I have already shown that I can admit I am wrong.
Let's take Cole's experiment out of the equation, just for a minute.
Is Richard Feynman wrong? Is his statement that is the title of this thread wrong?
I said you had fixed some of your errors. You acknowledged some of them, too. That was good. But what I was talking about is your impenetrable self-assurance in extending your "basic knowledge" - which you had said was completely correct
before you finally fixed errors in said knowledge - to the complex problems of building failure. You've made no progress there. You
can't, because you validate Cole because he agrees with your understanding which validates your understanding because it agrees with Cole. I explained this earlier.
That leaves you in the position of rejecting anyone who disagrees with Cole (and you) about WTC collapses if -
(1) He is an expert
(2) He is not an expert
You do this with the same vehemence as you defended the basic physics errors we finally talked you past. That should really set of the warning buzzer in your head.
Let's not leave out Cole, because your absolute conviction that you are applying your "basic knowledge"
appropriately and correctly to his model, or anything that anyone else says about it, is the essence of what I'm talking about. I haven't said whether you're right or wrong about it; I'm saying you can't
evaluate whether you are or not, because you're sure you're right, and you've set yourself up to be unable to conclude otherwise no matter what you are told.
As for the quotation, an experiment has to be able to model the real-world behavior accurately, within known limits and minding appropriate caveats, to be of any use. People are telling you Cole's experiment does not; but again, the problem I'm pointing out to you is that you're unable to do anything other than reject them, whether or not they are right.
