Amidst the break down of the Zuccotti park Occupy Wall Street encampment, other tremors to the collective psyche are reverberating around our nations’ universities. Two events are set to discuss the science of the destruction of the three WTC towers on 9/11 this week.
The first being held at the University of Chattanooga at Tennessee entitled, “The Science of 911: What is the forensic science of investigating a disaster?” The second event features Professor Niels H. Harrit of Copenhagen University and the title of his lecture is “The Collapse of the Seventh Tower: A Physical & Chemical Analysis.”
Both events feature experts from an array of related disciplines including: Niels H. Harrit Ph.D. Chemistry University of Copenhagen Jim Hall, former National Transportation Safety Board Director. David Johnson, Ph.D., Professor Emeritus of Planning, UT-Knoxville, Edwin Foster, Ph.D., Professor Emeritus of Civil Engineering, UT-Chattanooga, Tom Junod, Journalist, Esquire magazine, Felicia McGhee Hilt, Department of Communications, UT-Chattanooga, Moderator.
Abstract: To most people, the image of the World Trade Center (WTC) is confined to the famous twin towers, which dominated the New York skyline until September 11th, 2001, when they collapsed after each one being hit by an airliner. However, the trade center was an assembly of seven buildings around a plaza. The youngest of these, WTC7, was a huge office building, reaching 186 meters and 47 stories into the air. The ground-plan area was little less than a soccer field.
WTC7 was not hit by an airliner. Still, it collapsed seven hours after the twin towers in a totally symmetric movement with free-fall speed. It was the most unexpected collapse in the history of modern building construction.
The talk outlines the factual circumstances around this event. These facts are held up against the official account of the event as it has been presented in a report from National Institute of Standards and Technology. According to this report, WTC7 collapsed due to fire. But never before – or since – in history has a steel-framed high-riser collapsed due to fire.
In the second part of the talk it is proposed that the collapse of WTC was due to controlled demolitions using explosives. In addition, unambiguous evidence points to the use of thermite, which is an energetic material used to cut and weld steel. The newest findings in the dust include still-reactive remains of so-called nano-thermite.
