### Re: A very interesting Mathematical Paradox

I still can't get my head around how this works. The two examples i've been given are as follows. a) x = 0.9R 10x = 9.9R By subtraction 9X = 9 And so x = 1, and so 1 = 0.9R. (R for the old fashioned 'Recurring') But, if one were to multiply 0.9R by 10, the multiplied term would always have one less ...

### Re: Visual puzzle

Is it simply 'Black?' A black band comes after the blue band in the first one, where it says 'I come after blue' It comes before blue where it asks for it to come before blue. If we just ignore the 'discerning colour' of each band, black is the first band of the one where it asks for the 'first one'...

### Re: Three gods - True, False and Random

Spoilers ahead, for the curious! A helpful task in this is discerning, at the very least, a non-random god which we can ask two questions to find other gods, and therefore find the third by elimination. So, we need to find in one question a non-random god, though it doesn't matter which. In this...

### Re: Three gods - True, False and Random

Redrogue: How wonderful it would be if that worked, though I don't think it does. I'll try with an example. In this example, unknown to you, A is the Truth-teller, B is Random, C is False. Ja, stands for yes and Da stands for no. 1. (to A): If I ask B and C if I'm human, is B more likely to say 'Da'...
