・Since neutron without electric charge has the strong magnetic moment, physicists was forced to assume that hadron (proton, neutron) is constituted with smaller element.
・Now, hadron is considered as what consists of six kinds of quarks, and eight kinds of gluons which mediate strong interaction inside hadron.
・There are 3 colorred quarks,red, blue and green, and a white hadron will be formed if the three joins together.
・The word "color" is what imagined the three primary colors of light and was used figuratively.
• It is not possible to retrieve the quark in monochromatic.
・Quark is an energy, there is no form to quark.
・Quarks can be packed in the same place. (Do not follow the Pauli exclusion principle.)
・Quark produce a strong force by replacing the "color" (：Ironi：Bose particles = gluon).
・The force becomes stronger as the distance leaves.
・Placing the electrons of high energy protons, the force is weakened. And Quark is I appear to move.
