All suggested notions of reduction of two scientific theories are critically reviewed and analyzed. In particular those applied to the case of the alleged reduction of Chemistry to Quantum mechanics are examined. Since it is recognized that the weakness of this field of research is the lack of a definition of a scientific theory, it is suggested that a scientific theory is characterized by two choices regarding two dichotomies, that is, the kind of mathematics and the kind of logic. According to this view a reduction is only possible between two theories in which the same choices are shared. As a consequence, only one case of reduction in the history of physics is recognized: physical optics to electromagnetism, a case that is commonly accepted. The other cases of claimed reductions are recognized as impossible, owing to the different choices of the two theories at issue and hence the radical variations in meaning of their shared basic notions. In particular, the claimed reduction of Chemistry to Quantum mechanics is disproved in detail.

两种科学理论之间的还原的新定义：没有将化学还原为量子力学

所有关于还原两种科学理论的建议概念都经过严格审查和分析。特别是那些适用于所谓的化学到量子力学的简化案例的研究。由于认识到这一研究领域的弱点是缺乏对科学理论的定义，因此提出科学理论的特点是关于两种二分法的两种选择，即数学的种类和数学的种类。逻辑。根据这种观点，只有在共享相同选择的两种理论之间才有可能减少。因此，物理学史上只有一个还原的案例被承认：物理光学到电磁学，这是一个普遍接受的案例。其他要求减少的情况被认为是不可能的，由于所讨论的两种理论的选择不同，因此它们共同的基本概念的含义存在根本差异。特别是，声称的化学到量子力学的简化被详细地反驳了。
