Scientists for 9/11 Truth Roll-out Press Conference at Los Angeles City Hall


5th Annual 9/11 Physics Debate  The Association for Nine Eleven Truth Awareness (ANETA) hosts an annual “Physics of 9/11” debate in which physicists or physics professors are invited to support the official story in a debate with a physicist or physics professor from the 9/11 Truth Movement. In the 5th annual debate David Chandler was invited to represent the position challenging the official story and (as has been the case each year so far) no one stepped forward to represent the official story. Hence the “debate” becomes a discussion. The 5th annual “discussion” seen here focuses on the collapses of WTC 7 and the North Tower.


My Response to Chris Mohr’s rebuttal to Richard Gage on the collapse of World Trade Center Building 7. (The video being discussed was removed from YouTube by the owner.)



[I recently discovered that Chris Mohr remade the video critiqued here, changing words around to avoid my specific criticisms.  Toward the end he actually acknowledges his previous (very fundamental) misunderstandings but doesn’t recognize why that should disqualify him as a serious critic of the demolition hypothesis.  See it here.]




Individual Analysis Videos (most recent at the bottom)

Race with Gravity


THANKS TO  911SpeakOut.org




Video analysis, using Physics Tool Kit software, of the speed of the demolition wave moving down a face of the North Tower in comparison with the rate of freefall through air of heavy material nearby. (Acceleration + Serendipity is a more updated treatment of the same phenomenon.
(Analysis based on the BBC footage which can be seen in full here.)


The Terrorism Scam
This You-Tube video is a commentary piece about the virtual non-existence of a US terrorism threat. Yes, there is such a thing as terrorism, but it is adequately covered under the heading “murder.” Making it a special class of threat is an emotional appeal that induces fear and makes the population willing to give up civil liberties and even violate human rights. In the case of terrorism, the cure is worse than the disease.


North Tower Exploding
This is an narration of a video clip of the North tower which focuses on explosive ejections progressing in waves down the faces of the building. Among other things it is a response to theories that postulate causes for the collapse that ignore the evidence that can be easily seen by anyone in the video footage itself. Observation is the foundation of science.


WTC7 in Freefall–No Longer Controversial
The previous analysis of the freefall acceleration was criticized (legitimately) for using a horizontal calibration measurement for analyzing purely vertical motion. Any distortion or stretching of the video could throw off the measurement. In this new video, the calibration utilizes NIST’s data for the heights of the roofline and the 29th floor to do a vertical calibration. The result is a measurement even closer to idealized freefall: 9.88 m/s^2.


[Another video maker, “skeptic121” who wishes to remain anonymous, has posted a similar measurement using a different video and using a different technique. It contains interesting comparison measurements from other collapses as well.]


WTC7: NIST Finally Admits Freefall (Part I)
In its draft report, released in August 2008, NIST attempted to cover up evidence that WTC7 fell at freefall, but the coverup was transparent. In its final report, released in November 2008, NIST finally acknowledged freefall, but couched it in a bizarre framework that continues to deny its clear significance. This illuminating video displays the brazenness of the NIST WTC7 coverup. John Gross, one of the lead structural engineers for the NIST investigation, who figures in this video, has established a reputation for lying and evading evidence. (Another example of John Gross’ evasive interaction with questioners on other a different key piece of evidence.)


NIST has removed the video of the press conference from their web site. Here is an un-edited video clip of the parts dealing with the questions from David Chandler and Steven Jones. (Also, here is a transcript of the whole briefing.)


WTC7: NIST Finally Admits Freefall (Part II)
This is not the “Part II” I had originally envisioned. That will have to wait for Part III. In following up on the erroneous measurement described by John Gross in Part I, I decided to look more carefully at the measurement and find the video frame NIST claims marks the beginning of the collapse. What I found is that there is no motion of the roofline for at least 20-30 video frames after the point identified by John Gross. In other words, the measurement is a complete fabrication with the goal of producing a “measurement” to agree with the result predicted by NIST’s collapse model. This result is sufficiently significant to merit its own video.
…More to come in Part III


Clocking WTC7: A more recent supplement to Part II that graphically shows the NIST timing fraud.


WTC7: NIST Finally Admits Freefall (Part III)
Part III fully explores the implications of NIST’s admission that freefall occurred and critiques the foundations of their “investigation.” In the end it calls for a new, independent, fully empowered, and open investigation.


