[SGVHAK] Tippe Top

[Roger Cheng]

I severely underestimated the complexity of physics behind a Tippe Top. The
more I look the more I find things I don't understand.

The "References" section of this page lists many (more than I expected)
papers on the topic, published in big-deal physics journals.
https://fysikbasen.au.dk/English.php%3Fpage=Vis&id=79.html

Even if I had access to those papers, they are the opposite of a "for
dummies" resource. I mean, look at the title of one: "*A new analysis of
the tippe top: Asymptotic states and Liapunov stability*" It's a bad sign
when my level of physics knowledge does not meet the prerequisites to
understand the *title*.

I keep looking, though...
