What is a flat sphere called?
A spheroid, or ellipsoid, is a sphere flattened at the poles. The shape of an ellipse is defined by two radii. The longer radius is called the semimajor axis, and the shorter radius is called the semiminor axis.
What are prolate and oblate?
If the ellipse is rotated about its major axis, the result is a prolate spheroid, elongated like a rugby ball. The American football is similar but has a pointier end than a spheroid could. If the ellipse is rotated about its minor axis, the result is an oblate spheroid, flattened like a lentil or a plain M&M.

What is Authalic sphere?
Cartographers use a value of the earth’s spherical circumference called an authalic sphere. The authalic (meaning “area preserv- ing”) sphere is a sphere that has the same surface area as the oblate ellipsoid being used.
What does oblate mean Catholic?
oblate, (from Latin oblatus, “one offered up”), in Roman Catholicism, a lay person connected with a religious order or institution and living according to its regulations; a minor dedicated by his parents to become a monk according to the Benedictine Rule; or a member of either the Oblates of Mary Immaculate (O.M.I.) …
How do you become an oblate?

What is the full meaning of oblate?
Definition of oblate (Entry 1 of 2) : flattened or depressed at the poles an oblate spheroid. oblate. noun. ob·late | \ ˈä-ˌblāt \
Why the earth is oblate?
Answers. The rotation of the earth causes the earth to swell more at the equator, compared to at the poles. When the earth rotates, there is a strong outward force on the earth matter near the equator. This force causes the swelling, and gives the earth the oblate spheroid shape.
Is an egg an ellipsoid?
The egg has been called the “perfect shape”. Analysis of all egg shapes used four geometric figures: sphere, ellipsoid, ovoid, and pyriform (conical), with a mathematical formula for the pyriform yet to be derived.
What is Earth’s true shape?
Since the Earth is flattened at the poles and bulges at the Equator, geodesy represents the figure of the Earth as an oblate spheroid. The oblate spheroid, or oblate ellipsoid, is an ellipsoid of revolution obtained by rotating an ellipse about its shorter axis.
What is oblate circle?
An oblate spheroid, or oblatum, is a rotationally symmetric ellipsoid having a polar axis shorter than the diameter of the equatorial circle whose plane bisects it. An M&M’s candy or Skittles is an approximate example of an oblate spheroid. Oblate spheroids stand in contrast to prolate spheroids.
Who are oblate priests?
Oblate Father refers to an Oblate who is a priest, notably as a member of one of the following Catholic orders:
- Missionary Oblates of Mary Immaculate.
- Oblate Fathers of St. Francis of Sales.
Do Oblates wear habits?
Often they wear a religious habit similar to, but distinct from, that of the monks or nuns. A conventual oblate may cancel this commitment at any time; and it is canceled automatically if the superior sends the oblate away for good reason, after simple consultation with the chapter.
Do you have to be Catholic to be an oblate?
One consequence is that non-Catholic Christians can be received as oblates of a Catholic monastery. Similarly in Methodist monasteries, non-Methodist Christians can be received as oblates. The same is the case with many Anglican monasteries, which accept non-Anglican Christians as oblates.
Do Oblates take vows?
You become an oblate by taking promises, akin to the vows outlined by St. Benedict in his Rule: obedience, stability, and conversion of life.
