Golden Section or Golden Mean Gauge

I have been reading the excellent book By Hand And Eye by Jim Tolpin and George R. Walker recently.
For those of you how might not have read this yet it "introduces us to the language of pre-industrial artisans" and "how period work is based upon how we relate to our own bodies and the world around us in terms of proportion, ratio and scale". It really is an interesting read and I encourage people to have a look at it.

I was speaking to a friend the other day and she mentioned the "Golden Ratio" and "Fibonacci Numbers"
I know from my time in engineering that when something "looks right" it invariably is right. It turns out that since ancient times people having been making use of the "Golden Ration" to design furniture, bridges, buildings so that they are pleasing to the eye.

Freely available books (Not just woodworking) on the internet

I was tasked by my wife Elly recently to find a copy of Ernest Hemingway's "Farewall to Arms". I saw the Kindle edition on Amazon for a few £s. I then thought as this is a classic it may be free somewhere else.

It is :)

I found the scanned 1929 version on archive.org it was freely available to download on PDF, kindle and many other formats.
Looking around on the site I searched for "woodwork" or "woodworking" and there is a mountain of books in there, both old and new, that are freely available for everyone to download and read. I'm currently reading "Elementary Woodworking" by Edwin Foster a 1903 tome. Everything in there is just as relevant in 2014 as it was in 1903.

Here is a link to the book

Have a look at the archive as it is superb.
