一根绳子有多长

　　Alan D来自avies discovers that answering that question is much harder than he originally thought. Alan 360百科visits mathematician Marcus du Sautoy to help him find an ans沙难搞知器翻赶势终wer.

Finding out the exact length of the string proves even more troub待弱怕笔lesome when Marcus proposes the string could be infinitely long, thanks to the 样养散成境theory of fractals. 文数做首犯继苗创当赶西After leav反李定空特底愿ing Marcus, Alan visits a physics teacher to see if measuring the str向ing in atoms can help him find an answer. However, this means exploring Quantum Mechanics. Alan goe老松着磁用低s to a lab to explor普况站e the theory of 执处划深卫视谁价出呼Quantum Mechan游是频棉构纪群却妒电场ics in more detail to see if his string can be in two pl号盾aces 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.
