费曼点 Six nines in pi

（重定向自Feynman Point）
图为π的数值至小数点后数百位，当中含有大量双重连续的数字（黄色标记），和几组三重连续数字（绿色标记）。还有一组六重连续数字（红色标记），叫“费曼点”，能在这么小的样本中出现这样一个点，可说是一个很有趣的破格。
The first 1000 digits of π contain ample double consecutive digits (marked yellow), and a few triples (marked green). The presence of the sextuple (marked red) in such a small sample is an intriguing anomaly. For comparison, τ (2π) contains a run of 7 nines (marked purple) near the same point.

在圆周率的小数值中，费曼点是从小数点后第762位开始的连续六个9。它是以物理学家理乍得·费曼来命名，因为他曾经在一次讲课时说过，他希望能把π记到那一个点，那么背诵到最后时，他就可以说“九九九九九九等等”，也就可以半开玩笑地指出，π其实是一个有理数。

A sequence of six 9s occurs in the decimal representation of π, starting at the 762nd decimal place. It has become famous because of the idea that one could memorize the digits of π up to that point, recite them and end with "nine nine nine nine nine nine and so on", which seems to suggest that π is rational. The earliest known mention of this idea occurs in Douglas Hofstadter's 1985 book Metamagical Themas, where Hofstadter states
