FUNDAMENTAL PARTICLES

CONTINUED FROM: INTRODUCTION TO FUNDAMENTAL PARTICLES

Nice and simple introduction right? Now lets go down to business. What do we mean by Fundamental particles?

Fundamental Particles can be defined as the smallest, indivisible particles that forms matter and determines their properties and interaction with other matters

(Sounding more like the earlier definition of atoms right? haha)

Anyway, fundamental particles are divided into two groups, namely;
1) The Fermions, and
2) The Boson.

Let's discuss briefly on these two groups before we 'delve' into them fully.

FERMIONS (Matter Forming Particles)
Fermions are like the 'building blocks' of matter. They come together by the help of force carrying particles to make matter.

Fermions are the building blocks of matter.

The Spin of Fermions are always half-integer spins like 1/2, 3/2, 5/2, etc; this makes them able to obey;

a) the Fermi-Dirac Statistics: which in Physics, is the branch of quantum statistics used to calculate the permitted energy arrangements of the particles in a system in terms of the exclusion principle (thefreedictionary.com, 2013), and
b) the Pauli's Exclusion Principle: the quantum mechanical principle which states that no two identical fermions may occupy the same quantum state at the same time (Wikipedia.org, 2013)

BOSONS (Force Carrying Particles)
While fermions as the building blocks, bosons are the 'cementing agents' that holds them together as I mentioned earlier.

Bosons holds matter together.

Bosons were first theorized even before they were observed and even one of them, the graviton, is yet to be observed.
Fermions interacted with each other by exchanging force carrying particles with one another. These force carrying particles are of different natures and strengths and are peculiar to a given type of force.
Bosons have integer spins like 0, 1, 2, 3, etc; and hence they obey;
a) Bose-Einstein Statistics: a version of fermi-dirac statistics that applies to boson.

Note: that the use of the phrase 'cementing agents' to describe bosons does not mean that all of them are as strong as cements. It was used to create a close-enough mental picture.

On my next article, we would go deep into... YOU CHOOSE:
FERMIONS or BOSONS.
