(The Atlantic)   Grad student goes to a metal show and accidently discovers some physics. "It turns out that the statistical description we use for gasses matches the behavior of people in mosh pits. In other words, people bounce around like the molecules in a gas"   (theatlantic.com) divider line 17

I had no idea gas molecules could cease brownian motion if they got 'accidentally' kneed in the gonads.

Skyrmion: It wouldn't be your typical "ideal gas". Collisions are inelastic, and the molecule - molecule distance isn't large compared to the "molecule" diameter.


They're essentially elastic, as people continue moving at about the same speeds after colliding due to personal preference.

2d instead of 3d changes the shape of the curve a lot, though.

prjindigo: this kind of shiat is why 60% of the world believes in the greenhouse effect even though its own creator disproved it more than two decades ago...


Don't be ridiculous; no one created the world.

WhippingBoy: Well, that confirms it: Grad students are officially the most useless people on this planet.


YEAH! When did mathematical analysis of random stuff in our environment ever do anything useful?!! BOO MATH!

When I'm a physics teacher, this is what my exams will look like:

"Dave Brockie squirts fake semen into the crowd at an angle of 38 degrees with a muzzle velocity that varies from 0 to 3 m/s. How many rows back would you have to sit to be in the clear if the stage is six feet high, and the angle of elevation of the floor is 10 degrees?"

"Jello Biafra, a dilectric, stands in a puddle of water during a Kennedys show and gets too close to the mic.  If the area of the mic head and water are each .001 m, the distance from his mouth to his feet is 1.5 m, and his presence causes a potential drop from 3 x 104V to 1x104V, calculate Jello's permittivity."

poorjon: brantgoose: I have a theory that the way that people pack themselves...

Your theory fails explain effects observed in the presence of back packs, bicycles, or carts. Does it assume these articles are represented by perfect circles, or ellipsoids? Furthermore, I prefer to lean against the wall when alone in an elevator, rather than stand in the exact center. I deny your grant application due to unsupportable hypotheses in your initial plan of investigation and an abject failure to cite the ever loving crap out of my personal body of work.


First, we assume a spherical human...

So... you're saying that the original model used for describing random motion of molecules -- the very same model that is literally based on a drunkard's walk -- also describes drunk people thrashing around at a concert?

Brilliant.

As well, there seems to be preferential attraction near hot chicks.

Grad student makes an analogy out of a mosh pit that kind of works for gaseous molecules. This doesn't mean anything to science.

The molecules in a liquid have taken the brown acid and are just wandering around, being loose and weird, man.
