The appearances and textures of this world are defined by electron shells. It might be safe to say, that atoms are the most awesome invention this universe has ever seen. Electrons are time forward entities. Time forward means negative charge. The emission of light from a bulb or TV screen, etc. is a non reversible exchange of energy represented by electrons.
Wristwatches count electron pulses.
And so on. There will be seeming exceptions to this, but upon consideration I have seen them all end up back at the electron level at the detection process. Time reversed charge is positive charge, as we call it, because it's structured backwards. He says that this is documented and published in the open literature, though no one really knows what to make of it. There are footnotes which point to the work being referenced, though I have never pursued it or looked at anything.
