A summary of useful weblinks:
- Email Dr Joan Adler
with general questions.
- Email Dr Joan Adler
with your targil solutions.
Class email list.
- With fortran and c we will be using
and a listing of the different subroutines can be found on the local
If you need help on Targil 1 or 2 on random walks I will give at the end of class today.
I can also discuss projects then.
The project can be related to your thesis research, e.g.
a model simulation if you are an experimentalist or a numerical example
of your theory if you are a theorist, but not part of your
thesis research. It could also be related to the course you are
teaching, or to something that interests you in another course you are taking.
project information page for more details.
Please everyone check you have a working account and password on tx/t2
the problems last week were due to a bug in the computer that checks passwords; I should have realised this.
If you want to know more about pgplot and view examples
of different interfaces,
two sample pgplot
programs are listed on the
http site. Some of these as of now still require adaption to gfortran.
The programs are ready to be compiled, please note that pspell.f needs the
file param.e7 to be present in the same directory.
You should also look at
targil5 page some time soon and start completing the tasks listed there.
Printing: sometime this week a printer called bw is moving to Rm 315.
It can be accessed from phelafel in one of 3 ways to print the file called ``cat'' or `` cat.ps ''.:
Since it is my printer, I'd appreciate using it for class stuff only, and email me if there are problems. The printer is meant for physics department undergrads since there seem to be issues printing in the library.
- remotely, if you are ssh'ed into phelafel by either the command lpr -P bw cat.ps for a postscript file.
- remotely, if you are ssh'ed into phelafel by either the command enscript -P bw cat for an ascii file.
- from a browser or acrobat reader or PrtSC button on the phelafel screen.
For those of you who have not taken a class in analytical mechanics, you
need to prepare for the lecture after the next one by
looking at one of the
texts of this class or asking one of the physics
students to explain a bit about Hamilton's equations.
This week we will continue
learning about the different types of Computational Physics:
turning to the three main techniques of numerical analysis
that are used for the solution of equations. These are
quadrature and finding
The reference material is chapter 1 of Koonin (and Meredith).
You can view this text at this link:
I expect different levels of knowledge about these depending on
students' backgrounds, and recommend careful reading of this chapter 1
of you who feel you need extra help.
Useful programs for doing these operations are
can also be downloaded (see instructions) as a tar file like we did last week.
All these programs (e.g. name.f) do not need pgplot so can be run on any unix system, and are compiled with gfortran name.f -o name.ex
This weeks material forms the basis for question 1 of the
third targil, . You will not be able to answer question 2
(based on chapter 2 material)
until at least the next lecture, if not the one after, but it is a good idea
to get started on question 1 already this week.
Time permitting we will stop 15 mins early for the tasks listed above and also
so those who need help starting
their webpages can get it. If you already have a page you will be excused;
if you need more help stay on. The first thing you need is an account on
phelafel., which we will call ``username''. Then you need to go into it and do
the commands on webpage.html.
Then scp, but with webpage.html instead of a tar file into the directory public_html, the
Then you edit this page with your info and a photo.
If you call it index.html your address will be http://phelafel.technion.ac.il/~username".
Please nothing illegally copied (like music), commercial, political or unsuitable.
Feel free to put
anything else there.
