| * <<color("Quiz this Thursday (Oct. 11):", "red")>> as a rule, quiz will follow in the next class after homework has been turned in. Please consult my <<color("homework solutions (available for download for homework #1 -- check the Homework+ page)", "#3322ff")>> to remind yourself of key concepts that are relevant to the homework that you just turned in. Quiz will be testing those key concepts. Quiz should not take more than 15 minutes or so. * <<color("One important correction for homework problem 2(a): plane wave → sine wave.", "red")>> Please consult the updated pdf file in the Homework+ page. – ~-''<<DateTime(2012-10-08T16:00:55-0700)>>''-~ * Please note that all course materials available from this web site are debugged and updated all the time. All changes are noted, just below the download link. <<color("Also, all changes are marked red in pdf files.")>> Please make a habit of checking for them semi-regularly. If changes are made due to observant students pointing out to me the need to make certain changes, then those students may get some benefit of getting a small "lift" at the end of the quarter. For instance, such changes were just made in LN 2. Basically, I record what I perceive as "good student deeds" in my "good deed file" (not only for debugging course materials but also for other things such as asking good questions, leading good discussions and helping other students) and will consult it for a possible bump-up when students' grades lie near borderline at the end of the quarter. – ~-''<<DateTime(2012-10-06T20:06:32-0700)>>''-~ * The inquiry to possibly get a new class room has been sent. I will keep you up to date, if anything develops. – I haven't heard anything about this yet, and my sense is that we will not have luck to get a new classroom. – ~-''<<DateTime(2012-10-05T15:42:59-0700)>>''-~ |
Welcome to Phys 139B, 2012!
Welcome to the second part of Quantum Mechanics!
In this course, you will learn how to use Quantum Mechanics, now that you have thoroughly learned, in 139A, what Quantum Mechanics is. (However, we will review the essentials of the formalism of Quantum Mechanics, as we begin 139B.) The topics to be covered include perturbation theories, the variational principle, scattering, the WKB approximation, the adiabatic principle and the Berry's phase. These contents that you will learn will make you feel good, I believe, not only because you will learn to calculate things and apply your results to physical situations, but also because this process of using Quantum Mechanics will enrich your notion of what Quantum Mechanics really is all about.
