  1. This is how the Frontal Shooter (or lack thereof) will be determined in an incontrovertible, accurate and scientific way. Stage No. 1: It may take a few years for the science to be developed but this is the way to do it: https://goo.gl/jTy69B (SBT. This is solved with technology) https://goo.gl/da4mcQ (Head Shot. This is solved with science - See inside "Documentation" folder) The result of those projects will be the creation of an OPEN infrastructure where all the interested parties will test their hypotheses, place the rifle(s) in some location and shoot: BANG! They will be trying thousands of combinations with varying angles, distances and calibers, recording the effect of each. I predict that at that time, both the Jet Effect and the Sewer Drain Shot will be early dismissed. http://jfkfacts.org/gun-man-sewer-shooting-jfk/ Stage No. 2: The great news is that the science is already here. It just arrived. As we all know, the Jet Effect has been widely debunked. The last explanation left to the Warrenistas is the "Neuromuscular Reaction", right? I came up with the following idea. Visualize a train that starts to move in the remote distance. It has 2 locomotives, one at each end. We can watch it, film it and measure it in slow motion. The problem to solve is this: Was the train moved by the front locomotive (pulling) or the back locomotive (pushing)? The Parkland Effect posits that the head moved as if hit by a baseball bat, and therefore the chain of movement is: bat --> head --> neck --> shoulders --> torso In the Neuromuscular Effect (dismissed by all neurology specialists, but we are still obligated to study it from the point of view of Physics) the chain of movement is: neck muscles, back muscles --> head, torso (randomly, supposedly the muscles of the back are stronger). IOW: The cause and the effect are reversed. What we need to do is simulate to a high degree of precision the 2 competing alternatives. Was the Head of JFK Pushed or Pulled? https://goo.gl/6woICd As you can see, I have very few files in that repository, but a new venue has been started. The longest trip begins with one step. Next, I intend to contact the 3 authors of that research project and talk to them about using their remarkable development in the solution of the JFK murder case. Obviously, if the request came from somebody (hint: some body) more representative than "Ramon Herrera, immigrant and JFK geek" it would have more effect. Furthermore, it is my duty to inform the community about my experience in similar projects, one which has become a routine/pattern. Early on, the genius scientists (young people, mostly) are really excited about the JFK case. Soon afterwards, some wiser/prudent adult (the head of their group?) warns them, instills fear, and after that, they are not replying to my e-mails or phone calls. With people overseas I have been much more successful. -RFH
  2. Do you want to scare the hell out of Lone Nutters? It is actually pretty easy. You just have to use some fancy terminology: - "Computational Biomechanics" https://goo.gl/9w6gXC - "Finite Element Analysis" - "Computational Fluid Dynamics" - "Open Source 3D Model of Dealey Plaza" https://goo.gl/jTy69B - "Brain Ballistics" http://link.springer.com/article/10.1007%2FBF01508103 (Click on "Look Inside") To be frank, when it comes to the use of Science, both camps are still stuck -or stuck still- in the 20th. century and not even the 1990s, more like in the late 1980s. That's a bummer. :-( The bright side, however, is that the only ones pushing that boundary is us, the ones interested in The Truth. [Women and Men Working - Come back later ] -RFH
  3. [Women and men working - Come back later] Comparison of Gunshot Entrance Morphologies Caused by .40-Caliber Smith & Wesson, .380-Caliber, and 9-mm Luger Bullets: A Finite Element Analysis Study http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0111192 -RFH
  4. This should be of interest, at the very least to: - Chris Newton - Glenn Nall - Jon Tidd - Bob Prudhomme - Yours Truly - etc. I recently contacted the following scientific research organization, located in Barcelona, Spain, in order to see whether they are willing and able to perform precise simulations of the fatal shot: http://www.idrasimulation.com/brain-impact-with-alya-part-1/ Guided by the nice, helpful folks above -and as Open Source Software author myself- I was pleasantly surprised to learn that there are many applications and data which are freely available "for the rest of us": http://mcx.sourceforge.net/cgi-bin/index.cgi?action=browse&id=MMC/Colin27AtlasMesh&oldid=MMC/CollinsAtlasMesh This one comes directly, courtesy of none other than Uncle Sam himself: https://www.nlm.nih.gov/research/visible/visible_human.html But I will leave the best for the next message. -Ramon Tip: It is as hands-on as you can get.

