Pythagoras was more a mathematician than philosopher AFAIK and Phi was just a bit of algebra, meat and drink to him I would have thought.

I agree though it's all a mystery.
well, pi isn't really 22/7, but I take your point.

nice link gareth, still does not answer my favourite question which is
since pythagorus was greek and his empire was stuffed by the romans,
who did not have a zero in their numbers how did the number get where it is??? :? :twisted:
you imagine trying to do the sums in latin numerals????? :twisted:
the other wonder is with all the stuff lost during those wars, how much
knowledge did we lose that could explain these numbers. :roll:
anyway, re the marking gauge again. notice steve maskery's article in the latest GWW about a marking gauge, and not to demean what he has written, this is an ideal situation for the tatty old engineers scribing stand,
and either an analogue or digital dial gauge on the pillar. if bugbear is right they are extremely cheap at boot sales, so might be worth the effort.

nice one jacob, the only thing i disagree with is that latest research suggests that the number zero was sanskrit, and comes from the indian sub continent. stones have been found and dated before babylon as
i understand it from a recent tv series about maths.

actually those old engineering and maths books are really fascinating.
