Discussion on Building Collapse Physics

Something of this kind is what we should have seen

when the top section of the

towers collapsed onto the lower one.

The upper and lower sections should have mutually destroyed each other until all

the energy is dissipated and the system comes to a rest.

What could not have happened is this.

A little tiny chunk of the building can't possibly fall

and crush the entire structure below it.

This is such a simple, fundamental concept that architects

and engineers were

astonished in seeing it totally ignored by NIST.

This is high school physics, and our whole society is

being led to believe that these fundamental laws of physics,

hard science,

don't apply anymore.
