Essentials of Quantum Mechanics and Relativity

Guang-jiong Ni

Why does the $i=\sqrt{-1}$ appear essentially in the quantum mechanics? Why are there operators and noncommutativity (the uncertainty relation) in the quantum mechanics? Why are these two aspects closely related and indivisible? In probing these problems, a new point of view is proposed tentatively.

Some conceptual problems in physics are discussed. Do we need a change in the concept of matter structure? Why the ``$i=\sqrt{-1}$'' is introduced to quantum mechanics (QM) essentially? What is the relation between QM and special relativity (SR)? Could we modify the stationary Schr$\ddot{\rm o}$dinger equation in conformity with SR? How can a particle acquire a mass? We propose some tentative answer. Their philosophical implications are emphasized.

If the idea that science cannot access hypothetical absolute determinations of what is but only relations is not a novel one, this article shows that we owe quantum mechanics for having systematized the relational character of scientific knowledge. This article clarifies the types of relation that come into play and the reasons why they have been ignored by classical physics prior to quantum physics and calls for a discussion on the full philosophical implications of relation.
