[BBC系列]：一段绳子有多长How Long is a Piece of String-1080P高清迅雷网盘下载
------------------------------------------------------
由艾伦·戴维斯（Alan Davies）和马库斯·杜·萨图（Marcus du Sautoy）共同主办，由英国广播公司（BBC）发行的科学，技术纪录片，作为2009年英国广播公司地平线系列的一部分播出-Science, Technology Documentary hosted by Alan Davies with Marcus du Sautoy and published by BBC broadcasted as part of BBC Horizon series in 2009- English narration
------------------------------------------------------
一段绳子有多长？艾伦·戴维斯（Alan Davies）发现，回答这个问题比他最初想的要难得多。艾伦（Alan）拜访了数学家Marcus du Sautoy，以帮助他找到答案。但是，这带来了更多的问题，需要前往专门用于测量的地方，即国家物理实验室。由于分形理论，当马库斯（Marcus）提出弦可能无限长时，找出弦的确切长度变得更加麻烦。离开马库斯（Marcus）之后，艾伦（Alan）拜访了一位物理老师，看看测量原子中的弦是否可以帮助他找到答案。但是，这意味着探索量子力学。艾伦（Alan）去实验室更详细地探索量子力学的理论，以查看他的弦是否可以同时出现在两个位置，从而使他更加困惑。仍未接近答案。艾伦被介绍给他的弦可能同时具有多个长度的理论，所有这些都是在毛绒猫的帮助下完成的。艾伦不相信量子力学在基本规模上很重要，但是光合作用和嗅觉能力可能只会改变他的想法。如果艾伦（Alan）找到最准确的方式来测量他的琴弦，那么从理论上讲他可以制造一个黑洞。试图找到解决这个问题的方法对艾伦来说是一次哲学之旅，但他仍然拜访了萨斯·马库斯（Marcus du Sautoy）来告诉他自己的答案。如果艾伦（Alan）找到最准确的方式来测量他的琴弦，那么从理论上讲他可以制造一个黑洞。试图找到解决这个问题的方法对艾伦来说是一次哲学之旅，但他仍然拜访了萨斯·马库斯（Marcus du Sautoy）来告诉他自己的答案。如果艾伦（Alan）找到最准确的方式来测量他的琴弦，那么从理论上讲他可以制造一个黑洞。试图找到解决这个问题的方法对艾伦来说是一次哲学之旅，但他仍然拜访了萨斯·马库斯（Marcus du Sautoy）来告诉他他的个人答案。How long is a Piece of String? Alan Davies discovers that answering that question is much harder than he originally thought. Alan visits mathematician Marcus du Sautoy to help him find an answer. However, this creates more questions, which requires a trip to a place dedicated to measurement, the National Physics Laboratory. Findingout the exact length of the string proves even more troublesome when Marcus proposes the string could be infinitely long, thanks to the theory of fractals. After leaving Marcus, Alan visits a physics teacher to see if measuring the string in atoms can help him find an answer. However, this means exploring Quantum Mechanics. Alan goes to a lab to explore the theory of Quantum Mechanics in more detail to see if his string can be in two places at once, confusing him even further. Still no closer to an answer Alan is introduced to the theory that his string may have multiples lengths at the same time, all with the help of a stuffed cat. Alan doesn’t believe Quantum Mechanics is important on a basic scale, but photosynthesis and the ability to smell might just change his mind. If Alan was to find the most accurate way of measuring his string he could theoretically create a black hole. Trying to find the solution to this question has been a philosophical journey for Alan, but he still visits Marcus du Sautoy to tell him his personal answer.
