I really can't imagine that number being the root of any rational number. Also, I can't imagine it is a number of any mathematical significance, since what number you get depends on what base you're in. What brought you to this question? –  Arthur Sep 16 '12 at 12:11
@Arthur: You mean "a root of any rational polynomial", right? As for mathematical significance, it is not obviously less worthy of consideration than the Champernowne constant or Liouville's number. –  Henning Makholm Sep 16 '12 at 12:13
@Clive: That's an answer! –  Henning Makholm Sep 16 '12 at 12:17
@HenningMakholm: If you say so ;) –  Clive Newstead Sep 16 '12 at 12:19
Classify mathematical objects in "significant" and "not significant" is a good way to limit yourself in mathematics. If everyone since the beginning of history would merely make significant math, we would never be at this level of mathematics we have today. –  Integral Sep 16 '12 at 15:37