  5. A lot of events and phenomena can be simulated. With every passing year, not only does the universe of things that can be successfully subjected to simulation grow, but the degree of the endeavor and thus the accuracy of the results improves. Let's use a dice as an example. The simplest simulation would be a one-liner program: Result = rnd(6); This assumes a perfect dice, which is not always the case. Read on... ============================================= Anecdote: When I was a child in a carnival back home, there was a "magician" with a table and some dice. After reading the rules posted behind him, I was sure that there was a way I could easily win. Soon, the fool in me was separated from his money. So, I decided to stick around and observe the M.O. of the enterprising guy closely. Sometimes, he would insert his hand inside his pocket and retrieve another pair of dice. These ones were a tiny bit flattened. You could see that the black dots that formed the numbers 3 and 4 were smaller (you probably know that the opposite sides of a dice always add up to 7, correct?) ============================================= Just to make the problem a thousand times harder, consider: - the difference in weight of the 6 faces. and a million times even harder - the effect of aerodynamics in those carved tiny holes as the dice spins around in mid-air and bounces off the table. For the impatient: With the advancements in science and technology, it turns out that simulating the fatal shot that hit president Kennedy -and thus discovering the precise trajectory of the projectile- is indeed a lot harder than my one-liner computer program above, but A LOT easier than the last dice simulation. https://en.wikipedia.org/wiki/Simulated_reality
  6. Needless to say, visual expressions that communicate the underlying science in an aesthetic manner are important. We should try to make things visually appealing. https://www.freelancer.com/contest/ReDraw-Provided-Image-in-Adobe-Illustrator-277977.html I am interested in media that goes all the way from a simple JPEG to a realistic mathematical simulation, and the above contest is a step in that direction. Technology is making possible developments that were impossible and/or not affordable. To cite an example: It is perfectly doable to recreate the full Zapruder film to the maximum level of clarity, zoom-in, zoo-out and 3D rotations. This must be done in a peer-reviewed, open environment, lest we fall in the traps by ABC and others. In addition to its owner, only God knows the content of Dale Myers' hard disk. We can do better than that mockery of science. -Ramon
  7. Folks, please take a look at the latest production of my trusted team of animators: https://www.youtube.com/watch?v=dKC_zBA50HA&feature=youtu.be What you see above is the first step toward obliterating the official version, depicted below: Look closely: the head does not move 1 cm. This has been demonstrated empirically by the other side, of all people. The supreme irony. One strong possibility is that for a tangential shot it is physically impossible to make an adult airborne. The violent move (seen not only in the Z-film) is a mathematical absurdity. The argument I am attempting is known as reductio ad absurdum. This hypothesis needs to be proven beyond a shadow of a doubt, correct?. Thank God, we have science and technology on our side. They are closer to us with every passing month and year. Indeed, we need to go from animation to simulation. What is the difference, you ask? Answer: Several zeros to the right of the dollar sign, not to mention brainpower and the participation of universities. -Ramon
  8. Folks: This is the essence of the so-called "Herrera Effect" (aka "Parkland Effect", aka "Suction Cup Effect") : (1) Minimalist, from above:https://www.youtube.com/watch?v=5oMYjHEQkEQ (2) With CFD: https://www.youtube.com/watch?v=k-G11nq5Pa4 (3) Lateral view with more realism: https://www.youtube.com/watch?v=tB6eB2lXBk8 Frankly, I am trying to decide what to do about the fate of the bullet. I wonder whether there is enough heat to vaporize it in such short trip through cranial matter. What is the official version? All one reads is "Magic Bullet this, Magic Bullet that". Can't find much about the Fatal Bullet. TIA -Ramon
  9. This is the closest simulation I have found to the frontal shot. https://www.youtube.com/watch?v=sBQNnhfZ6CY We can clearly see how the practical diameter of the "bullet" grows to the size of a baseball, fist or grapefruit. BTW: It is easy to prove the impossibility of the Jet Effect, which explains being abandoned by the WCR apologists. -Ramon
  10. Hi Greg: Kindly forward this to Dr. David Mantik. This one of the entries in a contest that I am sponsoring: https://www.youtube.com/watch?v=ulSv3M7dHO8&feature=youtu.be (I suspect that I will award the bid to them) The plan is to go all the way from a crude JPEG to the most realistic simulation of reality possible. Warrenistas will be welcome to present their hypotheses. The truth will prevail. Thanks, -Ramon
  11. On one hand, we have a 6.5 mm projectile which left an entry hole of say, 7 mm. Or, 10 mm, tops. The hole left by the missing bone in the back of the head can be determined by the eye witnesses: https://www.youtube.com/watch?v=DX58vrL5ZiA FF to minute 5. We have read or heard before: "baseball size", "grapefruit size" and "fist size", "egg size". This is the first time that I read the description used by Dr. Pepper Jenkins. To be sure: the question is not about the bullet's exit diameter (in the middle of the bone): let's accept that it was roughly the same as the entrance's diameter. I am not asking about the perforated hole (10 mm), but about the knocked out, or pushed hole. IOW: Perforated: Converted in dust, lost. Imagine a Craftman drill. Knocked Out: Picked by Harper. Well, the extremely precise answer is right here. State of the art technology allows us to reach an accuracy that was unfathomable in a good portion of the previous 50 years: https://www.youtube.com/watch?v=D6iuVr9V6os [FF to second 10, "Pressure Field"] That pressure, indicated by the beautiful color red/yellow is exactly the same size as Dr. Jenkins' palm. -Ramon
