项目名称:Cuboids
官方网站:http://www.physics.ox.ac.uk/cm/cmt/cuboid/
项目主旨: Help the Cuboids project determine the probability with which various cuboids (six-sided dice with parallel faces but non-equal edge lengths) will land on each of their surfaces. This simple problem is a 'truncated chaotic' phenomenon, and doesn't fit neatly into ordinary areas of physics. The results of this project will have "several important practical applications, from manufacturing (i.e. objects falling on conveyer belts) through to packing of granular material and proteins."
The project will simulate one billion cuboid tosses, in an effort to answer the following questions:
How do probabilities scale with edge ratios?
How do probabilities depend on elasticity and friction?
How do final states depend on initial conditions?
主持机构:University of Oxford
既然是牛津大学主持的,就不太好说是娱乐性的了。
Beautiful questions are simple to ask yet hard to answer:
You roll a six-sided die with parallel faces but non-equal edge lengths. What is the probability to land on each surface ?
最美妙的问题是那些看起来极其简单却让人难以做答的问题:你扔出去一个色子,六个面在“人权”上是同等地位的,可为什么老天却总要眷顾某个面,而让她有更多的机会面朝蓝天高高在上? |
