_____________________________________________________________________________

   Glasgow University has the largest Physics Department in Scotland and 
one of the  largest  in UK.  We  offer  a wide selection  of  courses  and 
options in  all  branches  of  physics and astronomy, ranging from theories 
of the origin of the Universe to practical applications of electronics  and
lasers. Physics can be combined with many other subjects - not just 
Mathematics or Electronic Engineering but even Music or Philosophy.

   Computational techniques are an important part of modern physics and the 
department has course options in this area. The main language used is 'C' 
written on PC's and Acorn computers.  Many students choose to do computing 
projects in their third year.

   These programs were originally written to demonstrate some of the
concepts  in the undergraduate lecture courses given in our department. They
were coded  in BASIC by  Dr Sandy Watt as part of an ongoing computer
assisted learning  programme. They proved  to  be useful both as  lecturing 
aids and also for  students to experiment with themselves and have generally
been well received.    

   They are being distributed in the hope that they will be equally useful
to  other educational establishments. The applications are freeware. They
may be  spread freely with all files (including  this plug for  Glasgow 
University)  intact. They may not be used or distributed for profit and no
responsibility is taken for any damage to files (of course).

                           Head of Department,
                   Department of Physics and Astronomy,

                            GLASGOW, G12 8QQ.

   For more information on these and other programs, comments, suggestions, 
improvements etc., contact the author, Dr Watt, at the same address or
e-mail  me *Mr* Luke Taylor (2/3 * PhD - his long suffering student). I can
be  contacted at the following e-mail addresses (if in doubt try them both) :

*****************************************************************************       
Release 1.1

Things have been tidied up a bit and one or two additions made:

!PtCharges - Supersedes the electric fields programs.

!Carnot - Doesn't do very much at present. Displays a Carnot Cycle in action.

!Lattices - Displays unit cells for the different lattice structures of crystals.

WaveSource - A nice basic program which shows point sources of waves (like
in a ripple tank). They can be moved about with the mouse and the wavelength
can be altered by clicking on the white bar above the display. You can
change the number of sources by altering the variable "Sources%" at the
start of the program.

Note that some of the programs work best in mode 12 (some won't work at all
otherwise) but we just haven't got round to sorting them. It's always more
interesting to do something new. If you have any problems or queries or if 
you use the programs please get in touch 'cos we'd like to hear what you 
think.

All the Best,
L.T.
