... subject. Thus shut up to his own resources, the masterful little fellow, about his eighth year, drawing charcoal diagrams on the floor, made perceptible progress in working out geometry for himself. At sixteen he produced a treatise on conic sections that excited the wonder and incredulity of Descartes. Later, he experimented in barometry, and pursued investigations in mechanics. Later still, he made what seemed to be approaches ...

... health after my husband's death, and chiefly occupied with my children, especially with the one I was nursing; but as I did not go into society, I rose early, and, having plenty of time, I resumed my mathematical studies. By this time I had studied plane and spherical trigonometry, conic sections, and Fergusson's "Astronomy." I think it was immediately after my return to Scotland that I attempted to read Newton's "Principia." I found it extremely difficult, and certainly did not understand ...

... 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 ...

... by the color of the peridium and the conic columella. According to Mr. Lister, Rostafinski was not specially careful in labelling his material, different forms having been included under this specific name. Nevertheless, the description is well drawn, and excludes L. physaroides completely. At all events our American specimens ...

... High Dutch. I have been several times to different parts of the East Indies, and on more than one voyage have kept a reckoning out and home, assisted in taking lunar observations and those for determining the time and variation of the compass, and without knowing any more of algebra, fluxions, or conic sections, than a dog knows ...

... of all the members of the colony, including Master Jup and Top, the four cannon were successively tried. They were charged with pyroxile, taking into consideration its explosive power, which, as has been said, is four times that of ordinary powder: the projectile to be fired was cylindro-conic. ...

... friends, who had had breakfast with us and again made themselves useful, we started for the twins. To the south of them was a range of some length; of this the twins formed a part. I called it Seymour's Range, and a conic hill at its western end Mount Ormerod. We passed the twins in eleven miles, and found some water in the creek near a peculiar red sandstone hill, Mount Quin; the general course of the creek was south ...

... appears perfectly barren. Ridges of hills run toward the sea; between which ridges are deep valleys, terminating at mountains or hills that ran across, and are higher than the former. Those that run toward the sea, are marked by impressions on their sides, which make them appear as a succession of conic hills, with their tops very rugged. The higher ones that run across, are more ...

... coast ranges; and seemed to be also connected with those stretching towards Bindango, and separating the basin of the upper Balonne from this interior country. A hill similar to that on which I stood, but of less height, lay on the interior side of it, having a remarkable conic summit clear of bushes. The valley at the base of these two hills contained a fine crop of ANTHISTIRIA; and there was also a chain of ponds, where natives had been encamped not long before, but in which no water ...

... swimmingly between the Professor of Mathematics and the Junior Class at Polyp University. In every man of the seventy the sage saw the logarithm of a possible La Place, of a Sturm, or of a Newton. It was a delightful task for him to lead them through the pleasant valleys of conic sections, and beside the still waters of the integral calculus. Figuratively speaking, his problem was not a hard one. He had only to manipulate, and eliminate, and to raise to a higher power, and the triumphant result of examination ...

... solids are the most capacious. Hippocrates treated of the duplication of the cube, and wrote elements of geometry, and knew that the area of a circle was equal to a triangle whose base is equal to its circumference and altitude equal to its radius. The disciples of Plato invented conic sections, and ...

... that satisfaction we receive from the sciences, yet I doubt, if it be alone sufficient to give us any considerable enjoyment. The truth we discover must also be of some importance. It is easy to multiply algebraical problems to infinity, nor is there any end in the discovery of the proportions of conic sections; though few mathematicians take any pleasure in these researches, but turn their thoughts to what is more useful and important. Now the question is, after what manner this utility and importance operate upon us? The difficulty ...

... with perfect fidelity the movements of a planet in its revolution around the sun belongs to that well-known group of curves which mathematicians describe as the conic sections. The particular form of conic section which denotes the orbit of a planet is known by the name of the ellipse: it is spoken of somewhat less accurately as an oval. The ellipse is a curve which can be readily constructed. There is no simpler method of doing ...

... unities, and those lines which by common consent are understood to be exponential of certain phases of our own existence. No well-organized intellect can fail to perceive that a sublime and immortal Truth underlies these speculations. Undoubtedly, in the straight line, in the conic sections, in the innumerable composite curves of the mathematician, lie the germs of all these symbolic expressions. But the artist, whose lines of Beauty vary continually with the emotions which produce them, who feels in his own human heart the irresistible ...

... stands for all our total past. Much of this past, indeed most of it, only endures as unconscious Memory, but it is always capable of coming to the apex of the cone, i.e., coming into consciousness. So we may say that there are different planes of Memory, conic sections, if we keep up the original metaphor, and the largest of these contains all our past. This may be well described as "the plane of dream."[Footnote: See Matter and Memory, p. 222 (Fr. p. 186) and the paper L'Effort intellectuel, Revue philosophique, Jan., ...

Exactly the same combinations never conic up, new ones are continually being presented, and in every case he must decide for himself what is best. In view of all the circumstances, he makes a quick mental estimate of the chances and acts accordingly. Sometimes for-time will ...

... philosophy is not adapted to the great mass of mankind; it soars too highly above the vulgar; it speaks a language they are unable to comprehend. To propose philosophy to them, would be just as weak as to propose the study of conic sections to peasants or fish-women. Among philosophers themselves, I know of no one besides Maximus Tyrius who has treated of this subject. The following is the substance of his ideas upon it:—The designs of God exist from all eternity. If the object prayed for be conformable to his immutable ...

... instruction—the 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 lawns, so to speak, all covered with beautiful ...

... tried it by addition, simple and otherwise, and he tried it by mixed examples in vulgar fractions. But it was all of no use. Then he tried to do the sum by algebra, by simple and by quadratic equations, by trigonometry, by logarithms, and by conic sections. But it would not do. He got an answer every time, it is true, but it was always a different one, and he could not feel sure ...
