- Hans Liu's office hours this week and next:-
- No office hour Friday 4/26, 4pm to 5pm
- Office hour today, (4/25), 4pm to 5pm.
- No office hour Friday 5/3.

- If anyone needs advice before Drop Date please send me an email message.
- Solutions to Test2 are below.
- Forgot to change the pointer to the new version of the test problems, done now!
- Added a hint to P2.5 since I gave a similar (but actually different) hint to some people this afternoon. Three questions on the test tomorrow.
- No Office Hour at 11AM 16 April, 2013, but 4PM is possible -- or write and ask for another time.
- 16 April, 2013: New version of Test2-pre, only notational changes.
- The problems from which Test2 will be selected are up -- I will need to read them again later today so the list should not be considered as quite final.
- Typos fixed in Problem 6, 12 April, 2013.
- Problem set 6 is up. After a little debate, I decided to postpone the due date for PS6 until 12 April.
- Okay, so Problem 5.3 -- or the sufficiency part -- is probably too hard without a bit more of a hint; in the latest version below I have added one.
- 24 March, 2013. It seems that I did not update the problem set correctly, I think it is fixed now; this mainly concerns Problem 1. Thanks Emilio.
- Problem set 5 is up, due March 29. However I put up the wrong version -- changed later the same day to v2.
- 15 March, 2013. I have finished grading the tests -- everyone who took it did well. They will come back to you via email.
- Inclass test today, 12 March, 2013. Three of the questions from the list below plus an extra problem for the bored (don't do it until you have done the other three it may not be worth anything!)
- Problem set 4 is up.
- Lecture 7: 5 March, 2013. Hilbert space to convergence of Fourier-Bessel series.
- Third problem set up
- Lecture 5: 21 February. Proved existence of Lebesgue integral.
- Thanks Andrew for pointing out the failed link to the second problem set.
- Second problem set up, 16 February, 2013.
- If you did not get a message from me your Problem set 1 probably did not arrive -- so ask.
- Lecture 4: 14 February. I finished a superficial discussion of completion and started Lebesgue integration.
- First problem set up, 9 February, 2013 -- normally I will get them up a bit over a week in advance.
- Someone, probably from 18.102, left an LG smartphone in 6-120. If you would like it back, contact Nancy Boyce, Course Manager for Physices in 4-315.
