Yikes! Hmm, this probably won't help the non-physics majors
among our program users... (: Is there some way to
identify, for example, the largest meaningful value for
stretchability, as a function of the other variables
involved (whatever they may be), in a reasonably typical
range of cases?
I mean, if I double the stretchability value, the space will
stretch "twice as easily"? What does that mean? If I want
the space to stetch "effortlessly", should I set the value
to +inf.0? And how should I expect the space to behave when
it's stretching "effortlessly"? This is all so abstract to
me...
