# Be consistent about working your 40 hours -- don't slack off or you
will get impossibly behind.
# Don't be afraid to ask questions -- but make sure you have at least
looked in the obvious places (i.e., searched google or read/skimmed the
documentation) before you ask your question.
-I am still working actively on !PyDy and will continue to do so as much as
possible. It is my hope that other people who study dynamical systems will
be interested in collaborative efforts to improve and extend !PyDy in order
to give it much more functionality. My most pressing goals at the moment
are to use !PyDy to derive the equations of motion for a bicycle model that
I use in my research. This is a notoriously difficult system to model
without making lots of simplifying assumptions, so if !PyDy can do it, I am
confident that it can do nearly any system that is thrown its way.

really help improve Sympy -- the more users there are to test things out,
the faster new changes get implemented and bugs get fixed.

+An important issue to me in the sciences is that of verifiability and
reproducibility. If others cannot verify your work or reproduce it, it
hurts everybody because:
+ # Nobody will be able to double check to make sure you didn't make a
mistake and people may carry on assuming your conclusions are correct when
they may in fact be incorrect.
+ # People will waste a lot of time on duplicating efforts of others if
they can't work with a common tool that is peer reviewed (Open Source) and
available to everybody.
+
+With a tool like Sympy and PyDy, people in the field of dynamical systems
now have a the beginnings of a tool which is cross-platform, free,
open-source and collaborative in nature -- this is how science should be!

Integrating !PyDy into a !MayaVi / Traits application is on my list of
things to do as well. This would be an amazing way to interact and study a
dynamical system -- visualize it, perform stability analysis, and perform
symbolic manipulations to the equations all within one place.
