Would you like to be an astronaut? Well, it may not be an idea too far-fetched in the near future, depending on where the boundary of space is. :) Article Link

Consider a mathematical series, f^n (10) = 10^n + 10^(n-1) + ... ... +10^2 + 10^1 + 10^0. It looks terrible and confusing, but what that basically means is that every number we know is a combination of the powers of ten (thousands, hundreds, tens and ones being the first four among the natural numbers series). Take 45,231 for example. That's [4 x 10^4] + [5 x 10^3] + [2 x 10^2] + [3 x 10^1] + [1 x 10^0]. Think of it as Primary School Mathematics written in a bizarre way. 40
