I thought that article was pretty good. Not because I think the equation can be precise, but because the methodology of the assumptions seems sound.
Oh, I'm sure the the math is fine. However, the more inputs into an equation, the more variable the output. Let's try this with something similar.
If I studied the price movements of the stock price of 3 companies, and then compared them with the stock prices of 4 other companies, and then told you the 4 companies had to be fictitious, because they didn't match the first 3; how certain would you be that i was right? The math could be right, and still I wouldn't be.
What if we set the bar lower, and I just told you a price range for those 4 companies? Again, my math can be right, and I am totally wrong.
What if we set it even lower, and I just tell you what the price of one stock would be? Again, my math can be right, and I'm wrong.
Is this because math doesn't work? Of course not. It is because math is a tool, used properly, it will help you get done what you need to get done.
I'm sure if the mathematician who worked up the formula had a chance to explain it, he would have pointed out the caveats. Instead we had a journalist, and journalists use doubt as part of the story, only when the story is about doubt. For people familiar with using math to calculate a hypotenuse, math seems a tool of great precision and accuracy.
But people who use math to model reality have an entirely different view of math. It set ranges and boundaries of uncertainty.
Using math to calculate that shearing this column, in this old building, which has been modified in these ways, in this place, with fires on these floors that gave been burning this long, and...
The uncertainty exceeds the solution set. Even an engineering student wouldn't make the mistake of thinking he could calculate where and how to get a collapse in those circumstances.
And all this aside from anyone coming up with a motive for anyone to want to do such a thing, or time it as they did.
This is just reality as it is understood by people educated by Hollywood. Disney would have told a more realistic tale, as an animated musical.
