Greetings SymPy Team,

My name is Aaron Miller, and I'm a third-year undergrad studying Physics and Computer Science.  I'm really interested in your projects relating to Classical Mechanics.  In particular, the task of working on an O(N) Equations of Motion method sounds like it could be very interesting.  Honestly, I'm not familiar with the Featherstone/Jain methods of forming equations of motion, but I'd love to learn it.  Is there a particular reference (paper, article, book, etc.) that is particularly useful for learning about this method?  A quick Google search turned up this paper, is that the method that I would be implementing?  Also, I know the ideas page says an ideal candidate would already be familiar with this method; would I be better off applying for one of the other Physics-related projects, or do I have a good shot at applying for this one (especially given that this one sounds more interesting to me)?

Aaron,

Both Jain and Featherstone each have a book about this subject. Last year's GSoC student worked on the Featherstone implementation. There is still an open pull request with this. I would start by reviewing what Brandon (James) did last year and figure out what it will take to finish it.

Hi Jason,

Thanks for the response.  I had a bunch of homework at the end of the week so I haven't had a chance to look at this again until today.  I've looked through the existing PR from Brandon last summer and the code he's written, and I've started looking through Featherstone's book.  It's a bit tough to figure out what the code in the PR is actually doing without having spent a lot of time with Featherstone's method.  I'm planning on getting started on a proposal but I'm not sure how detailed I can be with the timeline without learning more about Featherstone's method.  Is that going to be an issue?
