. . .I will tell you how we have laid out our time for this term. Our human consciousness may be said to begin at half-past five o'clock in the morning. The hour from six to seven is appointed for mathematics, namely, geometry and trigonometry.
"Our curriculum, sir," corrected the school-master, "embraces geography, arithmetic, trigonometry " "That'll do," interrupted the father. "That'll do. Load him up well with triggernometry. He's the only poor shot in the family." "Now, my dear girl," said Bluebeard, "remember you can go anywhere in the house but the pantry. That is locked up, and the key will be placed under the mat.
Then, still others divide and subdivide, and science becomes the sciences, and mathematics becomes arithmetic, and algebra, and geometry, and trigonometry, and calculus, and astronomy. Here mathematics and science seem to merge. And, in time, history and geography come together, and sometimes strive for precedence.
As at West Point, the mathematics is the stumbling block of the new man at Annapolis. In the first term algebra, logarithms and geometry had to be finished, for in the second term trigonometry was the subject in mathematics. Shortly before eight in the morning the bugle call sounded for the first period of recitation. The midshipmen fell in by classes in front of Bancroft Hall.
The generalized view of angles and their measurement is treated in the article TRIGONOMETRY. A solid angle is definable as the space contained by three or more planes intersecting in a common point; it is familiarly represented by a corner. The angle between two planes is termed dihedral, between three trihedral, between any number more than three polyhedral.
The course 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 I think she was right.
The professors seemed to him living wonders. "By Jove!" he said, "the professor of mathematics is a marvel. You ought to see him explaining trigonometry on the blackboard. You can't understand a word of it." He hardly knew which of his studies he liked best. "Physics," he said, "is a wonderful study. I got five per cent in it. But, by Jove! I had to work for it.
No one gets into mischief that has pleasant things to think of and to do when alone; and I know, for my part, that trigonometry is "
Our common-school system now rejects sewing from the education of girls, which very properly used to occupy many hours daily in school a generation ago. The daughters of laborers and artisans are put through algebra, geometry, trigonometry, and the higher mathematics, to the entire neglect of that learning which belongs distinctively to woman.
Point to a divine portrait of Titian, to an angelic head of Guido, close by they see and heed it not. What are the 'looks commercing with the skies, the soul speaking in the face, to them? It asks another and an inner sense to comprehend them; but for the trigonometry of painting, nature has constituted them indifferently well.
