e is one of the well-recognized irrational numbers. It is famous for its transcendence. In this work, amongst the random-like digits in e after the decimal point, the occurrences of digit 0 in first 10 billion digits after the decimal point are analyzed for both successive and non-successiv...

indicator, the remaining 12 digits are based on the EAN-13 / UPC-12 article number followed by a check digit. tec-it.com 第一位数是包装 指示符,剩下的12位数是基于EAN-13 / UPC-12 货品号,接着是一个校验码。 tec-it.com The first digit in the course number denotes the category of th...
假如全部的10位自然数里有4.5%的质数,假设对于e的小数点后任意连续10位,都是一个统计意义上的随机数,那么前100位里出现质数的概率是1-(1-4.5%)^100,非常接近于1了,也就是说第一个质数出现位置的期望其实挺早的。 思路:原问题可以分成两个问题分别求解。

Finally, the first phalanx of digit IV is intermediate in size between the proximal phalanges of digits II and III. The tuberculum extensorius leans medially, and the lateral side of the corpus is straighter than the medial side. The cotylae articularis are deep and symmetrical. The second ...
一、如何算出或者找到足够精确的e? 1)e小数后100万位 计算公式: e计算公式 二、如何找到第一个10位素数 1)从第10位开始,计算前10为是否是质数。如果不是,则去掉第一位,增加最末一位,再判断,直到结果为真。 2)判断是否为素数:能被除了1和自身以外任意数字整除都不行 ...

digit length is “measured on the ventral surface from the basal crease to the tip of the digit”20. By adapting measurements from living people to archaeological skeletons, we proposed that the ratio of the length of the single phalanges of the fourth and second digits should differ as well...
