Science doesn't lie...
I am willing to bet that height he can't figure out is above sea level plus the height of the building
4 minute mark. free fall only gets slowed after the 3 second mark.
in his world this is evidence of foul play. to me is signifies when it got to the undamaged floors. the collapse starts with those above and it isn't until those levels get past the point of initial collapse that they slow down. perfectly reasonable.
5 minute mark. it was probably averaged. funny he doesn't go into what their result is actually saying. he even hints that he is "aimed" at a different result. so no wonder its different. and he says they started their clock early but offers no proof for it.
6 minute mark. the formula he is going on about is precisely what he says it isn't showing. AVERAGE.
7. he gets pissy that NIST wrote a report going to the idiots in Congress used simplified math? I saw some notes, those probably lead to the "real math". and its elementary before you start breaking something down you at least read and understand what its saying.
the expert is a high school teacher yet passes himself off as a professional? and the TRUTHERS use him as their expert? I would never expect him to understand these things.
8. he even says free fall shouldn't be in the conversation (WTF DO YOU KEEP BRINGING IT UP IF YOUR VIDEOS AND I HAVE BEEN SAYING ITS A POINTLESS TERM)
8.5 I already explained, if the point of failure is below there is nothing for the upper levels to crush/displace until they get to that point.
9. this is where his non-professional opinion matters none at all. I will say it again WE DESIGN THEM TO FAIL A CERTAIN WAY. BECAUSE IT MAKES EVERYTHING EASIER AND WE KNOW WHERE/HOW THE FAILURE WILL BE. IT SAVES LIVES. our code commentary even includes examples of why their requirements are such.
where is the sign of demolition? No flash, no bang, no dust coming up?
If I presented this in college I would have failed the assignment and something as sloppy as this at work I could be fired for incompetence. why you are sure to ask? for all the reasons listed above.
