Paul Klee was endowed with a rich and many-sided personality that was continually spilling over into forms of expression other than his painting and that made him one of the most extraordinary phenomena of modern European art. These abilities have left their record in the four intimate Diaries in which he faithfully recorded the events of his inner and outer life from his nineteenth to his fortieth year. Here, together with recollections of his childhood in Bern, his relations with his family and such friends as Kandinsky, Marc, Macke, and many others, his observations on nature and people, his trips to Italy and Tunisia, and his military service, the reader will find Klee's crucial experience with literature and music, as well as many of his essential ideas about his own artistic technique and the creative process.

'One of the most famous of modern art documents - a poetic primer, prepared by the artist for his Bauhaus pupils, which has deeply affected modern thinking about art . . . This little handbook leads us into the mysterious world where science and imagination fuse.' Observer

Eco-Mathematics Education strives to show how everyone can experience the embedded connection between mathematics and the natural world. The authors’ sincere hope is that by doing so, we can radically change the way we come to understand mathematics, as well as humanity’s place in the ecosystem. The book hopes to accomplish this by providing in-depth lesson plans and resources for educators and anyone interested in teaching and learning mathematics through an ecological aesthetic perspective. All lessons are based on the inquiry method of teaching, aligned to standards, incorporate art projects inspired by famous artists, and utilize recycled and/or natural materials as much as possible.
