I have a branch for this already. Didn't do anything yet though; just made a notebook.
Also, I don't think I should do the PyDy intro, so if you think you want those to be together, I could NOT do this.
Do you think we should introduce rigid body dynamics with code (ReferenceFrame, Vectors, etc)? Or give a brief theory overview, then show the code to implement those concepts?
I guess I think we should show it together. Otherwise, when people are looking at ReferenceFrame they might be thinking "what was that again?" If it's together it's like enhanced documentation for the classes.

But maybe there can be a fairly brief overview without code so they can keep the stuff separate in their head, kinda. Either way, maybe one notebook is fine.

Ok, well start on what you think is appropriate and we can iterate.
Okay. Saturday morning.

What about angular velocity, angular acceleration?
Yes those are needed.
I also would like to show the v2point_theory equation because we will use that to automatically generate velocities of points on the same rigid body.
I guess you could go light on angular acceleration. I'm going to use the Kane's method class which automatically computes the angular acceleration. We just need to remind them that Kane's method does compute linear and angular acceleration.
Don't know where to put this but found this AWESOME list of ipython notebook features http://nbviewer.ipython.org/gist/theandygross/6872113
Very cool, I never thought of that. Bootstrap is pretty awesome, and really neat that it can be utilized for representations of python objects.
I can no longer commit to this.
That's fine. This is a great start.
If we decide to keep that style of figures, I will gladly make additional figures. Just let me know.
Ok, I'm definitely going to use your figures. I'm going to splice up the base notebook and figure out which other figures we need. We may only need the main figure for the example. I'll let you know.
Chris, What kind of tablet did you use? Yumi and I are thinking of buying one.

I bought it in 2011. They don't sell this particular one anymore. It's not a completely enjoyable experience. I'm often frustrated with it, and sometimes I feel like I can draw better with my trackpoint. Its size is definitely sufficient for drawing figures though. You have to get used to "draw, ctrl+z, draw, ctrl+z" till you're happy with what you've drawn. Particularly when drawing a circle; it's hard for me to end where I started. For all the handwritten text in the figures, it took 2 or 3 writings before I was happy with how it looked. Handwriting is definitely the hardest to get to look nice.
I wonder if they're going to go out of business, with the growing prevalence touchscreen laptops.

I don't think this will go out of business, but the pads should display what you draw so you can close a circle correctly. That has to be technologically possible.
Touchscreens can only offer finger paiting resolution, I suspect. But i guess if the pressure sensitivity is in the pen that you can draw on a touchscreen table too.
Hmm. I wonder if we should buy one.
You may be able to borrow one from your library to try it out.

What is the status of work on this notebook? It is incomplete. I hope you weren't expecting I was going to finish it =/
No I wasn't. I'm working on it. I have a branch with some changes. The notebook is great, my only worry is that I may not be able to make the final sections as nice as you did! I'll try.
Oh shush. Did you end up buying a tablet? I'm happy to make figures. Also, remember the LaTeX macros at the top.
I added some content to fill things out in b2e52475b1a2edfd1d60a57b0eae11befb6ad33f, I'm going to try and add some more this evening to improve what I wrote.
Ok, this is as good as it is gonna get for now.
