The Standard Model chart contains 12 fermions, 4 bosons, and 1 Higgs Boson.
In the Standard Model Chart the 12 fermions that make up observable matter are comprised of two types: quarks and leptons.
Quarks (6)
Quarks make up the nucleons of atoms. These are the particles at the center of an atom. Nucleons are further subdivided into 2 types: Up quarks and Down quarks (top/bottom and charm/strange quarks in the 2nd and 3rd generations).
Leptons (6)
Leptons are comprised of electrons (and electron neutrinos). These are the particles found outside of the nucleus and are exchanged between atoms to form molecular bonds.
Duality Balance & Symmetry
Within the model we can see a recurring duality in the expression of matter. Each particle, subgroup or category seems to be further divisible into two complimentary components.
Fermions > Quarks Leptons
Nucleons > Protons Neutrons
Quarks > Up Down, Top Bottom, Charm Strange
This duality can be seen on the quantum level in the "particle-wave duality" observed in quantum mechanics (i.e.. double-slit experiment )
This apparent duality inherent in nature will help us understand the Standard Model - it will also be referenced heavily within the African cosmological models we study.
