  * '''Midterm is over.''' Check solutions and fill in the gaps of understanding, if possible. It would continue to matter for the final exam, since we will continue doing waves, and interference, and so on, just with a different wave (light) for the next few lectures.&mdash;~-''<<DateTime(2014-02-14T17:09:28-0800)>>''-~

Welcome to Physics 5B, 2014!

  • The final progress report has gone out to each of you! I think most people did well in this course—congratulations! Whether you are satisfied with your outcome of this course, whatever that may be from your personal point of view, please keep in mind that there is much more to learn down the road, and probably the most important thing that you should be learning at this point is the correct approach to acquiring knowledge.—2:33PM, Mar 26, 2014

Welcome to the second part of Physics 5!

In this course, we will continue the exploration of the introductory physics. We will start with the simple harmonic oscillator. Then, we will study waves in general. This will lead to geometric optics and related topics. Lastly, we will come back to fluids and statics. If we somehow run out of time, we might leave some topics like fluids for reading only. I like to go through the simple harmonic oscillator and waves, slowly but surely, so that we cover these supremely important topics well enough.
