这个讲座问, 是否有可能通过看到或感受债券来证实债券的现实。它首先描述了20世纪初 "透视" 骗子的工作, 他们声称 "看到原子和分子结构的" 细节, 以便讨论科学信仰的适当基础。结果表明, 分子尺度并不是不可思议的小, 牛顿和富兰克林进行了简单的实验, 测量了如此小的距离。在过去的25年中, 扫描探针显微镜的各种认识使化学家能够 "感觉到单个分子和原子", 而不是键。

| 课程简介: |
This lecture asks whether it is possible to confirm the reality of bonds by seeing or feeling them. It first describes the work of "clairvoyant" charlatans from the beginning of the twentieth century, who claimed to "see" details of atomic and molecular structure, in order to discuss proper bases for scientific belief. It then shows that the molecular scale is not inconceivably small, and that Newton and Franklin performed simple experiments that measure such small distances. In the last 25 years various realizations of Scanning Probe Microscopy have enabled chemists to "feel" individual molecules and atoms, but not bonds.
