ATOM

Atom word came from greek, in greek language atom is atomos which mean can’t be separated again. This is the biggest science mistery, this mistery has been known since 4 B.C. That time, a greek philosopher named Democritrus, told his opinion about material. Democritus said that if a material is divided, it will be the smallest part, which is called atom.

In 1803, a teacher and also a chemist from England named John Dalton, told about the first atom theory, the theory was every materials were built from smallest particles and could not be destroyed, which is called atom.

In 1897, Thomson made a research with a capsule, and he found that there was negative electricity which was smaller than atom. So, the research told that atom was built from electron.

Knowledge keeps expanding through many experiments, not many people know that atom is built from the core of atom and electron cloud. The contain of the core is positive (the contain was built from neutron and proton) and the contain of the electron cloud is negative which always around the core.

Atom is fundamental element. Dalton considered that atom was point particle which couldn’t be separated again, next Thomson found electron, then Rutherford told about atom core and proton, and Chadwick found neutron. So the opinion from Dalton is false.

Proton, electron and neutron are called sub atomic particle, and the smaller particles are called quark and gluon. The behaviour of hundreds of particles can be explained as a combination of fundamental element which is called quark. Before that, only electron is known as one of the fundamental element as a material organizer, in fact quark can be one of the material organizer. All materials are made from quark, baryon combination is a quotation from three quark combinations which are made. Proton and neutron are the examples of baryon. But gluon has a different character than the other particles, they can speak each other.

The universe mistery probably is kept inside sub atomic particle, so an experiment is done. The experiment is shoot two proton particles so they turn around circular tunnel which contain more than 1.000 magnets. Two proton particles will go with a very fast speed almost as fast as light, so can move 11.000 rotation/second, and need thousands magnets with a lot of stamina which the temperature was minus until 2710C.

If atom core split with a sequential reaction can make chaos appear. This could probably be investigation if there were a computer which counting position and atom movement in the universe fast.

Every materials in the universe are known that they were made from atom. Can it be if we could know exactly where are the position and atoms movement in this world, we could a disaster which will happen.

If we could know a disaster which will happen, example tsunami wave and the others. We probably can make the victim just a little or make the amount is smaller and reduce our brothers or sisters’ tears which are falling down to our beautiful earth.
