Newtonian tails

I apologize for not writing any updates here in such a long time. I have been deep in research over the last couple of weeks. I have no idea why Gypsy has been lax in updating though. But I can never figure anything out with her.

About Gypsy: she has been the subject of my latest research. As we all know, kitties have tails that swish whether they want them to or not. (Watching Gypsy try to pin her tail down when cleaning it sometimes makes me wonder if she can ever control it.) As I watched Gypsy sitting on a human's lap one night recently, I couldn't help but compare her tail to a pendulum. As we all know, pendulums swing back and forth with a period that depends only on their length, not their weight. I started wondering: does a kitty's tail act the same way? If a cat's tail is swishing back and forth and a constricting object (such as a human's hand) holds part if the tail in place, effectively shortening it, does its swishing period speed up? It would only make sense that it would. Unfortunately, Gypsy's tail is both uncontrollable and unpredictable, so I don't believe this experiment could be carried out on her. Perhaps one of my colleagues at another institution could find a suitable subject?
