JA la, 71,01 ca. ,125 Aagfffff .1 ,VA fwnuy CPhysic-al Fitness Physical fitness is something everyone can and should enjoy. The only way to have a sound constitution is to practice the exercises of health laws. You probably have , heard of these laws but have, no doubt, forgotten them. They concern every vital organ Q of- the human machine. ! An athlete exercises these natural laws, and as a result he excels in some par- ' ticular sport, an honor which only a healthy and vigorous body can attain. Muscular i development is important to the athlete, but it is equally significant to you. The illus- i tration points out some of the mainsprings in a great co-operative organization. The stomach is the seat of the digestive tract. The lungs purify the blood with the life- 1 ' giving supply of oxygen. The muscles are the chief places where the energy is used. jg ' The nerves are the message bearers of the great engine. The senses of sigh't, smell, i 1 taste, feeling, and hearing aid in judgment and reasoning. You have these faculties il ' combined. Are you going to neglect these organs and faculties, or are you going to i develop them? Life tasks demand physical fitness. Keep yourself fit by exercising xi regularly, by securing fresh air from the out of doors, by eating plenty of wholesome ig i food, by securing sufficient sleep, and by regular habits and by clean living. 1 1 V 1 i I IIki!I!!iilgiilllilliiliilliliiiliiiililillliiliillkilliilllgigll!WEEEiiiilligilgliillgiiiillilgl!5iiHIiEl5?il15ili3iF:iIlSliiHlI?I I N 1 Page One Hundred Two

In summer there are only three or four hours of darkness and in winter only .three or four hours of daylight. The radiance of the sun varies in intensity de- pending upon the moisture or clearness of the atmosphere, presence of clouds and other factors. One day it will be as red as orange, and so dull in radiance that it can be looked upon with the naked eye. At another time it glows like a live flame. There are, also, days when it is a bluish-white color, like the moon. The most curious thing about the sun is its motion. It does not once hide itself from May 13th to July 29th, while from November 21st to January 21st it is seen but a very few hours. At the North pole every direction is due south. Therefore it is evident that the sun moves round us in a gigantic circle roughly par- allel to the horizon. It gradually ascends in a slow spiral until it grazes the horizon. Next it is cut in half, then only the upper part shows. This disappears, and after a period of twi- light the long Arctic night sets in. Although the sky is no darker than ours at twilight, the long night is relieved by a huge electric light which is kept burning during this season. The beautiful Aurora Borealis, too, lights up the winter sky with its streamers of light. The path of light usually forms a fiery arch across the northern sky, with its streams of light ascending from a line of haze or cloud, sometimes to a point almost directly over- head. Its rays are transient and constantly in motion, varying in color from a greenish hue or a pale yellow to a deep, blood red, and its shapes are infinite in num- ber. These auroras are caused by the passage of electricity through the rarified upper atmosphere. A similar effect is produced by passing electrical currents through rari- fied air or gases. During the appearance of an aurora the magnetic needle is subject to disturbance, showing a close connection between the aurora and magnetism. The aurora australis is the corresponding light seen in the southern hemisphere. The return of spring is just the reverse of that of winter-Hrst, the twilight, then a faint rim of light crawling round the edge of the land- scape, making complete circles, until finally it is day. When this summer sun does smile upon the Northland, all life quickly responds. Plants sometimes grow three inches in a day. Vege- tables and fruits mature in six weeks. Flowers do not close in sleep and birds fly all night upon their way. Directions in these Northern coun- tries are quite as confusing as the time of day. To see the sun in the north at midnight, watch it ascend Without having dipped out of sight, and t circle about in the heavens through the day, is bewildering to one accustomed to see it rise in the east and set in the west. Note the two illustrations. In the Summer the sun is continually rising, never ' k' lehind the earth while in winter it rises above the horizon only as high as sin ing J L I , , the lowest point during the summer. then sinking out of sight behind the earth.

'25 We have formed an organization which we call The Society for the Prevention of cruelty to Mathematics . We are doing this as a means of preserving the right attitude toward this subject. A professor reports in a recent educational journal that he made a study of the views hold by high school pupils concerning their school subjects. He says they con- sider English the easiest and most valuable, while mathematics is the hardest and of least value. We do not believe that Central Junior High School pupils would agree with him. One authority says that it was an epoch in the history of thought when man learned to think in symbols, to deal with types, instead of individuals. Mathematics is a universal language, in the sense that most of its important symbols are interna- tional, like those of music. The great Leibnetz thought it might be possible to bring the entire universe of nature and of the mind under the sway of mathematical method. He declared: I dare say that this is the last effort of the human mind and when this project shall have been carried out all that men will have to do will be to be happy, since they will have an in- strument that will have served to exalt the intellect not less than the telescope serves to perfect their vision. The name Algebra fAl-Jebrj was derived from the title of the Arabic word by Al-Khuevarizmi about the science that relates to the reduction of equations to in- tegral form and to the transposition of terms. The title appeared thereafter in various forms, but the abbreviation Algebra was finally adopted. The exact limitations of Algebra are not generally agreed upon by mathematicians, and various definitions have been proposed for the science. Perhaps the most satis- factory definition, especially as it brings out the distinction between Algebra and Arith- metic, is that of Comte: Algebra is the calculus of functions, and arithmetic is the calculation of values . Algebra is a branch of mathematics that materially simplifies the solution of arithmetical problems, especially through the use of equations. It also forms the introduction to all of the higher branches of mathematical science except pure geometry. Ahmes was an Egyptian scribe who lived before 1700 B. C. He wrote 'tDirections for finding all dark things . This was not original with him. It was copied from an older treatise, dating from about 2500 B. C. It is important as one of the earliest satisfactory accounts of ancient Egyptian mathematics. Thales, the earliest of Greek philosophers, as the founder of the Ionic school, Hourished in the first half of the sixth century, B. C. He was reckoned one of the Seven Wise Men. He was famed for his practical and political wisdom. Geometry started as an art among the Egyptians, as a necessary way of meas- uring the earth. The overflow of the Nile made careful measurements necessary, as all the landmarks were covered or washed away. The Egyptians made their measurements by angles. These were made by the three, four, five right triangle method. They used this triangle in building their temples, which always faced the east. They kept all their knowledge secret. The Greeks made Geometry into a science. The school ot' Pythagoras was founded on secrecy and was finally closed by the Govern- ment as it became too powerful. Mathematics is no less powerful today, but our teachers are doing all they can to pri-vs-nt its being a secret. If it were not for mathematics we should not have our homes, the electricity that lights them, nor automobiles, aeroplanes, radio, steamships or any of the modern things that make us happy. Not a wheel would turn, not a bulb would fit in its socket, not a record would reproduce its marvelous music and never would a crystal set tune in.
