Invitation to Derek Johnson to discuss his ideas

...
At least the lurkers can see their manifold question ducking and incompetence with basic science.

You are here claimning to be able to read the minds of invisible and unknown people.

You have reached the realm of jammonius with this. That is, the probability that your delusions reflect a clinically significant mental disorder is significantly higher than 0.
 
The cool part; you don't need engineering skills to figure out Derek's claims of thermite and CD are moronic nonsense.

No kidding. I am not an engineer. I am a former military fire fighter, a retired mess sergeant, a construction and industrial laborer and a poet, and I can see hundreds of ways the Da Twoof is BS, especially as relates to molten steel and thermite.

Da Twoof is a symptom of a bizarre sort of mental myopia.

Yes, engineering school would be a waste of time to figure out Derek is pushing the same old debunked CD and thermite crap. I could have figured this one out when I was 11, after I blew up my back yard with sugar and KN03. And over in Saudi Arabia, having a 360kg blast blow out my office windows helps understand what you hear, AND FEEL, when explosives go off.

I watched his presentations, they take over an hour and he spews lies nonstop. I can't imagine why he pretends his engineering questions will help him back in his idiotic CD claims, and he is deep into thermite.

Derek has some other motive. Of the hundreds of engineers I went to school with and the hundreds of engineers and scientist at AFWAL I worked with, not one of them has signed up with the frauds at AE, Gage's personal money pit of travel and living expenses. It is not illegal to take money from the gullible. Is Derek ripping people off; if he is he must get a cut or a speakers fee.

He must be frustrated if he knows he is in a scam, so he is here trying to redeem his engineer skills. If he had something in engineering, he would publish it and earn praise and fame; but he has delusions of thermite. He can't publish, it would ruin him.

Hi lefty, I was trained and tasked with fire fighting in the Navy. I've also been in construction for a while...and I'd like to point out to you that beachnut leaves something out here:

If anyone were to answer the questions (yeah right) I laid in front of them in #1152, I'd present them with some nasty things that Da Twoof-crushers are terrified to confront...and won't confront. It's too bad for them that science is on my side. The WTC 7 collapse required energy. What I can prove is the stability. This is where #1152 leads. Avoid it like the plague JREFers, there is no light for you at the end of that alley.

But please consider a glaring contrast here:

1. Tom (Da Twoofie-Annihilator): "But the right answer is contained in the FEA analyses"

or

2. The NIST objections regarding the FEA analyses in posts #1400 & 1475.

???

Leftysergeant my friend, if there is error in the charges laid out in these two posts, please point them out to me.

If you or others here can’t find error in 1400 or 1475, then these charges are correct. If these charges are correct, then "Da Twoofie-Annihilators" at the JREF forum are supporting a heavily flawed report with an acute denial of this board's namesake’s philosophy. Let me be the first to suggest a name change: The Sometimes James Randi Education Forum...TSJREF.

Only one of the two below is correct, so which is it? Choose.

1. Tom (Da Twoofie-Annihilator): "But the right answer is contained in the FEA analyses"

or

2. The NIST objections regarding the FEA analyses in posts #1400 & 1475?

Thank you,
Derek
 
if he is he must get a cut or a speakers fee.

Nope, no speakers fee. I do this at no charge. Tell me beachnut, are you technically able to answer the questions in post #1152?

If so, what are your answers?

Also beachnut, did I get anything wrong in posts #1400 or #1475? If so, what? List them please. There are a lot of charges, if you are unable to find the error, the charges stand.

And you call "Da Twoofs" delusional?

Tell me Derek, in your training as a firefighter in the Navy, did they teach you how to identify molten metals by sight alone?

If not, than why do you expect the FDNY to be able to do so? Or really, anyone else for that matter, outside of a metallurgist.

Can you identify the materials that Oye posted a while back?

If you can't, just admit it. I know I can't, and I have close to 16 years of professional firefighting experience. It's not something that we as firefighters are taught. We have no need for that.

Did they also teach you about thermal expansion in the Navy? They should have.

