Randy, you have two different notebooks, which one are we supposed to read? If both in which order? You need to tell us, because the original idea was having 1 notebook. Please give us some guidance so we can read you project and give you some feedback.

The notebook was getting too long, so I split it in two parts. The first is
called Integration techniques for mechanical systems, and the second is
called double pendulum problem.

On Integration of Mechanical Systems

• In RK4 you say, for more details see (cite). Can you specify which all of the citations is the one that correspond to this part.
• In the function RK2 the docstring says "Runge Kutta fourth order integration method" it should be second order.
• When you plot the legend on the plots, you can choose where to put it so it doesn't disturb the plot. Check this link http://stackoverflow.com/questions/4700614/how-to-put-the-legend-out-of-the-plot
• In the screen shots you are presenting (32 bit vs 64 bit) I think it will help if you put in the title of each figure which one is 32 and which one is 64.
• In the L1-norm plot,we need a legend, it makes easy to read the plot, otherwise we have to go to the previous one and compare the colours.

*In the energy in damped HO plot and the phase portrait, RK2 and RK4 don't appear, why? Are they overlapped?

• You should have a conclusion title or something to finish up the lesson, or a connection with the second notebook.

typos:

energy, Conservation ---> energy. Conservation (or conservation in lower case)
here, the we can -------> here, we can

On Double pendulum : no comments.

Really interesting work!
