Debunking David Ray Griffin Continued

Unless otherwise indicated, all information in this article comes from “On Debunking 911 Debunking” by Ryan Mackey.

On pages 30-32, Ryan Mackey provides us with David Ray Griffin’s comparison of the ‘88 First Interstate Bank fire in L.A. That fire lasted for 3 ½ hours and destroyed five floors, but the structural damage was negligible.

However, there are several differences which Griffin ignores- fortunately, Ryan Mackey provides the differences, and those differences were as follows:

There was no loss of fireproofing, unlike the WTC
There was considerably less ventilation, and therefore less oxygen for the First Interstate Bank fire, unlike the WTC, where the impact of the planes left gaping holes in the side and broke windows
The LA Fire Dept was able to fight that fire as it started on a fairly low floor and the elevators were still functional, and
The First Interstate Bank more than likely started at a single location and spread slowly rather than starting across multiple floors at once

Real Physics vs Wile E. Coyote Physics

» by Victor Chabala in: FHK/General

(Picture from here)

Continuing from my previous article, here are some more real world physics for “truthers,” as opposed to the Wile E. Coyote physics they use.

As I pointed out in my previous article, mass doesn’t move mass, force does, and , per Newton’s Second Law of Motion, Force equals mass times acceleration, written as F = ma (source). Force is measured in Newtons (reference). The same source gives this definition of a Newton: “One Newton is defined as the amount of force required to give a 1-kg mass an acceleration of 1 m/s/s.” 1 m/s/s is another way of saying 1 m/s-squared. This means that a one-kg mass would have a force of 10 Newtons (N). Continue Reading »

Another Real World Physics Lesson for “Truthers”

» by Victor Chabala in: FHK/General

It’s time to give “truthers” another lesson in real world physics.

“Truthers” often insist that it is impossible to move more with less. Yet, things like levers, pulleys, etc. allow one to do exactly that. That tire jack that’s light enough for you to lift out of the trunk quite easily can lift up your car, no problem, something a person can’t do. I weigh considerably less then my car, yet I can push it, no problem. The fact that the car has wheels does not change the fact that it’s more massive than I am.

Now, since “truthers” are going to want me explain how the mass of the upper floors were able to move the much larger mass of the lower ones, it’s a little thing called force.

According to Newton’s 2nd Law of motion force is mass times acceleration, which is written as F = ma (source). Continue Reading »
