Induction of Electric Currents. 6. About twenty-six feet of copper wire one twentieth of an inch in diameter were wound round a cylinder of wood as a helix, the different spires of which were prevented from touching by a thin interposed twine. This helix was covered with calico, and then a second wire applied in the same manner. In this way twelve helices were superposed, each containing an average... more...

As will be seen later on, Pygmalion needs, not a preface, but a sequel, which I have supplied in its due place. The English have no respect for their language, and will not teach their children to speak it. They spell it so abominably that no man can teach himself what it sounds like. It is impossible for an Englishman to open his mouth without making some other Englishman hate or despise him. German... more...

hen you are out in a clear night in summer, the sky looks very warm and friendly. The moon is a big pleasant place where it may not be so humid as where you are, and it is lighter than anything you've ever seen. That's the way it is in summer. You never think about space being "out there". It's all one big wonderful thing, and you can never really fall off, or have anything bad... more...

In an inventive tour de force that seldom, if ever, has been equalled for its brilliance and far-reaching consequences, James Watt radically altered the steam engine not only by adding a separate condenser but by creating a whole new family of linkages. His approach was largely empirical, as we use the word today. This study suggests that, despite the glamor of today's sophisticated methods of... more...

LAST CHAPTER 1 "There is a God after all." That was the immense conviction that faced him as he heard, slowly, softly, the leaves, the twigs, settle themselves after that first horrid crash which the clumsy body had made. Olva Dune stood for an instant straight and stiff, his arms heavily at his side, and the dank, misty wood slipped back once more into silence. There was about him now the most... more...

INTRODUCTORY.—NUMBER ONE. I would that it were possible so to tell a story that a reader should beforehand know every detail of it up to a certain point, or be so circumstanced that he might be supposed to know. In telling the little novelettes of our life, we commence our narrations with the presumption that these details are borne in mind, and though they be all forgotten, the stories come out... more...

“‘St. Ronan's Well’ is not so much my favourite as certain of its predecessors,” Lady Louisa Stuart wrote to Scott on March 26, 1824. “Yet still I see the author's hand in it, et c'est tout dire. Meg Dods, the meeting” (vol. i. chap. ix.), “and the last scene between Clara and her brother, are marked with the true stamp, not to be matched or mistaken. Is the Siege of... more...

THE DOLLIVER ROMANCE. In "The Dolliver Romance," only three chapters of which the author lived to complete, we get an intimation as to what would have been the ultimate form given to that romance founded on the Elixir of Life, for which "Septimius Felton" was the preliminary study. Having abandoned this study, and apparently forsaken the whole scheme in 1862, Hawthorne was moved to... more...

PREFACE A collection of about 2000 questions asked by children forms the foundation on which this book is built. Rather than decide what it is that children ought to know, or what knowledge could best be fitted into some educational theory, an attempt was made to find out what children want to know. The obvious way to discover this was to let them ask questions. The questions collected were asked by... more...
