Your not paying attention. FEMA and NIST, not just me, claim that “severe high temperatures” were involved in the eutectic reactions (the evaporation of steel samples) at the WTC 1, 2 and 7.
I see. Could you provide the source for the statements to which you are referring? I would like to check that when FEMA and NIST refer to “severe high temperatures” they are using the term in the same sense you are. However, given that you seem to mean “temperatures in excess of 1,500°C” – i.e. the approximate melting point of steel – I suspect not.
the question of the “severe high temperatures” was raised in the Open Civil Engineering Journal. so what are you taking about? The evidence is already there – what is lacking is a descent explanation!!!
This is another weirdly premised argument.
- The Open Civil Engineering Journal raised the question of P.
- Therefore P.
Listen i called the wtc fire a “building fire” because that is what it was; and because it was a building fire i also “consider” it to be a building fire.
The period in which the building stood burning was indeed a building fire. The point I am making, however, is that the period immediately following the collapses – the debris pile fire – was not.
I was not adducing a banality as you put it, i was stating a fact.
False dichotomy: Banality and fact are scarcely mutually exclusive characteristics. This very sentence circularly serves as conclusive evidence of the same.
I also stated other facts such as it being the longest ever structural fire in history, the first ever eutectic reacton observed in a building fire...
Petitio principii: The question of whether or not the reactions took place during the building fires – as opposed to during the debris pile fires, etc. – is precisely the point at issue.
...[the] New York Times described [it] as the “greatest mystery” of the investigation.
This is peripherally interesting, but not relevant.
[P]erhaps you can explain how a slow burning, low temperature, oxygen starved, water saturated smoldering fire of concrete, dust and office material can burn for several months and reach temperatures exceeding 1500c? heres another first; the first ever smoldering fire exhibiting all the above conditions to have ever reached temepratures above 1500c!
The eutectic reactions did not require such temperatures.
i dont give a bleep about the sandwich analogy
Argumentum ad tantrum: The question of whether or not a given argument appeals to your personal whims is, of course, of unlimited interest to all. When it comes to the events at the World Trade Center, however, it is sadly irrelevant.
Whats the fun in that? Playing safe is boring. Why dont you stick your neck out and make a claim?
Rationalism and extreme sports are worlds apart.
Because eutectic reactions have never been observed before in a building fire is intended to raise ones suspicions.
Petitio principii: The question of whether or not the reactions took place during the building fires – as opposed to within the debris pile fires, etc. – is precisely the point at issue.
Besides if your claiming that eutectic reactions were more likely to have occured under the debris pile because of “unusual conditions”...
I am not.
...i would kindly remind you that three steel framed skyscrapers totally collapsing on the same day from fire is perhaps even more “unusual”.
The above is a characteristically weird argument:
- Conditions within the debris pile were relatively unusual.
- But then so were collapses [and the factors which led to them].
- Therefore, the eutectic reactions took place while the buildings stood.
So what we have is the first ever eutectic reactions in a building fire...
Petitio principii: The question of whether or not the reactions took place during the building fires – as opposed to within the debris pile fires, etc. – is precisely the point at issue.
...[the] first ever collapse of a skyscraper from fire...
The above is similarly weird:
- This is the first time that these kinds of buildings have (1) either suffered high-speed impacts from commercial airliners or severe debris damage from a collapsing skyscraper and (2) undergone subsequent massive fires.
- Therefore, the eutectic reactions took place while the buildings stood.
But i was merely establishing the fact that those who investigated the incident did not rule out the possibility of eutectic reactions happening during the collapse. This is a reason that supports the claim that eutectic reactions occured during collapse. I am sure you can appreciate that.
I cannot.
Argumentum ad ignorantiam: The mere fact that a theory has not been proven false does not provide us with any reason to think it true.
Incidentally, until now I had been under the impression you were claiming the reactions took place while the buildings stood. However, going by the above (and some of your subsequent points) it seems you’re espousing a “during the physical collapse itself” theory. Strictly speaking, the reactions could have taken place during any number of the following rough and somewhat arbitrary periods:
- During the building fires: Between the time the aircraft (or debris) stuck the building, igniting the fire and moment just prior to the initiation of collapse.
- During the physical collapse itself: The relatively brief period between the initiation of collapse and the moment the roof of the building approximately reached the ground.
- During the debris pile fires: The period of a number of weeks that the debris burned underground.
Molybdenum has an extremely high melting point. Now speheres of that were discovered in the dust samples not the debris pile which suggests that they were formed during the collapse. If so, then the molybdenum spheres are exidence of extreme temperatures.
You seem to be relying on a very strange principle: “Dust samples taken from the site can only contain particles which formed specifically during – not before and not after – the building collapses.” Said principle, however, is straightforwardly false.
This by no means is a petitio principii and if dr greening and chainsaw concur that these spheres cannot be made below 1500c then its pretty much case closed, in my opinion, that temperatures for eutectic reactions existed during the collapse.
I wasn’t all that clear, admittedly, and so I’ll clarify: “This is something of a petitio principii. Whether or not the observation of the spheres serves as evidence of extreme temperatures [within the building fires, during the collapses or within the debris pile] is a crux point at issue.”
I agree. So i shall qualify my statement to something more affirmative i.e. the molten metal spewing from 82nd floor of south tower was in fact molten iron and that is evidence of a eutectic reaction occuring prior to collapse.
You seem to have replaced your lone conditional premise with bare assertion. This much is less weird, but equally unsound.
