Ever been confused by basic physics and intimidated by the mere thought of Einstein's relativity theories? If so, yet curiosity still beckons, this book is for you The reward? The colorful history of the elusive notion of motion and unique insights into the fundamental physics behind it all - including relativity. The physics of motion is so fundamental to science and the technological age in which we live that four of the most illustrious names in the annals of science owe their towering reputations, in large part, to their milestone work on the physics of motion. This book relates the stories of Johannes Kepler, Galileo Galilei, Isaac Newton, and Albert Einstein as they each stalked the elusive notion of motion. Following in their footsteps, both the layperson with no formal background in mathematics or physics and the practicing engineer/scientist will better understand those physical principles which eluded the best minds for centuries. As Aristotle observed over two thousand years ago, in order to know the natural world, one must first understand motion. Alan Kubitz lives in the heart of California's silicon valley where he spent many years as an electrical engineer designing computer peripheral devices. Throughout his engineering career and subsequent retirement, he has been deeply interested in the history of science, with an emphasis on the fifteenth through the nineteenth centuries. His particular interest is the physics of motion and the pioneering scientists (natural philosophers) such as Galileo and Newton who bequeathed to us the intellectual crown jewels which comprise the foundation of modern physics. Mr. Kubitz has accumulated a substantial reference library on these subjects and enjoys writing about them. Other interests include music, book collecting and, with his wife, their four grandchildren. He holds a Bachelor of Science degree in electrical engineering from Stanford University and a Master of Science degree in electrical engineering from the University of California, Santa Barbara.

Mechanics, the science of moving bodies and their interactions, is among the finest accomplishments of western civilization. This is the story of development, from the ground-breaking attempts of the Greeks, through the brilliant abstractions of medieval logicians, to the breathtaking achievements of Galileo, Huygens, and Newton, to the dazzling virtuosity of Maxwell and Einstein. Crowe's presentation allows the reader to appreciate this story from the inside, following the thoughts of the original authors in their own words. Ample commentary places these scientific giants in their context and helps modern readers understand the unfamiliar modes of expression of earlier times. In the course of telling the story, this book also provides a practical introduction to mechanics, with sample computations and problems in both classical physics and relativistic kinematics.

This book aims to introduce to the reader the main thread of development from Newton's laws to Einstein's theory of relativity. Limited by its scope and avoiding as much as possible the use of mathematical apparatus, the authors try to clarify the most fundamental ideas and concepts. Both authors hold a deep reverence for Galileo and Einstein, and this book is dedicated to these two great scientists.

In this ebook, you’re going to learn and take inspiration from the lives and works of Isaac Newton, Galileo Galilei, Albert Einstein and Stephen Hawking. Learn about their childhood, and the events that inspired them to search for scientific answers. Go ahead and grab a copy of this ebook today.

As to the first, the last discoveries of Saturn to be tricorporeall, and of the mutations of Figure in Venus, like to those that are seen in the Moon, together with the Consequents depending thereupon, have not so much occasioned the demur, as the investigation of the times of the Conversions of each of the Four Medicean Planets about Jupiter, which I lighted upon in April the year past, 1611, at my being in Rome; where, in the end, I assertained my selfe, that the first and neerest to Jupiter, moved about 8 gr. & 29 m. of its Sphere in an houre, makeing its whole revolution in one naturall day, and 18 hours, and almost an halfe. The second moves in its Orbe 14 gr. 13 min. or very neer, in an hour, and its compleat conversion is consummate in 3 dayes, 13 hours, and one third, or thereabouts. The third passeth in an hour, 2 gr. 6 min. little more or less of its Circle, and measures it all in 7 dayes, 4 hours, or very neer. The fourth, and more remote than the rest, goes in one houre, 0 gr 54 min. and almost an halfe of its Sphere, and finisheth it all in 16 dayes, and very neer 18 hours. But because the excessive velocity of their returns or restitutions, requires a most scrupulous precisenesse to calculate their places, in times past and future, especially if the time be for many Moneths or Years; I am therefore forced, with other Observations, and more exact than the former, and in times more remote from one another, to correct the Tables of such Motions, and limit them even to the shortest moment: for such exactnesse my first Observations suffice not; not only in regard of the short intervals of Time, but because I had not as then found out a way to measure the distances between the said Planets by any Instrument: I Observed such Intervals with simple relation to the Diameter of the Body of Jupiter; taken, as we have said, by the eye, the which, though they admit not errors of above a Minute, yet they suffice not for the determination of the exact greatness of the Spheres of those Stars. But now that I have hit upon a way of taking such measures without failing, scarce in a very few Seconds, I will continue the observation to the very occultation of JUPITER, which shall serve to bring us to the perfect knowledge of the Motions, and Magnitudes of the Orbes of the said Planets, together also with some other consequences thence arising. I adde to these things the observation of some obscure Spots, which are discovered in the Solar Body, which changing, position in that, propounds to our consideration a great argument either that the Sun revolves in it selfe, or that perhaps other Starrs, in like manner as Venus and Mercury, revolve about it, invisible in other times, by reason of their small digressions, lesse than that of Mercury, and only visible when they interpose between the Sun and our eye, or else hint the truth of both this and that; the certainty of which things ought not to be contemned, nor omitted.
