  Euclidean geometry does not characterize dynamic electronic orbitals
satisfactorily for even a single electron in a hydrogen atom is a formidable
mathematical task with the Schrodinger equation. Here the author puts forward a
new spacetime concept that regards space and time as two orthogonal, symmetric
and complementary quantities. They are inherent physical quantities that cannot
be divorced from physical objects themselves. In two-dimensional helium shell,
space and time are instantiated by two interactive 1s electrons; in
four-dimensional neon shell, space and time dimensions blend into four types of
curvilinear vectors represented by 2s, 2px, 2py, and 2pz electronic orbitals.
The description of electronic orbitals constitutes an explanation of canonical
spacetime properties such as harmonic oscillation, electromagnetism, and wave
propagation. Through differential and integral operations, the author
formulates a precise wavefunction for every electron in an inert neon atom
where spacetime, as dimensional graduated by ten electrons, is continuous, and
trigonometric function is the mechanism for dimension curling up. This fresh
spacetime view based on dimensional interpretation of complex functions is an
extension of classical mechanics and is compatible with relativity and quantum
physics. It brings sharp insight into the geometries of 2p-orbitals and has
broad support from chemistry.
