Webstructure of a truncated isothermal sphere. Students sometimes suppose that isothermal regions in stars will have constant density, but this is not the case. The density must increase toward the center to satisfy the equation of hydrostatic equilibrium. While the star is burning hydrogen in its core, the temperature is highest at the center.

The design on the backside of the opening looks almost like a simple design of a sun. I'm not 100% sure the bottom picture is inside the top sphere, but I think it's a safe bet, they seem to be of similar size, and the opening architecture at least is the same on the edge.

Webvalid in 3 and 7 dimensions (which shows that u × ( u × v) = − v for u ⊥ v and u = 1 ). Therefore J x ( u) = ν ( x) × u indeed defines an almost complex structure J x: T x Σ → T x Σ. Specializing this to Σ = S 2 embedded as unit sphere in Im H you can “see” (or calculate) that J x acts in exactly the same way as multiplication by i on C P 1. http://www.map.mpim-bonn.mpg.de/2-manifolds
