This is the story of talking at a distance, of sending messages through space. It is the story of great men—Morse, Thomson, Bell, Marconi, and others—and how, with the aid of men like Field, Vail, Catty, Pupin, the scientist, and others in both the technical and commercial fields, they succeeded in flashing both messages and speech around the world, with wires and without wires. It is the story of how the thought of the world has been linked together by those modern wonders of science and of industry—the telegraph, the submarine cable, the telephone, the wireless telegraph, and, most ...

The main purpose of this book is to show the historical relations of the new principle to the old philosophical problems and to the classical theories of space and time. - Summary by Adapted from the Preface

A brief history of the rise and reign of Duke William of Normandy, King of England.

The universe is watching you. And it's been running tests. Why does observing a particle change how it behaves? Why are physical constants tuned to impossible precision? Why do we see no aliens despite billions of planets where life could exist? Why does the future affect the past in quantum experiments? These aren't mysteries. They're experimental protocols.

It would be an interesting thing to make a careful study once a year, towards the end of the summer, of the habits and customs of thunder and lightning. Perhaps in this way we should succeed one day in determining the still mysterious nature of these elusive forces. I, for my part, have been engaged upon the task for many years past. It has produced a big accumulation of records, and in this volume I can find room but for a résumé of them, as varied as possible. - Summary by Camille Flammarion

This book was curated by the State Federation of Pennsylvania Women for tourists' use on a journey to Pennsylvania. Each of Pennsylvania's 67 counties has its own chapter, discussing beautiful art and buildings that may be found there (or, in lieu of art, pioneer history). These chapters were each written by a knowledgeable person from that county. While details are often sparse, the guide is an excellent starting point for individuals who wish to learn more about local history of Pennsylvania. Note: While the book was compiled in 1917, the first world war prevented its publication until 1924....

Это аудиокнига о компании, которая перевернула представления о том, какой должна быть космонавтика. О людях, которые, не имея права на ошибку, сделали невозможное. И о человеке, чьи идеи одновременно восхищают и раздражают, но неизменно двигают мир вперед. Двадцать лет назад SpaceX была маленьким стартапом, неспособным запустить даже одну ракету. Сегодня это корпорация, ежегодно отправляющая в космос более сотни миссий, мировой лидер и главный ускоритель технологической революции в отрасли. Как это стало возможным?

What was before the universe? If space is expanding, what is it expanding into? Where did all the matter come from to form planets, stars, and oceans? What is nothing? And if none of these questions can be answered, why do we keep asking them? The Pointless Book asks the biggest questions human beings have ever conceived. The kind of questions that keep you awake at three in the morning. The kind that feel like they should have answers but never do. This book tries to answer them. It reaches for quantum physics, simulation theory, cosmology, philosophy, and religion.
