The first three chapters are marvelous. Friend Reviews. I was originally homeless when I first discovered this book, and living in my car with my 2 cats. Could you please contact me at rick-russell sbcglobal. So as to justify my idea for that, just take a look at his last words on this book: CDF below or as an interactive-Lite web page 4 Mb. Ellis, General Relativity:
My favourite essays were of those on black holes. The interesting thing, is that since reading this book, we have discovered the existence of hyper-giants, which weren't around when Chandresekhar devised his now famous, "Chandresekhar limit" when calculating at what conditions an imploding star would finally fold under the mass of itself and become a black hole.
It makes me wonder what this now does to his limit calculations. All in all, a superb book for the scientist and non-scientist alike.
Highly recommend. Dec 05, Ahmed Abdelhamid rated it liked it. View all 6 comments. Feb 25, Swati rated it really liked it. Language is lucid.
However, at times theories are quite complex and simple pictorial illustrations if incorporated might have had been useful. The book starts off with the ancient theories on universe evolution and gradually explains reasons for non-feasibility of the same in a structured manner. It is followed by explaining that why universe is non-static, future of stars, different evolutionary models, flaws in them, the paradox which is created if we assume singularity to be existent at the t Language is lucid.
It is followed by explaining that why universe is non-static, future of stars, different evolutionary models, flaws in them, the paradox which is created if we assume singularity to be existent at the time of bing bang, concepts of quantum gravity and imaginary time to find solutions for fundamental limitations arising because of singularity assumption, possible histories of universe and ultimately capability of string theory to resolve unsolved mysteries.
At the end author has explained that why unified theory is not possible presently but might be possible in future. Author does tried to add light humour in some parts. Fascinating read! May 27, Kaustubh rated it it was amazing. Not a novel per se but a collection of lectures by Mr Hawking, which explores the origins of the universe and tries to find the answer to "Why does the Universe exist, anyway?
Stephen Hawking tries to explain the origin of the Universe or The Big Bang without going into the technicalities and also gives a brief overview of various theories present that try to explain the state of the Universe even the String theory. The writing is simple but still multiple readings will be required to comple Not a novel per se but a collection of lectures by Mr Hawking, which explores the origins of the universe and tries to find the answer to "Why does the Universe exist, anyway?
The writing is simple but still multiple readings will be required to completely understand the full book for me atleast. Jan 26, Larissa Fauber rated it really liked it. Black holes, stars, the beauty of a supernova and the universe.
Take these together and mix them with a scientist: An explosion! A Big Bang! The theory of almost everything we are eager to understand about the beginning of the times. This review will include a brief history of this book [PUN]! Not only did Stephen Hawking describe those concepts easily in this book, but he also made us have free access to his deep studies. He was born exactly years after Galileo's death and became one o Black holes, stars, the beauty of a supernova and the universe.
He was born exactly years after Galileo's death and became one of the most influential people in the area of Cosmology. Don't you feel a little bit scary to get his work to read? Don't you have the idea that it'll be tough and appalling?
I'm here to demystify your wrong judgements towards this book! First, is it paid off to read the analysis of a scientist who is not always right?
Sure it is! For someone who admits having made a mistake in his first theory of black holes, Hawking deserves more than the knighthood offered by the Queen Elizabeth, which he declined by the way. The term black hole was coined in by the American scientist John Wheeler. I would rather grant you an excerpt from the book than trying to explain it to you: Any light emitted from the surface of the star would be dragged back by the star's gravitational attraction before it could get very far. Although we would not be able to see them because the light from them would not reach us, we would still feel their gravitational attraction.
Such objects are what we now call black holes, because that is what they are—black voids in space. A star is formed when a large amount of gas, mostly hydrogen, starts to collapse in on itself due to its gravitational attraction.
As it contracts, the atoms of the gas collide with each other more and more frequently and at greater and greater speeds—the gas heats up. Eventually the gas will be so hot that when the hydrogen atoms collide they no longer bounce off each other but instead merge with each other to form helium atoms. The heat released in this reaction, which is like a controlled hydrogen bomb, is what makes the stars shine. This additional heat also increases the pressure of the gas until it is sufficient to balance the gravitational attraction, and the gas stops contracting.
It is a bit like a balloon where there is a balance between the pressure of the air inside, which is trying to make the balloon expand, and the tension in the rubber, which is trying to make the balloon smaller. Thus, if light cannot escape, neither can anything else. Everything is dragged back by the gravitational field. So one has a set of events, a region of space—time, from which it is not possible to escape to reach a distant observer.
