[Coursera] Exploring Quantum Physics

An introduction to quantum physics with emphasis on topics at the frontiers of research, and developing understanding through exercise. Quantum physics is the foundation for much of modern technology, provides the framework for understanding light and matter from the subatomic to macroscopic domains, and makes possible the most precise measurements ever made. More than just a theory, it offers a way of looking at the world that grows richer with experience and practice. Our course will provide some of that practice and teach you "tricks of the trade" (not found in textbooks) that will enable you to solve quantum-mechanical problems yourself and understand the subject at a deeper level. The basic principles of quantum physics are actually quite simple, but they lead to astonishing outcomes. Two examples that we will look at from various perspectives are the prediction of the laser by Albert Einstein in 1917 and the prediction of antimatter by Paul Dirac in 1928. Both of these

本课程旨在深入浅出地介绍量子物理学，重点探讨研究前沿的课题，并通过实践练习来培养理解。量子物理学是现代技术的基础，为从亚原子到宏观领域的光与物质的理解提供了理论框架，并使得实现前所未有的精确测量成为可能。它不仅仅是一种理论，更提供了一种随着经验和实践而日益丰富的看待世界的方式。我们的课程将提供部分实践机会，并教授您（教材中未曾提及的）解决量子力学问题的技巧，使您能够从更深层次理解该学科。量子物理学的根本原理实则颇为简单，然而却引申出令人叹为观止的结果。我们将从不同角度探讨两个例子：1917年爱因斯坦对激光的预测以及1928年狄拉克对反物质的预测。这两个预测都是
