ellipsoidal

After all, everybody thinks the Earth is approximately ellipsoidal, and everybody can measure it.

Plenty of regulations predate the means to efficiently calculate ellipsoidal geodesics, so use great circle arcs.

When the event horizons overlap the new black hole has a decidedly non-ellipsoidal shape, so it has to become ellipsoidal and it does this through the emission of gravitational waves.

In the 1960s, he studied both the equilibrium and the stability of ellipsoidal figures of equilibrium, and general relativity.

Like another commenter said, WGS 84 uses ellipsoidal coordinates that are not suitable for the Crossrail's construction.

Any movement up or down will make its orbit more ellipsoidal than the original orbit.

The inverse of a proper ellipsoidal Mercator has no closed-form solution.

The deformation of our ~light-year sphere is very small, on the order of a few metres, and very slow, as the evolution over spherical->ellipsoidal+->spherical->ellipsoidalx cycle takes months to years.

While this is fairly straightforward for planar geometry, and somewhat harder for spherical geometry, it is not known how to implement all of the necessary predicates for ellipsoidal geometry.

That's the dream behind ceramic, hand-cast self watering planters designed with a hyper-ellipsoidal footprint, a project I've been working on for a few months now.

(say for some navigation or surveying application) you should use an ellipsoidal model or even something fancier if your requirements are very exacting.

> Commonly an ellipsoidal model is part of a more encompassing geodetic datum.

The "peanut shaped" event horizon of the new black hole will become ellipsoidal as the black hole emits copious gravitational waves.

[3] consider also the notion of having a "round heart": too strong, and your heart is very ellipsoidal...

Ellipsoidal operations are still orders of magnitude slower than the corresponding operations on a sphere.
