On The Shoulders Of Giants Stephen Hawking Ebook

In On the Shoulders of Giants, Stephen Hawking brings together the greatest works by Copernicus, Galileo, Kepler, Newton and Einstein, showing how their. World-renowned physicist and bestselling author Stephen Hawking presents a revolutionary look at the momentous discoveries that changed our perception of. download The Illustrated On the Shoulders of Giants: The Great Works of Physics and physicist and bestselling author Stephen Hawking, sold over 65, copies.

In , John wrote in his Metalogicon: [2] Bernard of Chartres used to say that we are like dwarfs on the shoulders of giants, so that we can see more than them, and things at a greater distance, not by virtue of any sharpness of sight on our part, or any physical distinction, but because we are carried high and raised up by their giant size. Dicebat Bernardus Carnotensis nos esse quasi nanos, gigantium humeris insidentes, ut possimus plura eis et remotiora videre, non utique proprii visus acumine, aut eminentia corporis, sed quia in altum subvenimur et extollimur magnitudine gigantea. According to medieval historian Richard Southern , Bernard is comparing the modern scholar 12th century to the ancient scholars of Greece and Rome: [3] [The phrase] sums up the quality of the cathedral schools in the history of learning, and indeed characterizes the age which opened with Gerbert — and Fulbert — and closed in the first quarter of the 12th century with Peter Abelard. It is a very shrewd and just remark, and the important and original point was the dwarf could see a little further than the giant. That this was possible was above all due to the cathedral schools with their lack of a well-rooted tradition and their freedom from a clearly defined routine of study. The visual image from Bernard of Chartres appears in the stained glass of the south transept of Chartres Cathedral. The tall windows under the Rose Window show the four major prophets of the Hebrew Bible Isaiah, Jeremiah, Ezekiel, and Daniel as gigantic figures, and the four New Testament evangelists Matthew, Mark, Luke, and John as ordinary-size people sitting on their shoulders.

Again if you are really interested in physics there's years more than enough of modern physics to catch up with, which even students take years to learn.

This is solid work that has reached a status that is as close to fact as possible in science. The more I read this book and bookmark to go back to later , the more I know I have to learn before beginning to understand.

I think it's worth reading it, actually. Also, I spend a lot of time staring off and thinking about what I've just read. What was their purpose? Sell the book? Alas, the publishing industry at play here again.

Even Derrida didn't go as far as claiming that the text transcended the whole of material constraints. Publicada por. There was, however, a speculation about the Earth going around the Sun by the Greek philosopher, Aristarchus, as far back as the third Century B.

There is in fact a statue of him in the island of Samos with an inscription that it was his discovery which was copied by Copernicus in A. But the Aristotlean view was so dominant that not much heed was paid to such speculation. Being a Catholic priest, Copernicus could not dare to confront the Church and the existing worldview in public for fear of inquisition.

This was left to Galileo who did for the first time confront the establishment with a truly scientific observation and invited the wrath of the Pope and the inquisition, which has been retracted only very recently in the 's. Galileo was very creative.

He was the first to use an instrumental aid to observe the sky. He believed in the heliocentric view proposed by Copernicus and wanted to prove him right by observing through a telescope, which was not invented but rather developed by him. He could see tiny dots going round the Jupiter. This clearly showed that all things do not go round the Earth and dared everyone to see for oneself.

Despite the Church and the inquisition, the geocentric view was intellectually not tenable. This paved the way for Kepler and Newton.

Galileo also made another very profound observation that the Earth pulls all bodies irrespective of their mass and composition with equal acceleration. The force responsible for pulling things down is perfectly democratic in its action on bodies.

This he was supposed to have observed by letting two bodies of different mass and substance fall from the Leaning Tower of Pisa and found that they hit the ground at the same time. This is indeed a very important and unique property that separates gravity from other forces.

Much later it was left to Einstein to make creative and imaginative use of this property to discover his theory of gravity, General Relativity GR. Like Galileo, Kepler was also the adherent of the Copernican view and analysed painstakingly the orbits of planets.

He had the good fortune of laying his hands on the valuable observational data of Tyco Brahe after his death. Tyco, who was a rich aristocrat and also a great naked-eye astronomer, was a geocentric adherent and wanted his assistant, Kepler, to prove that right. Unfortunately, he died leaving the wealth of his data to Kepler who usurped it squarely before the inheritors, who hardly knew its worth, could lay claim to it.

It was Kepler who set the stage for Newton to marvel on through his three laws of planetary motion. Planetary orbits lie in a plane and they are elliptic rather than circular. Kepler's work in particular provided an excellent springboard for Newton to formulate his famous inverse square law for gravity.
