The authors invite reader to learn the main skills of the experimenter. The book provides general rules by which we experience the world. Case studies are selected from the various sciences, from physics and biology to criminology and sociology. Educational tasks and exercises are offered to the reader. How are subject and object of study born? Is there an algorithm for the process of the unknown cognition? What are the prerequisites of accidental discovery? How to improve the performance of experiments? Why are different scales to provide data used? The answers enable us to become the authors of our own discoveries. For undergraduates, graduate students, researchers.
