gravity makes things go down.
what do you think made the WTC go down? magnetism?
radiation?
heat?

It sounds as though Tony is still counting the expected resistance twice: once to produce the sudden jolt he expects, and again to slow the acceleration to 0.7g. For discussion and a link to the relevant graph, seeIf you read the Missing Jolt paper you will see that the basis for saying there was no deceleration in the fall of WTC 1's upper section is that there was no measureable velocity loss during the time it would take the velocity to recover to what it was pre-impact, over a significant period where 4 data points were taken.
Tony's right about the second derivative being unnecessary here (albeit instructive), but his highlighted statement is completely false. Computing the first derivative by simple differencing definitely shows a velocity loss. That graph can be seen just a few posts above.The problem for your point is that it isn't necessary to take a second derivative and it is less precise than the first derivative, which shows very clearly that there was no velocity loss.
Tony has just confirmed the suspicion expressed by Dave Rogers:Any small error in the symmetric differentiation of the distance vs. time of those four data points in the velocity recovery period would not possibly allow one to say a velocity loss was being smoothed out.
Quite simply, his data analysis is appallingly bad. He seems to understand nothing about experimental errors or the effects of data smoothing; indeed, he seems unaware of whether he's smoothing his data at all!
From which a reasonable person would conclude that the collapse of the WTC towers was not a well-controlled Verinage demolition. Earlier in this thread, Tony Szamboti grudgingly agreed with Dave Rogers' estimate of a 2-degree tilt at the beginning of the collapse. As has been pointed out repeatedly, that much tilt smears out the jolt to such an extent that we would not really expect to see it through the poor resolution of Tony's data.Another proof for this is the Verinage demolitions. The same methodology used there shows a deceleration and velocity loss in every one of them. Nothing was smoothed out in any of those measurements.
As many here feel it is important to admit errors one has made during a debate, I have to wonder why there has been no response to my entreaty to Ryan Mackey to admit that his comments on the factor of safety and the amount of tilt in WTC 1 before it descended were in error during our debate last September.
It has been proven beyond any doubt that his comments, that the factor of safety of the central core columns in the twin towers were much less than 3.00 to 1 and that WTC 1 upper section tilted 8 degrees before the north face hinge let go, were both incorrect.
One would assume that Ryan would be professional and admit these errors, which he apparently made due to his trust in the NIST report.
If you read the Missing Jolt paper you will see that the basis for saying there was no deceleration in the fall of WTC 1's upper section is that there was no measureable velocity loss during the time it would take the velocity to recover to what it was pre-impact, over a significant period where 4 data points were taken.
You are introducing more noise here by taking a second derivative and then trying to extrapolate that a 2g deceleration could be missed. The problem for your point is that it isn't necessary to take a second derivative and it is less precise than the first derivative, which shows very clearly that there was no velocity loss.
Keep trying Dave. I was wondering today if you have a job other than posting on this forum. Do you?

Two points here. First, acceleration is the second derivative, so if you don't look at the second derivative you're not measuring acceleration. Second, even the velocity data clearly shows a drop in velocity at about 1.7 seconds, as anyone can see by scrolling up the thread; it's only because you're smoothing your data that you can't see it.
Dave
No one was burned by the enveloping cloud of dust and there was no remnant fire, therefore heat of a conventional nature can be ruled out..
So, clearly we are dealing with a force, but it obviously did things that gravity absolutely cannot do; it was inconsistent with magnetism, with radiation and with heat, as per the account quoted above from someone who was there and who experienced it.
It was DEW.
It's hard to tell whether Tony is denying the reality of arithmetic or the reality of his own data.There is never a negative slope in the velocity curve derived from the distance vs. time measurements of the fall of the upper section of WTC 1.
Dave is incorrect here when he says there was a velocity drop at 1.7 seconds into the fall. The velocity never decreases at any time and there is only a drop in the rate at which velocity is being gained. They are not the same things.

To have an amplified load velocity must actually decrease.

WORLD TRADE CENTER TASK FORCE INTERVIEW
LIEUTENANT RENE DAVILA
Interview Date: October 12, 2001
[Emphasis added.]
A. ...He goes (inaudible). I said, "Ramos?" He said, "What?" I said, "I left my wallet and my refund check in the *********** vehicle. I don't think Uncle Sam is going to give me another refund check."
Q. At this point was your vehicle lost?
A. Basically all we to do is go around the building, came around. But it took longer than usual because you're walking in like this ****.
Like you move and it's this soot like heavy dust.
While we're walking I realize that we only have two people. I see my vehicle. The seats are covered. I've still got my bag. I hold it like a trophy. Like people collect basketballs. I haven't touched -- whatever the force was, it was so strong that it went inside of the bag.
It's nice to see you've finally understood at least part of what we have been pointing out to you (that a zero acceleration still creates load), even though it took an incredible amount of explaining from many different people for it to happen. Now, if you could just understand that the load amplification is also dependent on the impact footprint, you'd be even closer to a correct understanding!

