Creative Speculation

... which is why his schoolbus analogy broke my irony meter.

It isn't just the rather obvious structural differences between a schoolbus and the WTC towers, or the difference that scale makes, that make the analogy so absurd, although those are certainly relevant. The irony is that this guy is so completely clueless about the basic nature of the problem yet is pretending to understand physics. To a physicist, the question of whether an impacting object would destroy the impacted object is not answered by silly and invalid analogies. It's just a question of how much energy was involved in the impact and how much would be necessary to do the destruction. What if the VW was moving at 500 mph; would that be enough momentum and impact energy to destroy the schoolbus? A physicist would attempt to estimate the forces and resistances involved in a particular case to answer the question, whereas this guy doesn't seem to understand why that's necessary. And if he doesn't even understand that concept, then it isn't surprising that he doesn't understand Bazant's argument for why total collapse was unavoidable after it got started.

But the real irony of his "lesson" is that his "students" apparently don't understand it either.
