Do We See the ``Dark Clouds'' Again? --- On Some Puzzles in Contemporary Physics
Abstract
Some conceptual problems in physics are discussed. Do we need a change in the concept of matter structure? Why the ``i=-1'' is introduced to quantum mechanics (QM) essentially? What is the relation between QM and special relativity (SR)? Could we modify the stationary Schr odinger equation in conformity with SR? How can a particle acquire a mass? We propose some tentative answer. Their philosophical implications are emphasized.
