 * In today's class, some discussion about the computer algorithm has seeped in. In the process, the two things (binary search (or bisection search) and quick sort) were sort of mixed up. Please check "DF" above to see a cleaner discussion of this. In particular, Nathan's comment on the quick sort algorithm speed ''was'' correct! Sorry about any confusion that you might have had! &ndash; ~-''<<DateTime(2013-02-01T11:22:27-0800)>>''-~  * My extended office hours are on Wednesday (Mar 20; 11AM -- 5PM) and Thursday (Mar 21; 9AM -- 5PM). &ndash; ~-''<<DateTime(2013-03-19T07:33:37-0700)>>''-~

 * I am pretty sure that I made this slip today. So, let me correct it. On the blackboard, as I was answering A, I drew an inverted evacuated tube immersed in liquid, and indicated how high liquid will rise in that tube by 1 atm of pressure. Hg &rarr; 760 mm (''not'' 76 mm) -- this is why 1 atm is 760 mm Hg (= 760 Torr). Water &rarr; 10 m. My lecture notes and review sheets had been fine on this. It is just that on the board I quickly wrote an incorrect number, I think! Sorry, if this confused you. &ndash; ~-''<<DateTime(2013-03-18T13:58:06-0700)>>''-~

  • I am pretty sure that I made this slip today. So, let me correct it. On the blackboard, as I was answering A, I drew an inverted evacuated tube immersed in liquid, and indicated how high liquid will rise in that tube by 1 atm of pressure. Hg → 760 mm (not 76 mm) -- this is why 1 atm is 760 mm Hg (= 760 Torr). Water → 10 m. My lecture notes and review sheets had been fine on this. It is just that on the board I quickly wrote an incorrect number, I think! Sorry, if this confused you. – 1:58PM, Mar 18, 2013

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.