[The WTC7 series has elicited a number of questions from people unclear on the details of how I did the measurements, compared to how NIST did them and how the representatives of NIST described their measurements. I have therefore created a WTC7 Measurement FAQ page. I will also use this FAQ as a place of reference for other questions that arise as well.]


Downward Acceleration of the North Tower
The roofline of WTC1 (The North Tower) begins dropping with sudden onset and accelerates uniformly downward at about 64% of the acceleration of gravity (g) until it disappears into the dust. This means it is meeting resistance equal to about 36% of its weight. The implication of this, however, is that the force it is exerting on the lower section of the building is also only 36% of the weight of the falling section. This is much less than the force it would exert if it were at rest. The acceleration data thus prove that the falling top section of the building cannot be responsible for the destruction of the lower section of the building. The complete analysis of the phenomenon illustrated in this video is published in a paper called Destruction of the World Trade Center North Tower and Fundamental Physics, Journal of 9/11 Studies, February 2010.


[I want to acknowledge the work of Graeme MacQueen and Tony Szamboti who have been engaged in similar measurements by other means and have reached similar conclusions.]


South Tower Smoking Guns
This video narrates a collection of diverse phenomena in the debris cloud of the South Tower that point to explosive demolition. Particularly notable is one projectile (which I have not seen discussed previously) that is shooting to the east, then stops, midair, then turns a sharp corner and shoots straight down trailing white smoke. White smoke is characteristic of aluminum oxide which is a byproduct of the thermite reaction.


South Tower Smoking Guns (Follow-up)
After finding the projectile that turns a sharp corner while trailing white smoke (which I have dubbed the “Angle Rocket”) I looked for it in other videos and found it in several. The clearest is from a camera with a very similar perspective to the first, but in this video the trail can be followed to the bottom of the collapse. Here I explore the significance of this find.


South Tower: Exploding Projectile
A close-up view of debris being ejected from the South Tower of the World Trade Center as the 30-floor top section falls to the east shows numerous smoking projectiles that look like comets. Several of them can be seen to explode. One such exploding projectile is followed here. It ejects two fragments, both of which undergo secondary explosions. (Note, the rising fragment to the left of the projectile under consideration appears to be a tumbling object that alternates from black to white to invisible. It passes behind one of the fragments described in the video.)


Cutter Charges in the North Tower of the World Trade Center
Small explosive ejections focused on a corner column of WTC1 (The North Tower of the World Trade Center) are evidence of cutter charges used to cut the corner columns. One of these occurs at the 98th floor at the onset of the demolition of the building. The other occurs lower in the building at the instant the column enters free fall.


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 a wave of ejections on the west wall.


High Speed Massive Projectiles from the WTC on 9/11
I have revisited and extended some of my early measurements of high speed massive projectiles from the World Trade Center on 9/11. The results for the three projectiles measured: 56 mi/hr, 45 mi/hr, and 78 mi/hr. I don’t claim this is smoking-gun evidence of explosive demolition all by itself, but it is part of the puzzle and it is more compatible with the explosive demolition hypothesis than simple gravitational collapse.


(On a technical note, if you are looking at the numbers in the three measurements, the third measurement is taken while the video was zoomed in, relative to the calibration frame. The numbers shown have to be scaled down by a factor of 1.701 to give the stated results.)


WTC 7: Sound Evidence for Explosions
There is ample evidence, from both witnesses and recordings, of explosions associated with the destruction of World Trade Center Building 7 (WTC 7). NIST sidestepped investigating explosions and explosives by setting up an artificially high threshold of interest. They swept aside any testimony or recordings of explosions that would not register 130-140 dB one kilometer away. They established this criterion using RDX (one of the loudest explosives) in a scenario that produced a far higher sound level than other possible uses of explosives to bring down the building. Then they turned around and used sound level as the sole criterion for deciding whether the use of explosives was a credible hypothesis. By this maneuver, they sidestepped investigating testimony of explosives or possible evidence of explosive residues. This is just one more instance of fraudulent behavior on the part of the NIST investigation of the World Trade Center disaster.


What a Gravity-Driven Demolition Looks Like
The official story is that the North Tower of the World Trade Center collapsed due to gravity. This has been critiqued in an analysis by Graeme MacQueen and Tony Szamboti, and in a related analysis by David Chandler (both in the Journal of 9/11 Studies). The Balzac-Vitry demolition was a true gravity-driven collapse. The same analysis that was applied to the World Trade Center is here applied to this known demolition, with contrasting results. This analysis supports the conclusions of both papers referred to above: the North Tower of the World Trade Center was not a natural, gravity-driven collapse.


