This book not only presents innovative methods for learning Einstein's special relativity from a different aspect (Vol. I) but also reveals deficiencies and paradoxes of this theory in a plain-language style (Vol. II). Since the advent of special relativity theory (SRT), it has become so accustomed to applying the Lorentz transformation straightforwardly in order to solve the relativistic problems abstractly. However, such a mechanical method cannot provide the student with a profound and visualized intuition about what exactly happens to the physical phenomena in the framework of SRT. This tendency has stirred up ambiguities on whether the theory is really exonerated from the accusation of including anomalies or being paradoxical.
