American Heritage® Dictionary of the English Language, Fourth Edition
- n. A body that is shaped like a sphere but is not perfectly round, especially an ellipsoid that is generated by revolving an ellipse around one of its axes.
Century Dictionary and Cyclopedia
- n. A geometrical body approaching to a sphere, but not perfectly spherical.
- n. In geometry, a solid generated by the revolution of an ellipse about one of its axes. When the generating ellipse revolves about its longer or major axis, the spheroid is prolate or oblong; when about its less or minor axis, the spheroid is oblate. The earth is an oblate spheroid—that is, flattened at the poles, so that its polar diameter is shorter than its equatorial diameter. (See
earth, 1.) The same figure is assumed by the other planets; hence the properties of the oblate spheroid are of great importance in geodesy and astronomy.
- n. In anthropology, a cranium of nearly spherical form.
- n. A solid of revolution generated by rotating an ellipse about its major (prolate), or minor (oblate) axis.
- adj. Of a shape similar to a squashed sphere.
GNU Webster's 1913
- n. A body or figure approaching to a sphere, but not perfectly spherical; esp., a solid generated by the revolution of an ellipse about one of its axes.
- n. a shape that is generated by rotating an ellipse around one of its axes
“The effect of graviational radiation on the secular stability of the Maclaurin spheroid', Astrophys.”
“The labours of Fernel and above all of Picard, upon the measure of a terrestrial degree between Paris and Amiens, had made it clear that the globe is not a sphere, but a spheroid, that is to say, a ball flattened at the poles and swollen at the equator, and thus were found at one stroke the form and the dimensions of the world which we inhabit.”
“At the flat end of the spheroid was a small ring of a pink colour, from which ran lines forming the ribs, which supported the sides of the animal.”
“Page 548, Volume 1 weaker than at the less distant poles, and Huygens 'pendulum clock should beat time more slowly at lower latitudes than at higher latitudes on this oblate spheroid which is our earth.”
“You'll see the Earth is curved but it won't be, 'We live on this oblate spheroid!”
“Part of the play's appeal today is nostalgic: it evokes an era when football reporters talked of "agitating the spheroid to the sticks" and when a star centre-forward, bent on self-improvement, could say "there's things in Browning I can't figure out and Walter Pater has me beat to atoms.”
“Then idly he rolled a dimpled spheroid around the palm of his hand.”
“Therefore, we—as the children of monkeys who fetishized symmetry and evenness—inherited a desire to live in a perfectly round world instead of a flat-topped oblate spheroid; to want planets that traveled in perfectly round orbits instead of weird egg-shaped ellipses and an Earth that looked like an inkblot with the equator as the fold.”
“She's also not great looking-her skin's a little sallow and either through genetics or lack of maintanence she's cursed with an enormous frizzy Jew fro, which she always wears bobbling back and forth in a gigantic spheroid on top of her head.”
“Although there is a small chance (measured as the length of time a roughly-packed spheroid of frozen dihydro-monoxide would survive in Hades) of some shred of one of these plans surviving in the House/Senate conference on the healthcare reform bill, I'm not exactly holding my breath.”
