures, we see a perfect symmetry prevailing over them. These lace-like wings are so adorned with patterns, spots and colours that each of them is like a work of art.
When you look at the wings of these butterflies, you notice that the patterns and colours on both sides are fully identical, no matter how intricate they may seem. Even the smallest dot is present on both wings, thereby introducing a flawless order and symmetry.
In addition, none of the colours on these thin wings mixes with the other, each being sharply set apart from the other. Actually, these colours are formed by the amassing of tiny scales clustered one on top of another. Isn't it a wonder how these small scales that are easily dispersed with your hand's slightest touch can be arranged in both wings without any mistake in their disposal so as to produce exactly the same pattern. Even the replacement of a single scale would destroy the symmetry in the wings and impair their aesthetics. However, you never see any muddle in the wings of any butterfly on the earth. They are as neat and elegant as if made by an artist. And they are indeed made by an Exalted Creator.

Loro jonggrang
Loro jonggrang was the daughther of a giant king callet Ratu Baka.She had a proposal from a young noble,Bandung Bandawasa.He was handsome wealthy,and powerful, but Loro Jonggrang didn”t want to merry him. Ratu Baka gave a task to Bandung Bandawasa. He had to make 1,000 templesin one night, to prepare his marriage to Loro Jonggrang.
Bandung Bandawasa used his supernatural power call the genies, and they made the temples in unbelieveable speed.Loro Jonggrang saw that the task was almost complete.Then,she ordered her servants to help her hit the rice puncher,and made the sound of cooking. These actions would make the genies think that morning had come. They would run away. Bandung Bandawasa was angry with Loro Jonggrang. He already finished 999 temples,and when he built the 1,000th, he cursed Loro Jonggrang into a stone statue to fill in the 1,000th temple.
Once there was a mountain. She stood strong and proud.She was covered with huge trees.Bees made their hives high on the branches too.Ferns and creepers grew on the trees.The air was cool and pure.The rain brought fresh water. The water was clean and clear . The rivers and waterfells had their homes here.The rivers were full of fish.
The forest people livet on the fist and the plants found there. They used the water from the river for drinking,washing their clothes, and for watering their crops.All was peaceful on the mountain.
Then some people came from the city. They saw the great mountain and her beautiful green crown.
“What large trees! Let”s cut them down and use the wood to build our houses and bridges,” they said.
Hurriedly,they came with their saws and machines to cut down the trees.
The monkys and birds screamed.
“They”re taking away our homes! Leave us alone,please,” they cried.However,the greedy people did not hear them. Soon, the sides of the mountain were bare.When the heavy rains came,the soil loosened and flowed into the rivers. It blocked the river mouths.The rivers became muddy and dirty.The fish in the rivers died.The forest people came to fish.However,they went home sad and empty-handed.They asked the mountain,”What has happened to our lovely trees and clear rivers?”The mountain hung her head sadly.

Development Of Atomic Model
beginning of the development of atomic models and hypotheses, along with his developing science and technology.
the term originated from the atomic era, and Democritus leukipus which states that the smallest objects are atoms. derived from a Greek word that means divided
new in the year 1803, John Dalton put forward his opinion about the atom, as follows:
a. attitude element is composed of tiny particles that can not be divided again that called atoms.
b. atoms of the same element will have the same properties are not the atoms of different elements will have different properties.
c. in a chemical reaction there are no missing atoms, but only changes the composition of atoms in the substance.
thomsom concluded that the atom is a solid ball in it that positof spread negatively charged electrons. his subsequent trial in fact done by Rutherford concluded that atoms consist of nuclei is very small and positively charged
Rutherford opinion is contrary to Maxwell's theory of mechanics which states that if there is a charged particle moving mlingkar be lost
loss of energy, so that the electrons moving.
weakness of the Rutherford atom model was improved by Niels Bohr.
Bohr said that for the electrons surrounding the atomic nucleus loses energy and does not differ in levels of certain energy called the electron orbits or skin.
Warner heisenbeng discovery shows that the Bohr atom model no longer appropriate with Erwin Schrödinger. heisenbeng proposed model of the atom more familiar with the atomic model of the atom wave mechanics or the modern atomic model.
there are some elements of nature, such as
1. atomic radius
a. the number of electron shells
b. nucleus charge
2. ionization energy
ionization energy is the energy required to release electrons.
3. electron affinity
