- This article is leaking a general introduction -- Mdd ( talk) 17:46, 8 May 2008 (UTC)
- I removed the technical tag and added appropriate tags. The problem isn't that the article is technical; it's that the article is written crappily. There's a distinction. -- C S ( talk) 06:12, 19 February 2009 (UTC)
I cannot figure out what the bouncing ball example is saying. I don't believe its describing the center manifold. Its not even clear what the manifold is... 67.198.37.16 ( talk) 04:23, 25 September 2020 (UTC)
- I removed it. The canonical example is Saturn's rings. Tidal forces exert the usual stretch-and-shrink mean that particles above the ring oscillate up and down (the ring thus looks like is attractive); particles in the ring have a random walk in the radius (as they gravitionally interact with other particles in the ring, exchanging energy with them during close encounters). The unstable manifold is the hyperbolic orbits. 67.198.37.16 ( talk) 04:34, 25 September 2020 (UTC)
