I cannot afford the price of Mathematica for my hobby, even les as an
European customer (3185€ vs 2495$).
I am interrested in celestial mechanics and want to develop
perturbation calculations using Lagrange or Poisson brackets.
As a hobbyist, I also don't have too much time to develop the basis
for such calculations fully by myself.
I would prefer to re-use some existing package.
Therefore, I would like to know which free (or cheap) CAS software
would offer me the fastest way to start on my celestial mechanics
calculations.
Thanks
Steve Sullivan's recent FAQ for this newsgroup
mentioned a closed source (but freely downloadable)
package called TRIP that aims to be a CAS with
support for celestial mechanics:
[TRIP]http://www.imcce.fr/Equipes/ASD/trip/trip.php
I've no personal experience with it.
regards, chip
Looking at the documentation for TRIP
I could not find anything about Poisson
brackets, so this would not seem to be
as promising a lead as I'd hoped. Sorry
for the confusion.
MACSYMA would seem the best software to
try...
regards, chip
