If it doesn't agree with experiment, it's wrong. Part II

Is it too late for you to ask for a refund?

Yes, as a matter of fact, it is.

When I went to work for him, I was about 25 years old, and still wet behind the ears. Don was about 65, a distinguished, elderly, engineering hard-ass, who had cut his teeth as.a project manager (not an engineer, but a very practical, smart person) & then VP at Convair, in San Diego. A giant, successful aerospace company. An engineer's company.

He was an old school Republican, and I was a wild haired liberal from Boston, who had moved to San Diego right out of college.

I figured I was going to change his political / philosophical opinions about the world. One of us changed. It wasn't the one I had anticipated.

Don passed away about 15 years ago. Fortunately, I got several opportunities to drop back in & see him after I'd left the company. To thank him for being as demanding of me as he had been, and for being a great boss.

He was proud of my successes.
I was honored to know a fine, exceptionally competent, mentor.

Subsequently, I was the mentor for about 25 baby engineers, over 3 generations. That's the way it works in this profession. Some of my "kids" went on to do spectacular things. One was one of the finest, most successful engineers that Hewlett Packard had.

What on earth is your idiotic "ask for a refund" comment about?

And? (assuming it's concrete and not smoke).

I am sorry that he is no longer with us. I do mean that.

Now, on a separate note, if you took the politics out of the equation, and just showed him the collapses, he would laugh at you for saying the things you do. He would wonder where he went wrong.

He would probably drop a bowling ball on your head to remind you of what freefall is.

Actually, he would just probably make you take a middle-school level physics class to remind you of the basics.

In middle school science they taught us about Terminal Velocity, which is the fastest speed a falling object can achieve based on the resistance of whatever it's falling through. Truthers, because they're morons, invented something called "Free Fall Speed", an unscientific term that has no real-world meaning nor function in physics nor science.

Your bowling ball would fall freely to the ground, but would not achieve Terminal Velocity if it was just dropped from the height of an average man. There is a formula to calculate how high you would have to drop the bowling ball to achieve that speed.

You can see the factors you need to know to make the calculations here:

http://www.calctool.org/CALC/eng/aerospace/terminal

The problem is that Troofers have confused Terminal Velocity with their silly free fall speed. The problem is that Terminal Velocity is a quantifiable, provable, reliable factor whereas free fall speed is whatever some moron wants it to be.

For example WTC never collapsed at it's potential Terminal Velocity.
 
Just a quick note. The Lurkers are not impressed with whatever you would call FF's ramblings. As it was ever thus.

The floors? Concrete.

Stop showing verinage. Concrete is not steel.

So? That's a really poor evasion. You are alleging that the concrete in the towers pulverized, and I'm showing you an example of how concrete is expected to be pulverized and what effect is expected to be seen on impact of concrete surfaces. The amount of dust is expectably high even from a small quantity of pulverizing concrete.

So, back to my original question:

The arbitrary time that NIST used is 5.3 seconds long. Please show me where NIST uses a collapse time of 18 seconds.

Redwood said:
It's all in NCSTAR 1-9, FF! Table 5-3. It actually adds to 16.5 seconds.

YOU HAVEN'T READ THE REPORTS, HAVE YOU, FF? How do expect to hope to refute NIST with anyone from Pete and Patty in Peoria, to the world's scientists and engineers, when you haven't even read the reports you're trying to refute? :rolleyes:

No idea where you pull that number out of (ok, I do have an idea), but this is what NIST say:

Beginning at roughly 6.9 s the brightness increases irreversibly to a value of 100 percent at which time the pixel under study represents the sky. Thus, the relative time at which the roofline began to move was estimated as 6.9 s. The time when the roofline dropped from view behind the buildings in the foreground was 12.3 s. Thus, the time the roofline took to fall 18 stories was approximately 5.4 s.​
NCSTAR 1-9 vol 2 p.601

So the question is, when will you admit that you're wrong?
 
A fair amount of material expelled laterally as the twins collapsed was the easily pulverized clg tiles and gypsum wall board... the concrete was, to use the truth term... dustified as the collapsed progressed... much the way stone and concrete is dustified in industrial tumblers...collisions make dust. More collisions make more dust. Fine dust can be carried in the wind... even sand... and that's what happened to the friable material in all 3 bldgs... carried aloft and deposit down wind.

I was bored and I watched parts of the video. I guess you think concrete pulverizes itself in midair. It can't, but I know I'm not going to change your mind.

It's also interesting to see the explosion about two floors below the fire line in WTC7 a few minutes before it collapses. I guess you don't see that.

I guess you also don't see the numerous smoking projectiles that come out of both towers at an almost regular basis. Every single one of them spins and leaves a curly smoke trail as it falls. I guess you have an explanation for those things, or you just ignore them.

You see what you want to. I get that.

What do you think caused this to happen?

I have my :popcorn1 ready or is this where you trot out the cowardly "I'm not an a expert, I'm a clueless dolt" and dodge yet another question?
 
tfk said:
Now that I've answered your question, are you going to answer my question & show us exactly where the explosions happened in WTC7 that you claimed??

Or are you going to run away from your own assertion??

That's all Junior here is capable of. Remember him bailing from the conversation after it was proven NIST's collapse time was much more than the ~6 seconds Junior says it was?

Now that schooling is on some page in some thread somewhere, and it's safe for him to slink back in here and spew more bile.
 
The last video he posted undermined every argument he's made since he's been here.

  • No explosions
  • concrete chunks flying
  • Not reaching terminal velocity (free fall speed if you're a dpistick)
  • WTC7 receiving serious damage from WTC1

It's like he secretly wants us to believe that Al Qaeda hijacked a bunch of commercial jetliners and flew them into the WTC.:jaw-dropp

Typical truther methodology.

If at all possible, present your evidence in such a way that it completely refutes whatever point you just failed to make.

You show smoke and lie. Like no plane liars, but you lie about concrete which can't be crushed instantly but after time. Thus you are a liar base on your fantasy version of 9/11 which never existed. Better luck with the planes, where were all proved with Radar Data.

Why lie about smoke being crushed concrete? Wallboard crushes easy, as does the under-floor insulation. You are missing reality, and playing the BS card.

What is your point? there are no explosives, adn thermite does not pulverize concrete; , no explosions are seen.

https://pubs.usgs.gov/fs/fs-0050-02/fs-050-02_508.pdf

You lie about 9/11, and you have no clue what the dust was made up of, and ignore the smoke. Why do you lie like no planers lie?

He's just trolling now. Don't feed the trolls. But maybe, just maybe, we can encourage him to post the Cindy Weil video to Truther sites and proclaim how it shows demolition charges going off!
