ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book describes the ‘red thread’, is of interest by virtue of the detailed examples which one encounters in seeking ultimates, but often finds incompleteness and imperfection. Of course everybody who is engaged in creative work looks for imperfections with a view to improving his or her creation. The imperfections seem to come in three types: intrinsic imperfections, limit-imperfections of theory, and imperfections due to lack of knowledge. The notion of position and velocity as applied to a particle becomes fuzzy in quantum theory, when applied to one particle at one instant. If physicists look hard enough, they will often find that something is missing. This phenomenon reveals itself in rather diverse and sometimes surprising ways. The mathematical sophistication and complication in some of the arguments of physics can lead to exaggerated claims.
