中文简介:
量子力学——即使是普通的非相对论的“粒子”这门课主要关注的公式是一个非常成功的物理理论,它无疑是20世纪科学最伟大的成就之一。它也相当奇怪——奇怪到足以让非常聪明和其他明智的人做出这样的断言:宇宙永恒地分裂成许多自身的复制品,意识头脑有能力使物理系统“跳跃”;以一种不可预测的方式,古典逻辑需要根本的修正,还有很多很多。在这门课程中,我们这些聪明和明智的人将试图冷静地看待量子力学的这些和其他所谓的含义,以及继续困扰量子力学基础的一些顽固问题。在这个过程中,我们需要大量的时间来讨论哲学问题的科学,量子力学提出了新的和有趣的方式:例如,意味着什么属性概率物理事件,科学探究的目的是什么(它瞄准真正的东西,或者仅仅是一些有用的东西?),观察的作用是在构建一个科学理论,它是什么意思说有一个“objective"物理世界,像逻辑这样基本的东西是否可以被看作是一门经验主义学科,是否存在一些有意义的科学问题,它们的答案不可能通过实验来解决,等等。
课程简介: Quantum mechanics--even in the ordinary, non-relativistic, "particle" formulation that will be the primary focus of this course--has been a staggeringly successful physical theory, surely one of the crowning achievements of 20th century science. It's also rather bizarre--bizarre enough to lead very intelligent and otherwise sensible people to make such claims as that the universe is perpetually splitting into many copies of itself, that conscious minds have the power to make physical systems "jump" in unpredictable ways, that classical logic stands in need of fundamental revision, and much, much more. In this course, we intelligent and sensible people will attempt to take a sober look at these and other alleged implications of quantum mechanics, as well as certain stubborn problems that continue to trouble its foundations. Along the way, we will take plenty of time out to discuss philosophical questions about science that quantum mechanics raises in new and interesting ways: e.g., what it means to attribute probabilities to physical events, what the aims of scientific inquiry are (does it aim at something true, or merely at something useful?), what the role of observation is in constructing a scientific theory, what it means to say that there is an "objective" physical world, whether something as basic as logic can be viewed as an empirical discipline, whether there can be meaningful scientific questions whose answers cannot possibly be settled by experiment, and more.
