edition). Only volume 1 is needed for
Physics 105; but volume 2 is used in Physics 106, so if you’re planning to
take that course too it may be cheaper to get a book with both volumes
combined. Feel free to obtain an inexpensive used copy.

→ 21 Aug 08 - Mistake discovered! The
earlier version of the syllabus (the one the bookstore has) says on pg 2
that classes are MWF. Don't believe it! Classes are T Th, as you expected
when you signed up for this class. (Sorry about that.)

Videos of Demos
- As advertised, I will be posting videos for many of the demos. These
are high-res video files in avi format, encoded via divx. If your computer has
problems playing the file, you can try downloading this
free divx player. The down side
to the high resolution
is that the file size is large. If the large file size is a problem for anyone, let
me know and I'll see if I can downsize the video quality.

This year's exam
- Old 105 final.doc - This
is the final exam from last year, without reformatting. Read the
introductory note highlighted in yellow. Your final will be a bit
different (mostly due to the "no calculators" rule), but this will still
provide a good gauge of where you're at relative to where you need to

This is exam 4 from last year, reformatted slightly. FYI the average was
a 63. I'll try to make this year's exam a little easier.

This is the exam I gave last year, reformatted slightly. Note: I will
try to make this year's exam 2 just a little easier than last year's.
Another note: problem 21 is not something that I emphasized at all this
year. Note: an earlier version
had some minor problems with answer ranges and the like, mainly because
I didn't do answer ranges the same way last year. Also, problems 18-20
had some more serious errors. Hopefully all problems now fixed.

This is the exam I gave last year, just reformatted a little to make it
match the format I plan to use this year. WARNING: this exam had a
higher average score than I like, so I will probably make the exam this
year a little bit harder.