So, what your saying is that, unless we answer a loaded question and become twoofers for a day, you won't provide us with the rest of your super-sekrit theory?

Sounds kinda lame...asking for an answer before we hear or see your end data. That's very bass-ackwards of you.

Leading us to the promised land, are you? But only if we show we're worthy by drinking the kool-aid before we get enlightened, right?

Stop trolling and spamming. Go find something better to do.

I was taught the subject you bring up in Nuke school, not much, but it got a more thorough look later at UTA. I absolutely agree upon the phenomena, but I (and many others) challenge NIST's woo claims in posts #1400 and 1475. Please read them and we'll further discuss thermal expansion vs. differential movement.

You're right triforcharity, I admit that I can NOT identify molten metal by photos alone. You got me, da twoofie is vanquished....or maybe not so much.

However, in person, as the firefighters were, there are other factors: smell is one, dross formation and appearance is another, the available fuel, availible oxygen, ambient conditions (light, wind, temperature), spatter, smoothness, flow rate, coalescence, radiance and so forth all factor in. The hard part for me to understand is the coalescence of the metals TFK-Tom landed on (lead, aluminum and tin). Not much mental strain is needed to rule out lead and tin, therefore the coalescence of molten aluminum is your best argument.

Did the firefighters really see "molten aluminum" as Tom suggests they might have? This is the only reasonable alternative theory from their repeated "molten steel" statement, and it is worthy of futher discussion.

You'd have to have a concentration of aluminum for this coalescence, not to mention just the right light and dross for this mistaken identification. The aluminum in buildings is pretty scattered and distributed in a manner that is not highly amenable to easy coalescence. You may be right, I admit that, but given the tiny fraction of aluminum of this structure (compared to steel), not to mention the unlikely coalescence, which renders this argument as one that is leaning more towards "da twoofs are nasty America-hating, Islamic extremist supporting, idiotic tinfoil hat morons" wishful thinking than simple reason. This is why I asked the question: please give me the metal fractions of WTC 7. This leads the twoofie-slayers down a very dark alley as well.

Those are my thoughts. A favor please, seek answers to the questions I raise in post #1152 and let's have a chat about those answers, ok?

Also please do me another favor, point out all the error in posts #1400 and 1475. What remains unchallenged will stand as correct, and should be brought to NIST for a correction.

Is that fair?

Thanks,
Derek

No, that would be Joshua.

I am leading you out of your delusional belief that NIST is telling you the truth. Please seek answers to #1152 and we'll see whether it is NIST or engineers like me (and thousands of others) are lying. We can't both be right, and I am not getting paid for this. NIST was well paid for their report (by taxpayers like you and me).

Someone is lying, and if you think it is me, I kindly point you to what I have laid in front of your feet in posts #1400 and #1475. Please spot the error therein and call me on it. Ok?

(massive wall of claims snipped)

The horizontal progression of failure was sensitive to the extent of the estimated initial structural damage in WTC 7 due to the collapse of WTC 1. NCSTAR 1-9, p. 612.

"The initial westward progression and the overall speed of the collapse was [sic] not sensitive to the extent of the estimated structural damage to WTC7 due to the debris from the collapse of WTC 1." NCSTAR 1-9, p. 625.

Which is it? What changed NIST's opinion of this "sensitivity" between NCSTAR 1-9, p. 612 and p. 625?

(remaining massive wall of claims snipped)

I'll have a go at this one. It looks to me like the difference is due to p. 625 being a summary. In detail the collapse was sensitive to the amount of damage, the failures are quite different in appearance when damage was included compared to when damage was not included.

The broad features, however, remain the same. Westward progression of the interior collapse and the basic speed of collapse were similar in both cases.

No.

You contend that 79 couldn't have buckled because of whatever.

Prove it.

Stop playing this lame ass mouse trap game and get on with your data.

I'm not playing any game. And you will see the column analysis that I presented in Atlanta twice last weekend in a few months. The analysis was checked by other structural engineers with considerable more experience than myself.