Rockets at the World Trade Center
Some of the debris from the South Tower at the World Trade Center shot downward faster than gravity. This is literal, visible proof of explosive materials painted onto perimeter wall units.

Wayne Coste

Why We Expend Energy on Proving Large Plane Impact at the Pentagon

Explanation of the Evidence at the Pentagon on 9/11

Created by Wayne Coste, narrated by David Chandler



Introduction and Summary

In December 2017 the 9/11 Consensus Panel issued a statement addressing the controversy

within the 9/11 Truth Community about what happened at the Pentagon. The concern was that

the disagreements in this area threaten to undermine good will and mutual trust. The statement

offers the prescription, “Contributions seeking to solve contentious issues can only be made

by assembling reliable evidence and by applying critical thinking and peer review according

to the standard scientific process. This is the strength of science and the way it has progressed

over centuries.” and concludes, “In conclusion, we offer the “agree to differ” approach:

to end an argument amicably while maintaining differences of opinion until there

is an explanation that does justice to all the various types of evidence.”


Over about a three year period Wayne Coste has been engaging in dialogue with some

of the leading contenders for theories alternative to large plane impact and has been assembling

a comprehensive compilation of the evidence that any successful theory must answer.

When he read the Consensus Panel’s statement he saw it as a challenge that he had

largely already met. He pulled together his research and assembled it as a single presentation

entitled, “Explanation of the Evidence at the Pentagon on 9/11.” He re-framed this as

“Answering the 9/11 Consensus Panel Challenge.” He turned the Powerpoint into a video,

with the downside that the running time was a virtually unwatchable 5h 40m. He just wanted

to “get it out there.” I saw the tremendous value of this body of work, so I stepped in and

offered to narrate the video as a more manageable series of chapter-by-chapter videos.


The work is extensive, so the video series is lengthy.  To help navigate the scope of the

issue we have compiled a short video summary of the primary findings.  The summary is

keyed to the “chapters” of the video series, so you will be able to easily navigate to the

sections of most interest if you don’t want to invest the time to work through the whole

series all at once.



Video Summary

Bitchute / YouTube

[One puzzle with regard to large plane impact is the survival of the second floor segment

of Column 14, seen in the middle of the second floor opening in the composite photograph

shown above.   From the view shown above, it appears to be intact and vertical.  Wayne Coste

has investigated the condition of that column from another angle and found that it is neither

intact nor vertical.  It is broken off at the bottom and hanging at an angle consistent with the

top of the fuselage hitting a few feet above the second floor slab.  See the new analysis here.]


Full Video Series

Chapter 0: Preface

Bitchute / YouTube

The focus of these videos is on the question, “What mechanism caused the damage at

the Pentagon on 9/11.” As Wayne says, “If you care enough to have an opinion about

what happened at the Pentagon, you should care enough to know what the evidence is

and what it shows.” Many discussions have focused on specific details in isolation, have

ignored or misrepresented vast amounts of evidence, or dismissed evidence on flimsy

grounds. This kind of comprehensive treatment is important because an incomplete

understanding of the event leads to erroneous conclusions. It is important that we present

reasonable accounts of the evidence if we want to be taken seriously by the public.



Chapter 1: Overview
Bitchute / YouTube

What we can all agree on; what will not be considered; Consensus Panel treatment of

the Pentagon issue; overview of the geography of the Pentagon and its surroundings;

the structure of the Pentagon.


Chapter 2: Endless Pentagon Debates; How Did We Get Here?
Bitchute / YouTube

The history of the ideas (not the personalities), asking how we got stuck in the heated debate

we have today. Thierry Meyssan’s “The Frightening Fraud”; the “16 foot hole” meme;

“Missing Wings”; “Loose Change”; “In Plane Sight”; the “reinforced concrete” meme;

Dodgy Dodds; “The New Pearl Harbor” (movie); persistent claim that “evidence is Photoshopped.”



Chapter 3: Size of the Opening in the Pentagon
Bitchute / YouTube

The persistent “hole too small” error; structure of the outer wall of the Pentagon; nature of

the “blast resistance” upgrades to Wedge 1; blast resistant windows, not blast resistant walls;

the 96 foot opening in the first floor; evidence from composite photographs; detailed examination

of missing or damaged columns; specific contentious damaged columns; the 18 foot opening in the second floor.



