I posted the solutions for the final problem set.
Please come by my office and pick up any homeworks you have not collected.
Thanks for a fun class and
a special thanks to those of you who helped decrease the number of typos in the notes
and homeworks.

I am planning to hold lecture on Wednesday,
despite the holiday the Thursday.
Perhaps I will try to make it more flaky than usual.
Note, however, that problem set 8 is due next Monday (December 2).

2013.11.24 
For once, I was correct about a sign.
Please see the solutions to problem set 7, number 2.

2013.11.20 
I learned today that next Monday is a holiday.
So problem set 6 is due on Wednesday, November 13.

2013.11.06 
I corrected an error in the solutions of the last
problem of problem set 1. Thanks to Shenglong Xu
for pointing it out.

2013.11.04 
I have postponed the last two problems
on problem set 5 until problem set 6.

2013.10.30 
I made an important correction to the stereographic projection problem
on problem set 4.
Thanks to Frederick Matsuda
again.

2013.10.24 
I posted some small corrections to
problem set 4 (factors of c in problems 1,2 and a redefinition of e in problem
3).
Thanks to Tom Zick and Frederick Matsuda for bringing them
to my attention.
I also added an optional third part of the last problem.

2013.10.23 
I posted some small corrections to
problem set 2 problem 6.
Thanks to Frederick Matsuda and Daniel Walsh for bringing them
to my attention.
I also posted some improvements to the solutions of problem set 1.

2013.10.10 
On the homework page I've posted some great animations
made by Daniel Walsh
of the answer to problem set 1 problem 4b,
which can be succinctly restated as:
what do you see when you look out of a fastmoving spaceship?

2013.10.08 
On pages 2223 of the lecture notes I added a sidebar
in an attempt to remove the confusion about
translating expressions involving Lorentz transformations
into matrix equations.

2013.10.07 
I posted the second problem set.
It has some more special relativity problems
which I think will be helpful.
I also corrected the time of my office hours above  I had made a subtraction error.

2013.10.03 
I posted the first problem set. It is due next Monday, Oct 7.

Welcome to Physics 225A! Please look at the administrative information
posted on the lecture notes and handouts page.
Some highlights are listed below.
A comment about the waitlist:
the enrollment for the course is limited at present by the size of MH5301.
This is a good room, which I would like to use if we can.
If the enrollment continues to be too large
for this room, we will find a larger space.
