Version 1.2

I have just published version 1.2 of the book. Since there is no English version of it yet, it makes little sense to talk about the changes. I’ll just say that I put a lot of work into making the book more accessible than it was before, which should make the English translation alot better as well.

After the extensive changes in this version, there will certainly be at least one more exclusively German version 1.3 with fine-tuning. But this text version should already be a good basis for the English translation. :-)
