Summary
Was there a beginning of time？ Could time run backwards？ Is the universe infinite or does it have boundaries？
These are just some of the questions considered in the internationally acclaimed masterpiece by the world renowned physicist - generally considered to have been one of the world's greatest thinkers。 It begins by reviewing the great theories of the cosmos from Newton to Einstein， before delving into the secrets which still lie at the heart of space and time， from the Big Bang to black holes， via spiral galaxies and strong theory。 To this day A Brief History of Time remains a staple of the scientific canon， and its succinct and clear language continues to introduce millions to the universe and its wonders。
This new edition includes recent updates from Stephen Hawking with his latest thoughts about the No Boundary Proposal and offers new information about dark energy， the information paradox， eternal inflation， the microwave background radiation observations， and the discovery of gravitational waves。
It was published in tandem with the app， Stephen Hawking's Pocket Universe。

Only understood half of it honestly。 But the parts I understood blew my mind。 Need to read it again someday

Not sure how to review this book， I will say this: very specialized in its focus and audience。 My bachelor's was in chemistry， and a lot of the information I covered in my degree。。。that doesn't help me understand string theory though！！ Very well written and would recommend to anyone with the interest in learning。 Not sure how to review this book， I will say this: very specialized in its focus and audience。 My bachelor's was in chemistry， and a lot of the information I covered in my degree。。。that doesn't help me understand string theory though！！ Very well written and would recommend to anyone with the interest in learning。 。。。more

Reading this book was a humbling experience for three reasons: （1） it shows the vastness and complexity of the universe， highlighting the insignificance of our existence in the grand scales of space-time; （2） it highlights the limits of human knowledge despite the “long” journey we have been through; and （3） it made me admire even more brilliance of Hawking’s mind。The book delivers what it promises: a brief history of time。 However， I often found myself lost in certain parts of the book given th Reading this book was a humbling experience for three reasons: （1） it shows the vastness and complexity of the universe， highlighting the insignificance of our existence in the grand scales of space-time; （2） it highlights the limits of human knowledge despite the “long” journey we have been through; and （3） it made me admire even more brilliance of Hawking’s mind。The book delivers what it promises: a brief history of time。 However， I often found myself lost in certain parts of the book given the complexity of the ideas presented （maybe just a result of my own limitations） as Hawking sometimes oversimplifies important explanations （maybe just another reflection of his brilliance）。 This is the reason i rated it 4 stars instead of 5。The book also takes quite a philosophical turn as Hawking questions the role of a creator in the Universe。In my opinion， this book is a good start for someone who is trying to better understand the universe we live in， introducing new theories and ideas for further digging。 I finished this book with more questions than answers。 But at least now I know better what i don’t know。。。 。。。more

3。5 stars。 A really interesting and thought-provoking read。 Some of it blew my mind especially the explanations about time。 Hawking was unbelievably clever and this can really be seen in his writing。 However I disagree against all claims that this book is for lay people！ The only reason I understood the concepts spoken about were because of my educational history in studying these topics。 Even then， it was definitely hard to follow at times。

This stuff always blows my mind。 I’m definitely not smart enough to understand most of it。 But I LOVE learning what I can through books。 Stephen Hawking was an incredible human。

Książka jest doskonałym opisem wszechświata i praw nim rządzących。 Odejmuje jedna gwiazdkę， ponieważ， jako dla całkowitego laika， nie wszystkie kwestie były dla mnie zrozumiałe。 Na pewno wrócę do tej książki za jakiś czas， uprzednio edukując się w internecie。 Porównam wtedy odbiór lektury z aktualnymi wrażeniami。

What did I think of "A Brief History of Time"？The most common question that came to my mind while reading this book was "How much of this chapter can I actually understand， comprehend and analyze？"If I could answer that quite honestly I would say that I understood around 20 to 40 percent of each chapter（also depending on what the topic of the chapter was ）， now this may be due to the fact of my age。 Currently， as I am writing this review I am 12 years old and this book is definitely not in my ag What did I think of "A Brief History of Time"？The most common question that came to my mind while reading this book was "How much of this chapter can I actually understand， comprehend and analyze？"If I could answer that quite honestly I would say that I understood around 20 to 40 percent of each chapter（also depending on what the topic of the chapter was ）， now this may be due to the fact of my age。 Currently， as I am writing this review I am 12 years old and this book is definitely not in my age group。 For any new people wanting to read this book， around my age I suggest you don't。 This doesn't mean you shouldn't later on， but I do comprehend and understand that there are people around my age or exactly my age that are very advanced in understanding complicated literature with in-depth explanations。 And yes， for those people I do suggest this book if you want to understand physics and get an overall introduction to it （The art of Science overall）。 Now， the reason I gave this book only 3 stars out of 5 is because of the same reason I stated earlier （My age）。 I do plan to revisit this book soon。。。and again when I'm older。 MY TAKE ON STEPHEN HAWKING IN THIS BOOK Stephen Hawking was a brilliant being， in multiple aspects of life， and he obviously demonstrates that throughout the whole of the book（"A Brief History of Time。"）。 We can obviously say he left this book for us and for future generations to understand the complexities of how our universe works， and that by itself is beautiful。RIP Stephen Hawking 1942-2018 。。。more