For readers who may not be familiar, the slope in the velocity curve is indicative of the acceleration and deceleration or rate of change of the velocity, with a positive slope being acceleration and negative slope being deceleration, so it is present in the velocity curve itself. There is never a negative slope in the velocity curve derived from the distance vs. time measurements of the fall of the upper section of WTC 1 …..
Tony Szamboti
The reason the Verinage demolitions show a deceleration and velocity loss is that they used the amplified loading gained with impact in a natural gravity collapse after the columns of a couple of stories in the middle of the building were removed with hydraulics to gain the required momentum.
The Verinage demolition technique removes the columns of a couple of stories to allow a drop of the upper section and to build momentum …..
.Tony Szamboti; said:I think one can say there was some pre-weakening in the Balzac-Vitry building since there were obviously three floors in the middle of the building which had been visibly modified. The demolition only pulled the columns of the upper two modified stories….
I never said that zero acceleration does not apply a load, but that it is only a static load and that is far from sufficient to collapse a structure below designed to handle several times that load.
Why do you make these silly comments? Who do you think you are kidding?
Really, Tony? This has been discussed ad nauseum in this forum, at democraticunderground, and even at Gregory Urich's forum. Don't think you can rewrite history, because there's plenty of evidence documenting your claims. The only thing silly was your contorted defense of those claims. I'm glad you've given at least one of them up, but don't pretend you never made it.
So is there difference or not between the two? What is your opinion? There is zero acceleration and then there is the other. What is your claim? Because if it is zero then you have zero as far as your beliefs go.
Do you type very slow? It takes seconds to read your real-cd-deal and label your 911 scam a delusion. You also lack a reality based physics background and need to review E=mgh. Missing jolt, is more like a missing education used practically. Is the job attack all you have to support your real-cd-deal. lol, 8 years and you still type slow and think it takes time to respond to your failed ideas on 911....
Keep trying Dave. I was wondering today if you have a job other than posting on this forum. Do you?
Yup. Same load it always was. Nothing magical. Nothing out of this world. Falling from a dead set position does not equate picking the top of the WTC up with the hand of God and dropping it. That's not what happened. In fact that wouldn't have even been enough to do what was witnessed anyway. It was just sitting there like it always had been. Even if one corner had failed, and then the rest of the corners failed because of that first failure, it wouldn't have been as uniform of a collapse that was witnessed. How instantaneous do some of you people think that kind of failure happens all the way around without incendiary assistance or explosives? Really?
My bolding
Wrong -TS’ own data (W.D.Clinger’s velocity vs time chart) shows this negative slope therefore deceleration occurred (assuming TS data) therefore the Missing Jolt paper based on no deceleration is wrong.

The difference is between what Tony now claims he said, and what he really did.
I hope these engineers don't work on anything taller than a sofa.Every engineer I talk to at work about this believes there should have been a deceleration, if the collapse of WTC 1 was due to natural forces.
And yet all objects in the solar system still revolve around the sun somehow...Gravity is an incredibly weak force
Gravity is an incredibly weak force and could not have accounted for the destruction of the lower 80 floors of the the South Tower and the lower 95 floors of the North by the small fraction of floors above them.
I try not to call anyone a liar unless it is very warranted. In this instance here you are lying.
I never said what you purport. I have said that zero acceleration does not allow for load amplification, but that isn't what you are saying.
It is possible that the problem may be your lack of understanding and maybe you aren't intentionally lying. However, either way you aren't telling the truth.
Tony Szamboti said:If the upper block only decelerates at 1g then the force applied is equal to the static load. If it decelerates at less than 1g then the force applied is less than the static load. Remember F = ma.
In order to get an amplification the deceleration needs to be greater than 1g.
If the deceleration were 2g then the force applied would be twice the static load.
See, Tony used to think that a body had to decelerate at 1g in order to produce a force equal to the static load. This is incorrect. We corrected him - multiple times, across multiple forums. Now he thinks he can pretend he never made that claim.
Not even six months later and you're claiming it didn't happen. Thank goodness JREF still has the post available.
For those who need a little help, here's the post:

You are still 1g off.
I was speaking of deceleration from full gravitational acceleration or a relative 2g deceleration there and what I said was correct. In other words a deceleration from +1g to -1g would cause the load to be 2x that of the static load. If it had decelerated at 1g from full gravitational acceleration then it would have zero acceleration and would apply the same load as the static load, and if it had decelerated at less than 1g from full gravitational acceleration the load it would be applying would be less than the static load.
If you did understand what I said there then you are obviously nothing more than a word twister. The only people you would impress with your deceptive word twisting are those who aren't knowledgeable in the area, as it is apparent you can't contribute much to the discussion and can't discount what I am saying.
So what, he is off by 1g, what is that among thruthers?![]()
He does not understand gravity, or he thinks a WTC floor can hold more than 25,000,000, or was it 29,000,000 pounds. Just placing a certain weight on a floor in the WTC will fail the floor. CD delusions are hard for the fringe few to drop in favor of reality.You are still 1g off.
If you examine this part of your newly edited word salad, you will find that the same object is both decelerating at 1g, and have zero acceleration, both at the same time.If it had decelerated at 1g from full gravitational acceleration then it would have zero acceleration and would apply the same load as the static load,
I'm almost to the point of giving up on Tony. I don't know why he can't see what is quite obvious to everyone else, even non-technical people.
Yes, I am impressed with me too.![]()
