Changes in CHIP #21 (due Aprl 8) and CHIP #22 (due April 10) Fri 28Mar2008 12:03PM
For those of you who already started working on CHIP #21 (due April 8) and CHIP #22 (due April 10), we apologize for inconvenience, but we moved a problem from assignment CHIP #21 to CHIP #22 and correspondingly, moved a problem from #22 to #21. We also added a new problem to #21 and dropped two existing problems from #22. (if you already any of these problems, your answers and scores on the problems which have been moved also moved), So if you already started on them, please recheck to find out which ones you still have to work on.
Exam II coverage of Chap. 30 "Maxwell's Equations and Electromagnetic Waves" Thu 27Mar2008 12:05PM The topics of the last 4 slides of Lecture 21 ("Energy Density", "Energy Propagation", "Radiation Pressure" and "Maxwell's Rainbow") will not be asked in the upcoming Exam II as Nakanishi had no time to discuss them in his lecture. Also, since the treatment of Chap. 30 has been light, we will be asking just one question on the Exam II from the material in that chapter. (However, your recitation will discuss these issues as there are homework questions related to them. Also, the Final Exam will potentially cover them.)
Exam II Locations Thu 27Mar2008 8:59AM
Exam II will be given during 7:00 pm - 8:00pm on Wednesday, April 2.
For Exam II, please report to the same location as you did for Exam I.

Typos found in Tipler text Tue 18Mar2008 5:56PM A student found typos in our Tipler text. On p.976 in second to last sentence and again on p.977 in the second equation from top, the magnetic flux "(phi)_m2" should be replaced by "(phi)_m2,1". The authors appeared to have forgotten that "phi_m2" was defined differently eariler on p.976.
Problem "Iron-core Solenoid" moved to CHIP#16 Tue 04Mar2008 5:25PM One of the problems that used to be in CHIP#15 (due Thursday, March 6) has been moved to CHIP#16, together with all answers you may already have submitted and all scores you may already have for that problem. This is due to the fact that neither Prof. Xie nor Prof. Nakanishi covered the topic of relative permeability in the Tuesday lecture.

Misprints in the Tipler text found Fri 18Jan2008 10:55AM
There are some misprints on p.734-735 of our text. On p.737, in Step 6, the electric field E should be
kQz/(z^2+a^2)^(3/2)
The exponent in the denominator should be 3/2 NOT 3 as printed in the book. The same error also occurs at the bottom of p.735 and at the top of p.736. (We had the correct formula given and discussed in the lectures.)
