I studied quite a lot of botany as part of my arboricultural education and from a quick read of the enclosed Phi I feel it is a ridiculously simplified theory , plants have so much variety , the example given might apply to bamboo perhaps , but what about contorted hazel for example ? far too much to go in to detail here but I was wondering whilst looking at almost any tree what do I multiply by 1.68 ?? ... Terry Sevilla... I usually listen to Planet Rock when in my shed !!!
Yes Terry it was a simplified example but I thought it a good place to start taking into account you initially said you had no idea how x 1.68 refers to nature. Many of your questions can be answered from the previous book I linked, I also had to study a lot about plants in my last job

and you will find the cannabis leaf as all are fine example indeed of Phi.

although I did not realise it at the time.

The relevance for me is that it is a very useful tool for people in relation to further development in design. Of course we do not have to take any notice of it but I believe you can see the makers who have studied it as their work stands out.
In relation to a contorted hazel, the twist, rise of twist and point at which new shoots develop are in direct correlation to Phi, this link
this link, again it is very simple explanation but then Phi is very simple, at times however as for me initially, it appears overly complicated as with any subject, but with a short time of study it opens many more avenues to us than the relatively short time of frustration of learning, I guess it depends if you want to put the work in to study or not.
People will be thinking I am sure,!!

what has this Phi fallooting stuff
![Smiley :)](http://www.awgb.co.uk/awgbforum/Smileys/classic/smiley.gif)
got to do with wood turning beyond the proportions of a foot, box or height. ?
The spirals on a stair spindle or those around a hollow form are examples as are the position of curve for the perfect ogee curve, again research of the ogee shows a direct relation.
I appreciate all this talk of a maths ratio may seem a load of tosh
![Smiley :)](http://www.awgb.co.uk/awgbforum/Smileys/classic/smiley.gif)
but good design comes from an understanding of design itself, an understanding of design comes from the understanding of geometry and relationships and this means Phi, if not then why do graphic designers and architects have it included in their formal education ?, wouldn't be much good for an architect to say to a client ' well every now and then a building I make looks real good but at other times not but I don't know why' !! How can we as makers hope to develop what we do if we have little or no understand of the basics of proportion ?
The books and other links are useful for those that would like to delve into it further, if not no worries.
Little more for me to add as I am a convert, so if you are interested get and study the book, if not don't

, simples as 1.618
