No. Melting is endotherm, isn't it?
No, it requires an external source of energy, so exo- is correct.

I'm just wondering whether that particular element can be improved.
The techniques were developed over quite a period of time, and I'm personally not aware of any way to increase raw data accuracy. It's well sub-pixel already, and the limitation is the quality of the original recordings imo.
Aiii. I hope I've shown that even the poly(10) end result exhibits the same general profile as the far superior S-G acceleration derivation.The "particular element" I meant was precisely the smoothing. As I said in my initial post, it was really the Poly(10) that struck me.
All good.I had seen the Savitsky-Golay results before, but did not understand what I was seeing. Now I'm catching up.![]()
I've performed numerous tests, one of which may be of interest...I think I'd be interested in seeing some sensitivity analysis based on a single set of readings, but comparing profiles for various points somewhat serves a similar purpose.
You're welcome.Thanks for the very interesting work.
Pity their trace data results were so shoddy really. The havok caused by their published words was really unneccesary, and could have been avoided if they had applied a little more time/effort/focus. Poor. It's not rocket science.I read NIST, and there is no need for the data to be smoothed etc. It can be done like NIST did it.
My bad, that's what I meant. I reposted it in a hurry after my browser crashed when I had it written properly and got the term reversed the second time around. Sorry.No. Melting is endotherm, isn't it?
Actually Oystein was right. As a rule-of-thumb, EXothermicWP means the heat EXits as it is produced; ENdothermicWP means the heat ENters because it is absorbed.No, it requires an external source of energy, so exo- is correct.
I have to agree on the highlighted bit, but not on the corrective action. It was a really unnecessary study, with some hallmarks of being made in a hurry (as in, "let's put something together quickly to address this" without really caring about the quality of the final result), and what for? Just as a reply to purely accessory criticism. The influence on their conclusions? Zero. The focus of the report is, as it should be, on the initiation mechanism.Pity their trace data results were so shoddy really.

NIST have demonstrated a repeated and profound lack of effort/understanding/observation on many points.The focus of the report is, as it should be, on the initiation mechanism.

Specifically, without the nonsense of havoc and shoddy, how does your work change the NIST study?Pity their trace data results were so shoddy really.

My trace data for WTC7 is certainly of much higher fidelity and quality than that produced by the others you mention. Rightly or wrongly, none of those others spent about 18 months spare-spare time developing the methods and procedures required to generate such high quality raw data.
Here...

The red line (LHS axis) shows displacement (ft)
The black line (RHS axis) shows acceleration (ft/s^2)
If you want to call the period between 13s and 14.5s "about freefall", then fine, "about" 75ft "about" freefall.
At freefall ? Nope.
There's a couple of very boring and lengthy thread which discuss the process by which the data was extracted from video, along with direct critique of both the NIST and Chandler datasets. Have a peek.
Here is the NIST acceleration curve (in green)...

Where is there ANY time AT freefall ?
The red line spans 2.25s, btw.
Anyway, suggest you locate the appropriate threads for critique of the data. It is good data, and should be useful to all "sides".
People really need to have more faith in their own instincts and ability. In my opinion it is a major problem with society today. Every one looking for someone else to help, someone else with answer. So we have people turning to "experts" when their own natural instinct tells them something was very wrong with events of that day. We have people now turning to the government for protection willing to forgo some freedoms, become more of a police state. Which is exactly what the people who pulled of 9/11 wanted to have happen, and a main reason why it was done.
I agree with LSSBB. I don't think you can use common sense to understand something as massive as the first collapses of major skyscrapers in history. You really do need the science and expertise, not just gut instinct, to understand what happened.How do your natural instincts explain no explosions when you see it collapse? How many skyscrapers collapsing due to fire have your natural instincts seen for comparison?
What if your "Natural Instincts" are wrong? Or do you have some superpower all us mere mortals do not possess?
the reality is there really is no need to do measurements at all. All one had to do is watch the video a WTC7 to know it was a CD.
Does your rectal thermometer go up to 2000oC?Your quick google search fails. The response given to the question you linked is based on the peak burning temperature of Butane.
Butane also has an ignition temperature of 482-538 °C. Therefore, a bic lighter is somewhere between 482°C and 1970°C. Based on the tiny amount being burned, I would speculate nearer the lower figures, but hey, maybe tomorrow I'll go buy one and see.

