1) Particles: Prologue

Hi guys!
I am back with probably short post because I am lazy and tired these days. I know I wanted to start something about triangles but right now I am not that excited for it so I will make some posts about particles. I talked about some before but I have never explained what the hell are quarks for example.

So first of all… particles. Well we think about them like small stuff that is everywhere and everything is made up of it. That is right.
So I will start with molecules, easy peasy those are just two or more atoms made up together.
Atoms are (small), there is some stuff in them but first of all there are “kinds” of atoms, substances and that is Hydrogen, Helium, Oxygen, Carbon. They are made up all from the same things but with different amounts. Atoms are made up of core and shell. Usually, you wont do anything with core. It is very stable and not interacting. In our organism there are only changes in molecules. That means that some atoms will move somewhere else and that will change molecules properties.
Shell is made up of electrons. Electrons are NOT made up of something else, it is just primal stuff. Electron belongs to group of particles that are called elementary particles. It´s sub-group is called fermions and its sub-sub-group is leptons which are really small and light.
Core is made up of neutrons and protons. As I talked about them in four fundamental forces series those are particles (sub-atomic) that are hold together by strong force. Anyway protons are positive and neutrons neutral.
There is huge experiment going on in Japanese which is trying to proof that protons are decaying. Its problem is that one proton has half time about 10^31 years long. They did nice trick so they do not need to wait so long by monitoring ultra clear water. There are thousands tons of water and their machines are able to detect any proton decaying to photons.
Photons are also elemental particles but their sub-group is special for particles that are carriers for fundamental force: photon, gluon, bosons but not graviton because he is only hypothetical. Photons are massless which is why they can travel at the speed of light.
At last for review there are quarks which are elemental particles, even fermions like electrons but they are in special group for quarks.
I actually read something about quarks not being elemental (only hypothetical). It was said that if they are not elemental we can not be sure that there is unlimited number of smaller and smaller particles.

This was just a short preview of what I will write about next time.
