EBOOK ↠ The Grand Design ç Stephen Hawking

He most recent scientific thinking about the mysteries of the universe in nontechnical language marked by both brilliance and simplicity In The Grand Design they explain that according to uantum theory the cosmos does not have just a single existence or history but rather that every possible history of the universe exists simultaneously When applied to the universe as a whole this idea calls into uestion the very notion of cause and effect But the “top down” approach to cosmology that Hawking and Mlodinow describe would say that the fact that the past takes no definite form means that we create history by observing it rather than that history creates us The authors further explain that we ourselves are the product of uantum fluctuations in the very early universe and show how uantum theory predicts the “multiverse” th Stephen Hawking is smarter than I am That's no big feat because two of my cats are smarter than I am The other cat is a certifiable idiot But Hawking is way smarter than I am The Grand Design is Hawking's explanation or less about why the universe is the way it is The answer comes down to M theory which is of a combining of explanations than one single unifying theory Many reviewers seem to think Hawking is saying there is no God but he really seems to be stating that God is irrelevant The real uestion is did we come from something or nothing The beginning of an answer involves an understanding of uantum physics and multiverses that Hawking put as well into laymen's term as we can hope for I don't pretend to understand everything in this book I'm still contemplating why the world needs hairballs But I did immensely enjoy reading this short book and can honestly say I understand a little bit

BOOK The Grand Design

The Grand DesignE idea that ours is just one of many universes that appeared spontaneously out of nothing each with different laws of natureAlong the way Hawking and Mlodinow uestion the conventional concept of reality posing a “model dependent” theory of reality as the best we can hope to find And they conclude with a riveting assessment of M theory an explanation of the laws governing us and our universe that is currently the only viable candidate for a complete “theory of everything” If confirmed they write it will be the unified theory that Einstein was looking for and the ultimate triumph of human reasonA succinct startling and lavishly illustrated guide to discoveries that are altering our understanding and threatening some of our most cherished belief systems The Grand Design is a book that will inform and provoke like no othe If you're into stuff like this you can read the full reviewEpidemic of Vanity The Grand Design by Stephen Hawking Leonard MlodinowOriginal Review 2010At university after spending thousands on tuition I then had to spend a lot over 3 years on books for my courses More than half were written by the very professors that were teaching me uite frankly it's a giant scam Those professors have already been paid for the first material through their salaries Why should we have to pay them again for copies of their pretty badly written books Yes these books are very expensive and many don't deserve to be read A few years ago I was asked to review a chapter in a research text The friend who sent me the invite told me over a drink that I was the third person asked and would I please go easy on the papers I said yes

things in motion or does science offer another explanation The most fundamental uestions about the origins of the universe and of life itself once the province of philosophy now occupy the territory where scientists philosophers and theologians meet if only to disagree In their new book Stephen Hawking and Leonard Mlodinow present t It's a funny thing being a cosmologist in the greater Los Angeles area Back when I was a partying single graduate student I'd freuently hit the town for some fun Inevitably I'd meet someone strike up a conversation and they might ask me what I did for a livingOh I'm a cosmologist Cosmetologist Cool do you do make up for movies Umnot unless rouge is a component of dark matter ba da bumI make detectors and use them to study the origins and geometry of our universe Uh No way You ever work in moviesI discovered after a few years of this that it was much easier and simpler to tell people I was Mary Poppins at Disneyland Without exception folks believed me made a joke and moved on The physics thing just cause wrinkled faces and very odd non seuiturs Once I had a guy tell me all about a distant cousin who studied shrimp in the Netherlands Freuently I'd get the physicist physician mix up Luckily no one ever showed me their rash Oh well such is the life of the lonely misunderstood cosmologistWhy am I telling you about all my misadventures in life Oh yeah to let you know that my background is observational cosmology Ie making devices detectors instruments and doing experiments in labs in Antarctica and on space born projects I'm not a theorist and most definitely not into string theorymembrane theoryM theory That stuff isn't even touched upon in most graduate programs It's esoteric wicked complicated and honestly still in a very nascent stageSo I'm not ualified to comment on M theory being THE answer to The Grand Design as Hawking and Mlodinow so insistently propose The uestion then becomes did they sell me on the idea I dunno maybe It was all so very glossed over overwhelmed by all the history and background needed to give the reader an appropriate framework Then when they finally game to the climax of the story where all the previous information should coalesce M theory barely got much of an explanation or treatment at allI got the impression they wanted to push this Grand Idea a wrap up of all previous ideas made with sweeping statements and generalizations to get press Plus if it turns out to work and be right they can point to this very thin book and say A ha That's why I removed a starNow if you are looking to learn about the science of the universe this is just the book for you They do an excellent job explaining aspects of special relativity general relativity particle physics early universe physics even my favorite field the CMB Which maddeningly they call the CMBR a very outdated term and refer to the fluctuations as being in the microwave regime even though they are sub millimeter radiation Grrr They even throw in a ton of historical context which helps the reader understand the difficulties of the field and the constantly evolving nature of scienceThe science is great you will learn a ton Really The writing is clear in that no nonsense style Hawking is so famous for Unfortunately in a few areas the explanations get really muddled to the point of incomprehensibility and I suspect that might be Mlodinow's doing since those muddled spots fall in his particular area of expertise One would expect a research scientist in the field even if she's a lowly experimentalist should be able to breeze through all their scientific lessons I found the string theory section to be really tough going with pretty poorly thought out examples But it is a very esoteric field and maybe there just aren't easy ways to help lay folks visualize the 11 dimensional space and the vibrating membranesSpeaking of clear teaching examples the book is filled with ways to help the reader visualize some very hard concepts Gravity affects space time like having a rubber sheet for your pool table then pulling down on one spot right in the middle The balls will curve around the area in much the same way that objects do near ish black holes The strings in string theory are described to be like a straw with a surface space but curled up on itself However from very far away a straw looks like a 2 dimensional lineAnd yet a few of their examples obviously fall short which I suppose all stand ins for the real thing will eventually do The one that really stood out like a a sore thumb was the balloon as expanding universe Their illustration looks like someone could take a marker and draw little galaxies on a balloon Then as the balloon is filled with air and expands all galaxies will move away from each other independently The first trouble is that the galaxies if drawn on would expand themselves which doesn't actually happen The mass and hence gravity of galaxies is a stronger force than the expansion of the universe In the text it's made clear that the galaxies have to be treated as points on the balloon but the graphic is a bit misleading Secondly the obvious uestion to the balloon is Okay the balloon expands into our 3 dimensional space so what is the universe expanding into They certainly touch on the answer later but never refer back to our balloon What a shameAt any rate here's my advice Believe their grand M theory answer or don't I don't think it matters as long as you have learned a few things about our scientific understanding of the universe along the waySince I made fun of The Industry suitors I encountered around Los Angeles I should relate a tale of the foolish physicists Create a supersymmetry of courtship mishaps or something I was at a party on campus which was completely populated by science grad students and maybe a few random stray people I met a guy he seemed nice enough so we chatted about motorcycles for a while He asked me what I studied so I very jokingly told him I was a Theoretical Cosmetologist and a student at the neighboring university which has many many women Ridiculous right The guy fell for it hook line and sinker and wanted to know details of this theoretical cosmetology So I told him all about color theory combining it with an understanding of personality traits and the effect of shadowing on first impressions Meanwhile my co workers stood behind him trying to hold in their laughter It was mean but he believed me If you ever meet me in person only believe about 63% of what I say The rest is a joke And that's a scientifically proven fact
