is a treasure to be cherished*; just had another example of that.
Speaking to a guy who's an engineer who brought up post-tensioned concrete construction, and since I'd heard of it but knew nothing I asked for details. It seems that using that method isn't actually taught in school("There are EXPERTS who will do that", etc.).
One of the first jobs at the company he worked for, guess what the project he was assigned to used?
About oh-dark-thirty he and three other guys were sitting in the office trying to figure out how to make the specs they'd been given work, and it wasn't working no matter how they tweaked it, and they were accelerating down the ramp to screaming when one of the owners walked in("Just dropped by on my way home", which was BS because home was in the other direction from the airport), stopped in the door and asked what were they doing there?
"Trying to make 'X' work."
Heavy sigh. Slow shake of head. "Guys, it's not that difficult." Took a legal pad and, in half-an-hour on ONE SHEET, gave a college-level class on post-tension concrete construction that had all of them saying "Well, shit, it's not hard NOW."
He'd saved that sheet. And had, a couple of months before we met, used it to clear up the same mysteries for a new engineer with the company working under him(apparently it's STILL not taught).
That owner had been a professor of engineering; and I'll bet the students who came in after he left never knew what they missed. And probably never had someone who could do what he did.
*The followon is 'and bad teachers need to be thrown the hell out before they do more damage than they already have.' Which really pisses off the 'All teachers are wonderful!' idiots.
