We could subtitle "Discovering possible." I love this book and reread a few pages occasionally. It is clear, easy to experiment, everyone remains satisfactory and scientifically. The books of Barbel Morh, on the same subject, but if I compare it to that of Vadim Zeland, I will say that Barbel Morh teaches kindergarten and Vadim Zeland, in high school. Personally, I like to know the why of things and I found it in part on this one. I recommend it to all open minds. I doubt that materialists madmen like it. I have not read the previous volumes. One is complete in itself.
