Quantum Mechanics: The fundamental theory
Quantum Mechanics leads to the fundamental distinction of two types of particles:
Fermions: Particles (like electrons) that can be created or destroyed only in combination with its antiparticle
Bosons: Particles (like photons) that can be created or destroyed in arbitrary numbers
The Fundamental Forces in Nature act between the particles (Fermions) and are carried by Bosons