What I am offering TSJREF (The SOMETIMES James Randi Educational Forum) twoofie-debunkers is a challenge that I'm guessing they can't meet. I hope there is at least one person here that can get #1152 answered, I'm losing hope at a rapid rate that anyone here has the technical ability to answer these question unaided, but who knows?

You can scream prove it all you want. Or you can print these questions out and commence your own research with an open mind. My mind is still open. Others that frequent this board, not so much it appears.

Thanks,
Derek

You have a delusion thermite caused the WTC complex to fail. You are wrong, no amount of your idiotic engineering claims which have nothing to do with your failed CD claims will help your failure.

I posted two lies you make, out of many in your presentation; you failed to take the challenge and correct them, or discuss why you lie about 911. 9 years of failure and you fail to publish your engineering BS challenge, which is only a show so you can post this trash talk.

Just how many hours was your firefighting class? And how many others took the class? I think I can answer that; not long, and everyone else that was aboard the ship.
In the real world of firefighting, a firefighter will spend over a hundred hours in school just to meet the requirements to ride the engine.

"The steel was assumed in the FDS model to be thermally-thin, thus, no thermal conductivity was used." NCSTAR 1-5F, p 20

and

“Although the floor slab actually consisted of a metal deck topped with a concrete slab...the thermal properties of the entire floor slab were assumed to be that of concrete [1.0 W/m/K]." NCSTAR 1-5F, p 52

and loaded these values into their 16-story ANSYS model:

Item Actual Density lb/ft3 NIST woo Density lb/ft3

Steel 500 0.5
Concrete 150 0.15

Why did NIST assign densities of the beam and shell material 1/1000th that of generally accepted engineering values in the 16 story ANSYS model? Guesses?


And while I'm here. You seem to be confusing the fire modelling and the structural modelling. The beams are assumed to be thermally thin based on the results of the fire tests and the presence of the metal pans under the concrete floor doesn't affect their behavior due to fire.

The fire modelling is then applied to the ANSYS structural model.
 
This is exactly why the "buckling-expanding" beam initiated is easily debunked. You can't have this both ways. If the floor beams buckle due to any one of or combined effects of lateral restraint, increased axial loads etc., their ability to push for a "walk off" of the girder to column 79 (2 above, 2 below) 4 x 7/8" A490 bolt connection just does not exist. If so how? The intersecting girder wins if the beams buckle. Please explain in detail if you disagree.

You are assuming that the buckling of the beam relieves all the presure on the girder. Silly thing to assume, especially if there are still fires sending out random blasts of heat to change the temperature, thus the volumn of the steel it meets.

Of course the beams were not unrestrained, but by NIST's statements (and some help from computer model's 'relative displacement'), the beams both buckled and pushed the 79 to 44 girder. Which is it? And how can you have both? Either the beams buckle (figure 11-27, 11-35 and figure 8-27) or they expand to break the seated connection. Pick one, you can't have this both ways. If the beams are unrestrained at one end, how can they develop the compressive force necessary for buckling to occur?


One of Newton's laws about an equalk and opposite reaction.
If thermal expansion of the floor beams did not displace the exterior frame, then how would buckling of exterior columns occur?
They were holding up m,ore weight than they were supposed to hold. DUH! Some of them were broken when a bunch of steel stuff slammed into trhem, so they shared the load with other columns. That gets old after a while.

And the shear studs, by which NIST derives it's differential displacement woo. Different NIST reports say different things about shear studs on girders. If any steel was retained we might know this, but 100% of WTC 7 was China-recycled.

No, we do not know that. Document that crap. We have been over this same BS before here.

Finally, There was no steel debris examined, so how does NIST know there were no shear studs on the 13th-floor girder spanning between columns 44 and 79? Wouldn't the contract documents and structural plans settle this? FOIAs are pending.
Citation needed.

NIST states that ''even though steel and concrete have similar coefficients of thermal expansion, differential thermal expansion occurred between the steel floor beams and concrete slab when the composite floor was subjected to fire." (NCSTAR 1-9, p. 490.) This relative displacement occurred in the ANSYS model, and no physical testing was done to verify its magnitude in the steel-and-concrete structure.

