"Satz explores how an agglomeration of constituents forming a system can demonstrate discordant behavior that does not correspond to expectations. The text features helpful graphic illustrations of important concepts. The exposition is elegant and clear." -- N. Sadanand, CHOICE "Is the whole always equal to the sum of its parts? This slender book by Satz addresses this question with examples from different areas of science." -- N. Sadanand, Central Connecticut State University "The book is oriented to engage a diverse readership interested in new perspectives in physics, presenting an entertaining narrative that explores the enthralling concepts surrounding the field of complexity, concepts that have become integral in shaping our comprehension of the physical world. Particularly, undergraduate, and graduate physics students will benefit from reading it, as it provides a gateway to understanding how complexity principles apply to a multitude of physics problems, effectively opening a new realm of discovery.
