9452099 Boness We will offer our majors in Physics, Chemistry, and in the engineering disciplines an interdisciplinary upper-level laboratory course that has as foundation an active involvement by students in the confirmation of the atomic theory of matter. The bulk of the course will build on this foundation and will consist of student projects with an atomic force microscope (AFM) and the atomic-scale characterization of conducting and non-conducting material surfaces in air, but the students will also experimentally investigate (Stefan-Boltzmann Law, Wien's Displacement Law, and relative emissivity) black body radiation, the birth mother of quantum physics, and Brownian motion (checking, as did Perrin, Einstein's derivations from his 1905 paper that did so much to silence the critics of the atomic viewpoint, Ernst Mach and Wilhelm Ostwald), all with more historical context provided in lectures, readings, and critical writing assignments than is usual in a lab course. One thread running through the whole course will be an on-going discussion of what is meant by "seeing" atoms, and the nature of experimental "proof." This course will provide needed on-campus upper-level laboratory experience with apparatus of historical and pedagogical importance as well as equipment invented even more recently than the scanning tunneling microscope (STM), which was developed in 1982 and led to the 1986 Nobel prize. In addition, Physics major Senior Synthesis projects will make extensive use of the AFM.

小行星9452099 我们将提供我们的专业在物理，化学，并在工程学科的一个跨学科的高级实验室课程，有作为基础，由学生在物质的原子理论的确认积极参与。本课程的大部分内容将建立在此基础上，并将包括学生的项目与原子力显微镜（AFM）和在空气中的导电和非导电材料表面的原子尺度表征，但学生也将实验研究（Stefan-Boltzmann定律，Wien位移定律和相对发射率）黑体辐射，量子物理学的生母，和布朗运动（检查，佩兰，爱因斯坦的推导，从他1905年的论文，做了这么多，以沉默的批评原子的观点，恩斯特马赫和威廉奥斯特瓦尔德），所有与更多的历史背景提供的讲座，阅读和批判性的写作作业比通常在实验室课程。贯穿整个课程的一条主线将是持续讨论什么是“看到”原子，以及实验“证明”的本质。“本课程将提供所需的校园上层实验室经验，具有历史和教学重要性的仪器，以及比1982年开发并获得1986年诺贝尔奖的扫描隧道显微镜（STM）更近的设备。此外，物理学专业的高级综合项目将广泛使用AFM。
