Trust me, its him.
If it is, he has the beginnings of senile dementia...why did he call me out in his "list" considering i have not even mentioned the NIST in this thread and in no case am I one of the heavy posters of science in this forum. Sorry but this is 28th Kingdom or at worst it is another pdoh sock. Wasn't there a thread here recently mentioning the troubles Greening was having registering here? We all question lots of things but when someone comes here and claims to be Dr. Greening although they are slinging theories opposite to what he is know to have said, we believe his story? Sorry but I am not going for this circular CT rideTrust me, its him.
Since I don't want to sit through a 60 minute video, is it the one that shows a claw picking up a chunk of red-hot (not molen) metal?Boloboffin..Yes there was molten metal for sure. You can see it on a 60 minutes video that used to be linked at http://terrorize.dk/911/.
Hubcaps are not made from steel, usually aluminum which melts at far lower temps. And I've seen plenty of car fires, nothing more than the materials in the car and the supply of gasoline is needed to make quite an impressive fire.The fires in the basement melted the hubcaps off of the cars.
Chainsaw PM'd the correct answer to me, and it is the correct answer.Didn't see that. Yes it is up to Chainsaw the crazy man to confirm it and I can tell you that I still have my doubts.
Hit a chunk of concrete with a hammer and sparks fly. A spark is a tiny bit of molten iron, correct? I'd imagine there was quite a considerable amount of sparks generated through friction from the collapse of the towers, but I'm no scientist.Apollo:
Spherical Iron particles = possible Molten iron...ok, I can buy it, others with physical science background here seem to agree. Many things can cause "molten Iron".
As well as he did me and it is 2/3rds of the correct answer. Anyway, what happened to the recent troubles Dr. Greening was having when he tried to register before? Does MikeW have the email from his website and is Apollo's the same? Did he register as Frank Greening as per policy? I also would like him to explain why he used my name in his "hit" list and why it is extremely similar to pdoh's list. I still believe he is 28th kingdom but I would really like to hear him say condoneChainsaw PM'd the correct answer to me, and it is the correct answer.

Does it require a Physicist to debunk the concept of controlled demolition?
Really?
Does it take an engineer?
The sheer impossibility of such an operation, and the absurd impracticality of such a plan, and the further impossibility of covering it up don't require pages of complex equations. It only takes a basic knowledge of the evidence.
Finally, I have to remark that the level of discourse in this thread is highly disappointing. There is a perfectly reasonable scientific discussion hidden here, but the signal-to-noise is pretty low. And some of that is JREF regulars. I ask you all to lower the level of antagonism here, or find another thread if you cannot.
TAM: Spherical iron is my main evidence for molten iron
KENT1: Plastics burning is a very important factor
Chainsaw: About the zinc - yes indeed!

Not a whit. Thanks for your reply about the iron particles. Your explanation of why the sampled particles are less likely to have been the result of cutting activities seems reasonable.But I was assuming you had some technical training and/or experience…...
Spherical iron particles are direct physical evidence that the iron within the particle was molten at the time the particle formed.
Each of the references below specifically mention the detection of iron spherules in WTC dust samples (and in most cases also provide electron micrographs of the particles in question). Reference 1 includes two such micrographs labeled IRON-03-IMAGE and IRON-04-IMAGE. Reference 2 discusses which WTC particles could best be used as signatures of WTC dust; iron spheres were considered and rejected only because they were not found in ALL indoor dust samples. In reference 3 we read on page 17: “Various metals (most notably iron and lead) were melted during the WTC event, producing spherical metallic particles.” And finally in reference 4 we find a micrograph of a spherical iron particle and the comment that WTC dust contains evidence for “heat effected particles, including spherical particles.”

2.3.5 Heat affected particulate and combustion products
Particles that either were formed as a consequence of high temperature or were modified by exposure to high temperature are important WTC Dust Markers for WTC Dust. Fires that were a part of the WTC Event produced combustion-modified products that traveled with other components of WTC Dust. Considering the high temperatures reached during the destruction of the WTC, the following three types of combustion products would be expected to be present in WTC Dust. These products are:
• Vesicular carbonaceous particles primarily from plastics
• Iron-rich spheres from iron-bearing building components or contents
• High temperature aluminosilicate from building materials
There were considerable amounts of plastics in the WTC buildings, that upon heating and liberation of volatiles produced spherical (or nearly so) carbon-rich particles with vesicles related to emission of volatiles. Figure 18 shows typical carbonaceous materials from a Background Building and Figure 19 shows porous heat affected particulate in the WTC Dust. Figure 20 shows a PLM image of porous heat affected particulate in the WTC Dust.
Various metals (most notably iron and lead) were melted during the WTC Event, producing spherical metallic particles. Exposure of phases to high heat results in the formation of spherical particles due to surface tension.
...In addition to the spherical iron and aluminosilicate particles, a variety of heavy metal particles including lead, cadmium, vanadium, yttrium, arsenic, bismuth, and barium particles were produced by the pulverizing, melting and/or combustion of the host materials such as solder, computer screens, and paint during the WTC Event.
Combustion-related products are significant WTC Dust Markers, particularly if seen in combination. However, it is worth noting that fly ash and partially combusted products can occur in trace concentrations in ordinary building dusts, but not in the concentrations observed in WTC Dust.

"In addition, elements such as aluminum, iron and in some cases zinc, vaporized during the conflagration and condensed on the chrysotile surface, an effect only observed in fire damaged circumstances."

It would be interesting to know why such particles would be expected to form and be released in such a fire, and what building components they are most likely to come from.P. 39
The catastrophic structural collapse of the WTC Towers produced fine particulate matter including fine dusts and short fractured mineral wool fibers. The U.S. EPA reported (U.S. EPA, 2002) that the WTC Dust displays calcium sulfate (gypsum) and calcium carbonate (calcite) as major components of the fine dust fraction, indicating that very finely crushed building materials are significant components of WTC Dust. The conflagration reduced existing materials into spherical metal particles, spherical and vesicular silicates, and vesicular carbonaceous particles. These dust and heat-processed constituents are rarely, if ever, found together in “typical” indoor dusts. While gypsum is commonly part of drywall and plaster, it has a dramatically different shape and size than the gypsum common to the WTC Dust.
P. 40
In the WTC Event, the intense heat and subsequent burning of debris resulted in the emission of particles whose morphology (characteristic shape) was influenced by the heat – spherical or vesicular. Figure 4-4 shows a spherical iron particle resulting from the melting and/or vaporization of iron building or content components. Figure 4-5 shows a vesicular carbon particle resulting from the heating of plastic. Figure 4-6 shows a lead particle.

I had read these papers in the past, and seeing your links made me wonder why I had missed the mention of the iron anomaly. On re-reading them the reason is clear: because it isn't an anomaly. The release of spherical iron particles is apparently an expected result of this kind of fire, which is why the researchers were hoping to use those particles as a marker to differentiate WTC dust from background dust. The researchers didn't just happen upon those particles: they looked for them because they expected them to be present.
It would be interesting to know why such particles would be expected to form and be released in such a fire, and what building components they are most likely to come from.
If it's Greening, then he should be ashamed of the way he's behaved here.
