Once the law of conservation of energy was well established (see 1847), however, the shining of the Sun had to be questioned.
They sometimes emerged with very little energy, in fact, and some physicists, in despair, felt that the law of conservation of energy simply didn't hold in connection with beta-particle emission.
The law of conservation of energy was thus extended and made more precise by the inclusion of mass as one more form of energy.
Hua Ma, has concluded that, if vector space is having the following symmetry, orthogonality, homogeneity and completeness, it should have three dimensions having the energy obeys the law of conservation and the dynamics law is ruled by the covariance principle and hence we can define the cross product in the space.
