Week 12 Reading Responses

Posted on by

You can find the Reading Response Rotation assignment in the PSAM Community folder, available by clicking here.

I’m still working on a good solution for submitting your responses. We’ll try out another method which will be available by Sunday morning. In the meantime, compose your responses to the prompts below in a separate document, and you can copy/paste those responses into the Reading Response form once it is available. Please use very simple formatting.

Prompts: for each section (Taylor, Townsend) or sub-section* (Griffiths), answer the following questions.

  1. Big Concepts: For the relevant sections, what are the main physics concepts/ideas? Make sure to also note which (if any) physics concepts are new to you. (Try to just use words here and minimize invoking equations, but don’t stress if you find it more convenient to use or refer to an equation.)
  2. Big Maths: For these sections, what are the major mathematical tools/formulas? Make sure to also note which (if any) math concepts or methods are new to you. Here, feel free to refer to equation numbers or page numbers, and do your best to convey the meaning of the equations in everyday language. Again, don’t stress if you find it more convenient to use technical rather than everyday language. Make sure that you have the important equations clearly written out and explained in your reading/lecture notes.
  3. Big Questions: As specifically as you can, describe in detail your questions/confusions from the section/sub-section, about physics concepts, math moves, and particularly (but not limited to) any Examples in the section/sub-section. In essence, what in particular would you like us to spend class time going over?

* In the notecard feedback from last week, someone mentioned that they would rather respond to sections in Griffiths, rather than sub-sections. So for this week’s reading, let’s try to lump these together:

  • 2.1.1 and 2.1.2 and 2.1.3
  • 2.1.4
  • 2.2.1
  • 2.2.2 and 2.2.4
  • 2.2.3

Reading:

  • CM: Taylor 2.1 – 2.4
  • EM: Griffiths 2.1 – 2.2
  • QM: Townsend 2.1 – 2.5; 2.8 up to eq. (2.134)

QM on Thu. Jan. 10

I might be late to QM on Thu. Jan. 10.

If I am not to class by our start time at 9:30, please form into workshop groups and work on this week’s QM homework together.

Please remember to begin by checking in with each other and establishing community agreements.

When I arrive, we will finish our discussion on calculating ΔSz, and then we’ll go over Problem 1.3.

QM Problem Set #1

Posted on by

QM PS#1 (Townsend): 1.8, 1.9, 1.10, 1.11, 1.12, 1.13, 1.14, 1.15

Notes:

  • You need the results of Problem 1.10 for 1.11 and 1.12. You can check your results for <Sz> and <Sy> as directed in the problem statement. You should find that <Sx> = 0.
  • Problems 1.4, 1.5, 1.6, and 1.7 will be assigned as part of QM PS#2, so after completing this week’s set, you may choose to begin on those problems. We will complete Problem 1.3 together during class on Thu. Jan. 10; Problems 1.4-1.7 are based on Problem 1.3.
