PTE听力口语练习-科学60秒- Mosh Pits

PTE考生目前最大的问题之一就是练习题缺乏。除了有限的基本官方书(PLUS,Testbuilder, OG)之外,就没有题了。很多英语基础不是很扎实的同学很难找到练习材料。墨尔本文波雅思PTE培训学校专门为墨尔本,悉尼PTE考生准备了适合PTE听力阅读练习的科学60秒。各位PTE同学可以练习PTE听力中的summarise spoken text和PTE口语中的retell lecture,PTE听力口语-科学60秒-Frosty Moss练习记笔记技巧和复述。废话少说,下面开始:

Physicists Model Mosh Moves


60秒科学节目(SSS)是科学美国人网站的一套广播栏目,英文名称:Scientific American – 60 Second Science,节目内容以科学报道为主,节目仅一分钟的时间,主要对当今的科学技术新发展作以简明、通俗的介绍,对于科学的发展如何影响人们的生活环境、健康状况及科学技术,提供了大量简明易懂的阐释。

Metal-loving researchers analyzed the collective movement of individuals in mosh pits, which could help explain mass movements in other extreme situations. Sophie Bushwick reports


A heavy metal concert might be a tough place to think about physics, especially in the mosh pit, where some audience members dance violently. But the mosh pit itself is actually an interesting place to find physics in action. And not just force equals mass times acceleration.

Metal-loving Cornell researchers analyzed videos of mosh pits and mapped the motion of participants. They found that the collisions of moshers was similar to the motion of molecules in an ideal gas. Mosh dancers can also form what is called a circle pit, where they run collectively in a ring, creating a vortex pattern.

The scientists not only modeled mosh and circle pits, they also found how one type of motion transitions into the other. The presented their ongoing work at the American Physical Society’s March Meeting. [Matthew Bierbaum et al., Mosh pits and Circle pits: Collective motion at heavy metal concerts]

But why bother to look at mosh pits in the first place? The physicists think their research may also apply to other extreme situations, which could help us understand collective human movement in panics and riots. So I say, rock on.
