The matter’s inertia and interaction in an isolated system
:The intrinsic inertia and interaction of matters with unchanged density in an isolated system are studied. It is shown that the matters have a proved inertia of spin with the angular velocity wn=ddtn=uof isolated system. The conclusive proof can reinforce Newtons the first law, taking into account the non-zero volume of point close to zero without limitation, and can explain the matter wave and seismic waves. A fundamental isolated system with two coupling matters has studied further. The revealed coupling characterizations have been used to explain the DNA structure, Time Cone and topological sphere of moving trace. The proven interaction within two matters is the coupling result of uniform rectilinear motion and spin of isolated system, which may be helpful to uniform the gravitation and electromagnetic force.
