The Building Block of all Matters
Physics can go deeper inside the atomic system and found atomicnuclei and their particle, the nucleons
This structure was first found by Rutherford, who used alpha particleas a probe or microscope in looking for atomic structure
With a simple quantum idea, as λ = h/p, one can probe a smallparticle of side D ' λ/2 (It is the resonance tunneling/scattering.)

Particle Accelerators and Detectors
From the equation of motion of a particle of mass m and charge qunder electromagnetic field
md~v
dt= q
(~E + ~v × ~B
)(1)
One can see that the particle got accelerated by the electric field ~E ,with the energy gain P = q ~E · ~v , and changed direction by themagnetic field ~B, without any energy gain form the field.
People accelerate charged particle with electric field and make achange of particle motion direction by magnetic field

Quark Model of Hadrons
One found that leptons are elementary particles, but
Hadrons compose of quarks
There are 6 flavors of quarks (also 6 flavors of leptons)
