String, Straight-edge and Shadow

‘Shows us what we don’t realise we know, what civilisations before us learnt and passed down to us. It brings an awe and magic back to our learning… Those that advanced knowledge of geometry had a grounded and practical understanding of where it came from. This book helps us to do that.’– The Smart Happy Project‘This was an enjoyable read for the everyday person of curious mind.’ - Amazon.com‘Fantastic, accurate, readable, teachable and Classical.’ – Amazon.com‘The well constructed narrative brings these people and their excitement over these discoveries to life. I learned about the patterns in math from a new perspective and it made me wonder why math is always taught in the abstract format. These people understood it in a completely different way and I would think that some people would learn it better if it were explained this way.’ – Goodreads‘This gem is about ancient Geometry that has definite application today. Knowing the stories behind many great discoveries make them so much more interesting and really helps math to come alive.’ – Goodreads‘Whether you are learning geometry for the first time, teaching it to students at home or in the classroom, or are parents helping your children through their first geometry course, this is a must-read for everyone! You will be fascinated with the graphic illustrations and written depiction of how the knowledge and wisdom of so many cultures helped shape our civilization today.’ – Waldorf Books‘String, Straight-edge and Shadow (is) an interesting and informative book and its numerous diagrams and illustrations are part of its appeal. Anyone interested in learning how discoveries made thousands of years ago still underpin much of our modern day science and mathematics will find this a useful and engaging read.’– New View

Julia E. Diggins (1903–1987) studied mathematics and psychology in Washington, DC. While teaching mathematics in junior high school, she was awarded grants by the National Science Foundation and worked with members of the Maryland University Mathematics Project on the preparation of a new curriculum. She taught ‘modern’ mathematics for elementary school teachers at the University of Maryland, USA.