Chapter 4: Design, Construction and Destruction of E-Ring Wall
Bitchute / YouTube

Design, construction, and destruction of the E-Ring exterior wall; misleading and downright

false information that has persisted in discussions over the years; response to the 1996

Khobar Tower bombing and the issue of flying glass; total lack of reinforced concrete;

collapsed wall photos as evidence that the actual construction matches the documentary descriptions.


Chapter 5: The Tree at Column 16
Bitchute / YouTube

Did you realize there was a tree at the point of impact? It has almost never been mentioned

in the Pentagon discussion. What happened to the tree and where it is

found in the rubble tells us something about the nature of the event.



Chapter 6: Review of the C-Ring Exit Hole at the Pentagon
Bitchute / YouTube

Nature of the hole; how heavy debris could travel from the impact point

to the exit hole; structure of the C-Ring wall; distribution of debris.



Chapter 7: Plane Approach Path
Bitchute / YouTube

Evidence for the path of the plane: radar, FDR, eyewitnesses, physical damage; impossibility

of the CIT north path; notch in the tree by the overpass; light pole damage; g-forces for

the plane to pull out of its dive; the consistency of all the various lines of evidence.



Chapter 8: Plane Impact Analysis
Bitchute / YouTube

Generator trailer damage (right engine); retaining wall gouge (left engine); yaw rotation due

to engine impacts; interaction with the cable spools; detailed progress of impact of the left

and right wings and the affected columns; where the tail went; locations of the spools before and after impact.



Chapter 9: A Comprehensive Review of the Lloyd England Accident Scene
Bitchute / YouTube

Lloyd England’s taxicab is evidence that the downing of the light poles was a real-time

event that could not have been staged ahead of time. This single piece of evidence therefore

discredits any theory that eliminates a large plane flying along the path of the downed light

poles. CIT responded by interviewing Lloyd England and accusing him of being an accomplice

to the staging of the scene based on supposed contradictions in his story. This section

examines all the fragments of the first two light poles and determines which piece actually

hit the taxi, providing in a factual basis for evaluating Lloyd England’s story.



Chapter 10: Analysis of the CITGO Security Cameras
Bitchute / YouTube

One of the security camera videos that was released is the camera at the CITGO gas station,

between the Pentagon and the Navy Annex. The images are low resolution and taken at

one frame per second, but there is a single frame that captures the shadow

of the incoming plane as it passes just to the south of the station.



Chapter 11: Pentagon Security Camera Analysis
Bitchute / YouTube

Two closely spaced security cameras, recording at one frame per second, captured the

plane as it crossed the lawn. These images have been attacked by some as having been

Photoshopped to show the plane. This section evaluates the differences in the two videos

and assesses their authenticity. The two videos were combined onto a single recording device,

so the frames are necessarily staggered. Internal evidence is used to measure the time

lag between the two sets of frames, and the resulting calibration is used to derive a measurement

of the speed of the plane, independent of assumptions from any other sources. The

resulting speed measurement is in good agreement with the radar and FDR data.



Chapter 12: Debris
Bitchute / YouTube

Debris expectations; the Sandia F-4 crash test; the outside debris field; distribution of debris;

mechanism for spreading light vs heavy debris; evidence for a trailing air mass behind the

plane; specific debris pieces of note; identifiable airplane debris in the AE drive outside the

C-Ring exit hole; identification of engine parts; verification of the engine type; sifting for human remains.



Chapter 13: Evidence of Explosions
Bitchute / YouTube

Lack of definitive evidence of explosions; the fireball captured in a Daryl Donley photograph

and confirming live news footage; uplifted second floor slab; remnants of columns 15-17

pushed inward, not outward; bowed and broken internal columns; debris distribution on

lawn and outside C-Ring hole not consistent with explosions; lack of evidence for explosions

initiating roof collapse.



Chapter 14: The April Gallop Lawsuit
Bitchute / YouTube

A case study in what happens when insubstantial 9/11 evidence is relied upon in court.

Doctrinaire attitudes toward the events of 9/11 do not play well in court. We need to get it right!



Chapter 15: Ground Effect and Yaw Rotation
Bitchute / YouTube

The physics of flight and creation of wingtip vortices; the nature of ground effect;

the Boeing 720 crash test; implications for the plane at the Pentagon

flying far over the recommended speed very near the ground.



