Even his favourite principle of dividing the excentricity in a different ratio from Ptolemy, was found to lead him into greater error than if he had retained the old bisection.
Later theories have shewn that they obey the same laws of motion as the planets, differing from them only in the extreme excentricity of their orbits.
EQ, the excentricity of the equant, had been no greater than EC, called the excentricity of the orbit.
But though I am inclined to profit by Croll's maximum excentricity for the glacial period, I consider it quite subordinate to geographical causes or the relative position of land and sea and the abnormal excess of land in polar regions.
Still," he adds, "during extreme excentricity the sun would make great efforts to compensate in perihelion for the chill of a long winter in aphelion in one hemisphere, and a cool summer in the other.
The greater the mass of the disturber and, in certain cases, the greater the excentricity of either the disturber or the disturbed the greater the effect.
Neptune, though probably less; while, if it follows a feature of the satellite systems which I have pointed out elsewhere, its excentricity should be considerable, with an inclination to match.
I hav made a kluss kalkulashun on it, and i find that there aint more than 3 men, now on earth, nor never haint been, who kan kultivate an excentricity with suckcess.
Thare seems tew be a degree of excentricityattending all, and yu will notiss this, that while the excentricitys ov a clown are quite often pleasant, the excentricitys ov a grate man are most always disagreeable.
And as our knowledge of the excentricity is derived from observation, it is, in that sense, empirical and casual.
Certainly the circumstances which determine the amount of excentricity of a planet's orbit are derived from experience, or rather, observation.
It is not a part of Newton's system to determine à priori what the excentricity of a planet's orbit must be.
Thus far had the irrational opposition of a moribund type thrown into excentricity the social equilibrium of a naturally conservative people.
If the change were to occur now, it might not be overpowering, because now the excentricity is moderate.
Well, Laplace found that the excentricity of the earth's orbit must be changing, getting slightly less; and that this change of excentricity would have an effect upon the length of the month.
Its magnitude plainly depends simply on the excentricity of the earth's orbit.
Does not the secular variation in excentricity of the earth's orbit, combined with the precession of the equinoxes, afford a key?
The excentricity of its orbit is enormous--in other words, it is either a very elongated ellipse or a parabola.
The first true perturbation is what Ptolemy called "the evection," the principal part of which is a periodic change in the ellipticity or excentricity of the moon's orbit, owing to the pull of the sun.
The excentricity of the orbit, though now decreasing, was not always decreasing; ages ago it was increasing: it passes through periodic changes.
I have spoken of the excentricity of the earth's orbit as decreasing.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "excentricity" in a variety of sentences. We hope that you will now be able to make sentences using this word.
