Interesting cmatrix find

I was scrolling through some internet science forums when I came across this:

http://www.physicsforums.com/archive.../t-379669.html

And I know it's from last year, but I thought it was pretty funny.
He couldn't find answers here (or just ignored them) so he jumped forums.They didn't put up with cmatrix's nonsense at all.

That's almost as painful as his YT videos.

I see he did his best to imply that near-freefall acceleration occurred at the beginning of the collapse rather than over a second after the first observed downward motion. And I see that, once the physicsforums members caught on, they showed him the door quickly enough. Nice to see my profession presenting itself in this light.

I'm not surprised, this is what kooks do. Trawl the internet making themselves look stupid trying to somehow fool people into believing in their paranoid CT delusions. I've even seen them pop up playing games on XBox Live.

Oh yeah... this was exactly the right thing to say in a physics forum to gain their sympathy.

I don't need to do any calculations. I understand how gravity, energy and momentum work in this respect.
Yet, he was making a quantitative claim:
Quote:
However isn't all the gravitational potential energy of the building used up in attaining free fall? Why did the structure in the way not slow the collapse in any way during this period? Fire can't blow out 8 stories of structure simultaneously and continuously floor by floor. Energy and momentum don't seem to be conserved here which is a violation of the laws of physics.
... and trying to defend it qualitatively. Good grief.

There's a gem in the bit you quoted which I missed on first reading:

"However isn't all the gravitational potential energy of the building used up in attaining free fall?"

...mmmm.

I liked that too. Thing like that make it easy to spot the truly clueless.

It is poor phrasing, but it's not wrong in and of itself.

Eventually, however, cmatrix responded to the challenge by doing the calculation...incorrectly: He multiplied 9.8 m/(s^2) by 2.25 s and interpreted the result as a distance in meters, not a velocity in meters per second.

For all his incessant yapping about physics, cmatrix couldn't even get his units right.

I was hoping his error would be identified later in that thread, and it was.