This region is what we now call a black hole.
Einstein had the guts to confirm that his cosmological constant was an incorrect belief, Stephen followed his steps and it may be one of the reasons we look up to them both. I do, wouldn't you? Having said that, many may think that Hawking does not believe in God, yet what we see here is that he discourses about the Big Bang Theory and gives God the credit for this event.
Along the pages you also read how the Catholic Church admits in that the Big Bang is in accordance with the Bible. The Catholic Church misperceived Copernicus and Galileo regarding their theory of the Earth being the centre of the universe and it invited some experts to advise it on cosmology in the Vatican in It was when Hawking attended this conference that his interest in the origin of the universe was reawakened.
The pope told the scientist that it was okay to study the evolution of the universe after the big bang, but they "should not inquire into the big bang itself because that was the moment of creation and therefore the work of God". From my point of view, Stephen's search for the theory of everything is his inner search to meet and understand a real God. His fascination with the universe leads his thoughts to the Hands of a creator that has put forward the laws that rule the cosmos.
So as to justify my idea for that, just take a look at his last words on this book: Well, this is only a simple review and I don't like spoilers! Do you really think I would give you "everything"? Click here to read Larissa Fauber's reviews. Audiobook was not the smart choice for this for me.
I'm not an auditory learner and didn't take this into account. So I don't think I retained any of this information. However, while I listened I was completely enthralled. He really does a great job of simplifying deluxe principles.
Thermodynamics seem to be the focus here. Sep 20, Lakpa Tashi Bhutia rated it liked it Shelves: Typically this book is for people who is inclined towards science Physics in particular. But if want to read, you can go on your own. Most of the non-science people will not find this book pleasing.
But author tries his best to make this book for everyone. By keeping mathematical equations away. View 1 comment. Mar 14, Mohamed al-Jamri rated it really liked it. En todo caso, fue lo suficientemente bueno como para querer seguir leyendo. Me parece necesario comprender al menos algo de la relatividad general y el principio de incertidumbre. I really wanted to read about science when I bought this book, and Stephen Hawking knows more about science than anyone.
Starts out simple and gets really complicated, I didn't understand the last chapters in the least, but they did make look up at the sky and think "Ooo Hawking is the personification of the science teacher I always wish I had.
He explains thinks clearly without being patronizing and wit is constantly infused into the text, making it not only fascinating but fun to read. I really stopped understanding towards the end, but if you have any interest in science and the mysteries of the universe, it's worth taking a look at.
Hawkingova predavanja pokrivaju cjelokupnu teoriju nastanka svemira, od teorije Velikog praska do teorije struna. Pleasantly accessible, for the most part. Reto Book Challenge: Un libro de o acerca de una persona con discapacidad. Aug 17, Arash rated it liked it Shelves: Excellent start, very comprehensible and enjoyable to read.
The first three chapters are marvelous. Towards the end, either it reaches my horizon limits in physics, or the author is too occupied to justify his own theories to care about the reader's understanding.
I was lost in the end. Jul 27, Iman Shabani rated it it was amazing Shelves: This definitely was a nice read.
After reading it for a second time, I can say, all-in-all it's a good starter book for most people that are not much familiar with physics. After all Stephen Hawking was not only a scientist, but also a science communicator, maybe not as much as people like Carl Sagan, or Neil Tyson, but considering his disability, a pretty good one I'd say. Some of my friends think for one to understand such a book, you need to have some understanding in concepts like general rel This definitely was a nice read.
Some of my friends think for one to understand such a book, you need to have some understanding in concepts like general relativity, or quantum physics.
While that will definitely help you have an easier time reading such a book, but the way Stephen wrote this, helped me, as someone not versed in those concepts, understand most of the topics to some extent; and so I think it can help most of you as well. One other good thing about this book, is the fact that it's a quick read, and might motivate some people to give it a shot, whom will avoid it otherwise.
This could even give you enough inertia to move to more-in-depth books on the subject.
Bottom-line, I recommend this book for you. Have a good time reading it in case you decided to. Aug 06, Vikas rated it really liked it. This book is a collection of lectures by Prof.
Hawking many years ago. No matter what you may see out there the more convoluted it is the less accurate. The true theory of everything must explain explain the universe, in terms of a collection of identical fundamental units, as the Ancient Greek philosophers suggested.
Only Squish Theory does this. Until Gravity is understood, matter will not be defined. It is an electro-dynamic response influenced by electromagnetism.
