10:13:01 From Barry Kort to Everyone:
	Non-Markovian Do-Over ~ The State of Knowledge increases with each iteration.	
10:38:20 From Barry Kort to Everyone:
	The fact that that time ticks at different rates, as a function of the strength of the local gravitational field also explains why Bell’s Inequality does not hold in our cosmos.  Bell tacitly adopted Newton’s simplifying assumption that time ticks at the same rate everywhere and everyone.  Dispense with that unrealistic simplifying assumption, and the mathematics of deriving Bell’s Inequality gets thrown into a cocked hat.

	E.O.Wilson was a Lexingtonian

11:27:59 From Barry Kort to Everyone:
	Humans have uniquely adopted Crime and Punishment as a formal method and mechanism of socio-cultural regulation.  Mathematically speaking, that’s an infelicitous invention, as it promotes state-sponsored violence under the color of law, along with political drama, conflict, and systemic injustice.  Did EO Wilson ever opine on that?
