Modern Sangaku

Sangaku are geometrical problems carved on wooden tablets. They were very popular in Japan during the Edo period (1603-1867).

Sangaku was the theme for the 12-30 project, month of November. I compiled the entire series with additional artworks inspired by the Sangaku tradition in one volume including over 60 illustrations, the original geometry they originated from, along with their mathematical description and possible solution

The book is now available in electronic format on the iBook store, GoogleBook, and Kindle. The individual images, large size print on canvas on SaatchiArt.
