"Conic" Quotes from Famous Books
 ... and figure lenses for every step of the theory, to keep myself in the right track; as mere theorizing is apt to lead one very much astray, unless it be checked by constant experiment. For this particular subject, lenses must be ground firstly to spherical, and then to curves of conic sections, so as to eliminate spherical aberration from each lens; so that it will be observed that this subject is not without ...

... 1764, and to this, in the second edition of 1771, was added the Treatise on Spherical Tangencies, by Fermat, which has since been reprinted in the Appendix to the Ladies' Diary for 1840. In 1767 appeared Emerson's Treatise on Conic Sections; a work which, notwithstanding its manifest defects, contributed not a little to aid the student in his approaches to the higher geometry, but whose publication would probably have been rendered unnecessary, had Dr. Simson so far loosened himself from the ...

... decision I remained at Vauclaire another week, a very different man to the lounger it had seen, strenuous, converted, humble, making plans of this and of that, of the detail, and of the whole, drawing, multiplying, dividing, adding, conic sections and the rule-of-three, totting up the period of building, which came out at a little over twelve years, estimating the quantities of material, weight and bulk, my nights full of nightmare as to the sort, deciding as to the size and structure ...

... was somewhat elective, but her advice to me was, not to omit anything because I did not like it. I had a natural distaste for mathematics, and my recollections of my struggles with trigonometry and conic sections are not altogether those of a conquering heroine. But my teacher told me that my mind had need of just that exact sort of discipline, and ...

... proportion to one another (such as the shock of some solid body, or even the accumulating effect of the resistance of the medium in which astronomers have been led to surmise that the motions of the heavenly bodies take place), the elliptical motion might be changed into a motion in some other conic section; and the complex law, that the planetary motions take place in ellipses, would be deprived of its universality, though the discovery would not at all detract from the universality of the simpler laws into which that complex ...

... warrantable admirers found that she insisted on accepting them as endowed with all the Christian virtues. Just as some amateurs of music are incapable of conceiving that there breathes a man who has no joy in popular concerts (we shall have popular conic sections next), so Mrs. St John Deloraine persevered in crediting all she met with a passion for virtue. Their speech might bewray them as worldlings of the world, but she insisted on interpreting their talk as a kind of harmless levity, as a mere cynical mask assumed ...

... original state of our goodly college at its founding. Plans and specifications showing its extent and magnificence have been continually before the board for the last month; and in such repute have been a smashed door-sill or an old arch, that freshmen have now abandoned conic sections for crowbars, and instead of the "Principia" have taken up the pickaxe. You know, my dear fellow, with what enthusiasm I enter into any scheme for the aggrandizement of our Alma Mater, so I need ...

FDB, approaching the point H as the sun advances towards noon, and receding from it afterwards. (The curve is a conic section—an hyperbola in these regions.) At the moment when it crosses the arc AB, mark the point A; AP is then the direction of the sun, and, as AH is horizontal, the angle PAH is the altitude of the sun. In the afternoon mark the point B ...

... who wrote a treatise on Conic sections at the age of 16, and had composed most of his mathematical works and made his chief experiments in science by the age of 26, was in constant suffering, by disease, from his 18th year until his death, in 1662, at the age stated in the text. Expectation of an early death caused him to ...

... only pupil she had in that science, in heraldry, which she loved. It is far more pleasant to be describing a shield and settling questions in the queer old language of this queer old science, than in solving and propounding problems in trigonometry and conic sections. And then—how if your pupil begins to talk round the subject and to wander into other things? You cannot very well talk round a branch of mathematics, but heraldry is a subject surrounded by fields, meadows, and ...

... all our sensibilities, pleasures, affections, aspirations, capacities, it is thought on that ground to have a special nobility and greatness, and a special power of evoking in the student the feelings themselves.

She took everything severe that she could get a chance at, in the course or out of it,—surveying, navigation, mechanics, mathematical astronomy, and conic sections, as well as the ordinary course in mathematics; the calculus she had worked through at sixteen under a very able and exact teacher, and took her diploma from W.H. Wells, a master who allowed nothing to go slipshod. She was absorbed in studies of this kind, ...

Greek and Latin, Aristotle's logic and classical versification, quadratic equations, conic sections, the differential calculus, are very good things, and we are well aware that it is by excellence in them that the highest honours in these seminaries of learning can alone be attained. They are ...

... Mateo had been suppressed by a government which was the sworn enemy of every form of enlightenment. The new seminary, however, continued the work of the old with little change: While there Jos carried his mathematical studies through higher algebra, conic sections, trigonometry, and surveying, and continued Latin, French, English, and Greek. If we may judge from later results, a course in rhetoric and poetics must have been of greatest benefit ...

She saw her, with mute wonder, blooming out before her very eyes, from a stout, stocky, frowzy child, with coarse red cheeks and knuckles like a bootblack, into a tall, slender girl, whose oval face was as regular as a conic section, and whose movements were as swift, strong, and graceful, when she forgot herself, as those of a race-horse. There were still the ties of habit and romance between them. Azalea, whose brother was a train-boy ...

... anything that we can call or think to be a neuter or medium between equal and unequal. Besides, if there are superficies neither equal nor unequal, what hinders but there may be also circles neither equal nor unequal? For indeed these superficies of conic sections are circles. And if circles, why may not also their diameters be neither equal nor unequal? And if so, why not also angles, triangles, parallelograms, parallelopipeds, and bodies? For if the longitudes are neither equal nor unequal to one another, so will the weight, percussion, ...

At any rate, I cannot help referring this paradise of twisted spines to some idea floating in her head connected with her friend whom Nature has warped in the moulding.—That is nothing to another ...

Mercator had published the map of the world (1569) which has ever since born his name, and the Gregorian calendar had been introduced (1572). The barometer, thermometer, air-pump, pendulum clock, and the telescope ...

... flight in convex parabolic curves, wherein resistance is overcome by a minimum of force; and elastic surfaces obey the converse of that law in opposing certain external influences. It is a property of conic sections that a straight line, centred in the apex, and caused to circumscribe the surface of the cone, will apply itself continuously to all consecutive parabolic curves. Hence curves similar to the flight of projectiles, and to those formed by the flection of elastic surfaces, may be described ...
