This is an introductory course on the generic properties of vibrations and waves, including both discrete and continuous media, with application across a broad range of phenomena and fields. Lecture demonstrations will be used to introduce and develop the concepts. Abstractions and concrete examples will also be discussed.

By the end of this course, you will be able to:

Frank Porter

348 Lauritsen, Ext. 6777

Office Hour: After lecture, or by email/appointment

Ashmeet Singh

414 Downs-Lauritsen

Office Hour: Monday 7pm, Downs-Lauritsen 414

e-mail:

Meagan Heirwegh

156 Linde Hall, Ext. 4336

e-mail:

George King, *Vibrations and Waves*

It is well-written and an excellent match to the desired content of the course. We
should be able to get through it all. The text is also available on reserve in Sherman Fairchild Library.

You are encouraged to find a recitation section that is both enjoyable and beneficial. If you are dissatisfied with your assigned section, feel free to sit in on another one. If you decide to change sections, get the signature of the instructor of the new section, on your yellow card. Section times and locations are available on the the Sections, Office Hours and Grading Schedule tab above and also the registrar's webpage (http://schedules.caltech.edu/FA2018-19.html#dept_details_PHYSICS).

Homework will be due at *11 am on Tuesdays* (just before lecture), in the **homework box outside 201 E Bridge** and returned to a group location (the return cubbies in Bridge Annex) if you've filled out the FERPA; otherwise they can be picked up from Meagan Heirwegh in 156 Linde Hall. Assignments are listed on the Homework/Solutions tab above. Solution sets will be posted on the web one week after the homework is due. You are strongly encouraged to check your work when it is returned to you. Problem sets are essential for mastering the material in this class! You are encouraged to approach and solve problems in a comprehensive way, focusing on the ``flow of thought and logic" instead of just getting the final answer ``right". Have a look at some guidelines and an solved example problem to help you approach problems better.

Under the theory that you learn best by doing, the problem sets will be heavily weighted. The plan is to compute grades based on:

Component | Percent of grade |
---|---|

Homework | 70 |

"Quizz" | 10 |

Final (individual) | 10 |

Final (group) | 10 |

In the hopes that it will be a bit more fun and motivating, we are changing somewhat from the traditional sequence of quizzes and final as well. For the "quizz" we will arrange for one recitation during the quarter to be a flipped section, with students doing the problems. Grading on this will largely amount to a "participation grade", i.e., not so much on getting the right answer as on effort. The final is proposed to be in two steps. We'll work out the details as we get closer, but the idea is along the lines of: Everbody does the final as an individual, and gets an individual score. The class will be divided into small groups (randomly, we plan), and each group will collaborate on the final and turn in a group exam for a group score. Everyone in the group gets the same score for this. If someone gets an individual score higher than their group score (we hope this doesn't happen), they will be protected in the sense that the higher of their individual and group scores will be assigned as their group score.

We will be using **Slack** as a collaborative and interactive online workspace where you can ask questions, discuss concepts and brainstorm with the course instructors and your fellow classmates. Don't slack in using Slack! To join our Slack workspace, register with your Caltech email (The restriction is that you must have a Caltech IP address (use VPN if needed).) at: https://join.slack.com/t/ph2a2018/signup and after which you can access it at https://ph2a2018.slack.com. You should also download the Slack app on your phone and stay connected with all the awesome physics Ph2a has to offer!

We are also using **Piazza** as a platform to encourage questions and discussion. And yes, you can post anonymously here (unlike Slack). Please join the class' Piazza here.

Ombudsfolk are student volunteers who represent the students of each of the undergrad houses. They collect suggestions, comments, complaints, etc, and discuss them with the course instructor and TAs at periodic meetings (free lunch!). Talk to your ombudsperson! Each house should select an ombudsperson. Prof. Porter and the recitation TAs will have lunch with the Ombuds on **Tuesday, 10/16 at noon** and then again on **Tuesday, 11/6 at noon**. Students are also encouraged to discuss any problems regarding the course, directly with Prof. Porter, or head TA, Ashmeet after lecture/recitation or by appointment.

Collaboration is encouraged and and is intended to reflect real-life problem-solving experience. A good practice is to first give problems a good try by yourself. Then maybe you will have the satisfaction of explaining it to your colleague. However, whatever you turn in should be what you think you understand. Imagine someone asking you to explain it. If you use some resource on the web for a problem, reference it!
