So I'm working through a great Python book by Andy Harris, and I'm running a little orbit simulator.
You can the original orbit that my space ship was in (the oval shape that fits on the screen). I hit the thruster a bit too much and altered the orbit (the oval that goes OFF the screen). My ship seemed lost in space and time, as I started to think about Kepler's brilliant 2nd law. In short, if my ship was to return, it would be a while.
Python, however, deals well with really large numbers. If your program requires them, Python will supply them. Printing a googol in Python is no problemo. So I waited.
My wife came in and asked me to help her move some furniture in our guest bedroom. Later, I came back and the orbit was complete: my ship had returned home. Sometimes they come back.
