A scientist is always led by intellectual curiosity; obviously he has collected information about the subjects of the field of interest in a systematic way (this attitude was moved by a peculiar interest that lets him investigate on all aspects of the problem, also dwelling upon aspects apparently marginal or non-traditional (this habit was not taught to him by anyone). In this case he already shows the so called "scheme-breaking" attitude rather than an attitude that would imply a systematic and essential examination of the state of art. This book addresses the scientific investigation carried out with the greatest originality driven by that intellectual curiosity but it must face the experimental evidence to get irrefutable results.
