A heavy metal concert might be a tough place to think about physics.especially at the marsh pit while some audience members were dancing violently.But the marsh pit itself actually is interesting place to find physics and actions.and not just four sequence math times excelleration.Merdon,a quantum researcher,analyzed vedio of marsh pit ,and match the motions of participantces.they found that the collision of marshers were similar to motion of moleculars in ideal gas.marsher answered can also formed what is called a circle pit,but they run collectively in a rain creating a vore test parten. The scientists not only model marsh's circle pit ,they also found how one type of motiion transition into another. they present their ongoing working at the American Physical Society marsh meeting.but why bother to look at a marsh pit at the first place?
the physicst think their research may also apply other stream situatiions which could help us understand collective human movement in panics and riots.so I say rock on! |
