Russian dolls, the wooden doll with the series of miniature versions of itself inside it...Is actually a Japanese invention. That is, they did it for ages, and then recently the Russians copied them. Now they are all 'Russian Dolls' and people think the Japanese are rip-off artists. All lies!Also; This is a fact:1/3 = 0.333...3 * 1/3 = 3 * 0.333...1 = 0.999...But you may be experiencing difficulty in believing it.
