Re: Recom on Mathcad/Mathematica

["Bernard G. Cleyet & Nancy Ann Seese" <georgeann@REDSHIFT.COM>]

There's a third alternate that Phys. (at UCSC) uses -- All the computing is done using a server (in the lab since the CATS <comp. and telecom. services> people failed to keep their server and lockers
<athena version of unix> working.)  The server has graphing, a very sophisticated non-linear least square fitting program, awk, etc. resident.  The first few lectures -- couple or hours a week for
about five weeks (-- ten week course -- typical student spends ~ ten hours a week, more when writing up labs.  APS submission quality required) are instruction on the use of the above programs -- the
students must write, in "C", modules for the NLLSq program, awk to manipulate data down loaded from e.g. MCA's for NLLSq, etc.  Peter Scott is (was?) generally in charge and did the majority of the
writing of the programs.  The students for at least one of their reports must do extensive stat. analysis.  eg. extensive use of Chi Sq. -- verify scattering and Mössb. are Lagrangian  -- algebraic
subtraction of backgrounds in counting xpts. K-K xform in the ESR apt, etc.  All w/o using store bought programs.