C7 said:Conjecture
You shifted from melt to burn. You can't even keep your argument straight.cjnewson88 said:Conjecture that at 430C the red layer burns and the Gray layer doesn't?
Your video and images would say otherwise..
C7 said:That's Mark Basile's video and he says the gray layer did not ignite.
"But the gray layer basically seems to be largely iron, although there's some other stuff that's integrated into it too, it seems to have a fairly high carbon and oxygen content as well. But it doesn't ignite, it's just the red layer that ignites." http://911blogger.com/news/2009-08-2...s-911-wtc-dust
No, the gray layer is largely iron and iron melts at 1500oC. You will say anything no matter how blatantly absurd. We're done.Ok, so I am right, and my comment was not conjecture.
They all have WTC 7 falling at greater that g for a full second. That is not possible. In other words, this is junk science from an anonymous blowhard. Publish that crap in a peer reviewed journal before claiming to debunk NIST and Chandler.
It would take an external force pushing down to achieve greater than g for over a second. The interior columns falling at FFA cannot make the exterior columns fall at greater than FFA for more than an instant. NIST and a physics teacher with two masters degrees agree that WTC 7 fell at FFA for 2.25 seconds. FEMR's graphs are junk science.How is it not possible for something to head toward the center of the earth with an acceleration greater than g? Add gravity plus other forces and there it is.

They don't discuss the aluminum oxide as far as I can see. So what? That does not mean there wasn't any. They did say this: "Other iron-rich spheres were found in the post-DSC residue which contained iron along with aluminum and oxygen (see Discussion section)".It should be fairly easy for you to point out where Harrit e.al. describe white smoke, alumina, or analysis results of the DSC residue containing aluminium oxide.
It's the average. My use of the word "suddenly" was incorrect. The reaction took place between 370oC and 470oCThey actually ignited (started to exhibit exotherm reactions) much earlier than 430°C, but were heated to 700°C. There really is nothing special about this number of 430°C wrt to the producing of spheres.
C7 said:and produced iron-rich spheres with the same signature as the iron-rich spheres in the WTC dust.
Please, we are talking about the red/gray chips, not building materials.Very roughly, yes. It's apparently what happens when building materials, some organic, some inorganic, burn.
You are the one making that claim, you prove that it can happen. Don't ask me to prove a negative.Let's see you prove that they can't be pulled faster than g with a free body diagram.
How many times do I have to repeat this? I believe NIST when what they say can be verified by photos or in this case, by an independent researcher.And no, you can't keep hiding behind NIST whenever you feel like it and accusing them of fraud when you don't.
Who are you to say that? NIST was forced to change their story because it is easily recognizable that Mr. Chandler was right. Only the pseudo-scientists here say they are both wrong.And your other so called expert is wrong.
We agree (?) that Judy Woods DEW theory is baseless conjecture and doesn't fit the observed destruction.Judy Woods has a doctorate, are her theories right?
The gray layer is under the residue of the red layer so we can't see it in the photos. How could the gray [mostly iron and oxygen] side melt at 370oC to 470oC if not in a thermitic reaction?Harrit e.al., page 19:
So the red layer burned, the gray layer didn't, as per Harrit e.al. Agreed?
So where is the gray layer then? Do you see in Fig 20 how there is a lot of red layer left, but strangely any gray substance is now drawn to spherical shapes? Where did the gray layer go, and where did the gray spheres come from?
In Harrit's and your theory, the red, "nano-sized" iron oxide (particle size ~100-200 nm, just like ordinary red pigment) of the red layer was reduced to elemental iron, so anything that was red before should now be gone. That elemental iron allegedly formed spheres, aluminium oxide was created from elemental Al in the red layer, and the gray layer did not react.
