Throw up some fancy complicated math that few people can wade through. Throw Newton's 3rd Law out the window and claim that it is correct. So the mystery is why so many people with degrees who supposedly know physics let this BS go on.

Psikey. You also do not know physics, you have proven this by showing your terrible work and presenting it as if it contained any rigour. As I explained to ANOK in my previous post. My own results show that indeed the top block experiences a progressively lower force, even though it is set to the weakest possible state.
Produce your own results that show differently, or accept that the compacted rubble layer protects the upper block. It is trivially provable but both of you seem intent on ignoring it because it disagrees with you.

So where is your PHYSICAL MODEL that can be repeatedly built which behaves the way you say? Physics does not really give a damn about mathematics or the egos of people who claim to do complicated mathematics.
Let's see the EXPERIMENT. TEN YEARS and no engineering school has built a model that can completely collapse. I am not even aware of any that has tried.
So we are supposed to fall for this "Emperor's New Clothes" game with mathematics from Bazant and his cult followers. You're too stupid to do the math. All of us geniuses understand it. We just can't make a physical model do it. Computers can do the Garbage In Garbage Out games though. Like Purdue's impact simulation where the core columns don't move even though the NIST says the south tower was deflected by the impact. And the NIST can make computer simulations that don't look like what happened to WTC7 from the outside.

No you proved it by showing your code which didn't match reality in anyway, and showing that despite your complaints and claims, you've done no work to advance the understanding of the physics of the WTCs.
You've done nothing but complain and write a terrible model, and are now complaining that I am calling you out on this.

I don't have 1300 feet of vertical space to reproduce the required gravity acceleration. Have you added a gravity acceleration phase to your model yet? I doubt it.

Because there are few as ignorant but as arrogant as you appear to be. Building scale models is sometimes a valid engineering exercise, demanding that someone rebuild a miniature WTC to satisfy your fantasies is not valid, nor rational.

That's right psikey. Despite the fact that your model was some of the worst code I've ever seen, and didn't remotely accurately reproduce the physics or the facts of the day. You are now attacking actual engineering groups like NIST and Purdue because their results disagree with yours.
It's nonsense, you're appointing yourself the most expert physics expert in the world, and trying to dismiss anyone who says you're wrong. This despite the fact that you published the details of your own model and it was woefully inadequate.
How about you try admitting that the top collision forces are significantly lower than the lower collision forces, and that even with the minimum strength for the upper section, the 'upper block survival' is still modelled in such a simple system.
Show me your code that disproves this effect. I'm eagerly waiting.

You said you got 11.6 seconds with the impossible magical conditions and yet some sources say the north tower came down in 11 seconds. As far as I am concerned you demonstrated my point. How could supports that held up the building for 28 years be crushed from the top so fast?
The simulation was MAGICAL not real. Now you want to attack me on the grounds that it "doesn't match reality" when I said that in the first place. No code matches reality. It is just a matter of being useful.
How could a real building come down in anywhere near the computed time from code based on nothing but the conservation of momentum?
But you haven't BUILT A PHYSICAL MODEL that can completely collapse and neither has anyone else in TEN YEARS. So 9/11 is a kind of Psycho-cultural fixation. If you don't believe in it then you must be stupid, but the experts don't have to supply accurate data about it. It's the 9/11 RELIGION.

What happens if most people decide 9/11 is a bunch of crap and that most people claiming to know physics went along with it but then didn't apply any experimental science to test it for a decade? Science is whatever the people claiming to be smart say it is.

No, I didn't claim to have written a great model. I just reproduced yours minus any obvious errors. It's not a great model, it's a very poor model as I have repeatedly said, but even this poor model exposes fundamental truths about an accelerating body. I notice that you can't bring yourself to accept it despite the figures being in front of you and your model supposedly able to reproduce it.
Which is it? Does the upper block experience significantly lower forces than the rubble layer and the lower block, or doesn't it? You can presumably answer this without paragraphs of hyperbole.

I never treated them as just two blocks. Bazants crush-down, crush-up is nonsense.
It is not just about forces it is about the strength of the blocks. Bazant's nonsense would have us believe that the upper block was a lot stronger than the lower block.
My magical collapse gives the blocks NO STRENGTH. The collapse time is determined by the Conservation of Momentum only. So why does it take slightly longer than what is reported for the real building?
So where is your code and data?

No it wouldn't. I didn't assume anything about such a thing but the energy loss is drastically different.

I have already explained this and posted my data and requested something from you.
You're not even reading are you?

Not to mention, his zero credentials in physics and doubtful meaningful training in physics whatsoever. I've asked the guy quite a number of times what his background in physics is and he steadfastly refuses to answer, which tells me the guy probably just read the definition of "conservation of momentum" on the Internet and he now fancies himself to be another Stephen Hawking.
I for one am tired of this guy hijacking every forum here and steering it off into insipid arguments over junk physics he himself has no understanding of.

412.0896 is that meters to the top?
Does that mean all of your other altitude and height numbers are off?
It's really cool the way you took it out to 4 decimal places. Very precise.

There isn't anything remotely comprehensible about your junk physics. I watched your videos and you try to pass off a structure with solid paper rings as an analogy for the design of the towers and how the floors collapsed, and you pass off a two demensional structure as an analogy for how much a three demensional structure swayed after an impact. Confusion over your junk physics isn't even limited to me- I saw the comments the viewers left on Youtube and none of them could make head or tail out of what you're trying to claim either. Plus, you obviously see the criticism you're encountering with your Python program.
I've asked you what your background in physics is but getting a straight answer out of you is akin to nailing jam to the wall. Will you at least admit where you originally learned the definition of "conservation of momentum" from?

In this simulation we remove all structural integrity from the whole upper section and still get a realistic time. Your point has not been proven at all, in fact we've shown that even with single floor failures, a collapse is still possible in an extremely short time.

Masses floating in air held up by nothing come down in slightly more than what the real building is supposed to have done and you call it REALISTIC.
The top block could not have remained intact and forced down everything below in less than 12 seconds
If it's possible then why hasn't anyone built a physical model that can do it in years?
All of the components of the building were subject to the same forces of gravity but they were also designed to resist those forces hence the towers stood for 28 years. So how could the falling top block overcome that strength so fast.
My program is intended to show the minimum collapse time with no strength. So a real building would have to take significantly longer unless something was eliminating those supports.

It is not an analogy to the towers. Thinking in terms of analogy is DUMB.
It is a vertical self supporting structure which is what the towers were. It is not a tube-in-tube structure which would be much more difficult and expensive to build especially without accurate data on the towers.
It is not my fault that you regard anything that is beyond your comprehensions as junk. Explain what is stopping you from building a structure that can be completely collapsed by its top 15%.
