Philosophy and Fun of Algebra

Printed: 9.99 $eBook: 4.99 $

My Dear Children,
A young monkey named Genius picked a green walnut, and bit, through a bitter rind, down into a hard shell. He then threw the walnut away, saying:

“How stupid people are! They told me walnuts are good to eat.” His grandmother, whose name was Wisdom, picked up the walnut—peeled off the rind with her fingers, cracked the shell, and shared the kernel with her grandson, saying: “Those get on best in life who do not trust to first impressions.” In some old books the story is told differently; the grandmother is called Mrs Cunning-Greed, and she eats all the kernel herself. Fables about the Cunning-Greed family are written to make children laugh. It is good for you to laugh; it makes you grow strong, and gives you the habit of understanding jokes and not being made miserable by them. But take care not to believe such fables; because, if you believe them, they give you bad dreams.

MARY EVEREST BOOLE.

"Why did the apple fall out of the tree? Does everything fall? What makes things fall? Can anything stop things from falling? Are the sun, moon, and stars falling? Why don't they ever hit the ground?
So many questions. Newton spent many years answering these questions by thinking and doing experiments. He made up the law of gravity. According to this law everything pulled everything else to itself by a force called gravity. How strong that force is depends on how heavy the things are and how close together..
This book telling this excellent biographic story very simple, teaching and amazingly.."

Lord Kelvin writing-in 1893, in his prefaceto the English edition of Hertz's Researches on Electric Waves, says" many workers and many thinkers have helped to build up the nineteenth century school of plenum, one ether for light, heat, electricity, magnetism; and the German and English volumes containing Hertz's electrical papers, given to th

The Pythagorean Triangle

The Pythagorean Triangle

Printed: 14.99 $

The three fixed lights, or windows, subsequently exchanged for our lesser luminaries, were explained one hundred and fifty years ago to signify " the three Persons, Father, Son, Holy Ghost ; " and were used to find out the meridian, " when the sun leaves the south, and breaks in at the west window of the Lodge." While the " mossy bed," the ancient signs of disgust and recognition, as well as the primitive name of a Master Mason, are equally obscure at the present day; having been swept away, along with the original method of characterising chemical bodies by symbols, as being no longer necessary to the system.

Perpetual Motion

Printed: 14.99 $eBook: 3.99 $

The author has no apology to offer for the production of this book. He has spent his life in environments that have brought him into constant contact with mechanics, artisans and laborers as well as professional men, engineers, chemists and technical experts of various types. He knows a great many men—young men, for the most part—are constantly working on the old, old problem of Perpetual Motion; that much money, and much time are being spent in search of a solution for that problem which all scientific and technical men tell us is impossible of solution.

Plane Geometry

Plane Geometry

Printed: 16.99 $eBook: 4.99 $

It is intended to have the first sixteen pages of this book simply read in the class, with such running comment and discussion as may be useful to help the beginner catch the spirit of the subject-matter, and not leave him to the mere letter of dry definitions. In like manner, the definitions at the beginning of each Book should be read and discussed in the recitation room.

There is a decided advantage in having the de_nitions for each Book in a single group so that they can be included in one survey and discussion. For a similar reason the theorems of limits are considered together. The subject of limits is exceedingly interesting in itself, and it was thought best to include in the theory of limits in the second Book every principle required for Plane and Solid Geometry.
