Jun 09, 2012 With Benedict Cumberbatch, Stephen Hawking, Funke Adeleke, Tom Bonington. In this documentary, Stephen Hawking tries to explain what science can tell us about the meaning of life through physics, philosophical discussion,and Hawking's own unique scientific perception, he attempts to shed light on humanities most profound question. The Grand Design by Stephen Hawking pdf is a famous book on 11 dimension M theory.Free Books Mania is also on Facebook.Stephan Hawking's books pdf are considered as the most authentic scientific material on the space and universe.
For those who have spent the last couple of weeks on a caving holiday or who have been on a visit to the glaciers of Svalbard, the news that Stephen Hawking has published a new book – his first in a decade – may come as a surprise. For the rest of humanity, however, the information will by now seem as stale as a day-old pizza. Certainly, the blizzard of front-page stories that has greeted publication of the first extracts from The Grand Design has been extraordinary and, over the past two weeks, has given the scientist the kind of coverage that modern authors would sell their souls for (though for Tony Blair, this may be too late).
Stephen Hawking and Leonard Mlodinow - The Grand Design How can we understand the world in which we find ourselves? Over twenty years ago I wrote A Brief History of Time, to try to explain where the universe came from, and where it is going. But that book left some important questions unanswered. Why is there a universe – why is there.

Jul 16, 2019 The Grand Design by Stephen Hawking (PDF). A thought-provoking science book co-written by Leonard Mlodinow. Exploring the history and theories of science in finding explanations on the existence of the universe.
'Hawking: God did not create universe', the Times announced on its front page, a splash story that was followed up for several days with as much furious religious reaction that the paper's writers could muster. Other media outlets followed suit – 'Bang goes God, says Hawking', the Star announced – while rabbis, archbishops and religious historians filled letters pages and comment slots with waves of apoplectic outrage.
It has been a dispiriting experience. Setting religion against science, as the media has quite deliberately done in this case, achieves little for our attempts to understand the complexities of modern cosmology, the specific aim of Hawking and Mlodinow's book. Worse, the furore suggests that at the beginning of the 21st century, in our apparently rational, secular society, the declaration by a leading scientist that God was not involved in the universe's creation is deemed to be newsworthy and deserving of front-page headlines in national newspapers.
Nothing could be further from the truth, of course. Like most other physicists, Hawking has never expressed a need for God in his equations and has only made previous mentions to tease his readers. Fortunately, most of them have had the wit to appreciate this point. In fact, there is hardly a mention of a deity in The Grand Design. In the opening pages, there are a few mentions of clerical attempts in the middle ages to make philosophical sense of the heavens and that is about it – until we reach the last chapter.
'Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist,' Hawking and Mlodinow announce at this point. 'It is not necessary to invoke God to light the blue touch paper and set the universe going.'
And that is just about it. The rest of the book is an attempt to account for the strange nature of reality as revealed by astronomers and physicists; to reconcile the apparent absurdities of quantum mechanics with the mind-stretching features of special and general relativity; and to explain why the forces of nature are apparently fine-tuned to allow the evolution of complex creatures such as ourselves. As Hawking and Mlodinow note, only the tiniest altering of the constants that control nuclear synthesis in stars would produce a universe with no carbon and no oxygen and therefore no humans.
'Our universe and its laws appear to have a design that both is tailor-made to support us and, if we are to exist, leaves little room for alternation,' they state. 'That is not easily explained, and raises the natural question of why it is that way.' The answer, the authors say, lies with M-theory. (The M apparently stands for 'master, miracle, or mystery'. The authors are unsure which.) The vital point is that M-theory allows for the existence of 11 dimensions of spacetime that contains not just vibrating strings of matter but also 'point particles, two-dimensional membranes, three-dimensional blobs and other objects that are more difficult to picture.' Simple, really.
Crucially the laws of M-theory allow for an unimaginably large number of different universes. Thus we exist because the laws of our particular universe just happen to be tuned to the exact parameters that permit the existence of hydrogen, oxygen, carbon and other key atoms and which also generate laws that allow these entities to interact in ways that build up complex chemical combinations. Other universes are not so lucky.
M-theory is the unified theory of physics that Einstein was hoping to find, state the authors, and if it is confirmed by observation, it will be the successful conclusion to a search that was begun by the ancient Greeks when they started to puzzle about the nature of reality. 'We will have found the grand design,' Hawking and Mlodinow conclude.
It is all entertaining stuff, skilfully assembled and described in a fairly droll manner. The wave-particle duality of particles is described as being as foreign as drinking a chunk of sandstone, for example. The book is also commendably brief and by and large illuminating about the complexities of modern cosmology.

So read it to understand the universe. But if it is God you are after, my advice is to steer clear.