Chapter 16: Porter Goss and the Sonic Boom
Bitchute / YouTube

The loud sound, documented by multiple recordings and mistaken by

some for an explosion is shown to actually have been a sonic boom.



Chapter 17: Citizen Investigation Team Interviews
Bitchute / YouTube

The CIT hypotheses: no impact, northern flight path, plane flew over the Pentagon; questions

about CIT methodology; comparison of CIT interviews with earlier interviews of the same

subjects; George Am; Lloyd England; Chadwick Brooks; William Lagasse;

Lagasse’s correspondence with Dick Eastman; Robert Turcios.

Articles, Links, Etc.

9/11 does not go away. It is with us on a daily basis. It has been the emotional rationale

for a long list of radical changes in US policy, many of which continue with us even

under the Obama administration:


  • a supposed “War on Terrorism”
  • actual wars in Iraq and Afghanistan
  • possible future wars against a supposed “axis of evil”
  • condoning torture and indefinite detention without any kind of due process
  • scuttling the Geneva conventions
  • the sacrifice of civil liberties at home

If 9/11 “changed everything,” as George W. Bush said, then it is extremely important that

we “get it right.” What really happened that day? The administration made a rush to judgement,

immediately destroyed much of the evidence, stamped much of the remaining

evidence “Secret,” and implied that critics were “with the terrorists.”


If all you know is what you have read in the papers or seen on the TV News, you are not

fully informed, and you are quite possibly misinformed. We believe you have also been

intentionally DIS-informed.


A “9/11 Truth Movement,” inspired initially by families of 9/11 victims, has amassed a

significant amount of research that casts doubt on the official story line, but many people

have never heard this or thought through the implications. The administration and the

compliant media want this issue to go away, so any attempt to discuss or speak out on

this issue is dismissed as a “conspiracy theory.” But keep in mind that

even the official story of 9/11 is a rather bizarre “conspiracy theory.”


[If you have inside information on what happened on 9/11, get a copy of the

Whisteblower’s Handbook as a guide to how to get the information out while protecting

yourself as well as possible, and visit http://nisterrors.com for assistance.]




In 2015 Architects and Engineers for 9/11 Truth published Beyond Misinformation, an

excellent overview of the evidence for controlled demolition of the World Trade Center Towers

1, 2, and 7.  More recently (2016) Europhysics News has published

15 Years Later: On the Physics of High Rise Building Collapses,” 

an overview article by Steven Jones, Robert Korol, Anthony Szamboti, and

Ted Walter, giving this information wide circulation in the science community.

Our most solid evidence for the use of explosives in the destruction of the World Trade Center


Anyone who has presented the evidence that the World Trade Center was demolished

with explosives has run into people with psychological barriers to even hearing the information.

  Psychology professional Frances Shure has explored this subject in a series of essays,

originally serialized in the Architects and Engineers for 9/11 Truth newsletter entitled

Why Good People Become Silent — or Worse — About 9/11.  (There are 20 parts to the

complete series.  A partial series is posted here for now and the others will be added

9/11…So What?  People want to know how they can respond once they have been made

conscious of the truth of 9/11.  I get that question a lot.  Here are my thoughts on that subject.

identifying carbon nanotubes in the lungs of first responders.  These are not found associated

with other building fires.  The carbon nanotubes were also found in the WTC dust.  Production

of carbon nanotubes requires high temperatures in the presence of carbon and a metal catalyst.

  These conditions are present in the combustion of nanothermite.  Kevin Ryan and

Niels Harritt have shown that combustion of nanothermite actually produces carbon nanotubes.

Analysis of the Structure of the Buildings at the WTC

Some Misunderstandings Related to WTC Collapse Analysis 

by Gregory Szuladzinski, Anthony Szamboti and Richard Johns
(That is a very conservative title.) This is a disproof of the official explanation for the

collapse of the North Tower through mechanical analysis.  Published in the International Journal

of Protective Structures.  Summary:  The energy absorbed by the buckling of the columns

would have arrested the collapse within one, or at most two, stories of the onset of collapse. 

This paper shows the Bazant papers (claiming once initiated, total collapse was inevitable) to

have fatal flaws based on unrealistic assumptions.


Overview of the WTC Collapse Analysis paper by co-author Tony Szamboti:


The energy situation in the first several stories of the collapse needs to be looked

at by separating the fall through the first story from the collision between floors


1. Constant acceleration [which we see by direct measurement] shows that the average

resistive force during the fall through the first story is equal to that which just barely allows

the initial movement and thus precludes development of any significant velocity in a natural

fall. Arrest should have occurred at the end of that one floor drop in a natural collapse.

