OK, thanks

"Why is that?", asked the naive newby.

Thank-you, I will get that book at the library.

Yes, the Euler's disc is what I'm talking about, although I use a Correlle cereal bowl; it's light weight seems to make it better suited for this motion. I wish I could find out if this kind of motion has ever been applied in a mechanical or electrical device. Seems to me, the fact that the...

By "wobble" I'm talking about the undulating movement of the outside edge of the bowl as it spins...not sure if that's the same as precession or not, maybe it is. The outside edge of the bowl does a lot more "traveling" than the bowl would if it were simply spinning, like a record on a record...

When you spin a bowl, for instance, and it wobbles as it spins in circles. I've always been captivated at this motion, and have never been able to find the name for it. Sounds silly, but I think there's an un-tapped (as far as I know) force at work there. Thoughts? BTW, I'm definitely not in HS...

Hi, J Hawthorne here. I don't have a formal education in Physics, but have always been drawn to it and look forward to learning. Hope you don't mind if I sometimes ask a "rookie" question...thanks.