It was an interesting read， but it’s a bit all over the place。 For example， the book abruptly ends after a one-off story about Isaac Newton， which left me questioning whether I received an abridged copy。

So I'm not going to rate this。 I just can't be fair。 I read this on audio and it's a good thing I did because this probably would have been the first book I ever DNF。 The description in the Libby app said this was sort of dumbed down for regular people。 LIES！！ The only thing that really stood out for me was that the Earth is about 80 thousand million million million （ and I thing there was another million in there but I lost count） years away from colliding with the sun。 Whew！ Thank goodness！ So I'm not going to rate this。 I just can't be fair。 I read this on audio and it's a good thing I did because this probably would have been the first book I ever DNF。 The description in the Libby app said this was sort of dumbed down for regular people。 LIES！！ The only thing that really stood out for me was that the Earth is about 80 thousand million million million （ and I thing there was another million in there but I lost count） years away from colliding with the sun。 Whew！ Thank goodness！ 。。。more

The book did a great job of reminding me how unlikely and incredible it is that there's anything like consciousness in this universe。。 or that there is a universe at all！The writing can be grating and confusing。 Sometimes it feels like it was written for a pleb like me to understand， and other times， I can hardly follow。 The occasional egotistical remark or anecdote didn't help。 The book did a great job of reminding me how unlikely and incredible it is that there's anything like consciousness in this universe。。 or that there is a universe at all！The writing can be grating and confusing。 Sometimes it feels like it was written for a pleb like me to understand， and other times， I can hardly follow。 The occasional egotistical remark or anecdote didn't help。 。。。more

Sigh！ This one was a tough read。 It started off quite amicably， not being too technical， at times almost philosophical。 But as the chapters progressed， Hawking explored and presented the deeper concepts of Time and Dimensions。 I could have abandoned it for the almost 70% stuff that went over my head but I instead chose to stay for the 30% stuff that really made me appreciate the genius a world has to offer。 Science now being the backbone of human life， had once been an unexplored territory。 It t Sigh！ This one was a tough read。 It started off quite amicably， not being too technical， at times almost philosophical。 But as the chapters progressed， Hawking explored and presented the deeper concepts of Time and Dimensions。 I could have abandoned it for the almost 70% stuff that went over my head but I instead chose to stay for the 30% stuff that really made me appreciate the genius a world has to offer。 Science now being the backbone of human life， had once been an unexplored territory。 It took a lot of courage， gallons of euphoria， and tons of passion for making what it is today。 Hawking has explained and credited the architects of science and astronomy。 Having paid tribute to the past， he also introduced us to the concepts that are yet to be dissected。This book does make me wonder how trivial we are， I wanted to learn every bit but sadly couldn't digest it all。 If you just want to learn about the history of Physics， the first few chapters are a delight， you might have a hard time as you proceed。 A suggestion would be to be familiar with the terms of experimental physics before diving into this book。 。。。more

Really quick read - I mostly enjoyed it。 Never had any real interest in physics （that is to say， I just don’t understand it） so I struggled through some parts but I found it overall simple enough， even for me。

This book was not written for someone as simple as me。 This 2* rating is based on my personal experience of the audiobook。 There were some interesting parts but a very large chunk of the book went over my head and I struggled to keep up。 I'm certain it would be a much better experience for those with a background knowledge of physics and sciency stuff。 This book was not written for someone as simple as me。 This 2* rating is based on my personal experience of the audiobook。 There were some interesting parts but a very large chunk of the book went over my head and I struggled to keep up。 I'm certain it would be a much better experience for those with a background knowledge of physics and sciency stuff。 。。。more

A great an easy way to understand quite a lot of really complex concepts about the universe。 Perhaps requires a little effort in some parts。 Bur honestly it feels a lot that hearing that teacher that loves what he teaches and have all the class hooked to a very interesting subject
