      Bring research out of the ivory tower! That could have been the motto of bio mechanist Mattheck when he wrote this cartoon-like little textbook on body language and interacting with trees. Old-style scientific publications usually only come to the attention of the general public after many intermediate stages – if at all. Here, a successful attempt has been made to convey new scientific findings directly and in an entertaining way to a wide readership.

      Many people would never buy a book about biomechanics, which is understandable, because it sounds like complicated science. With his charming little book, Claus Mattheck breaks down the barrier of dry science. With unparalleled openness, physicist and illustrator Mattheck sends his hedgehog Stupsi up into the trees. They tell him the secrets of tree stability in the simplest form. The cheerful illustrations at the beginning of a lecture on tree biology encourage many students to tackle complicated subjects.

      This booklet makes it easy for anyone who wants to understand the body language of trees. The author refrains from providing evidence in favour of simplicity. Scientifically rigorous treatises can be found in his other books. The author's beautiful drawings appeal to both the mind and the heart in equal measure and will forge new bonds between trees and people on the one hand and tree lovers among themselves on the other.
