PH253: server issues

UPDATE 2: with the server being down, Moodle is also down until further notice. Hopefully it will come back up some time today. Also, a draft of the formula sheet for the final.

UPDATE: HW and Exams mirrored here. The additional notes as well (well, most of them, until I hit my quota on bama.edu. Lame.)

For what I hope to be a short while, old HW/exams/etc are unavailable, owing to some script kiddie messing with the server I'm using:

I just got word that the machine that runs the faculty websites has been hax0red, so we have to take it offline till we can figure out what happened.

I will try to get a mirror up later this morning.

HW2 Bugfixes

Homework 2 has been updated (minor) - in particular, #4b was redundant and has been removed, along with a few typos.

PH253: Supe store fail

I realize the supe store is still out of the textbook, and that really sucks. They have more copies on the way. In the mean time, just about everything you need to know for relativity can be found in Ch. 1 here. That is ... you have all you need to do the current homework set already. Also, this.*

If you still do not have a copy of the book, see me after class. I will either give you a loaner or make photocopies to get you through the next days, i.e., quantum behavior.

*You should always assume that professors recycle questions, and see if you can find content they used in previous semesters. Just use it wisely, or the exams will eat you alive.

PH255: lab manual

It turns out that I had set some permissions incorrectly, and the password protection for the lab manual was not working correctly for a while yesterday.

Rather than messing around with linux permissions and .htxxx files (it is not 1990 anymore), I've just password-protected the PDF for the lab manual itself. All of the links at right are now unrestricted, but when you download the lab manual, you'll need a password to open it.

Same password I gave you yesterday in class ...
