The subjects are arranged such that they go around in a circle and come back to physics, where religion is the worship of physics. In a sense, religion is emotional physics or feeling physics for physics is the ultimate truth and God is one atom of 231Pu. And so, the emotions or feelings of love and hate, I feel, need be addressed with a file. It is not as hard as what most scientists would think. In fact it is rather easy to pioneer the science of love and hate.
Love is the general concept of joining together or union of separate parts or the bringing together.
That is the easy part about love and hate. Now the hard parts come in. Love and hate are not simple linear concepts but are complex nonlinear concepts. The two come together. And the best analogy for this is the physics of particle and wave.
