"Ellipse" Quotes from Famous Books



... of their distances." From the second law of Kepler, namely, the proportionality of the areas to the times of their description, Newton inferred that the force which keeps a planet in its orbit is always directed to the sun. From the first law of Kepler, that every planet moves in an ellipse with the sun in one of its foci, he drew the still more general inference that the force by which the planet moves round that focus varies inversely as the square of its distance from the focus. From the third law of Kepler, ...

... after. Fame appeared on the horizon. Critics rose and thundered. Balzac defied all rules, walked over the grammar, defiled the well of classic French. He invented phrases, paraphrased greatness, coined words. He worked the slide, glide, the ellipse—any way to express the thought. He forged a strange and wondrous style—a language made up of all the slang of the street, combined with the terminologies of the laboratory, law, medicine and science. He ...

... a lurid glare over the vast field of snow; but, as if it too were under the control of the Arctic Spirit, it was nothing more than the mockery of a moon, and was constantly assuming the most fantastic and varied shapes. Now it extended itself laterally into a long ellipse, then gathered itself up into the semblance of a huge red urn, lengthened out to a long perpendicular bar with rounded ends, and finally became triangular. It can hardly be imagined what added wildness and strangeness ...

... formal sunken garden, at which you pause, is the greatest beauty of the Villa Pamfili Doria. You stop to look at it by the impulse of your coachman, and then you keep on driving round, in the long ellipse which the road describes, through grassy and woody slopes and levels, watered by a pleasant stream, and through long aisles of pine and ilex. We thought twice round was enough, and told the driver so, to his evident surprise and to our own regret, so far as the ...

The main entrance was in the centre of the front—a low arch that seemed half an ellipse. No one was visible, the doors stood wide open, and I went unchallenged into a large hall, in the form of a longish ellipse. Toward one side stood a cage, in which couched, its head on its paws, a huge leopardess, chained ...

... a weapon with a fission yield of 1 million tons TNT equivalent power (1 megaton) exploded at ground level in a 15 miles-per-hour wind would produce fallout in an ellipse extending hundreds of miles downwind from the burst point.

At a distance of 40-45 miles, a person would have ...

... individual life, and so have been unable to explain apparent anomalies, especially in those cases where it is seen that the effect does not immediately follow the cause. In reality, every force that emerges from a centre of will[23] describes an ellipse, so to speak, which travels through a net-work of other ellipses generated by thousands of other centres of energy, and is accelerated or retarded in its course, according to the direction and nature of the forces with which it is connected. It is for this reason that certain actions meet with their ...

... attract one another at all, but only moved under the influence of the sun, they would move in orbits having the form of ellipses. They are found to move very nearly in such orbits, only the actual path deviates from an ellipse, now in one direction and then in another, and it slowly changes its position from year to year. These deviations are due to the pull of the other planets, and by measuring the deviations we can determine the amount of the pull, and hence the ...

... second class, of those lines whose nature is to proceed for ever into space. Any portion of a circle, for instance, is, by the law of its being, compelled, if it continue its course, to return to the point from which it set out; so also any portion of the oval curve (called an ellipse), produced by cutting a cylinder obliquely across. And if a single point be marked on the rim of a carriage wheel, this point, as the wheel rolls along the road, will trace a curve in the air from one part of the road to another, which is called a cycloid, and to which the law of ...

Rest and motion are not opposites, for rest may be considered as infinitely minute motion; the ellipse and the parabola are not qualitatively different, for the laws which hold for the one may be applied to the other. Likeness is vanishing unlikeness, passivity arrested activity, evil a lesser good, confused ideas simply less distinct ...

And yet—notwithstanding the repugnancy of the doctrine, in its unqualified sense, to ...

... 1844, swarms of locusts visited the island of Madeira. They were in countless numbers, as thick as the flakes of snow in the heaviest snowstorm, and extended upward as far as could be seen with a telescope. During two or three days they slowly careered round and round in an immense ellipse, at least five or six miles in diameter, and at night alighted on the taller trees, which were completely coated with them. They then disappeared over the sea, as suddenly as they had appeared, and have not since visited the island. Now, in parts of Natal it is believed by some farmers, though ...

From Crossen, whither Friedrich is now driving, to the Jablunka Pass, which issues upon Hungary, is above 250 miles; the AXIS, therefore, or longest diameter, of our Ellipse we may call 230 English miles;—its shortest or conjugate diameter, from Friedland in Bohemia (Wallenstein's old Friedland), by Breslau across the Oder to the Polish Frontier, is about 100.

As seen from the print, the sum total of all displacements represents a very regular ellipse, and some of the lines representing the earth's motion can be traced along the whole circumference. The result of observation indicates that our heaviest shocks are in the direction south-southeast to north-northwest. In that respect the records of the three heaviest earthquakes agree entirely. ...

Thus, if we correct the observed ...

The outline of the buttresses being that of a semi-ellipse, they look like turrets carried up the entire face of the wall.

But it was a graft on the old Roman arch,—in the shape of an ellipse rather than a circle.

We have found out no new principles which were not equally known ...

... consent of their hearts to their actions, entitle themselves to moral praise or moral censure. The question is, whether by the mere co-existence of these opposite qualifies in the monad man, he has proved that such qualities can coexist.

... grave doubts, Carnes, although I can make a pretty shrewd guess. As to the reason for the unnatural lengthening of the day, the explanation is simplicity itself. As you doubtless know, the earth revolves daily on its axis. At the same time, it is moving in a great ellipse about the sun, an ellipse which it takes it a year to cover. If the axis of rotation of the earth were at right angles to the plane of its orbit; in other words, if the earth's equator lay in the plane of the earth's movement about the sun, each day would be of the same length and there would ...

It will immediately be objected, that our idea of a surface is as independent of this method of forming a surface, as our idea of an ellipse is of that of a cone; that the idea of a right line is no more precise than that of a plain surface; that a right line may flow irregularly, and by that means form a figure quite different from a plane; and that therefore we must ...

Could we realise all the links in this chain, by placing the objects in their actual order as a VISIBLE series, the reasoning would be a succession of perceptions.

From the point of view of the impression they make on our eye these geometrical figures may assume very varied shapes. By perspective the cube may be transformed into a pyramid or a square, the circle into an ellipse or a straight line.

The movements are rectilinear, but two rectilinear vibrations of equal amplitude acting at right angles to each other generate a circle if they alternate precisely, an ellipse if the alternations are less regular or the amplitudes unequal. A cyclic vibration may also be obtained from a pendulum free to swing in a rotary path.
