Every human being think the philosophical point of view of the truth that every father sleeps in the heart of a child. Of course, questions about the creation of the world is asking a child to his father now, virtually the same questions his grandfather was raised by his father earlier. Questions can be the same, but the answer is changing day by day due to the development of science and technology. In general, asking the child questions about the same as how the universe began, why the sun rising in the east and west of n sets, the moon why can not find in the night sky, why the stars twinkle in the sky and their explanations are changing day by day because of the improvisation of science. All these things that are related to nature and can be explained scientifically are called Physics, and the means by which the causes of happenings is demonstrated or explained is called physical science.
As physical universe is a vast subject. There are many rivers that are related to physics. For example: price of nuclear physics with particles like atoms, protons, electrons, neutrons and so on. With the help of these particles, it is possible to make a bomb devastating as the atomic bomb causes Hiroshima and Nagasaki in Japan can also be built atomic electric power that can fill the deficit of our future power problem. Astra physics we describe the astrological position of our planet and function of the change of behavior of human beings in their daily lives. Geophysics helps us find the natural resources under the ground or water as crude oil, petroleum products or natural gas, coal and other raw materials of different metals. Biophysics helps us to make different antibiotics and flood resistant crops for cultivation to save people from starvation. Biophysics also helps us to manufacture many life-saving drugs in the pharmaceutical company.
Although physics is vast subject, but since childhood, we learn many things in our physical science course with various events through science projects for kids section. In childhood, we heard the story of the fall of an apple tree. Ordinary people are taking the incident in a normal manner, but Isaac Newton was not an ordinary person, it was a great scientist took the matter seriously and wonder why the apple fell on earth, why not Apple is in heaven? Finally, he concludes, and invented the famous rule: the law of gravitation. This is physics, every moment that you experience something that is related to articles in the field of physics such as health and medicine, Plants & Animals, Mind & Brain, Earth and Climate, Space & Time and matter and energy, but if you are energetic as Isaac Newton and Albert Einstein, then you can also do something for the good of man and the universe.
