Unificationist Approach and Standard Quantum Mechanics

This paper aims toward the formulation of unificationist approach in the development process of standard quantum mechanics (SQM) during the years 1913-1927، focusing on Bohr and Heisenberg as the two prominent founder scientists of ‘Copenhagen’ quantum mechanics. In this investigation، we formulate various types of unificationist approaches involving reductionist، analogist، and holistic forms of unificationism، within Bohr’s and Heisenberg’s main works. Thus، one part of this paper is devoted to description and articulation of several kinds of unificationism from philosophical point of view. Another part is devoted to the conceptual and philosophical analysis of main works of Bohr (including atomic model، correspondence principle، and complementarily) and Heisenberg (Matrix mechanics and indeterminacy relations). This analysis includes origins، methods، contents، and consequences of their works on physics، in the specific period of SQM development.
