The Grand Design is a popular-science book written by physicists Stephen Hawking and Leonard Mlodinow and published by Bantam Books in The book. Is the apparent 'grand design' of our universe evidence for a benevolent creator who The Grand Design is a book that will inform - and provoke - like no other. In this startling and lavishly illustrated book, Stephen Hawking and Leonard Mlodinow present the most recent scientific thinking about these and other abiding.

The Grand Design by Stephen Hawking and Leonard Mlodinow

Hawking is now administering the coup de grace. Carroll , writing in The Wall Street Journal , described the book as speculative but ambitious: "The important lesson of The Grand Design is not so much the particular theory being advocated but the sense that science may be able to answer the deep 'Why?

If our universe arose spontaneously from nothing at all, one might predict that its total energy should be zero.

And when we measure the total energy of the universe, which could have been anything, the answer turns out to be the only one consistent with this possibility. But data like this coming in from our revolutionary new tools promise to turn much of what is now metaphysics into physics.

Whether God survives is anyone's guess. It gets into the deepest questions of modern cosmology without a single equation. The reader will be able to get through it without bogging down in a lot of technical detail and will, I hope, have his or her appetite whetted for books with a deeper technical content. And who knows?

Maybe in the end the whole multiverse idea will actually turn out to be right! The Grand Design may sharpen appetites for answers to questions like 'Why is there something rather than nothing?

This succinct, easily digested book could perhaps do with fewer dry, academic groaners, but Hawking and Mlodinow pack in a wealth of ideas and leave us with a clearer understanding of modern physics in all its invigorating complexity.

Because everything that we call matter comes from this domain which is invisible, which is beyond space and time. All religious experience is based on just three basic fundamental ideas And nothing in the book invalidates any of these three ideas".

A century or two hence All that is needed are the laws of nature. Our concept of time begins with the creation of the universe.

Therefore if the laws of nature created the universe, these laws must have existed prior to time; that is the laws of nature would be outside of time. What we have then is totally non-physical laws, outside of time, creating a universe.

Now that description might sound somewhat familiar. Very much like the biblical concept of God: not physical, outside of time, able to create a universe. The spare and earnest voice that Mr. Hawking employed with such appeal in A Brief History of Time has been replaced here by one that is alternately condescending, as if he were Mr.

Stephen Hawking Asks, What Is Reality?

Rogers explaining rain clouds to toddlers, and impenetrable. But that doesn't stop the authors from asserting that it explains the mysteries of existence In the absence of theory, though, this is nothing more than a hunch doomed — until we start watching universes come into being — to remain untested.

The lesson isn't that we face a dilemma between God and the multiverse , but that we shouldn't go off the rails at the first sign of coincidences. 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 all. I 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! Now, if you are looking to learn more 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!

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 science.

The science is great, you will learn a ton. 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 dimensional space and the vibrating membranes? Speaking 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 line. And 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 more 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 question 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 shame.If the number of universes is only 10 to the power , then it is very much unlikely that any one of them will support life, because no universe will know which set of values the other universes have already taken, and if everything is left on chance, then there is every probability that all the universes will take only those set of values that will not support life.

Imagine this, if there was equal amounts of incriminating evidence that two people committed a crime and prosecution lawyers could build a case against both men then under MDR both are guilty of the crime irrespective of the fact that it only happened one way.

Speaking of clear teaching examples, the book is filled with ways to help the reader visualize some very hard concepts.
