Powers of 9 pdf.

Download the full text version of ‘Powers of 9’.

This book is available as a free pdf download, or can be bought through Bookvault, a print on demand company based in the UK. This book has only been edited and proof read by myself, and since it is printed ‘on demand’, I can change the file at anytime to improve the text.
So, if you have any input, if you spot a spelling or grammar error, you can always let me know, then I can change the master file and the next purchaser will get the corrected version. Collective proof reading/editing.
All inputs will be appreciated!
