The article linked is "quaint," but uninformative.
the commonly accepted premise that since 9/11, all steel buildings that suffer limited fire damage implode within two hours.
"commonly accepted" ????? by whom? [derogatory quesses as to identity and qualifications deliberately suppressed].
I suppose it's "commonly accepted" that any common wood framed home that suffers limited fire damage may "explode" withing 30 minutes as well, but I had a recent fire in my home that scorched the bean soup severely and produced "noticeable" smoke and odor. While the "fire" was confined to the stove burner where it was more or less expected, it was only by some miracle defying the laws of physics" I, and my family, and my home, survived.
I think I deserve equal time in the media.
Damage was severe. I had to clean the pot and open another can.
(If the thread originator is in fact a "Physics Major" it might be suggested that out of respect for those who deserve the title his/her usage might be withheld pending the second year of high school.?)
