I get a kick out of Mr. K's special treatments on history + effects on science in general. Hilarious 5 minute theses [plural according to google], and funnier yet to imagine him going back in those era presenting pro and con arguments. They wouldn't stand a chance, lol, against his reports on the result of their folly.
Not to linger afterward, want him definitely returned.
But he could stop off for a king-ship, know he'd enjoy that.
