I agree with the first comment, but not with the latter.  If you are really 
going to work on the physics, you do have to have the depth in your main 
area of research.  You also need the other skills, and what is hard is to 
keep up on state-of-the-art code design while also developing new insights 
into the physics issues and getting your program optimized for 3 different 
platforms (RISC, Cray, CM-2).  And having enough time to look at tools 
like PVM so you can run massively parallel code on sets of RISC stations. 
After all, I publish in Phys. Rev. so I have to know and incorporate all 
the current literature on the subject like anyone else.

Again, the problem is that some employers like the fact that physicists 
all share a certain common base of knowledge from Newton and Maxwell to 
Einstein and Dirac.  This is an old complaint about comps.  I think the 
FSU solution, where you have a written comp on "history" followed in the 
next year by an oral comp on your proposed work and the background in 
the field of same, is an interesting attack on the inclusion of current 
research results in the graduate exams.  But the sea change is happening. 
A lot of computer work has been incorporated into our math-methods course 
at the exepense of stuff not used much today except to solve Jackson problems, 
and one faculty member even used computers in grad E+M. 

As always, one has to hash out the curricular changes since something 
has to go for everything that is added.  Students can always take the 
extra classes to learn outside their area, that is what I did, but most 
have limited time (or inclination) to do so.  Fighting over the curriculum 
is not new; one might want to change the first year course, but the great 
unwashed masses in there are mostly majors from other fields and you have 
to keep their departments happy too.  Getting them on your side may be 
the first step -- know your enemies and your allies.

Maybe.  Some of the leaders (Redish at Maryland comes to mind) are from 
the trailing edge of that group.  Lets face it, many of them did not and 
do not use computers.  They are going to retire soon; some already are 
leaving.  The problem will work its way out.
