This document will be updated throughout the course; entries are in
reverse chronological order.

The xfpp3d utility now accepts a -c option that allows the
displayed particles to be colored in a user-specified fashion. See
the on-line documentation HERE for more details.
Thursday, November 21, 6:00 PM
The location of the final exam has now been announced. It will be in
HEBB 10, Dec 10, 12:00 PM.
Sunday, November 17, 12 Noon
Mpeg generation capability has been added to both xfpp3d and xflat2d.
See HERE for details.
Friday, November 8, 4:15 PM
Usage of the lnx boxes is intensifying and there have been some problems
lately with machine hangs, re-boots etc. In order to minimize frustration for
all, please e-mail me IMMEDIATELY if you encounter a "frozen" machine.
Wednesday, November 6, 2 PM
The Term Project PAGE has been updated to include links to
documentation for visualization programs likely to be useful for various projects. Note
that this documentation is still under development, particularly in the case of xvs,
so if you have any questions, or encounter any problems, send me e-mail as usual.
In addition, for those of you studying the KdV equation (solitons), I have added a link to
a summary of Newton's method for nonlinear systems of equations.

The handout for Homework 4 is now available. I will distribute hard-copy in tomorrow's class.
Wednesday, October 23, 7 PM
The preliminary
EXAM SCHEDULE is now available.
Tenatively, our final exam is scheduled for
TUESDAY DECEMBER 10, 12 NOON

There will be another power outage in Hennings this weekend from
FRIDAY, OCTOBER 25, 11:00 PM TO SUNDAY, OCTOBER 27, 11:00 PM
During this time the lnx machines, as well as
laplace.physics.ubc.ca (the machine which serves the course
Web pages) will be unavailable. physics.ubc.ca, on the other
hand, should remain (remotely) accessible.
Friday, October 11, 11 AM
Further to Monday's news item, the power outage in Hennings is
now scheduled for
FRIDAY, OCTOBER 11, 11:00 PM TO MONDAY, OCTOBER 14, 11:00 PM
During this time the lnx machines, as well as physics and
laplace.physics.ubc.ca (the machine which serves the course
Web pages) will be unavailable.
Tuesday, October 8, 12 Noon
Ryan has pointed out that there is a
notational ambiguity in Homework 2, Problem 2.1. The expression to
be differentiated is
( cos(ln(3x+6)/y) )^2
not
cos( (ln(3x+6)/y)^2 )
The online handout has been updated to make
the intent clear.
Monday, October 7, 3:30 PM
Please note that there will be a complete electrical shutdown in the
Hennings building from
FRIDAY, OCTOBER 11, 9:30 PM TO MONDAY, OCTOBER 14, 12:00 AM
During this time the lnx machines, as well as physics and
laplace.physics.ubc.ca (the machine which serves the course
Web pages) will be unavailable.
Sunday, October 6, 6:30 PM
Plato has pointed out the following
typo in Homework 2, Problem 3. In the description of lpair:
whose i-th element is the 2-element list [ l1[1] , l2[i] ]
^
|
should read
whose i-th element is the 2-element list [ l1[i] , l2[i] ]
^

The online handout has been updated.
Monday, September 30, 3:30 PM
The handout for Homework 2 is now available. I will distribute
hard-copy in tomorrow's class.
Monday, September 16, 8:00 PM
Two items relating to Unix and, in particular, to the first homework:
-
ADDITIONAL HINT FOR HW 1.7: Consider the following printf usage example:
% printf "%s %s %s\n" 1 2 3 4 5 6 7
1 2 3
4 5 6
7
-
As a follow-up to the previous News item, a section on the command-line
use of the control character ^V has been added to the
Unix notes.

Alexandra has brought to my attention the difficulty
in specifying a
TAB character in the context of a shell command line, which is
nominally required to complete Problem 4 of Homework 1. Consequently,
that problem has been changed to read as follows:
In a directory ~/hw1/a4, create a file called compressed whose contents
are identical to ~phys410/hw1/q4/input except that all lines which
contain only spaces have been removed.
I.e., your solution no longer has to detect TAB characters in the input
file, and, indeed, I have modified ~phys410/hw1/q4/input so that
it contains no TABs. The online version of the homework, available
HERE has been updated to reflect this change.
If you have already completed this problem, I request that you redo
it in view of the new specification---this should be very straightforward,
and will make the grader's like easier.
Friday, September 6, 12 noon
The handout for Homework 1 is now available. I will distribute
hard-copy in next Tuesday's class.
Thursday, September 5, 3:30 PM
I have created the following accounts on the
lnx machines:
mnhoff cliew murray dwalters
Refer to the previous message for additonial information.
Tuesday, September 3, 8:30 PM
I have created the following accounts on the
lnx machines:
carmitag jake kcheng sdavis hossain
soonlee pletourn pleung jlindahl bruno
cdneish pope jrosales hseetzen rmshanno
tiffanan suresh btippett
If you wish, and if your account appears in the above list, you should now be able to
ssh into the lnx machines from a remote host via any one of
ssh userid@lnx1.physics.ubc.ca
ssh userid@lnx2.physics.ubc.ca
ssh userid@lnx3.physics.ubc.ca
where userid is to be replaced with your own user id. You should
also be able to login into the lnx machines via their consoles
in Hennings 205. Your password should be the same as that for your account
on physics.ubc.ca. If you have any difficulties logging in, and
if the NOTES concerning machine
usage are not sufficient to solve these problems, let me know via
e-mail immediately.