And it is counter-intuitive to expect that materials with similar physical porperties will react in identical ways. Where's the beef?

Of course NIST didn't take steps to maximize the destructive effects of any relative displacement due to thermal movement. Who would ever even think to do such a thing?

Everything needed to maximize the results happened in the building anyway over a five-hour or so period.
 
...
You're right triforcharity, I admit that I can NOT identify molten metal by photos alone. You got me, da twoofie is vanquished....or maybe not so much.

That was easy, wasn't it? Why did it take your 4 months of evasion?


However, in person, as the firefighters were, there are other factors: smell is one, dross formation and appearance is another, the available fuel, availible oxygen, ambient conditions (light, wind, temperature), spatter, smoothness, flow rate, coalescence, radiance and so forth all factor in.

Tell us more of these factors. Is that something that firefighters or other responders are taught in their professions?
Are these methods reliable in the conditions of a huge, stinking, burning, fuming trashpile?
Can you show that any of your witnesses actually used any of the factors or methods you hint at?


The hard part for me to understand is the coalescence of the metals TFK-Tom landed on (lead, aluminum and tin). Not much mental strain is needed to rule out lead and tin, therefore the coalescence of molten aluminum is your best argument.

Did the firefighters really see "molten aluminum" as Tom suggests they might have?

Most of your witnesses have not seen anything molten at all. Most are second hand.
In some reports, it can even be doubted that whatever they saw was molten.

This is the only reasonable alternative theory from their repeated "molten steel" statement, and it is worthy of futher discussion.

You'd have to have a concentration of aluminum for this coalescence, not to mention just the right light and dross for this mistaken identification. The aluminum in buildings is pretty scattered and distributed in a manner that is not highly amenable to easy coalescence.

This is of course not true for the twin towers, whose entire facades were clad in aluminium, and who had received planes with tons of aluminium right in the core of the burning inferno.

You may be right, I admit that, but given the tiny fraction of aluminum of this structure (compared to steel), not to mention the unlikely coalescence, ... This is why I asked the question: please give me the metal fractions of WTC 7. This leads the twoofie-slayers down a very dark alley as well.

Uhm - do you have one (1) confirmed first-hand witness for molten metal in the WTC7 pile?


However, if we assume, for the sake of argument, that some reports of molten steel are true.
We then need to look at WHEN that molten steel was observed, and where. That would generally be at some time T after the collapses.

If T is > 2 hours, say, you'd have to explain how steel that melted during or before the collapse, and thus can be suspected of having been a contributing factor to the collapses, could have stayed molten for so long.
If T > 1 day or even 1 week, that problem becomes more and more problematic, obviously.


In other words: You guys need to spell out a theory that would both provide a scenario for intentional collapse, and explain the presence of STILL molten steel hours, days, weeks or even months after the collapses.

Without even a technically viable hypothesis here, there really is no point to even discuss this molten steel issue.



(Disclaimer: Do not construe the preceding paragraphs as admitting to a significant probability that molten steel was indeed found. I maintain that you have zero evidence for molten steel, as there is no hard evidence, and as you can't show that a valid method to identify steel was both available to and used by the few genuine witnesses who reported "molten steel" first hand. We know already that it can't be done by sight alone, as you finally admitted. The witnesses only said that they "saw" molten steel, not that they smelled it or assed dross formation. So for all we know, all witnesses employed an invalid method)

Is possible to get one or two names here? So we can check whether you are lying or not?

And the amazing Truth is that most of them admit that WTC7 looks like a controlled demolition. Then to follow that up they cannot answer those few simple questions that might help the OCT find some wriggle room.The poor OCT is out in the cold now and it's handmaidens are threadbare with the cupboard almost entirely bare.

All they can actually do is dissemble and mob you with dozens of denials hoping that the Readers, now and in the future will be swayed by the sheer volume og people opposing you. Straight from the propaganda manual.

But it's good times for us now and a few Truthers can run hordes of these guys ragged as you are doing here and others are doing elsewhere.
