This book is based on the German textbook published in 2008 and the English textbook published in 2010. I would therefore like to thank all the people who contributed to these two books. You will find the acknowledgements for the previous editions here:

Acknowledgement English textbook (2010)

Patricia Aluko Obe, Philipp Bohn, Jennifer Brings, Johanna Buchner, Nils Linus Feldt, Felix Föcker, Heike Göris, Semir Ikic, Kevin Keller, Lisa Krajinski, Andreas Metzger, Alexandra Pompalla, Andrea Salmon, Phillip Schmidt, Viktoria Stenkova, Bastian Tenbergen, Theresa Wettig, and Thorsten Weyer. 

Many thanks to them all! 

In particular, I would like to thank four people who have significantly supported me in the preparation of the new edition through their contributions and their perseverance:  

Torsten Bandyszak, Katharina Böse, Birgit Kremer, and Marian Daun

Guys you did a great job! 

Furthermore, I would like to thank our students, industrial partners, and the people attending our tutorials and trainings for continuously asking critical questions - a valuable source for many improvements. I also want to thank Heike Göris for her support with proofreading, as well as Ralf Gerstner and Phil Watson from Springer for their support in publishing this edition of the book. 

I would especially like to thank my wife Iris for her patience and understanding for the many evenings, weekends, and vacation days I invested in writing this book!
