<blockquote><p><em>&#8220;The cat flips itself right side up, even though its angular momentum is zero.   It does this by changing its shape.   In terms of gauge theory, the shape space of the cat forms the base space of a principal SO(3)-bundle, and the statement `angular momentum equals zero&#8217;  defines a connection on this bundle. This geometric point of view on the cat&#8217;s problem gives us a deep understanding and allows us to solve it explicitly for certain model cats.&#8221;</em></p></blockquote>