In fact, this is a serious problem for the official story since there is no natural way to

generate a significant velocity in the first story due to heat weakening caused buckling.


2. Using actual velocity measurements, the kinetic energy available after the measured

one floor drop is not sufficient to break through the lower floor’s columns. Bazant’s

calculations show continued propagation only by assuming free fall generated

velocity through the first story, nearly doubling the mass of the upper section,

and underestimating lower section column strength by about 70%.


3. Even if somehow a significant velocity could be developed through the fall of

the first story there is no deceleration during the collision between floors, which is

necessary to generate the dynamic/amplified load to deform the columns and propagate

through the next story down (which was capable of supporting several times the static load above it).


Up to this point Bazant has not been taken to task for the first and second issues, as

earlier critiques had largely concentrated on the third. Bazant has been given a pass

concerning the velocity developed during the first story fall to be at least what was

measured, and although I had been complaining about Bazant’s extreme inflation of

the kinetic energy available and underestimate of column strength, it hadn’t been

explained well publicly.

Misrepresentation of the WTC7 Structure by NIST

Letter by Attorney William Pepper to the Office of the Inspector General of the US Department

of Commerce, which oversees NIST + A description of misrepresentations by NIST

of the structures that are key to their proposed WTC 7 failure mechanism.

Tony Szamboti and others have been investigating the mechanism NIST asserts caused

the collapse of WTC 7.  It has been discovered that in order to make their mechanism

to work, they needed to deceptively alter their description of the construction details in

several ways.  These differences show up when NIST’s description of their modeling is

compared to recently released drawings of the actual structures.  The deception is central

to an effort to challenge the NIST WTC 7 investigation on legal grounds as being evidence

of an intentional coverup. Following the letter, in the same pdf file, is an extensive discussion

of the key omissions.  This is an ongoing effort.


Modeling WTC 7
Architects and Engineers for 9/11 Truth has sponsored a major project to model the

structure of WTC 7 as a check on the modeling done by NIST.  They contracted with

Dr. Leroy Hulsey, a professor of structural engineering at the University of Alaska, along

with two collaborators, an engineering post-doc and a PhD candidate, to construct two parallel

computer models of the building and test its response to fire and other stresses that might

account for its observed behavior on 9/11/2001.  The entire process is completely open

and transparent.  The amount of detail presented might seem overwhelming to a casual

audience, but it should provide a basis for confidence in the process and the results to

anyone with technical competence who wishes to understand the issues in detail.


The September 2017 “final report” on the fire modeling and the hypothesis that fire caused the collapse

Later there will be a second “final report” dealing with issues of progressive collapse. 

Already this project has revealed that the NIST modeling was false and deceptive in many

respects.  This video has been enhanced from the AE911Truth version in that the slides

are full screen and highlighted with pointers that mimic the comments in the live presentation.

Incontrovertible / an excellent (British made) full-length, broad scope exploration of 9/11,

related events, and implications.  Most non-technical overview films have mixed good

evidence with weak evidence and/or speculation.  This one is solid.  It focuses on WTC 7,

as evidence of demolition and insider involvement, but its overall scope is very broad.  Beautifully produced.

Tools for Video Analysis

I (DC) started out doing measurements of the 9/11 videos using a tool called Physics Toolkit.

More recently I have been using a much more capable and easy-to-use

tool called Tracker, part of the Open Source Physics project.


Tracker allows you to mark multiple tracks with an unlimited number of points on a full-screen

video, and it allows you to zoom in while placing the marks. No more magnifying glass to

the screen! It also has a large collection of analysis tools. You need a little physics background

to be able to use it intelligently, but no particular background to use the software.


There may be a bit of a learning curve but if you’re interested, give it a try.  Here is a brief tutorial.


The Split

Artwork inspired by David Chandler's work


Mark Dotzler writes:

“I’m an artist and I made a piece of artwork called ‘The Split’ that

was inspired in part by one of David Chandler’s early videos.”


On his website Mark writes:  “The title ‘The Split’ has a number of meanings here, but chiefly

refers to a split with reality that occurred on that day.” (The blue Ipod screen with the “2” is

running a countdown timer program.  I love the representation of Building 7 with an old high school physics text.)

Thank you Mark.
