Science is when someone scientifically creates new knowledge! Therefore, this textbook and reference book is not only about techniques, but about a consistently investigative attitude and approach. Those who follow the approach of this book will no longer want to „write about“ something, but rather to investigate something – with the passion of a researcher. This compilation of the basics of scientific research is a textbook of the Veganomics Institute. Also the veganism needs for all its facets – ethics, health, ecology, economics etc. – always the respective scientific bases and research results and should constantly in it cooperate. The principles of science and research naturally also apply to other problems and solution goals. Therefore, this book has been designed to be useful to everyone. At the same time it serves as an accompanying book to the online course of the same name at forschenlernen.jetzt – it summarizes all the video lessons, contains the task sheets and thus helps with more in-depth self-study.
