In 1816 London, widow Catherine St. Day hires Lucy Muchelney to translate a French astronomy text and thus finish her husband's scientific legacy, and they unexpectedly find themselves falling in love.

An accessible exposition of gravitation theory and celestial mechanics, this classic, oft-cited work was written by a distinguished Soviet astronomer. It explains with exceptional clarity the methods used by physicists in studying celestial phenomena. A historical introduction explains the Ptolemaic view of planetary motion and its displacement by the studies of Copernicus, Kepler, and Newton. Succeeding chapters examine the making of celestial observations...

First published in Latin in 1687, "Mathematical Principles of Natural Philosophy", commonly referred to as "The Principia", is the groundbreaking work of science and mathematics by Isaac Newton. Consisting of three books, "The Principia" was updated twice by Newton during his lifetime, with new editions published in 1713 and 1726, as he further refined and expanded his ideas. "The Principia" introduced Newton's laws of motion and his law of universal...

Will help you appreciate and understand the significance of Isaac Newton's masterpiece-what many regard as the greatest scientific contribution of all time. Despite its dazzling reputation, Isaac Newton's “Philosophiae Naturalis Principia Mathematica”, or simply “The Principia”, remains a mystery for many people. Few of even the most intellectually curious readers, including professional scientists and mathematicians, have actually looked...

"The science of heavenly bodies - astronomy - is one of the oldest. Even in ancient times, people looked at the sky and tried to find answers to many not only philosophical, but also practical questions. The stars and planets helped to navigate the terrain and determine the time. Thanks to the knowledge received from the heavens, it became possible to predict the frequency of solar and lunar eclipses and draw up calendars, and sea navigation began...

Presents experiments for kids and adults, each designed to show how mechanical science and astrophysics work from the inside out. Kids learn to make scientific observations, ask questions, identify and classify and find answers to their questions, all while investigating space.
