Collapse
Saw a computer simulation of the collapse on PBS last night.
The towers came down differently, with the immediate cause different for each one.
Fascinating. Absolutely fascinating. Taped it, and have watched it again.
I'd recommend it to anyone who isn't resistant to learning from a computer simulation.
Folks with 19th Century political views won't like it. Computer "simulation", and all that. Not good. Never be worth anything.
But for folks with 21st Century educations, a capacity to visualize, and an ability to apply abstract ideas to drawings, it's just intriguing.
