If you have ever completed a technical apprenticeship (Ausbildung) in Germany鈥攁s a Mechatroniker, Elektroniker, Anlagenmechaniker, or Fachinformatiker鈥攜ou know the sacred text. It is not a novel. It is not a thriller. It is the Tabellenbuch .
Thick, dense, and wrapped in a sturdy, often orange or blue cover, this book is the bible of the workshop. It contains everything: material properties, electrical formulas, geometric tolerances, safety regulations, and even the occasional outdated DIN norm from 1972 that no one has ever used.
The publishers鈥擡uropa, Westermann, Verlag Europa-Lehrmittel鈥攌now this. They update the books every two years to include the latest VDE regulations or ISO standards. They claim it鈥檚 for safety. The apprentice claims it鈥檚 a racket.
But is it immoral? Ask any Meister or Ingenieur. Most of them will lean over, lower their voice, and say: 鈥淛a, ich hab auch eins. Aber sag鈥檚 nicht weiter.鈥�
