Physicist's analysis of Zapruder film of JFK assassination

Received this link via email from the American Association of Physics Teachers:

To commemorate the 50th anniversary of the assassination of President John F. Kennedy, AAPT is making Nobel Laureate Luis W. Alvarez's report, "A physicist examines the Kennedy assassination film," about the physics of the Zapruder film freely available to the public.


This is an old article (1976) that may nevertheless be helpful to those interested in the assassination. It's more about physics than "theories" about the event, and takes a consistent "just the facts" tone that does include disputing some of the Warren Commission's work.

How do you get to the full article? I can only get the abstract? n/t truth2power Nov 2013 #1

Its on youtube from 2005. This republican watergate burglar finally confesses and lays out the entire chain of command which included LBJ and J Edgar Hoover in cahoots with the usual suspects.

if he actually knew anything about the JFK murder. It's much more likely that EHH would babble a big buncha sh*t in the hopes of getting a chuckle from watching everybody waste time trying to verify his babble

You are wrong. Watch the video. His son who is a democrat was reconciling with him after years of covering for him such as tossing guns and evidence off a bridge for him as a child. E Hoeard Hunt was your typical G Gordan Liddy type A right winger but he saw that decades towing the party line as a bag man got him nowhere in the end but consumed by loss, bitterness and anger. He was a Watergate burglar and CIA operative yes but he is confessing in his old age and giving up his superiors. This is the biggest news of the last 40 years given his high rank as an insider. The equivalent would be Bush Sr admitting to killing RFK.

https://en.wikipedia.org/wiki/Luis_Walter_Alvarez

Flying in the B-29 Superfortress The Great Artiste in formation with the Enola Gay, Alvarez and Johnson measured the blast effect of the Little Boy bomb which was dropped on Hiroshima. . . .

Alvarez proposed in 1965 to search the Egyptian pyramids for unknown chambers. Using naturally occurring cosmic rays, his scheme was to place spark chambers, standard equipment in the high-energy particle physics of this time, beneath the second pyramid of Chephren in a known chamber. By measuring the counting rate of the cosmic rays in different directions the detector would reveal the existence of any void in the overlaying rock structure. . . .

In November 1966 Life published a series of photographs from the film that Abraham Zapruder took of the Kennedy assassination. Alvarez, an expert in optics and photoanalysis, became intrigued by the pictures and began to study what could be learned from the film. Alvarez demonstrated both in theory and experiment that the backward snap of the President's head was fully consistent with his being shot from behind. He also investigated the timing of the gun shots and the shockwave which disturbed the camera, and the speed of the camera, pointing out a number of things which the FBI photoanalysts either overlooked or got wrong. . . .

In 1980 Alvarez and his son, geologist Walter Alvarez, along with nuclear chemists Frank Asaro and Helen Michael, "uncovered a calamity that literally shook the Earth and is one of the great discoveries about Earth's history." ... Alvarez had access to the nuclear chemists at the Lawrence Berkeley Laboratory and was able to work with Frank Asaro and Helen Michel, who used the technique of neutron activation analysis. In 1980, Alvarez, Alvarez, Asaro, and Michel published a seminal paper proposing an extraterrestrial cause for the Cretaceous-Tertiary extinctions.
