Profound Implications of the Observed Downward Acceleration of the North Tower -- Article by David Chandler Published

The editors of the Journal of 9/11 Studies are pleased to announce publication of the following peer-reviewed article in the February 2010 volume of the Journal:

Destruction of the World Trade Center North Tower and Fundamental Physics
By David Chandler

Physicist David Chandler continues his insightful analysis of the destruction of three WTC skyscrapers on 9/11/2001 in this very readable paper. From the summary:

Acceleration + Serendipity

This is a study of the overall downward acceleration of WTC1, the North Tower of the World Trade Center. During this investigation it was discovered that the one feature that kept pace with the original acceleration of the roofline was the leading wave of ejections on the west wall.

David Chandler- Visalia Friends Meeting-Dec.17, 2009

David Chandler is the author of numerous online videos that analyze the
collapse of the World Trade Building from the point of view of a
physics instructor. David’s contributions to the NIST final Report on WTC 7
led to their admitting to 2.2 seconds of “free fall” in the buildings collapse.
David is also the author of the popular internet site: http://www.lcurve.org/
about US income distribution.

Steven Jones and Frank Greening (and others) correspond - April-May, 2009.

(From Steven Jones...)

For years, Frank Greening has argued with our research group, which is not in itself unwelcomed because we welcome review of our research. Here I will refer to recent arguments by FG and our responses, to let the reader decide for himself whose “side” has the greater scientific veracity. There are two main categories in this discussion: 1) Newton’s Third Law as applied to WTC Towers and 2) Discussion of the red/gray chips paper.

1) Newton’s Third Law as applied to WTC Tower

On April 19, 2009 F. Greening wrote to me and I replied:

FG: "I would say that Chandler's slight of hand is the implied notion that Newton's 3rd Law is universally applicable, even to a collapsing building. The fact is that when a building is collapsing by multiple floor failures the reaction force obviously fails to balance the downward force because the yield strength of the failing columns is being exceeded."

SJ: No.  This is a blatant and fundamental error.   I have caught many a student on the equivalent of this nonsense, as I taught Newtonian Mechanics for over 21 years.  Newton's 3rd law is always applicable, even in the case you mention, Frank. The key is that the "equal and opposite forces" must act on DIFFERENT bodies.   Suggest you consult a basic physics or mechanics text if you don't understand that. – Steven Jones

Later the same day, FG persists in his misunderstanding of Newton’s Laws and says:
