 Jan 3 awarded Nice Answer Dec 8 awarded Caucus Dec 7 comment Can I get a decimal number does not contain a similar consecutive double-digit??? Try $12/99 = 0.12121212...$ Dec 1 awarded Nice Answer Nov 29 comment Prime numbers stretch to infinity, but what about the distance between them? But Zhang's result does prove the "probably" at the top: it proves that $\liminf_{n \to \infty} (p_{n+1} - p_n)$ is finite, and therefore the $\limsup$ and $\liminf$ are different, i.e. the limit definitely does not exist. Oct 2 awarded Enlightened Oct 2 awarded Nice Answer Sep 30 awarded Explainer Sep 24 awarded Autobiographer Sep 23 comment Does the number pi have any significance besides being the ratio of a circle's diameter to its circumference? @Ant: My comment was a reply to asmeurer's speculation that it had to do with "angles and the 2D lattice" -- my comment was not a reply to anything in this (damiano's) answer. Sep 22 comment The myth of no prime formula? You ignored the word "useful" in Tao's comment: here, "useful" means something that allows us to compute the $n$th prime significantly faster than what follows straightforwardly from its definintion. Sep 22 comment Why doesn't the definition of the interior of a set depend on the dimension of the set The definition of interior does depend on the space you're working in (in exactly the ways you mentioned). What definition have you seen? Sep 21 comment Is there a known mathematical equation to find the nth prime? Why the downvote? Sep 20 awarded Revival Sep 20 comment Look at the following infinite sequence: 1, 10, 100, 1000, 10000, . . .. @Olcayto‌: Any number and any sequence. :-) Sep 17 awarded Good Answer Aug 16 comment Is '10' a magical number or I am missing something? @JoSo: You may notice that I always used "base 1" in quotes — of course it's not one of the general class of "base n" representations, but there does exist such a thing as the unary numeral system: en.wikipedia.org/wiki/Unary_numeral_system. I feel I'm repeating the comment I made to user dhasanen above. In the unary numeral system, you can use any symbol you like (either 0 or 1 or X or whatever), and correspondingly 0000 or 1111 or XXXX would represent the number 4.
