A
member of both the American Association of Physics Teachers and
Architects and Engineers for 9-11 Truth, Chandler has a BS from Harvey Mudd College, Claremont, CA (emphasis in physics and engineering). His MA in education is from
Claremont Graduate University, and his MS in mathematics from Cal Poly, Pomona. He has taught physics, mathematics, and astronomy at K-12 and Jr. college levels. He is also an author and served formerly on the editorial board of The Physics Teacher, an AAPT journal. David is also an active designer and inventor of educational materials emphasizing quantitative visualization.
Chandler is the producer of several videos for AE911Truth. His measurements of the fall of WTC 7 isolated a 2.25 second period in which the exterior facade fell at a rate indistinguishable from
freefall speed. He uses this as a sign that NIST is lying in its reports, but NIST has actually used this to further verify their computer modeling.
