Nice photos, Turbo. Where did you get them?
I choose not to post personal information but you should know that I have run DSC's and TGA's for many years. You have still failed to interpret Jones' DSC trace of the red paint. Do not feel bad, Jones misunderstands it also.

Those are photos of my lab pt. Not bad for a HS drop out huh?
If you thnk I'm going to believe you (whom wont disclose his credit)
over nine Ph.D.'s you're nuts. Your assessment of the DSC trace implies
that LDRD has no idea what they're doing either.
Just remember, LDRD is a government lab that tested a known nano
thermite. I guess there's burned longer with less energy and therefore
they were mistaken too?
ldrd.llnl.gov...
Thanks, but no thanks pt. It's clear your assessment is incorrect...
Originally posted by pteridine If you claim to be an engineer or computer scientist, I will go with that for now.
What government lab is LDRD?
but the researchers are contractors and not Federal employees.
Doesn't this seem a bit long for an explosive, highly energetic nanothermite?
Given this, now what do you think is happening in the DSC trace?
You may either appeal to authority and blindly support Jones or ...

Originally posted by exponentAgree, kinda. It's not energy generated by momentum as much as energy stored in the angular momentum. Other than that semantic argument, yes at some point the block has essentially no angular momentum.
The tilting block both had stored and kinetic energy; as in all of the
stored energy was not used instantly.
We agree that at the point the tilting stopped, the kinetic forces/energy/whateveryouwannacallit no longer acted.
We can estimate that the load was distributed amongst the many perimeter
and core columns at the point rotation ceased.
Agree, or disagree?
We can't really say for sure, once the block has rotated even a few degrees, many of the perimeter columns are disconnected and the global collapse has begun. At the point which rotation appeared to cease, the block was tilted by a significant proportion, and no column impacts would be axial.
What columns do you suggest played a role in securing the upper block
from rotating further and/or falling off? Would you agree there would
be two points of interest as a tilting object needs a fulcrum, and a vector
force to rotate? In this case we need a fulcrum and an arresting
(opposite) force to stop rotation.
We also know that all core columns were not cut, and approximately 4/5
were still intact when the floors stopped rotating.
Agree, or disagree?
We don't know this for sure, bending of the core columns would undoubtedly sever them at some point, they were very much not designed to take this sort of load. You'd have to go into a bit more detail before I can agree or disagree.
I don't agree that the ~32 core columns and ~200 perimeter columns
could not support the upper block after impact. There are a studies from
architects and examples of FEA that show the upper block should not have
even moved!
Also from video/photo evidence it is clear (to me, and others) that the
positioning, and destruction of the upper block is not from gravity alone.
Please refer to an angle between the top and bottom sections that would
indicate in your mind that core columns broke "post aircraft impact".
Select a time in a video, or angle in a photo at which time you feel any of
the arresting columns broke. Study them well, and study several different
angles of the South tower as your "point it time" must show the tension
side of the building (West wall) at full length.

This is basically what has Judy Wood so bugged. It's looking more now like she is off the track with her theory of some kind of beam weapon being used in the attack and that the Stephen Jones camp may be correct with the nano-thermate evidence, but the fact is that a lot of the tower seems to have gone up in smoke, never even hitting the ground.
It is also looking likely that the large numbers of incinerated vehicles near the towers were incinerated by active dust emanating from the towers. I can't think of any other hypothesis to explain that phenomenon.
It's a strange convoluted story, 9/11. Only in Amerika.

How about the video link of the close up flashes happening in the towers?
Did anyone give those a look? Are you convinced yet?
