When we look around us, we see our home, our computer, other gadgets, grass, birds, other human beings, tables, chairs, jungles, soil, clouds, lakes and so on. We see and encounter innumerable creations in our life. Some of them are sold, some liquid and some gases. Some give us comfort while some such as acids burn us. Every object or material has different property, different origin and a different history. An animal shares nothing common with say a tree. But what about the atomic level? How does our world look in the atomic world?
If somebody had the power to see only atomic particles and not a substance he/she would see billion s and billions of nuclei around him/her. They would see innumerable electrons spinning around them. They would find no difference between how they see a human being and an automobile made of steel. How is this so?
Most of us read about atoms in school. Every material is made of atoms. Some of them are only atoms such as silver where as some are molecules such as water. An atom is made of a nuclei and electrons. The nucleus is made of protons and neutrons. The electrons keep rotating about the nucleus without stopping. If you can change the number of protons and electrons in an atom you will be changing the material itself. By changing an atom of hydrogen, you can even get gold. But to break an atom and add or remove protons and electrons is practically impossible.
Though we see the world in form of gases, solids and liquids, the world is made of atoms, which differ only in numbers of protons and electrons. If you can see the world in terms of protons, neutrons and electrons you will find the world to be uniformly made only of these three particles. You will see everything only in terms of particles and see no liquid, gas or solids. If you can break the protons, neutrons and electrons and reach the absolute basic particle that makes these three, you will see only that basic particle. Science has yet to find the basic particle that uniformly makes the whole world.
