Recent posts (Church Logic and Church Narrative) have discussed finite  geometry as a type of non-Euclidean geometry.

For those who prefer non-finite geometry, here are some observations.

"A characteristic property of hyperbolic geometry
is that the angles of a triangle add to less
than a straight angle (half circle)." — Wikipedia

From To Ride Pegasus, by Anne McCaffrey, 1973: 

“Mary-Molly luv, it’s going to be accomplished in steps, this establishment of the Talented in the scheme of things. Not society, mind you, for we’re the original nonconformists…. and Society will never permit us to integrate.  That’s okay!”  He consigned Society to insignificance with a flick of his fingers.  “The Talented form their own society and that’s as it should be: birds of a feather.  No, not birds.  Winged horses!  Ha!  Yes, indeed. Pegasus… the poetic winged horse of flights of fancy.  A bloody good symbol for us.  You’d see a lot from the back of a winged horse…”

“Yes, an airplane has blind spots.  Where would you put a saddle?”  Molly had her practical side.

On the practical side:
