Pooh, I only know it as 3.14159265358979... Perhaps I refer to my phone number as a substring of the decimal expansion of pi. Ah, yes, there it is, starting at the 14569419th digit after the decimal point. (14159... starts at the 1st digit after the decimal point.)
Perhaps Murgatroyd's phone number is something like 314-1593 or 278-1828.
Here's a "simple" question: is every possible string of digits equally likely to occur in the decimal expansion of pi as it would be in a randomly generated sequence of numbers?
Another "simple" question: is it possible for pi in some exotic geometry to be less, or more than 3.14...?

There are some 700 - 800 million native speakers of Mandarin (depending on survey), and some 1,080 million native speakers of any sort of Chinese. There are 1.3 billion ethnic Chinese, though I will grant that a good portion, if not most of the overseas Chinese population (about 34 million) do not speak any sort of Chinese as their first language, and some of them don't even speak any sort of Chinese.
The sum of the populations of the US, UK, Australia and Canada is only about 410 million. Other countries, which have English as one of their official languages (interestingly, USA does not), do not necessarily have English native speakers as 100% population, or even more than 50%...
