摘要

要理解模型在科学中角色的独特之处,就需要描述这些模型在面对实验结果时如何演变的广泛模式。也就是说,我们不仅要研究静态模型——模型在某个时间点如何与理论联系,或如何代表世界——还要研究动态模型——模型如何产生新的实验结果,并根据这些结果进行修改。结构的视觉表征在有机化学家的理论推理中起着核心作用。毫不奇怪,在整个有机化学的历史中,这些表征随着实验和理论的发展而发生了重要的变化。在许多情况下,理解有机化学家作为模型使用的视觉表示是合适的。因此,有机化学家的结构表征的演变为科学建模的动力学提供了一个清晰的例子。在这篇论文中,我使用了从Mary Hesse的工作中提取的科学建模的概念来研究如何将分子构象的概念纳入有机化学家使用的结构的视觉表示中。

Visual Representations of Structure and the Dynamics of Scientific Modeling
Understanding what is distinctive about the role of models in science requires characterizing broad patterns in how these models evolve in the face of experimental results. That is, we must examine not just model statics—how the model relates to theory, or represents the world, at some point in time—but also model dynamics—how the model both generates new experimental results and is modified in response to them. Visual representations of structure play a central role in the theoretical reasoning of organic chemists. Not surprisingly, these representations have changed in important ways–in response to experimental and theoretical developments– throughout the history of organic chemistry. In many cases it is appropriate to understand the visual representations used by organic chemists as models. The evolution of the structural representations of organic chemists therefore provides a clear example of the dynamics of scientific modeling. In this paper I use a conception of scientific modeling drawn from the work of Mary Hesse to examine how the concept of a molecular conformation was incorporated into the visual representations of structure used by organic chemists.
